Q

Describe professionalism

A

Everything that doesn’t fit into the technical/non-technical skills of being a doctor OR the rules and regulations of your job.
What the patient will remember about you - appearance, actions, behaviour (even when no one’s watching), doing the right thing for the patient.
Not just about NOT doing the wrong thing, it’s about doing good things.

Q

Describe the steps of a breast examination

A

Introduction
- wash hands
- introduce yourself
- confrim patient details
- explain examination
- gain consent
- ask about concerns/pains
- reassure that if in pain or uncomfortable exam can be adjusted or stopped
- ensure a female chaperone is present
- allow patient to undress
Patient Preparation
- Expose patient
Inspection
- Four positions to work through: sitting with hands on lap, sitting with hands behind head pushing elbows out , hands pressing into hips (contraction of pectoralis major - if masses move with chest muscle it suggests tethering to underlying tissue, this maneouvre may also accenuate puckering), leaning forward (will exacerbate dimpling, asymmetry, puckering)
- Look for aysymmetry, swelling, masses, skin changes, nipple changes, surgical scars
Nipple abnormalities
-nipple inversion is a normal finding in a significant proportion of women (e.g. congenital or weight-loss associated nipple inversion).
-however, if nipple inversion develops without a clear precipitant, the possibility of underlying pathology should be considered.
-possible pathological causes of nipple inversion include breast cancer, breast abscess, mammary duct ectasia and mastitis.
- nipple discharge is benign is most cases (e.g. pregnancy, breast-feeding) however less commonly it can be associated with mastitis or underlying breast cancer (rare).
Skin changes associated with breast pathology
- scaling of the nipple and/or areola associated with erythema and pruritis are typical features of Paget’s disease of the breast (see the example image). Paget’s disease is associated with underlying in-situ or invasive carcinoma of the breast.
-erythema of the breast tissue has a wide range of causes including infection (e.g. mastitis or breast abscess), trauma (e.g. fat necrosis) and underlying breast cancer.
- puckering of breast tissue is typically associated with invasion of the suspensory ligaments of the breast by an underlying malignancy that results in ligamentous contraction which draws the skin inwards.
- peau d’orange (dimpling of the skin resembling an orange peel) occurs due to cutaenous lymphatic oedema. The dimples represent tethering of the swollen skin to hair follicles and sweat glands. Peau d’orange is typically associated with inflammatory breast cancer.
Breast Palpation
- get patient to lie down with bed at 45 degrees
- ask patient to put the same hand as the breast you are palpating behind their head
- start on the normal side
- palpating using the flats of three fingers, pushing the fingers into the tissue and doing circular motions
- palpate in a zig-zag pattern and palpating circularly around the nipple
- ensuring to palpate the axillary tail
- note any masses or areas of tenderness
- ask patient to squeeze nipple between their thumb and index finger to check for discharge (assess colour, consistency and volume)
Nipple discharge
- milky discharge: normal during pregnancy and when breastfeeding (bilateral). Galactorrhoea (nonpuerperal lactation) is pathological and caused by the presence of a prolactinoma.
- purulent discharge: thick yellow, green or brown discharge with an offensive smell. Possible causes include mastitis and central breast abscess.
- watery and bloody discharge: several possible causes however ductal carcinoma in situ is the most important diagnosis to consider.
- repeat on the opposite breast with the corresponding hand behind the head
- if a mass is found palpate it well and describe its size, borders, location, consistency (firm etc.) mobility (tethered, mobile etc). - assess this by asking the patient to tense their chest muscles (if it moves witht he chest it is tethered to the underlying tissue), fluctance (do the sides bulge outwards when squeezed like a cyst), overlying skin changes)
Elevate the breast
- if necessary, lift the breast with your hand to inspect for evidence of pathology not visible during the initial inspection (e.g. dimpling, skin changes).
Lymph Node Palpation
- start on normal side again
- take weight of patients arm
- examine the size consistency and fixation of the glands
- repeat on the other side
- feel infraclavicular, supraclavicular, cervical, parasternal lymph nodes
Conclusion
- thank patient
- wash hands
- allow them to get redresses
Summary
- note all findings (inspection of each side and then palapation of each breast, also include any lymph node abnormalities)
- further examinations? = imaging (ultrasound or mammogram), biopsy/fine needle aspiration of any masses, further lymph node investigation

Q

Describe the steps of a thyroid examination

A

Introduction
- wash hands
- introduce yourself
- confrim patient details
- explain examination
- gain consent
- are they in any pain?
- reassure that if in any discomfort or pain the examination can be altered/stopped
Prepare Patient
- ensure patient is sitting comfortably before starting the examination
- adequately expose neck and upper sternum
General Inspection
- does the patient appear agitated, anxious, or fidgety (signs of hyperthyroidism)
- is the patient sweaty (hyperthyroidism)/
- does the skin appear dry (hypothroidism)
- are they overweight (hypothyroidism)
- are they underweight (hyperthroidism)
- clothing? hyperthyroidism = heat intolerance (wear cooler clothing), cold intolerance = hypothyroidism (warmer clothing)
- hoarse voice (can be caused by compression of the larynx due to thyroid malignancy
- mobility aids? proximal myopathy (hyperthyroidism) can result in the need for walking aids
Inspection of Hands
- ask patient to hold hands out in front of them and splay fingers
- thyroid acropachy? (red swollen digits with clubbing) - indicitive of Graves’ Disease
- peripheral tremor? (a piece of paper may make the tremor more visible) - hyperthroidism
- onycholysis (painless detachment of the nail from the nail bed) associated with hyperthyroidism
- ask patient to turn hands over
- dry skin? - hypothyroidism
- palamar erythema? - hyperthyroidism?
- sweaty plams - hyperthyroidism
- feel radial pulse (tachycardic? (hyperthyroidism), bradycardic? (hypothyroidism), irregular rhythm? (atrial fibrillation - associated with hyperthyroidism)
Inspection of Face
- sweating? - hyperthyroidism
- dry skin? - hypothyroidism
- loss of outer 1/3 of the eyebrow? - hypothyroidism
Inspection of Eyes
- inspect for exophthalmos - look at eyes from the front, both sides, and above (patient may need to look slightly up for this and you should stand behind the patient (bulging eyes) by asking the patient to look at a spot on the wall behind you - Graves’ Disease
- look for lid retraction (Graves’ Disease or other thyrotoxic states) - patient still looking at a point on the wall (sclera visible above the iris)
- inflammation of the eye (can be caused by symptoms of Graves’ Disease i.e., exophthalmos and lid retraction
- H test (ask patient to follow your finger with their eyes only which you will move in an H shape) - ask them to let you know if they experience any pain or discomfort during - observe for restriction of eye movements
- restricted movements or pain during eye movement can be indicitive of Graves’ Disease
- assess for lid lag - ask patient to follow your finger with their eyes only as you move it up then down)
Inspection of Neck
- ask patient to sit relaxed
- look for skin changes such as erythema (hyperthyroidism), scars (thyroidectomy, masses (goitre (hypothyroidism) or lymph nodes)
- ask patient to drink some water - observe for movement of any masses on swallowing
- ask patient to protrude their tongue, again assessing for movement of masses
- no movement = thyroid gland mass or lymph node
- upward movement = thyroglossal cyst
Thyroid Palpation
- stand behind pateint to palpate
- begin palapation at the thyroid cartilage (Adam’s apple)
- move downwards to the cricoid cartilage
- below the cricoid cartilage is the isthmus of the thyroid gland
- palpate the isthmus and then each lobe individually
- assess the following characteristics of the thyroid (size, symmetry, consistency, masses, palpable thrill (Graves’ Disease (increased vascularisation))
- ask pateint to protrude tongue - thyroglossal cyst will rise
- ask patient to swallow some water and assess the symmetry of the thyroid lobe elevation - asymmetry may suggest a unilateral thyroid mass
- feel local lymph nodes (submental,
submandibular,
pre-auricular,
post-auricular,
superficial cervical,
deep cervical,
posterior cervical,
supraclavicular) for lymphadenopathy (swellign fo the lymph nodes) by pressing and rollign them with the pads of 3 fingers - associated with thyroid malignancy
- if a mass is found assess position, shape, consistency, mobility
- assess for tracheal deviation (i.e., due to large goitre) - inform patient this may be uncomfortable
Percussion
- percuss the sternum - may sound dull if a mass is present i.e., large goitre extending downwards
Thyroid Auscultation
- listen to each lobe of the thyroid, while patient holds their breath, to listen for a bruit (caused due to increased vascularisation secondary to Graves’ Disease/hyperthyroidism)

Reflexes
- hyporeflexia associated with hypothyroidism
- ask patient to relax arms on lap with palms facing upwards
- test biceps reflexes on both arms
Misc
- inspect for pre-tibial myxodema (localised lesions in the skin caused by deposition of hyaluronic acid) by asking patient to expose their shins - indiciatve of Graves’ Disease
- assess for proximal myopathy (symmetrical weakness of the proximal part of the upper and/or lower lims) by asking patient to stand from sitting with arms crossed - a patient with hyperthyroidism would have proximal myopathy and be unable to do this test

Conclusion

  • thank patient
  • wash hands
  • summarise findings (anythign found on inspection and then no other peripheral stigmata of thyroid disease, any evidence of thyroid eye disease?, any goitre?
  • further examinations? TFTs (TSH and T4) and imaging

Q

Discuss treatment options for revascularisation

A

Open Surgery

•Endarterectomy

  • Removes the intima and therefore the plaque
  • The artery is then closed up with a graft (either the patient’s own great saphenous vein or a bovine pericardial graft – preferably the patient’s own tissue as the post-surgery risk is lower

Bypass Graft

  • Essentially just plumbing – starts before the blockage and ends after the blockage
  • Uses either the patient’s own great saphenous vein or a PTFE graft
  • Preferably the patient’s great saphenous vein as if infection occurs it is very difficult to handle in a PTFE graft as the graft develops a biofilm in response to infection

Endovascular

•Plain Balloon Angioplasty

  • Compresses the plaque to widen the lumen – there may need to be multiple balloon angioplasties or they may not work at all as the plaque can spring back to its original position

•Balloon Angioplasty with Stent

  • Same as a plain balloon angioplasy but they deploy a stent to keep the vessel open
  • Stents often contain metal – they are a huge thrombosis risk and therefore not often offered to people at increased risk, such as smokers, as the risk of the procedure outweighs the benefits

Q

Discuss the significance of an Abdominal Aortic Aneurysm (AAA)

A

A dilatation of the abdominal aorta, usually arising below the level of the renal arteries.

Aneurysms are usually asymptomatic and are picked up incidentally although occasionally a patient will be aware of a pulsatile abdominal mass. A national screening programme for AAA has been instituted. Aneurysms are much more common in men and so males aged 65 are invited to attend for an abdominal ultrasound to visualise the aorta.

High risk of rupture which can cause life-threatening bleeding

Ruptured AAA is associated with a triad of hypotension, back pain, and a pulsatile epigastric mass

Q

Discuss the treatment options for a AAA

A

Aneurysms which are less than 5.5 cm in diameter can safely be managed conservatively but they should be monitored on a regular basis as they tend to grow slowly. Any risk factors for atherosclerotic disease and these should be addressed

Once they reach 5.5 cm in AP diameter treatment should be considered as the risk of rupture increases. Large aneurysms may cause acute symptoms in the form of back or loin pain or collapse due to hypovolaemia. This is a sign that the aneurysm has, or is about to rupture and is a surgical emergency.

Abdominal aortic aneurysms can be repaired either by open surgical techniques where the aneurysmal artery is replaced with a synthetic graft, or by endovascular techniques where, under X-ray control, the aneurysm is excluded by placing a covered stent graft in the aortic lumen (EVAR – endovascular aneurysm repair).

Open aneursym repair

  • Vessel opened and a graft inserted
  • Graft can have ‘limbs’ to accommodate for any opening in the endogenous AA for other vessels

Endovascular aneurysm repair (EVAR)

  • Guideline is inserted from the groin area on both sides and a device implanted (device has limbs)
  • Anatomy dependent as the top area must be tubular in shape to support the device
  • Has a higher risk of leakage

Q

Discuss claudication

A

Intermittent claudication

  • Seen in less severe causes of peripheral vascular disease
  • Where patients complain of pain in the muscles of the leg on walking and this is relieved by rest
  • Patients often complain of cramping pain affecting the calf muscles and this usually indicates atherosclerotic disease in the superficial femoral artery.
  • Less commonly, they can complain of pain affecting the buttock and thigh and this usually indicates more proximal disease affecting the aorto-iliac segment.

The severity of the disease is indicated by the walking distance, the more severe the disease the shorter the distance the patient is able to walk. This will also be shorter if the patient hurries, goes up an incline or climbs stairs.

The symptoms may remain stable for months or years and a sudden deterioration usually indicates a further occlusive episode. This is often followed by a period of gradual improvement due to opening up of collateral vessels. These symptoms do not occur at rest or on standing and the differential diagnosis includes arthritis of the hip or knee or nerve root compression secondary to spinal stenosis.

If the disease process progresses the symptoms will worsen and the walking distance will reduce.

Claudication in itself is a relatively benign symptom and can usually be managed conservatively. It should, however, be viewed as a marker for generalized atherosclerotic disease.

Q

Discuss Chronic Limb-Threatening Ischaemia

A

In very severe cases the ischaemia will progress to a situation where the patient experiences symptoms at rest. This is termed chronic limb threatening ischaemia(CLTI) and is characterized by severe pain across the metatarsal heads or in the toes (at the extremity of the limb), often occurring first at night when the patient is in bed. The pain often wakes the patient and typically relief is obtained by dangling the foot over the side of the bed or getting up and standing. Some patients will sleep upright in a chair.

Revascularisation or amputation is needed to obtain long-term relief. Rest pain is always accompanied by severe claudication (<50m) if the patient is able to walk. In the most severe cases, there is insufficient blood getting down to the tissues even at rest and so trophic changes occur with ulceration or gangrene developing.

Chronic limb threatening ischaemia is therefore characterised by the triad of rest pain, ulceration and /or gangrene.

It is unusual for most patients with PVD to deteriorate to this extent. Less than 10% of patients with intermittent claudication will go on to develop critical limb ischaemia.

A history looking for symptoms of coronary and cerebrovascular disease should be sought.

Any risk factors for atherosclerotic disease should be identified and, where possible, corrected

All patients should be on an anti-platelet agent and a statin.

When patients have critical ischaemia attempted revascularization is indicated. This may be by endovascular (angioplasty +/- stenting) or open surgery (bypass) depending on the nature of the occlusive lesion. If this is unsuccessful or is not possible major amputation is usually required.

Q

Describe a peripheral pulse

A

Each contraction of left ventricle results in volume of blood ejected into arterial tree.This systolic heart contraction results in a pressure wave

Pulse represents palpable arterial pulsation after each heartbeat and is felt where an artery can be compressed against bone

Consider rate, rhythm, volume and the feeling of the arterial wall

Describe Allen’s Test

A

Occluding both the radial and ulnar arteries until the hand blanches and then releasing one artery (typically the ulnar artery (as the test is often used to assess the suitability of the radial artery for procedures and you don’t want to risk damage to the radial artery if the ulnar artery is unsuitable) and assessing if the hand pinks up again

Q

Describe Buerger’s Test

A

Buerger’s test is used in an assessment of arterial sufficiency. With the patient lying down you raise the leg until the skin pallors, the patient then dangles their leg over the side of the exam bed. In a normla limb, pallor will not occur. In an iscahemic limb, pallor will occur witht he leg raised and then rubor when the leg is dangled over the edge of the bed.

The vascular/Buerger’s angle, is the angle to which the leg has to be raised before it becomes pale, whilst lying down. In a limb with a normal circulation the toes and sole of the foot, stay pink, even when the limb is raised by 90 degrees. In an ischaemic leg, elevation to 15 degrees or 30 degrees for 30 to 60 seconds may cause pallor. (This part of the test checks for elevation pallor.) A vascular angle of less than 20 degrees indicates severe ischaemia

From a sitting position, in normal circulation, the foot will quickly return to a pink colour. Where there is peripheral artery disease the leg will revert to the pink colour more slowly than normal and also pass through the normal pinkness to a red-range colouring (rubor - redness) often known as sunset foot. This is due to the dilatation of the arterioles in an attempt to rid the metabolic waste that has built up in a reactive hyperaemia. Finally the foot will return to its normal colour. This part of the test is known as a check for rubor of dependency.

Q

Discuss the possible underlying cause/pathology of skin and nipple changes which may be seen during a breast exam

A

Scaling of the nipple and/or areola associated with erythema and pruritis are typical features of Paget’s disease of the breast. Paget’s disease is associated with underlying in-situ or invasive carcinoma of the breast.

Erythema of the breast tissue has a wide range of causes including infection (e.g. mastitis or breast abscess), trauma (e.g. fat necrosis) and underlying breast cancer.

Puckering of breast tissue is typically associated with invasion of the suspensory ligaments of the breast by an underlying malignancy that results in ligamentous contraction which draws the skin inwards.

Peau d’orange (dimpling of the skin resembling an orange peel) occurs due to cutaenous lymphatic oedema. The dimples represent tethering of the swollen skin to hair follicles and sweat glands. Peau d’orange is typically associated with inflammatory breast cancer.

Nipple inversion is a normal finding in a significant proportion of women (e.g. congenital or weight-loss associated nipple inversion). However, if nipple inversion develops without a clear precipitant, the possibility of underlying pathology should be considered. Possible pathological causes of nipple inversion include breast cancer, breast abscess, mammary duct ectasia and mastitis.

Nipple discharge is benign is most cases (e.g. pregnancy, breast-feeding) however less commonly it can be associated with mastitis or underlying breast cancer (rare).

Q

State how you would describe nipple discharge if seen during a breast exam and discuss causes/pathologies of different types of discharge

A

Assess the characteristics of the discharge:

  • Colour (e.g. blood-stained, green, yellow)
  • Consistency (e.g. thick, watery)
  • Volume

Milky discharge: normal during pregnancy and when breastfeeding (bilateral). Galactorrhoea (nonpuerperal lactation) is pathological and caused by the presence of a prolactinoma.

Purulent discharge: thick yellow, green or brown discharge with an offensive smell. Possible causes include mastitis and central breast abscess.

Watery and bloody discharge: several possible causes however ductal carcinoma in situ is the most important diagnosis to consider.

Q

Briefly describe the anatomy of the thyroid (clinically relevant anatomy)

A

Thyroid has left and right lobe connected by central isthmus

Usually found just below thyroid cartilage and moves on swallowing.

Occasionally can be found along thyroglossal duct and may move on protrusion of tongue

Can enlarge into superior mediastinum or retrosternal space

Rarely, significant enlargement can cause tracheal compression

Blood supply

  • superior thyroid artery (branch of the external carotid artery)
  • inferior thyroid artery (branch of the thryocervical trunk)
  • thyroid ima artery (an anatomical variant with varaible origin and not always present)

Venous drainage

  • superior thyroid vein (drains into the internal jugular vein)
  • middle thyroid vein (drains into the internal jugular vein)
  • inferior thyroid vein (drains into the brachiocephalic vein)
  • the three thyroid veins form a venous plexus around the thyroid gland

Lymphatic drainage

  • paratracheal nodes
  • deep cervical nodes

Q

Discuss the clinical relevance of the mobility of the thyroid and/or a thyroid mass on swallowing

A

Ask the patient to swallow some water and observe the movement of the mass:

  • Thyroid gland masses (e.g. a goitre) and thyroglossal cysts typically move upwards with swallowing.
  • Lymph nodes will typically move very little with swallowing.
  • An invasive thyroid malignancy may not move with swallowing if tethered to surrounding tissue
  • The lobes of the thyroid gland usually rises symmetricaly (asymmetrical elevation may suggest a unilateral thyroid mass).

Q

Describe a thyroglossal cyst

A

Thyroglossal cysts are the most common congenital abnormality of the neck and arise as a result of the persistence of the thyroglossal duct.

The thyroglossal duct is the tract by which the thyroid gland descends during embryological development to its final position in the front of the neck.

The tongue is attached to the thyroglossal duct, which is why thyroglossal cysts rise during tongue protrusion.

Q

Discuss the different types of goitre

A
  • Diffuse goitre: the whole thyroid gland is enlarged due to hyperplasia of the thyroid tissue.
  • Uninodular goitre: the presence of a single thyroid nodule which may be active (toxic) autonomously producing thyroid hormones (causing hyperthyroidism) or inactive.
  • Multinodular goitre: the presence of multiple thyroid nodules which may be active or inactive. Active multinodular goitres are often referred to as a toxic multinodular goitre.

Q

Describe proximal myopathy

A

Proximal myopathy is a potential complication of both multinodular goitre and Graves’ disease.

Patients develop wasting of their proximal musculature causing difficulties in tasks such as standing from a sitting position.

To screen for proximal myopathy ask the patient to stand from a sitting position with their arms crossed (to minimise their ability to mask proximal muscle weakness). Make sure to stand close to the patient to prevent them from falling. An inability to stand up would suggest proximal muscle weakness.

Q

Describe pretibial myxoedma

A

Pretibial myxoedema is a form of diffuse mucinosis in which there is an accumulation of excess glycosaminoglycans (from hyaluronic acid) in the dermis and subcutis of the skin.

It usually presents itself as a waxy, discoloured induration of the skin on the anterior aspect of the lower legs (pre-tibial region).

Pretibibial myxoedema is a rare complication of Graves’ disease

A

Use adjectives

  • Appearance: Build, posture, dress, grooming, prominent physical abnormalities
  • Behaviour: Agitated, aggressive, pacing, relaxed, withdrawn
  • Rapport: Established or not
  • Level of alertness: Drowsy, alert

Description can vary between clinicians – based on your own experiences (what does agitated look like to you? etc.)

Appearance and behaviour can change how you conduct the examination i.e., open questions may not be useful for someone giving short answers

Rapport can be difficult to establish sometimes i.e., severe depressive episode or paranoid schizophrenia

Eye contact: Poor / good / intense

Psychomotor activity: Retardation / agitation

Movements: Tremor / abnormal movements

Other signs

Mannerisms: Odd purposeful movements

Stereotypes: Non-goal directed movements

Tics: Sudden involuntary movements.

Q

Discuss the speech section of the mini MSE

A

This is an observed section of the MSE - you don’t ask questions about it.

Consider

  • Quantity - Possible descriptors: • Talkative, spontaneous, expansive, paucity, poverty.
  • Rate - Possible descriptors: • Fast, slow, normal, pressured.
  • Tone and Volume - Possible descriptors: • Loud, soft, monotone, weak, strong.
  • Fluency and Rhythm - Possible descriptors: • Slurred, clear, with appropriately placed inflections, hesitant, with good articulation, aphasic.

Consider rhythm, rate, and tone (also quantity)

  • Can you get a word in? Is it verbal diarrhoea?
  • Fluency is important in old age psychiatry – i.e., word finding difficulty
  • Fluency may be disrupted if some one has auditory hallucinations i.e., they pause speech to listen to someone/something else

Q

Discuss the mood and affect section of the mini MSE

A

Mood – sustained, subjectively experienced emotional state over a period of time (Climate)

  • Subjective / objective

Affect – a component of feeling that is short-term, reactive to internal or external circumstances and rapidly changeable (Weather)

  • Congruence of affect
  • Reactivity of affect
  • Range of reactivity
  • Stability of affect

Ask questions in sensitive/considerate words – you need to appear genuinely interested to get a genuine answer (if you don’t seem interested they might just say fine and not engage) – important to build rapport before discussing mood (don’t just jump into mood – even if they come in complaining of low mood – build rapport first)

Congruence of affect – the patients understanding of their condition, its severity etc. – does the patient feel they need to be there? If they don’t, they can be closed off and/or annoyed as they don’t feel they need help

To simplify – incongruence of affect, is when the internal thoughts/feelings/conditions don’t match the external appearance/mood

Reactivity of affect – how the patient’s affect/mood changes (are they annoyed by the conversation i.e., discussion of admission, do they explode?)

42
Q

Discuss the risk section of the mini MSE

A

Not strictly part of MSE but most will comment on risk

Do this with sensitivity (similar to breaking bad news) – can be difficult to talk about, allow for some pauses, admit your concerns about their mood (concerns of self harm, suicide, harming others, homicide)

Can use phrases such as ‘other patients who have felt this low have considered harming themselves, I’m worried you may this way’

Try normalise it – we need to know about these issues to act on them and help

Risk to self

  • suicidal ideas, ongoing plans or intent
  • Self harm
  • Self neglect, vulnerabilty etc (self neglect can occur in the elderly – they see no point carrying on so stop caring for themselves (i.e., stop eating) These feelings may occur after loss of a loved one, chronic condition, cognitive decline)

Risk to others

  • thoughts of harming others, driving risk etc.
43
Q

Discuss the thought section of the mini MSE

A

Thought form

  • The processing and organisation of thoughts
  • Speech is a measure of thought (speed, flow, coherence)
  • Is speech increased in rate or more irratic = flight of thought (they may speak faster and jump from one topic to another)
  • If not disjointed speech, can be associated with tangentility (i.e., in dementia). If disjointed, can be associated with mania
44
Q

Discuss the perception section of the mini MSE

A

Reception and processing of sensory information

45
Q

Discuss the cognition section of the mini MSE

A

How we take in information, process it and use it in our daily activities

  • Attention (Ability to sustain focus, Serial 7 test, Months of the year backwards, WORLD backwords)
  • Orientation (Do they know who they are, where they are, who you are? Time: day, date, season, month, year, Place: place, building, floor, country, Person: identify people)
  • Memory (Ability to retain information, Verbal, Registration – 3 words (apple/ table/ penny), Recall after 5 minutes, Digit span – forwards and backwards)
  • Executive function (Ability to plan, Abstract thinking, Initiating appropriate actions, Inhibiting inappropriate actions
  • Executive finction includes Judgement

●Ask patient to problem solve

●“What would you do if you lost your keys?”

●“What would you do if there was a fire?”

  • Language and praxis

Context specific – is the patient drunk? Hungover? Dehydrated? Well rested? Well fed?

46
Q

Discuss the insight and judgement section of the mini MSE

A
  • Awareness of one’s own symptoms
  • Attribution of symptoms to mental disorder
  • Appraisal or analysis of consequence of the disorder
  • Acceptance of treatment
  • In a continuum rather than all or none

May change due to treatment, severity of illness etc.

47
Q

State some common abnormalities of mood and affect and note the changes that would be noted in a mini MSE

A

Schizophrenia – incongruent/blunt/restricted

Mania – euphoric/ ecstatic / expansive/ labile

Major depressive disorder – sad/ low/ restricted

Schizophrenic patients are often restrictive – not really open to telling you information or engage

Mania – overly excited about the future, labile mood (changes very quickly – one extreme to the other within seconds)

MDD – also restrictive (they don’t think you genuinely care or don’t see the point in the conversation or trying to get better)

48
Q

Discuss thought form

A

The processing and organisation of thoughts

Speech is a measure of thought

  • Speed
  • Flow
  • Coherence
49
Q

Discuss thought content

A

Delusions

  • False fixed firm belief
  • Held in spite of evidence to the contrary
  • Not in keeping with cultural and educational setting
  • Delusions are usually to do with environment/people – can poke the patient by presenting evidence to the contrary to see if they are fixed in their belief. Consider what may be considered normal to others i.e., due to culture/beliefs

Overvalued idea

  • Not held as firmly as delusions, may be shared by others.
  • More acceptable
50
Q

Discuss delusions and List/Describe different types of delusions

A

Delusions of persecution

  • most common type of delusion
  • convinced that someone is mistreating, conspiring against, or planning to harm you or your loved one

Delusions of reference – news/tv/radio

  • the belief that un-related occurrences in the external world have a special significance for the person having the delusion

Delusions of grandeur

56
Q

Describe a Mental State Exam and its purpose

A

The mental state examination (MSE) is a structured way of observing and describing a patient’s current state of mind, under the domains of appearance, attitude, behaviour, mood, affect, speech, thought process, thought content, perception, cognition, insight and judgement.

The purpose of the MSE is to obtain a comprehensive cross-sectional description of the patient’s mental state, which when combined with the biographical and historical information of the psychiatric history, allows the clinician to make an accurate diagnosis and formulation.

57
Q

Discuss how to perform an Mental State Exam

A

Opening the consultation

  • Wash your hands and don PPE if appropriate.
  • Introduce yourself to the patient including your name and role.
  • Confirm the patient’s name and date of birth.
  • Ask the patient if they’d be happy to talk with you about their current issues.

Appearance

  • The appearance of the patient may provide some clues as to their lifestyle, current mental state and ability to care for themselves.
  • Observe the patient’s general appearance:

Distinguishing features: these may include scars (e.g. self-harm), tattoos and signs of intravenous drug use.

Weight: note if they appear significantly underweight or overweight.

Stigmata of disease: note any stigmata of disease (e.g. jaundice).

Personal hygiene: this can provide insight into the patient’s current ability to care for themselves.

Clothing: note if this is appropriate for the weather/circumstances and if the clothes have been put on correctly.

Objects: look around to see if the patient has brought any objects with them and note what they are

Behaviour

  • A patient’s behaviours may provide insights into their current mental state.
  • Engagement and rapport

Note if the patient appears engaged in the consultation and if you are able to develop a rapport with them.

Note if they appear distracted or if they appear to be engaging with hallucinations (e.g. replying to auditory hallucinations in schizophrenia).

  • Eye contact

Observe the patient’s level of eye contact and note if this appears reduced or excessive.

  • Facial expression

Observe the patient’s facial expression (e.g. relaxed, angry, disengaged).

  • Body language

Observe the patient’s body language which may appear threatening (e.g. standing up close to you) or withdrawn (e.g. curled up or hands covering their face).

Note any evidence of exaggerated gesticulation or unusual mannerisms.

  • Psychomotor activity

Observe for any evidence of psychomotor abnormalities:

Psychomotor retardation: associated with a paucity of movement and delayed responses to questions.

Restlessness: the patient may continuously fidget, pace and refuse to sit still.

  • Abnormal movements or postures

Note any abnormal movements or postures:

Involuntary movements

Tremors

Tics

Lip-smacking

Akathisias (inability to remain still, or an obvious motor restlessness or fidgetiness)

Rocking

Speech

  • Assess the patient’s speech to identify abnormalities which may indicate underlying mental health issues.

Rate of speech - Pay attention to the patient’s rate of speech:

Pressure of speech: a tendency to speak rapidly, motivated by an urgency that may not be apparent to the listener (often a manifestation of thought abnormalities such as flight of ideas, which is described later in the article).

Slow speech: may occur due to psychomotor retardation which is typically associated with major depression.

Quantity of speech - Note the quantity of the patient’s speech:

Minimal or absent speech: associated with depression.

Excessive speech: associated with mania and schizophrenia.

Tone of speech - Note the tone of the patient’s speech:

Monotonous speech: associated with conditions such as depression, schizophrenia and autism.

Tremulous speech: associated with anxiety.

Volume of speech - Note the volume of the patient’s speech.

Fluency and rhythm of speech - Note the fluency and rhythm of the patient’s speech for abnormalities:

Stammering or stuttering

Slurred speech: may occur in major depression due to psychomotor retardation.

Mood and affect

  • Mood and affect both relate to emotion, however, they are fundamentally different.

Affect represents an immediately expressed and observed emotion (e.g. the patient’s facial expression or overall demeanour).

Mood represents a patient’s predominant subjective internal state at any one time as described by them.

  • Affect is what you observe and mood is what the patient tells you.
  • Mood - A patient’s mood can be explored by asking questions such as:

“How are you feeling?”

“What is your current mood?”

“Have you been feeling low/depressed/anxious lately?”

  • Examples of mood states

Low mood

Anxious

Angry

EnragedEuphoric

Guilty

Apathetic

Affect

  • To assess affect you need to observe the patient’s facial expressions and overall demeanour.
  • Apparent emotion - Observe the apparent emotion reflected by the patient’s affect, examples may include:

Sadness

Anger

Hostility

Euphoria

  • Range and mobility of affect - Range and mobility of affect refer to the variability observed in the patient’s affect during the assessment. Abnormalities may include:

Fixed affect: the patient’s affect remains the same throughout the interview, regardless of the topic.

Restricted affect: the patient’s affect changes slightly throughout the interview, but doesn’t demonstrate the normal range of emotional expression that would be expected.

Labile affect: characterised by exaggerated changes in emotion which may or may not relate to external triggers. Patients typically feel like they have no control over their emotions.

  • Intensity of affect - A patient’s intensity of affect may be described as:

Heightened: associated with mania and some personality disorders.

Blunted or flat: associated with schizophrenia, depression and post-traumatic stress disorder.

  • Congruency of affect - Note if the patient’s affect appears in keeping with the content of their thoughts (known as congruency). A patient sharing distressing thoughts whilst demonstrating a flat affect or laughing would be described as showing incongruent affect. Incongruent affect is typically associated with schizophrenia.

Thought

  • Thought can be described in terms of form, content and possession.
  • Thought form - Thought form refers to the processing and organisation of thoughts.
  • Speed of thoughts - Patient’s may demonstrate abnormally fast (i.e. racing) or abnormally slow thought processing.
  • Flow and coherence of thoughts

In healthy individuals, thoughts flow at a steady pace and in a logical order. However, in several mental health conditions, the flow and coherence of thoughts can become distorted.

  • Abnormalities of thought flow and coherence include:

Loose associations: moving rapidly from one topic to another with no apparent connection between the topics.

Circumstantial thoughts: these are thoughts which include lots of irrelevant and unnecessary details.

Tangential thoughts: digressions from the main conversation subject, introducing thoughts that seem unrelated, oblique, and irrelevant.

Flight of ideas: there is an accelerated tempo of speech often referred to as ‘pressure of speech’. In addition to the increased rate of delivery, the language employed is characterised by a wealth of associations, many of which seem to be evoked by more or less accidental connections… the excited speech wanders off the point following the arbitrary connections, and the coherent progression of ideas tends to become obscured.

Thought blocking: sudden cessation of thought, typically mid-sentence, with the patient being unable to recover what was previously said.

Perseveration: refers to the repetition of a particular response (such as a word, phrase or gesture) despite the absence/removal of the stimulus (e.g. a patient is asked what their name is and they then continue to repeat their name as the answer to all further questions).

Neologisms: words a patient has made-up which are unintelligible to another person.

Thought content

  • Abnormalities of thought content can include:

Delusions: a firm, fixed belief based on inadequate grounds, not amenable to a rational argument or evidence to the contrary and not in sync with regional and cultural norms. These may include persecutory delusions, in which the patient erroneously believes another individual or group is trying to harm them or ideas of reference, in which the individual incorrectly believes specific events relate to them.

Obsessions: thoughts, images or impulses that occur repeatedly and feel out of the person’s control. The patient is aware these obsessions are irrational, but the thoughts continue to enter their head.

Compulsions: repetitive behaviours that the patient feels compelled to perform despite recognising the irrationality of the behaviour.

Overvalued ideas: a solitary, abnormal belief that is neither delusional nor obsessional in nature, but which is preoccupying to the extent of dominating the sufferer’s life (e.g. the perception of being overweight in a patient with anorexia nervosa).2

  • Suicidal thoughts
  • Homicidal/violent thoughts
  • Some examples of questions which can be used to screen for thought content abnormalities include:

“What’s been on your mind recently?”

“Are you worried about anything?”

“Do you sometimes have thoughts that others tell you are false?”

“Do you have any beliefs that aren’t shared by others you know?”

“Do you ever feel that people are out to do you harm?”

“Do you ever feel that specific events in the world are related to you in some way?”

“Are there any thoughts you have a hard time getting out of your head?”

“Do you sometimes feel the need to perform certain behaviours repetitively, despite understanding these are irrational?”

“Do you ever think about ending your life?”

“Have you ever felt your life was not worth living?”

“Have you ever attempted to end your life?”

“Do you ever think about harming others?”

  • Thought possession - Abnormalities of thought possession include:

Thought insertion: a belief that thoughts can be inserted into the patient’s mind.

Thought withdrawal: a belief that thoughts can be removed from the patient’s mind.

Thought broadcasting: a belief that others can hear the patient’s thoughts.

  • Some examples of questions which can be used to screen for thought possession abnormalities include:

“Do you think people can put ideas in your head, without your control?”

“Have you ever felt like people have removed memories or thoughts from your mind?”

“Do you ever feel like others can hear what you’re thinking?”

Perception

  • Perception involves the organisation, identification and interpretation of sensory information to understand the world around us. Abnormalities of perception are a feature of several mental health conditions.
  • Abnormalities of perception include:

Hallucinations: a sensory perception without any external stimulation of the relevant sense that the patient believes is real (e.g. the patient hears voices but no sound is present).

Pseudo-hallucinations: the same as a hallucination but the patient is aware that it is not real.

Illusions: the misinterpretation of an external stimulus (e.g. mistaking a shadow for a person).

Depersonalisation: the patient feels that they are no longer their ‘true’ self and are someone different or strange.

Derealisation: a sense that the world around them is not a true reality.

  • Some examples of questions which can be used to screen for perceptual abnormalities include:

“Do you ever see, hear, smell, feel or taste things that are not really there?”

“Did you think this was real at the time?”

“Do you still believe it was real?”

“Do you ever feel like you’ve changed or that you don’t recognise the person you currently are?”

“Do you ever feel like the world around you isn’t real?”

Cognition

  • Cognition refers to “the mental action or process of acquiring knowledge and understanding through thought, experience, and the senses”. Cognition can be impaired as a result of mental health conditions and their treatments.
  • Throughout the process of performing a mental state examination, you will develop a vague idea of the patient’s cognitive performance including:

whether they are orientated in time, place and person

what their attention span and concentration levels are like

what their short-term memory is like

  • A formal assessment of cognition can be achieved through a variety of different validated clinical tests including:

Mini-mental state exam (MMSE)

Abbreviated mental test score (AMTS)

Addenbrooke’s cognitive examination III (ACE-III)

Insight and judgement

  • Insight - Insight, in a mental state examination context, refers to the ability of a patient to understand that they have a mental health problem and that what they’re experiencing is abnormal. Several mental health conditions can result in patients losing insight into their problem.

Some examples of questions which can be used to assess insight include:

“What do you think the cause of the problem is?”

“Do you think you have a problem at the moment?”

“Do you feel you need help with your problem?”

  • Judgement - Judgement refers to the ability to make considered decisions or come to a sensible conclusion when presented with information. Judgement can become impaired in several mental health conditions leading to poor decision making.

You may get some idea of the patient’s judgement abilities as you move through the mental state examination, but you can also specifically assess judgement by presenting the patient a scenario such as:

“What would you do if you could smell smoke in your house?”

Sensible judgement in this situation would involve leaving the house immediately wherever possible and calling the fire department. A patient with impaired judgement may suggest ignoring it.

Closing the consultation

  • Ask the patient if they have any questions or concerns that have not been addressed.
  • Thank the patient for their time.
58
Q

List and Describe formal thought disorders

A

Flight of ideas - moving rapidly between unrelated topics, increased speech rate

Loosening of association - moving between loosely related topics but fluently

Circumstantial - overly detailed speech with eventual return to the topic of focus after many digressions (can indicate schizophrenia or dementia)

Tangentiality - continuous diversion from the topic of focus with no return to it.

Clanging - thoughts connected by association of similar sounds (e.g. compulsive rhyming), often seen in mania

Punning

Word salad - an incoherent mix of words and phrases but the speech is interuptable (can indicate Wernicke’s area lesion, schizophrenia, dementia

Retardation of thinking/poverty of thought - give brief and unelaborated responses to questions. People with this form of thought disorder rarely speak unless prompted. Alogia is often seen in people with dementia or schizophrenia.

Perseveration - continued repetition of a word or phrase after it is no longer appropriate to respond in this way.

Q

Discuss the differences between true hallucinations and pseudo-hallucinations

A
61
Q

Discuss auditory hallucinations

A

Elementary - the perception of sounds such as hissing, whistling, an extended tone, and more.

First person - (i.e. audible thoughts) patients hear their own thoughts spoken out loud as they think them

Second person - patients hear a voice, or voices, talking directly to them

Third person - patients hear voices talking about themselves, referring to them in the third person, for example “he is an evil person”. This type of auditory hallucination is particularly associated with schizophrenia

62
Q

Discuss visual hallucinations

A

Usually an organic cause

Lilliputin hallucination - a hallucination in which things, people, or animals seem smaller than they would be in real life

Charles Bonnet Hallucinations - occur when people who have lost a lot of vision to see things that aren’t really there CBS hallucinations are only caused by sight loss and aren’t a sign of a mental health condition. These hallucinations are not usually distressing and people often learn to acept that they have hallucinations and that the images they see are not real (even though they may appear so)

Hypnopompic and hypnagogic hallucinations - Hypnopompic hallucinations are hallucinations that occur in the morning as you’re waking up. They are very similar to hypnagogic hallucinations, or hallucinations that occur at night as you’re falling asleep. When you experience these hallucinations, you see, hear, or feel things that aren’t actually there. Sometimes these hallucinations occur alone, and other times they occur in conjunction with sleep paralysis. These can be completely normal but are more commin in people with sleep disorders such as insomnia

63
Q

Briefly describe Charles Bonnet Syndrome

A

Charles Bonnet syndrome (CBS) is a common condition among people who’ve lost their sight. It causes people who have lost a lot of vision to see things that aren’t really there – medically known as having a hallucination.

CBS hallucinations are only caused by sight loss and aren’t a sign that you have a mental health problem.

CBS is caused by loss of vision and the way your brain reacts to this loss.When your sight is good and you are seeing real things around you, the information received from your eyes actually stops the brain from creating its own pictures.

When you lose your sight, however, your brain isn’t receiving as much information from your eyes as it used to. Your brain can sometimes fill in these gaps by creating new fantasy pictures, patterns or pictures. When this happens, you experience these pictures as hallucinations.

CBS tends to start in the weeks and months following a big deterioration in your sight.

hallucinations can be of almost anything you can think of – they can range from simple patterns, shapes or colours, to vivid detailed pictures of people, animals, objects or buildings.

CBS hallucinations only affect sight, which means the patient won’t hear, smell or feel things that aren’t there. Usually with CBS people are aware – or can learn to recognise – that what theyx’re seeing isn’t real even though it’s very vivid. People with CBS don’t usually develop complicated thoughts or ideas about why they are seeing things.

There is currently no cure for CBS

64
Q

Discuss tactile hallucinations

A

Tactile hallucination is the false perception of tactile sensory input that creates a hallucinatory sensation of physical contact with an imaginary object.

It is caused by the faulty integration of the tactile sensory neural signals generated in the spinal cord and the thalamus and sent to the primary somatosensory cortex (SI) and secondary somatosensory cortex (SII).

Tactile hallucinations are recurrent symptoms of neurological diseases such as schizophrenia, Parkinson’s disease, Ekbom’s syndrome and delerium tremens.

Patients who experience phantom limb pains also experience a type of tactile hallucination.

Tactile hallucinations are also caused by drugs such as cocaine and alcohol.

65
Q

List and Briefly describe formal tests of cognition

A

Completed after a MSE when you have concerns about cognition

MOCA

  • The Montreal Cognitive Assessment (MoCA) is a brief cognitive screening test with high sensitivity and specificity for detecting Mild Neurocognitive Disorder / Mild Cognitive Impairment (MCI). The MoCA is particularly useful for detecting cognitive changes in those with higher levels of education, or where mild cognitive changes are the primary clinical concern.
  • The MoCA is best used for screening for mild neurocognitive disorder (i.e. - mild cognitive impairment). Cognitive tests are not diagnostic, and require interpretation by a clinician in conjunction with other factors, including a patient’s clinical history, risk factors, and investigations.
  • Maximum of 30 points - a final total score of 26 and above is considered normal (Add 1 point to the score of an individual who has 12 years or fewer of formal education)

Mini-ACE

  • The Mini-ACE is a brief cognitive screening test that evaluates four main cognitive areas (orientation, memory, language and visuospatial function).
  • It is quick and easy to use

Addenbrooke’s cognitive examination

  • The Addenbrooke’s Cognitive Examination (ACE) and its subsequent versions (Addenbrooke’s Cognitive Examination-Revised, ACE-R and Addenbrooke’s Cognitive Examination III, ACE-III) are neuropsychological tests used to identify cognitive impairment in conditions such as dementia.
  • The current version of the test is the Addenbrooke’s Cognitive Examination-III (ACE-III). This consists of 19 activities which test five cognitive domains: attention, memory, fluency, language and visuospatial processing.

Q

Describe a safe approach and how to check a patient’s responsiveness

A

Ensure personal safety

  • There are very few reports of harm to rescuers during resuscitation
  • Your personal safety and that of resuscitation team members is the first priority during any resuscitation attempt
  • Check that the patient’s surroundings are safe.
  • Put on gloves as soon as possible. Other personal protective equipment (PPE) (eye protection, face masks, aprons, gowns) may be necessary especially when the patient has a serious infection such as Covid-19. Follow local infection control measures to minimise risks.
  • Be careful with sharps; a sharps box must be available.
  • Use safe handling techniques for moving patientsduring resuscitation.

Check the patient for a response

  • If you see a patient collapse or find a patient apparently unconscious assess if he is responsive (shake and shout). Gently shake his shoulders and ask loudly: “Are you all right?”
  • If other members of staff are nearby it will be possible to undertake several actions simultaneously.

If the patient responds

  • Urgent medical assessment is required
  • Call for help according to local protocols. This may include calling a resuscitation team (e.g. medical emergency team (MET).
  • Give the patient oxygen. Use a pulse oximeter to guide oxygen therapy.
  • Attach monitoring: a minimum of pulse oximetry, ECG and blood pressure.
  • Prepare for handover using SBAR (Situation, Background, Assessment, Recommendation) or RSVP (Reason, Story, Vital signs, Plan)

If the patient does not respond

  • Shout for help (if not done already).
  • Turn the patient on to their back.
  • Begin an ABCDE assessment.
67
Q

Discuss the ABCDE assessment

A

Airway, breathing and circulation should all be assessed using the ‘look, feel, listen, measure, treat’ algorithm.

  • ‘Measure’ usually involves taking vital observations, as well as bedside investigations and basic imaging.
  • ‘Treat’ involves administering any urgent treatment to counteract each abnormal finding.

Treat and reassess at each stage of ABCDE - do not move on to the next stage unless you are satisfied you have optimised any abnormalities your have found. For example, don’t assess breathing and circulation if you have found an airway obstruction that hasn’t been dealt with

Vitally, consider calling for help at EVERY STAGE of this process.

First shout for help and then approach with care

D: Assess for danger

R: Evaluate patient response

A: Airway and B:Breathing

  • If the patient is talking then the airway is patent
  • If not - put your face sideways by the patient: Look for:
    • Obstructions in the airway
    • Chest movements
    • Cyanosis
  • Feel for:
    • Breath on your cheek
    • Listen for:
      • Breath sounds
      • Stridor (inspiratory)
      • Wheeze (expiratory)
      • Gargling
  • If there is no patent airway - call for help! Give your name, location and the event.
  • Treat:
    • Remove any solid obstructions with Magill forceps
    • Remove liquid obstructions with a Yankauer sucker
    • Consider airway manuveres such as a head-tilt/chin-lift or jaw-thrust
    • If required insert an airway adjunct such as a nasopharyngeal tube or if GCS10 l/min via an oxygen mask and reservoir bag
    • If the patient has COPD, give 35% oxygen via a Venturi variable valve mask and reservoir bag until you have an ABG (reassess)
    • Aim to keep sats >94% unless known CO2 retainer
    • Monitor effectiveness with ABGs
    • If anaphylaxis with bronchospasm - consider adrenaline/steroids
    • If infection - consider antibiotics
    • If wheeze - consider salbutamol
  • Consider asking for further help, e.g.: do you need to consider non-invasive ventilation/intubation
  • Reassess!

C: Circulation

  • Look for:
    • Pallor (anaemia?)
    • Visible blood loss
    • Cyanosis
    • Sweating
    • Jugular venous pressure
  • Feel for:
    • Peripheral perfusion (is the hand cold?)
    • Peripheral capillary refill
    • Pulse rate and character
    • Peripheral oedema
  • Listen for:
    • Heart sounds (gallop/third heart sound of failure/significant murmur)
  • Measure:
    • Temperature
    • Heart rate
    • Blood pressure
    • Urine output
    • Central capillary refill time
  • Treat:
    • 2 wide bore IV cannulae in the ante-cubital fossae
    • Take bloods as necessary (eg FBC, U&Es, LFTs, Crossmatch, Clotting, Cultures, Toxicology screen, Calcium, Magnesium)
    • IV fluids: fast if signs of shock (250mls stat fluid challenge)
    • Blood if active blood loss (if urgent, O -ve until crossmatched blood arrives)
    • Antipyrexial medication (paracetamol) if appropriate
    • Consider catheterisation, and strict fluid input/output chart
  • Reassess!
  • Take care with fluids in: cardiogenic shock (raised JVP, crackles, swollen ankles, sacral oedema), renal failure (check U&Es and refer to renal team), post renal failure

D: Disability

  • Consciousness:
    • AVPU: alert/responds to voice/responds to pain/unresponsive
    • Formal GCS if response impaired
    • Blood glucose level (Don’t Ever Forget Glucose!) - if low give PO/IV glucose, if high consider sliding scale

E: Exposure

  • Top to toe examination
    • Look for any signs of haemorrhage, bruising, infection, injury, etc.
    • Examine for gross neurological deficit
    • Check for pupillary response and papilloedema

Next step:

  • Continuous reassessment
  • Discuss with seniors and ITU (if not already involved)
  • Look at patient’s notes and charts
  • Gather collateral history - ‘AMPLE’
    • Allergies
    • Medications
    • Past medical history
    • Last oral intake
    • Events leading up to deterioration
    • Review results of routine investigations (including biochemistry, microbiology, haematology, radiology, ECG, ABG
68
Q

Describe how to check for airway obstruction

A

Conscious patients with airway compromise typically sit upright intuitively.

In unconscious patients, look for abnormal chest and abdominal wall movement, suggesting airway obstruction and the lack of fogging of the oxygen mask. Listen for the snoring noise of partial airway obstruction

Also look/listen for

  • choking sounds
  • swollen lips (consider anaphalaxis)
  • possible cause of aspiration i.e., vomit
  • foreign body i.e., food
  • patient going pale/blue
69
Q

Describe how to simultaneously open the airway, check breathing and check pulse

A

Tilt the patient’s head up with one hand

Place the side of your face above the patient’s nose/mouth to listen for breath sounds, feel breath on the side of your face, and watch for chest rise and fall

Use the other hand to check the carotid pulse

70
Q

Describe how to complete the jaw thrust and chin lift manoeuvres

A

Jaw thrust

  • Standing behind the head of the patient, place the 4 fingers of each hand under the angle of the mandible/jaw and gently pull forward - use the thumbs to stabilise yourself
  • Can also be done when holding the mask of a bag
    • thumb and index fingers in a C-shape aroung the mask
    • middle fingers stabilising
    • ring and pinky fingers under the angle of the mandible/jaw and gently lifting

Chin lift

  • Tilting the patients chin up
  • Can be maintained either by continual holding or placing a pillow under the head/neck
  • Use gentle movements in patient’s with fixed neck deformities.

The chin-lift is suitable for those patients who, with an open airway, are breathing adequately. A high flow oxygen mask can be applied.

A jaw thrust is more suitable for patients who require bag-mask ventilation, since it is difficult to apply a mask and a chin-lift simultaneously.

Since movement of the head and neck is contraindicated in the context of suspected significant cervical spine injury, use a jaw thrust, not the chin-lift manoeuvre (or indeed a pillow)

71
Q

Discuss the use of suction in airway management

A

Unconscious patients are vulnerable to aspiration from:

  • Vomit
  • Blood
  • Secretions

Use gentle suction under direct vision to remove these with a wide bore rigid sucker.

When faced with an actively vomiting or regurgitating patient, or where there is a significant amount of blood in the airway, turn the patient on their side and tip the trolley head down.

Taking the sucker off the end of the suction tube may help clear thick undigested food, otherwise the sucker becomes blocked.

Turning the unconscious patient on their side and tipping the trolley head down may be the best way of avoiding aspiration

Suction can also be used to remove fluid/secretions from airway adjuncts such as a nasopharynx tube or an oropharynx tube

72
Q

Describe the location of the carotid pulse

A

The carotid pulse can be located between the larynx and the anterior border of the sternocleidomastoid muscle.

73
Q

State the hospital emergency telephone number

A

77
Q

Descrube how to use simple airway adjuncts

A

The oropharyngeal and nasopharyngeal airways are designed to address airway obstruction.

In most patients, the oropharyngeal airway (in particular) produces the same result as a jaw thrust. In such circumstances oxygen can be applied via an oxygen mask.

Oropharyngeal airway

  • The correct size oropharyngeal airway should reach from the patient’s incisors, to the angle of the jaw
  • The flanged front end of the oropharyngeal airway should sit just in front of the teeth
  • Method:
    1. Insert curved side uppermost, twisting it through 180 once inserted halfway
    1. The flanged front end should sit just in front of the teeth
    1. Confirm an improvement in ventilation has been achieved Note: An oropharyngeal airway may precipitate vomiting or rarely, laryngospasm. In both situations, remove it promptly.

Nasopharyngeal airway

  • The key advantage over the oropharyngeal airway is the ability of the nasopharyngeal airway to relieve airway obstruction in those patients whose mouths are difficult to open, typically patients undergoing a seizure.
  • Unless it is too long, it is unlikely to stimulate the oropharynx and is better tolerated in lighter patients. The disadvantage of a nasopharyngeal airway is occasional nasal haemorrhage as a complication.
  • Method:
    1. Lubricate the tube with gel and insert into the right nostril aiming gently towards the occiput, curved side down, with a little twisting motion if necessary
    1. Change to a smaller airway if there is firm resistance
    1. Check for bleeding in the oropharynx
    1. Check for improvement in airway patency

Having secured a patent airway, ask yourself whether the patient needs:

  • Ventilation
  • An oxygen mask
  • You can subjectively gauge the adequacy of the patient’s spontaneous ventilation by the depth and rate of chest wall movement.

IGEL

  • Makes one-hand bagging easier/possible
  • Tube is inserted with gel-end sitting above epiglottis
  • Bag attached to the need of the tube
78
Q

Describe how to use a bag-valve-mask ventilation

A

If ventilation is required you will need:

  • The correct size facemask, which is one that fits snugly from the bridge of the nose to just above the chin
  • A self-inflating bag

Method

  • Check the airway does not need suctioning first, then:
      1. Apply the mask firmly to the patients face using the index finger and thumb in a capital C shape
      1. Hook the little finger under the angle of the mandible and grip more mandible with the ring and middle fingers
      1. Raise the spread fingers to effect the jaw thrust
      1. Squeeze the bag firmly with the right hand, release, pause and repeat at a rate of 10 breaths per minute
79
Q

Describe the process of cardiopulmonary resuscitation

A

If you find an unconcious patient with no signs of life

Call for help

30 chest compressions (100-120bpm)

2 rescue breaths

Repeat

If an AED or defibrillator is available use and deliver shocks if appropriate

80
Q

Describe the process of two-rescuer cardiopulmonary resuscitation

A
  • Start CPR and get a colleague to call the resuscitation team, and request an AED and the emergency trolley, on the emergency number – 2222

Chest compressions in a patient whose heart is still beating are unlikely to cause harm. However, delays in diagnosing cardiac arrest and starting CPR will adversely affect chances of survival and must be avoided, so if there is any doubt proceed as if there are no signs of life and no pulse.

  • Give 30 chest compressions followed by 2 ventilations.
  • If possible the person doing chest compressions should change about every 2 min or sooner if they are unable to maintain high quality chest compressions. This change should be done with minimal interruption to compressions. This should be done during planned pauses in chest compression such as during rhythm assessment or administration of breaths.
  • Use whatever equipment is available immediately for airway and ventilation (e.g. a bag-valve mask).
  • Use an inspiratory time of about 1 second and give enough volume to produce a visible rise of the chest wall. Avoid rapid or forceful breaths.
  • Add supplemental oxygen as soon as possible.
  • If a defibrillator is available:
  • One continue compressions and breaths in 30:2 ratio or uninterrupted chest compressions if breath administration not possible
  • One rescuer set up the defibrillator and stick pads onto patient’s chest
  • Plan actions before pausing CPR for rhythm analysis and communicate these to assistant/team
  • Stop chest compressions to analyse and confirm rhythm from the ECG. If VF/VT then this can be considered a ‘shockable rhythm.’
  • This pause in compressions should not be longer than 5 seconds
  • Resume chest compressions immediately; warn all rescuers other than the individual performing the chest compressions to “stand clear” and remove any oxygen delivery device as appropriate
  • The designated person selects the appropriate energy on the defibrillator and presses the charge button. Choose an energy setting of at least 150 J for the first shock, the same or a higher energy for subsequent shocks, or follow the manufacturer’s guidance for the defibrillator. If unsure of the correct energy level for a defibrillator choose the highest available energy.
  • Ensure that the rescuer giving the compressions is the only person touching the patient.
  • Once the defibrillator is charged and the safety check is complete, tell the rescuer doing the chest compressions to “stand clear”; when clear, give the shock.
  • After shock delivery immediately restart CPR using a ratio of 30:2, starting with chest compressions.
  • Continue CPR for 2 min and then pause again to reassess rhythm and consider another defibrillation.
  • Repeat this 2 min CPR – rhythm/pulse check – defibrillation sequence if shockable rhythm persists (VF/VT).
  • Continue until senior help arrives.
  • If a non-shockable rhythm (pulseless electrical activity or asystole) then continue CPR 30:2 until senior help arrives.
  • The interval between stopping compressions and delivering a shock must be minimised. Longer interruptions to chest compressions reduce the chance of a shock restoring a spontaneous circulation. Chest compressions are resumed immediately after delivering a shock (without checking the rhythm or a pulse) because even if the defibrillation attempt is successful in restoring a perfusing rhythm, it is very rare for a pulse to be palpable immediately after defibrillation.
81
Q

Discuss the flow chart followed if a collapsed patient is found in a hospital setting

A
82
Q

State the appropriate reasons to stop CPR (in a hospital setting)

A

Reasons to stop CPR efforts:

  • Return of Spontaneous Circulation (ROSC) – patient shows signs of life
  • Rescuer exhaustion or it is no longer safe to continue CPR
  • Senior help takes over or declares death
83
Q

Describe safe defibrillation with AED

A

If a defibrillator is available:

  • If more than one rescuer, one continue compressions and breaths in 30:2 ratio or uninterrupted chest compressions ifbreath administration not possible and one rescuer set up the defibrillator and stick pads onto patient’s chest
  • One pad should be stuck below right clavicle and the other in the V6 ECG position in mid-axillary line
  • Plan actions before pausing CPR for rhythm analysis and communicate these to assistant/team
  • Stop chest compressions to analyse and confirm rhythm from the ECG. If VF/VT then this can be considered a ‘shockable rhythm.’
  • This pause in compressions should not be longer than 5 seconds
  • Resume chest compressions immediately; warn all rescuers other than the individual performing the chest compressions to “stand clear” and remove any oxygen delivery device as appropriate •
  • The designated person selects the appropriate energy on the defibrillator and presses the charge button. Choose an energy setting of at least 150 J for the first shock, the same or a higher energy for subsequent shocks, or follow the manufacturer’s guidance for the defibrillator. If unsure of the correct energy level for a defibrillator choose the highest available energy.
  • Ensure that the rescuer giving the compressions is the only person touching the patient.
  • Once the defibrillator is charged and the safety check is complete, tell the rescuer doing the chest compressions to “stand clear”; when clear, give the shock.
  • After shock delivery immediately restart CPR using a ratio of 30:2, starting with chest compressions.
  • Continue CPR for 2 min and then pause again to reassess rhythm and consider another defibrillation.
  • Repeat this 2 min CPR – rhythm/pulse check – defibrillation sequence if shockable rhythm persists (VF/VT). Continue until senior help arrives.
  • If a non-shockable rhythm (pulseless electrical activity or asystole) then continue CPR 30:2 until senior help arrives.
  • The interval between stopping compressions and delivering a shock must be minimised. Longer interruptions to chest compressions reduce the chance of a shock restoring a spontaneous circulation. Chest compressions are resumed immediately after delivering a shock (without checking the rhythm or a pulse) because even if the defibrillation attempt is successful in restoring a perfusing rhythm, it is very rare for a pulse to be palpable immediately after defibrillation.
84
Q

Describe the layout of the emergency trolley

A

The emergency trolley is set up in accordance with the ABC format of assessing a collapsed patient in hospital.

The main features are:

  • Airways drawer – OPA/Guedels, Nasopharyngeal tubes, I-Gels etc.
  • Breathing drawer - Bag Valve Mask, Oxygen masks, Intubation equipment etc
  • Circulation drawer – Cannulas, blood bottles, fluid giving sets etc.
  • A defibrillator is also located on the trolley or nearby
  • Drug Box containing emergency drugs e.g. adrenaline, amiodarone etc
85
Q

State the reversible causes of cardiac arrest and briefly discuss each of them/their treatment

A
  • Potential causes or aggravating factors for which specific treatment exists must be considered during all cardiac arrests
  • For ease of memory, these are divided into two groups of four, based upon their initial letter: either H or T:
    • Hypoxia
      • Signs – blue/pale skin, previous/changes SAT changes
      • Treatment – patent airway, oxygen and ventilation
    • Hypovolaemia
      • Check for any obvious loss of fluid i.e., bleeding
      • Fluid resuscitation
  • Hyperkalaemia or Hypokalaemia, Hypoglycaemia, Hypocalcaemia, Acidaemia and other metabolic disorders
    • ABG or VBG to diagnose
    • Treat accordingly
      • Hyperkalaemia
        • Calcium gluconate or calcium chloride – to stabilise the electricity in the heart
        • Additional treatments that will commence include:
          • Insulin with glucose
          • Inhaled salbutamol
          • Sodium bicarbonate
          • These medications will help lower the blood potassium level by moving the potassium inside the cells.
        • It is important to know that a blood potassium level measures potassium outside your cells. Potassium inside a cell is less dangerous and is not measured on the blood test.
        • To rid the blood and body of too much potassium, a person must receive:
          • Haemodialysis: Blood is removed through a line in a vein. Then, it’s filtered through a dialyzer instrument and returned to the person via another line.
          • Certain diuretics, such as Lasix (furosemide), eliminate the potassium in the urine – cannot be a K sparing diuretic
  • Hypokalaemia
    • Severe or symptomatic hypokalemia can be treated promptly with oral and IV potassium.
      • The oral potassium should be used in the dose 20-40 mEq three to four times a day (the lower dose is for patients receiving IV potassium, and the higher doses for patients receiving just the oral).
      • The IV potassium can be given in a solution with normal saline (not glucose) in a concentration of 20-60 mEq/L and a rate around 10-20 mEq/h to avoid phlebitis and hyperkalemia (a central vein is a better option for a rate higher than 10 mEq/h). The potassium should be measured again after 40mEq of IV potassium (and further doses will depend on the results).
      • Continuous EEG monitoring should be provided during the treatment. Once the hypokalemia is no longer severe, the IV should be reduced or stopped (continuing only with the oral therapy).
    • As a general rule, 10mEq of potassium given may increase serum potassium by 0.1.
    • Potassium chloride is the preferred agent in most situations (except in patients with acidosis which may benefit from potassium bicarbonate).
    • Low magnesium may occur together with hypokalaemia and can make the treatment of the latter harder. In such patients, magnesium replacement should be provided as well.
  • Hypoglycaemia
    • Patients who are unconscious, having seizures, or who are very aggressive, should have any intravenous insulin stopped, and be treated initially with glucagon.
    • If glucagon is unsuitable, or there is no response after 10 minutes, glucose 10% intravenous infusion, or alternatively glucose 20% intravenous infusion should be given.
  • Hypocalcaemia
    • Intravenous (IV) calcium gluconate is the preferred therapy
  • Acidaemia
    • Treatment dependent on cause but goals of treatment include
      • excreting or getting rid of excess acids
      • buffering acids with a base to balance blood acidity
      • preventing the body from making too many acids
  • Other metabolic disorders
    • Treatment dependent on the disorder
  • Hypothermia
    • Warm fluids
    • Warming blankets
    • Not dead until they’re warm and dead
  • Thrombosis (coronary or pulmonary)
    • Chest pain
    • Blood thinners (warfarin, heparin)
  • Tension pneumothorax
    • Signs – deviated trachea, absent breath sounds on one side
    • Treatment – aspiration (go in from above 3rd rib, 2nd intercostal space in the mid-clavicular line, directing the needle upwards) and chest tube
  • Tamponade –cardiac
    • Focused cardiac echo
    • More senior/specialised colleague will treat
  • Toxins
    • Can be varied
    • Look over drug chart
    • Treat accordingly
86
Q

Discuss the ALS (adult life support) flow chart

A
87
Q

Discuss shockable rhythms and how to manage them

A
  • Ventricular fibrillation (really unorganised, large amplitude squiggle)
  • Pulseless ventricular tachycardia (organised wide QRS complexes – no P wave)
  • Treatment
    • Adrenaline given after the 3rd shock, and then every 2nd round
    • Amiodarone (K channel blocker) also given after the 3rd shock and then every 2nd round
88
Q

Discuss non-shockable rhythms and how to manage them

A
  • Pulseless Electrical Activity (PEA) – no pulse but normal electrical activity (looks fine on monitor)
  • Asystole (just a slight squiggly line) – if completely flat readjust pads
  • These rhythms are non-shockable as a shock is aimed at getting the rhythm back to normal
    • PEA – the rhythm is already normal
    • Asystole – there is no rhythm
  • Treatment
    • Adrenaline given immediately after realising rhythm is non-shockable and then every 2nd round
89
Q

Discuss the process of a PVD examination

A

Introduction

  • Wash your hands and don PPE if appropriate.
  • Introduce yourself to the patient including your name and role.
  • Confirm the patient’s name and date of birth.
  • Briefly explain what the examination will involve using patient-friendly language.
  • Gain consent to proceed with the examination.

Patient preparation

  • Adequately expose the patient’s limbs and abdomen for the examination (offer a blanket to allow exposure only when required).
  • Position the patient on the bed, with the head of the bed at 45°.
  • Ask the patient if they have any pain before proceeding with the clinical examination.

General inspection

  • Clinical signs - Inspect the patient from the end of the bed whilst at rest, looking for clinical signs suggestive of underlying pathology:
    • Missing limbs/digits: may be due to amputation secondary to critical ischaemia.
    • Scars: may indicate previous surgical procedures (e.g. bypass surgery) or healed ulcers.
  • Objects and equipment - Look for objects or equipment on or around the patient that may provide useful insights into their medical history and current clinical status:
    • Medical equipment: note any dressings and limb prosthesis.
    • Mobility aids: items such as wheelchairs and walking aids give an indication of the patient’s current mobility status.
    • Vital signs: charts on which vital signs are recorded will give an indication of the patient’s current clinical status and how their physiological parameters have changed over time.
    • Prescriptions: prescribing charts or personal prescriptions can provide useful information about the patient’s recent medications.

Upper limbs

  • Inspection - Inspect and compare the upper limbs:
    • Peripheral cyanosis: bluish discolouration of the skin associated with low SpO2 in the affected tissues (e.g. may be present in the peripheries in PVD due to poor perfusion).
    • Peripheral pallor: a pale colour of the skin that can suggest poor perfusion (e.g. PVD).
    • Tar staining: caused by smoking, a significant risk factor for cardiovascular disease (e.g. PVD, coronary artery disease, hypertension).
    • Xanthomata: raised yellow cholesterol-rich deposits that are often noted on the palm, tendons of the wrist and elbow. Xanthomata are associated with hyperlipidaemia (typically familial hypercholesterolaemia), another important risk factor for cardiovascular disease.
    • Gangrene: tissue necrosis secondary to inadequate perfusion. Typical appearances include a change in skin colour (e.g. red, black) and breakdown of the associated tissue.
  • Temperature and capillary refill time (CRT)
    • Temperature - Place the dorsal aspect of your hand onto the patient’s upper limbs to assess temperature:
      • In healthy individuals, the upper limbs should be symmetrically warm, suggesting adequate perfusion.
      • A cool and pale limb is indicative of poor arterial perfusion.
    • Capillary refill time (CRT) - Measuring capillary refill time (CRT) in the hands is a useful way of assessing peripheral perfusion:
      • Apply five seconds of pressure to the distal phalanx of one of a patient’s fingers and then release.
      • In healthy individuals, the initial pallor of the area you compressed should return to its normal colour in less than two seconds.
      • A CRT that is greater than two seconds suggests poor peripheral perfusion.
      • Prior to assessing CRT, check that the patient does not currently have pain in their fingers.
  • Pulses
    • Radial pulse
      • Palpate the patient’s radial pulse, located at the radial side of the wrist, with the tips of your index and middle fingers aligned longitudinally over the course of the artery.
      • Once you have located the radial pulse, assess the rate and rhythm, palpating for at least 5 cardiac cycles.
    • Radio-radial delay
      • Radio-radial delay describes a loss of synchronicity between the radial pulse on each arm.
      • To assess for radio-radial delay:
        • Palpate both radial pulses simultaneously.
        • In healthy individuals, the pulses should occur at the same time.
        • If the radial pulses are out of sync, this would be described as radio-radial delay.
      • Causes of radio-radial delay include:
        • Subclavian artery stenosis (e.g. compression by a cervical rib)
        • Aortic dissection
    • Brachial pulse - Palpate the brachial pulse in each arm, assessing volume and character:
      • Support the patient’s right forearm with your left hand.
      • Position the patient so that their upper arm is abducted, their elbow is partially flexed and their forearm is externally rotated.
      • With your right hand, palpate medial to the biceps brachii tendon and lateral to the medial epicondyle of the humerus
      • Deeper palpation is required (compared to radial pulse palpation) due to the location of the brachial artery.
    • Blood pressure (BP) - Measure the patient’s blood pressure in both arms
      • Wide pulse pressure (more than 100 mmHg of difference between systolic and diastolic blood pressure) can be associated with aortic regurgitation and aortic dissection.
      • A more than 20 mmHg difference in BP between arms is abnormal and is associated with aortic dissection.
    • Carotid pulse - The carotid pulse can be located between the larynx and the anterior border of the sternocleidomastoid muscle.
      • Auscultate the carotid artery
      • Prior to palpating the carotid artery, you need to auscultate the vessel to rule out the presence of a bruit. The presence of a bruit suggests underlying carotid stenosis, making palpation of the vessel potentially dangerous due to the risk of dislodging a carotid plaque and causing an ischaemic stroke.
      • Place the diaphragm of your stethoscope between the larynx and the anterior border of the sternocleidomastoid muscle over the carotid pulse and ask the patient to take a deep breath and then hold it whilst you listen.
      • Be aware that at this point in the examination, the presence of a ‘carotid bruit’ may, in fact, be a radiating cardiac murmur (e.g. aortic stenosis).
    • Palpate the carotid pulse
      • If no bruits were identified, proceed to carotid pulse palpation:
          1. Ensure the patient is positioned safely on the bed, as there is a risk of inducing reflex bradycardia when palpating the carotid artery (potentially causing a syncopal episode).
          1. Gently place your fingers between the larynx and the anterior border of the sternocleidomastoid muscle to locate the carotid pulse.
          1. Assess the character (e.g. slow-rising, thready) and volume of the pulse
    • Allen’s Test
      • Occluding both the radial and ulnar arteries until the hand blanches and then releasing one artery (typically the ulnar artery (as the test is often used to assess the suitability of the radial artery for procedures and you don’t want to risk damage to the radial artery if the ulnar artery is unsuitable) and assessing if the hand pinks up again
  • Abdomen - Ensure there is adequate exposure for abdominal examination: if the patient is wearing shorts, the waistband should be positioned to be at the level of the pubic symphysis.
  • Inspection
    • Examination of the aorta, iliac arteries and femoral arteries should be part of routine abdominal examinations
      • Inspect the abdomen looking for any obvious pulsation. The abdominal aorta can be located in the midline of the epigastrium.
      • Aorta pulsation can generally be seen in a normal patient unless the patient is obese
      • An anuerysmal aorta almost always causes visible puslation
      • on careful inspection the pulsation fo the normal aorta should be visible unless the patient is obese
      • aorta lies to the left of the IVC but lies quite centrally, bifurcating at about umbilical level
  • Palpation
    • Palpate the aorta
        1. Using both hands perform deep palpation just superior to the umbilicus in the midline.
        1. Note the movement of your fingers:
          * In healthy individuals, your hands should begin to move superiorly with each pulsation of the aorta.
          * If your hands move outwards, it suggests the presence of an expansile mass (e.g. abdominal aortic aneurysm).
          * This is a crude clinical test and further investigations would be required before a diagnosis of an abdominal aortic aneurysm was made.
          * if the patient is relaxed the aorta can usually be felt without discomfort
          * it is also important to assess the upper extend of the aneurysm as far as possible
    • Auscultation
      • Auscultate over the aortic bifurcation, over both iliac arteries, and over both femoral arteries - any audible bruits are indicitive of turbulent flow indicating disease in the underlying artery
      • Auscultate the aorta and renal arteries
        • Auscultate over the aorta and renal arteries to identify vascular bruits suggestive of turbulent blood flow:
        • Aortic bruits: auscultate 1-2 cm superior to the umbilicus, a bruit here may be associated with an abdominal aortic aneurysm.
        • Renal bruits: auscultate 1-2 cm superior to the umbilicus and slightly lateral to the midline on each side. A bruit in this location may be associated with renal artery stenosis
    • Iliac arteries
      • Can usually only be felt if they are aneurysmal or the patient is very thin but an attempt should always be made to palpate them (in the line between the umbilcus and the femoral pulse) so as not to miss an aneursym
    • Femoral arteries
      • Can be felt in easily in the groins in most cases, but in obese patients, and when the pulse is weak, it may be necessary to carefully palpate the bony landmarks in order to find the pulse
      • The ASIS and the pubic tubercle mark the ends of the inguinal ligament, and the femoral artery is palpated a little medial and a little inferior to the mid point of this ligament

Lower limbs

  • Inspection - Inspect and compare the lower limbs:
    • Peripheral cyanosis: bluish discolouration of the skin associated with low SpO2 in the affected tissues (e.g. may be present in the peripheries in PVD due to poor perfusion).
    • Peripheral pallor: a pale colour of the skin that can suggest poor perfusion.
    • Ischaemic rubour: a dusky-red discolouration of the leg that typically develops when the limb is dependent. Ischaemic rubour occurs due to the loss of capillary tone associated with PVD.
    • Venous ulcers: typically large and shallow ulcers with irregular borders that are only mildly painful. These ulcers most commonly develop over the medial aspect of the ankle.
    • Arterial ulcers: typically small, well-defined, deep ulcers that are very painful. These ulcers most commonly develop in the most peripheral regions of a limb (e.g. the ends of digits).
    • Gangrene: tissue necrosis secondary to inadequate perfusion. Typical appearances include a change in skin colour (e.g. red, black) and breakdown of the associated tissue
    • Missing limbs, toes, fingers: due to amputation secondary to critical ischaemia.
    • Scars: may indicate previous surgical procedures (e.g. bypass surgery) or healed ulcers.
    • Hair loss: associated with PVD due to chronic impairment of tissue perfusion.
    • Muscle wasting: associated with chronic peripheral vascular disease.
    • Xanthomata: raised yellow cholesterol-rich deposits that may be present over the knee or ankle. Xanthomata are associated with hyperlipidaemia (typically familial hypercholesterolaemia), another important risk factor for cardiovascular disease.
    • Paralysis: critical limb ischaemia can cause weakness and paralysis of a limb. To perform a quick gross motor assessment, ask the patient to wiggle their toes.
  • Inspect the legs
  • Inspect the back of the legs
  • Inspect between the toes
  • Assess gross motor function
  • Temperature and capillary refill time (CRT)
    • Temperature
      • Place the dorsal aspect of your hand onto the patient’s lower limbs to assess and compare temperature:
      • In healthy individuals, the lower limbs should be symmetrically warm, suggesting adequate perfusion.
      • A cool and pale limb is indicative of poor arterial perfusion.
    • Capillary refill time (CRT)
      • Measuring capillary refill time (CRT) in the lower limbs is a useful screening tool to quickly assess peripheral perfusion:
      • Apply five seconds of pressure to the distal phalanx of one of a patient’s toes and then release.
      • In healthy individuals, the initial pallor of the area you compressed should return to its normal colour in less than two seconds.
      • A CRT that is greater than two seconds suggests poor peripheral perfusion.
      • Prior to assessing CRT, check that the patient does not currently have pain in their toes.
  • Pulses - When assessing the pulses of the lower limbs work proximal to distal – this allows you to assess and compare arterial inflow into each leg. If pulses are not palpable, a doppler can be used to assess blood flow through a vessel.
    • Femoral pulse - Palpate the femoral pulse:
    • The femoral pulse can be palpated at the mid-inguinal point, which is located halfway between the anterior superior iliac spine and the pubic symphysis.
    • Check that the pulse is present and assess the pulse volume.
  • Assess for radio-femoral delay: Palpate the femoral pulse and radial pulse simultaneously.
    • In healthy individuals, the pulses should occur at the same time.
    • If the pulses are out of sync, this indicates radio-femoral delay.
  • Auscultate over the femoral pulse to screen for bruits: Bruits in this region suggest either femoral or iliac stenosis.
  • Popliteal pulse - Palpate the popliteal pulse:
    • The popliteal pulse can be palpated in the inferior region of the popliteal fossa.
    • With the patient supine, ask them to relax their legs and place your thumbs on the tibial tuberosity.
    • Passively flex the patient’s knee to 30º as you curl your fingers into the popliteal fossa. This should allow you to feel the pulse, as you compress the popliteal artery against the tibia.
    • This pulse is often difficult to palpate, so don’t pretend you can feel it if you can’t. The popliteal artery is one of the deepest structures within the fossa, so the examiner will understand if you are unable to locate the artery.
  • Posterior tibial pulse - Palpate the posterior tibial pulse:
    • The posterior tibial pulse can be located posterior to the medial malleolus of the tibia.
    • Palpate the pulse to confirm its presence and then compare pulse strength between the feet.
  • Dorsalis pedis pulse - Palpate the dorsalis pedis pulse:
    • The dorsalis pedis pulse can be located over the dorsum of the foot, lateral to the extensor hallucis longus tendon, over the second and third cuneiform bones.
    • Palpate the pulse to confirm its presence and then compare pulse strength between the feet.
  • Sensation - Slowly progressive peripheral neuropathy is common in patients with significant peripheral vascular disease. This results in a glove and stocking distribution of sensory loss. Acute critical limb ischaemia causes rapid onset parathesia in the affected limb.
    • Gross peripheral sensation assessment - Perform a gross assessment of peripheral sensation:
        1. Ask the patient to close their eyes whilst you touch their sternum with a wisp of cotton wool to provide an example of light touch sensation.
        1. Ask the patient to say “yes” when they feel the sensation.
        1. Using the wisp of cotton wool, begin to assess light touch sensation moving distal to proximal, comparing each side as you go by asking the patient if it feels the same:
      • If sensation is intact distally, no further assessment is required.
      • If there is a sensory deficit, continue to move proximally until the patient is able to feel the cotton wool and note the level at which this occurs
  • Buerger’s test - Buerger’s test is used to assess the adequacy of the arterial supply to the leg.
    • To perform Buerger’s test:
        1. With the patient positioned supine, stand at the bottom of the bed and raise both of the patient’s feet to 45º for 1-2 minutes.
        1. Observe the colour of the limbs: - The development of pallor indicates that peripheral arterial pressure is unable to overcome the effects of gravity, resulting in loss of limb perfusion. If a limb develops pallor, note at what angle this occurs (e.g. 25º), this is known as Buerger’s angle.
          * In a healthy individual, the entire leg should remain pink, even at an angle of 90º.
          * A Buerger’s angle of less than 20º indicates severe limb ischaemia.
        1. Sit the patient up and ask them to hang their legs down over the side of the bed:
          * Gravity should now aid reperfusion of the leg, resulting in the return of colour to the patient’s limb.
          * The leg will initially turn a bluish colour due to the passage of deoxygenated blood through the ischaemic tissue. Then the leg will become red due to reactive hyperaemia secondary to post-hypoxic arteriolar dilatation (driven by anaerobic metabolic waste products).
  • To complete the examination…
    • Explain to the patient that the examination is now finished.
    • Thank the patient for their time.
    • Dispose of PPE appropriately and wash your hands.
    • Summarise your findings.
  • Further assessments and investigations
    • Suggest further assessments and investigations to the examiner:
      • Blood pressure measurement: to identify significant discrepancies between the two arms suggestive of aortic dissection.
      • Cardiovascular examination: to complete assessment of the vascular system.
      • Ankle-brachial pressure index (ABPI) measurement: to further assess lower limb perfusion.
      • Upper and lower limb neurological examination: if gross neurological deficits were noted during the peripheral vascular examination.

Muscle wasting: associated with chronic peripheral vascular disease.

Paralysis: critical limb ischaemia can cause weakness and paralysis of a limb. To perform a quick gross motor assessment, ask the patient to wiggle their toes.

Look for objects or equipment on or around the patient that may provide useful insights into their medical history and current clinical status:

  • Medical equipment: note any dressings and limb prosthesis.
  • Mobility aids: items such as wheelchairs and walking aids give an indication of the patient’s current mobility status.
  • Vital signs: charts on which vital signs are recorded will give an indication of the patient’s current clinical status and how their physiological parameters have changed over time.
  • Prescriptions: prescribing charts or personal prescriptions can provide useful information about the patient’s recent medications.

  • Aortic dissection
94
Q

Discuss the clinical relevance of blood pressure in a PVD examination

A

Measure the patient’s blood pressure in both arms

  • Wide pulse pressure (more than 100 mmHg of difference between systolic and diastolic blood pressure) can be associated with aortic regurgitation and aortic dissection.
  • More than 20 mmHg difference in BP between arms is abnormal and is associated with aortic dissection.
95
Q

Discuss the importance of auscultating the carotid artery before palpating it (this is ONLY relevant when considering someone with suspected or confirmed arterial or venous disorders)

A

Prior to palpating the carotid artery, you need to auscultate the vessel to rule out the presence of a bruit. The presence of a bruit suggests underlying carotid stenosis, making palpation of the vessel potentially dangerous due to the risk of dislodging a carotid plaque and causing an ischaemic stroke.

96
Q

Discuss how to auscultate the carotid artery

A

Place the diaphragm of your stethoscope between the larynx and the anterior border of the sternocleidomastoid muscle over the carotid pulse and ask the patient to take a deep breath and then hold it whilst you listen.
