Q

What are the 4 types of shock and how are they characterised?

Which is most common?

A

Hypovolemic - too low blood volume
Cardiogenic - anything (e.g. pressure issue, cardiomyopathy, infarction) that impairs the heart generating pressure leading to inadequate tissue perfusion, which causes shock
Obstructive - Something physically obstructs the vessels preventing perfusion
Distributive - excessive vasodilation (Pressure = CO x total peripheral resistance), anything that causes massive vasodilation = fall in total peripherial resistance = fall in pressure

Hypovolemic shock = most common

Q

Dr Patel wrote in her notes:
Impression - sepsis, altered mental state likely due to that but need to consider alcohol, delirium, drugs and intracranial pathology
Plan - sepsis management, investigate source of sepsis, CT to rule out intracranial pathology

Why does Dr Patel think Bill has sepsis?

A 
Developing high temperature (may or may not have in sepsis)
Difficult to wake/Sleepier than normal
Altered mental state
Oxygen to maintain above 92% sats
Low blood pressure
From shelter/streets - poor hygiene

All other shocks = pale and weak, and not much change in temp

Q 
Bill's labs show: 
Raised CRP - 203 (normal = <5)
Raised creatinine - 145 (normal = 59-104)
Raised urea - 9.2 (normal = 2.5-7.8)
Raised GGT - 74 (normal = 0-60)
Raised lactate - 3.1 (normal = 0.5-2.2)
Ethanol - positive in serum
Raised WBC - 15.3 (normal = 4.2-10.6)
Raised neut - 9.8 (normal = 2.0-7.1)

46
Q

What organs are found in the abdomen that could be causing pain?

What conditions / organs could be causing Bill’s pain?

A

Bladder = central abdomen, kidney = higher up, or descending and sigmoid colon (in a female, the ovaries, uterus and womb are important to take into consideration)

Appendicitis
Sigmoid diverculitis
Colorectal adenocarcinoma 
Acute kidney injury 
Descending and sigmoid colon
47

Spleen = normal size. There are no ascites.

Pancreas = normal size

Kidneys = normal size and position

Multiple diverticulae in the colonic segments, sigmoid colon = thickened walls, small fluid filled mass at anterior sigmoid colon perhaps abscess formation

Free fluid within lower left quadrant

48
Q

A

Constant abdominal pain due to overgrowth of gut bacteria
Signs of systemic upset
Common cause of sepsis

Diagnosed = clinical examination blood tests and ct scan (or sometimes ultrasound)

50
Q

What is diverticulitis?

A

Out-pouching with infection/inflammation - often due to poor diet results in change in bowel movements

51
Q

What is diverticulosis?

A

Out-pouching without inflammation

52
Q

What are diverticula?

A

Abnormal out-pouching of the mucosa

53
Q

When does it become diverticular disease?

A

Intermittent abdominal pain
Changes in bowel pain
Related to a high fat, low fibre diet

54
Q

BMJ soundcloud:

What is the iceberg of homelessness?

How is this a public health issue?

A

Iceberg of homelessness:

  1. Obvious homelessness (street sleepers) - increase from 2000 to 4800
  2. Hidden homelessness - sleeping in car parks, couch surfing etc.
  3. People on the edge of becoming homeless

Homelessness = public health issue:
Most affects 1. - cold, drug use, infections, etc.
3. - anxiety, fear

55
Q

BMJ soundcloud:

What are the causes of homelessness?

A

Superficial = private renting and evictions (fams with children need to live in private renting - 8 weeks notice)

Inequality in wealth - amount of housing not being used by well-off people
Family homes still in use by older generation - leaves rooms entry

Most expensive and least well-regulated housing

Mostly an issue in London, not so much in rural areas (homelessness clearing)

56
Q

What could be done in this country to help homelessness?

A

Cuts to local authority funding = lack of hostels

Requisition of empty warehouses, put in bunk beds for the homeless

Change rent regulations - landlords should not be able to evict you with just an 8 weeks notice and not to put up rent whenever they feel like it

Lower the house prices, lower rent (sometimes rent is double a mortgage)

57
Q

What could help the homeless in terms of medical provisions?

A

Practices = deals exclusively with homeless people

GPs need to recognise: many symptoms of people = underlying stress from housing

Stigma with homelessness = do not seek help

58
Q

What does the ABCDE approach stand for and why is it used?

A

A = Airway, B = Breathing, C = Circulation, D = Disability, E = Exposure

Used to recognise life threatening issues to buy time for further treatment and diagnosis

59
Q

What are the problems, assessments and actions for the Airways?

A

Is the patient’s airway secure or compromised? Untreated = hypoxia and risks organ damage, cardiac arrest, and death.

Problems:- Decreased GCS (GCS ≤8 usually requires intubation), excessive secretions, airway swelling / inflammation, trauma

Assessment:- Paradoxical chest and abdominal movements, use of accessory muscles, noisy breathing, no breath sounds at the nose or mouth, central cyanosis (blue)

Action:- head tilt and chin lift, or jaw thrust, suction to remove debris, intubation, emergency surgical airway, give oxygen at high concentration

60
Q

What are the problems, assessments and actions for Breathing?

A

Problems:- reduced GCS, acute severe asthma / COPD, pneumonia / lung infection, pulmonary oedema, pneumothorax, pulmonary embolism, haemothorax (blood in the pleural cavity, often secondary to trauma), respiratory depression (e.g. secondary to drug toxicity)

Assessment:- Obtain oxygen saturations, count RR, talking ability, use of respiratory muscles, central cyanosis, sweating, look for symmetry of chest movement and for chest deformity, feel trachea for deviation = tension pneumothorax or large effusion on the contralateral side or collapse on the ipsilateral side, percuss the chest, hyper-resonance = pneumothorax, dullness = pleural fluid, listen to air entry and added sounds (crackles, wheeze, stridor)
consolidationcaused by complete obstruction to that region, DVT (deep vein thrombosis)

Action:- Specific treatment will depend on cause (e.g. adrenaline in anaphylaxis, chest drainage in pneumothorax, Naloxone in opioid overdose, bronchodilators in airway disease), arterial blood gas analysis is likely to be useful, sit patient up if possible and they’re short of breath, give oxygen (target >94%), use bag-mask or pocket mask ventilation to improve oxygenation and ventilation, non-invasive ventilation or intubation and ventilation

61
Q

What are the problems, assessments and actions for Circulation?

A

All emergencies = hypovolaemia is primary cause of circulatory failure (shock) until proven otherwise, breathing issues affect circulation

Problems:- hypovolaemia (bleeding, burns, diarrhoea / vomiting, dehydration), pump failure cardiogenic (e.g heart failure, myocardial infarction, arrhythmia) or non-cardiogenic (e.g cardiac tamponade, tension pneumothorax, PE), vasodilation (sepsis, anaphylaxis)

Assessment:- colour of hands, limb temperature, measure capillary refill time (normal CRT < 2 s), prolonged CRT = poor peripheral perfusion (or cold env. and old age), HR, 3-lead cardiac monitoring (or 12-lead ECG), jugular venous pressure (elevated JVP = heart failure or fluid overload), palpate pulses for quality regularity and equality, (barely palpable = poor CO), Abounding pulse = sepsis, measure BP, auscultate the heart (murmur? difficult to hear = cardiac tamponade), look for evidence of bleed

Action:- insert IV, take blood for routine haematological, biochemical, coagulation and microbiological investigations, and cross-matching. Lactate level = tissue perfusion, low BP = give fluid, monitor HR and BP, if the patient is bleeding, replace blood with blood, if BP does not improve stimulate vasoconstriction

62
Q

What are the problems, assessments and actions for Disability?

A

Disability = consciousness, neurological function

Problems:- hypoxia or hypercapnoea, drugs –sedatives, opioids, toxins, poisons, cerebral hypoperfusion (e.g. from hypotension), raised intracranial pressure, CVA, metabolic dysfunction (e.g. hypoglycaemia)

Assessment:-
ABC-DEFG, check glucose, temperature, assess neurological status (rapid assessment ACVPU and formal assessment GCS), check pupils for size equality and reactivity to light, assess for pain, check drug chart

Action:- Provide glucose if needed, analgesia for pain (Specific e.g. treat seizures, treat opioid toxicity with Naloxone, seek specialist input if raised intracranial pressure)

63
Q

What are the problems, assessments and actions for Exposure?

A

Full exposure of the body may be necessary.
Respect the patient’s dignity and minimise heat loss.

Examine head to toe, front and back. Look for bleeding, swellings, rashes, sores, wounds, catheters etc. Perform focused exam of relevant systems. Take a full clinical history from the patient, any relatives or friends, and other staff. Review the patient’s notes and charts, the results of laboratory or radiological investigation

Q

What are the 4 quadrants of the abdominopelvic cavity? What organs are found in each?

A

Right upper = right of the liver, gallbladder, right kidney, a small portion of the stomach, portions of the ascending and transverse colon and small intestine

Right lower = cecum, appendix, part of the small intestines, the right female reproductive organs, and the right ureter

Left upper = left of the liver, stomach, pancreas, left kidney, spleen, parts of the transverse and descending colon and small intestine

Left lower = majority of the small intestine, some of the large intestine, the left female reproductive organs, and the left ureter

69
Q

What are the 9 regions of the abdominopelvic cavity?

A

Right hypochondriac, right lumbar, right illiac, epigastric, umbilical, hypogastric (or pubic), left hypochondriac, left lumbar, and left illiac divisions

Perineum = 10th division

70
Q

What is found each of the 9 abdominal divisions?

A 
RH = right of the liver, the gallbladder, right kidney, and parts of the small intestine
LH =  part of spleen, left kidney, part of stomach, pancreas, and parts of the colon
Epi = majority of stomach, part of the liver and pancreas and duodenum and spleen, and adrenal glands (puffs out due to diaphragm when breathing)
RL = gallbladder, left kidney, part of liver, and ascending colon
LL = descending colon, left kidney, and part of the spleen
Umb = umbilicus (navel), small intestine, part of the duodenum, the jejunum, and the illeum. Transverse colon and the bottom of the kidneys 
RI = appendix, cecum, and the right iliac fossa
LI = descending colon, the sigmoid colon, and the left illiac fossa
Hypo = bladder, part of the sigmoid colon, the anus, and organs of the reproductive system e.g. uterus and ovaries in females and prostate in males
71
Q

What are diverticula? At what age are they common?

A

Small pouches developed on the colon - more common with increasing age

72
Q

Why and how do diverticula develop?

A

Related to not eating enough fibre - harder to push out stools, increased pressure = push the inner lining of a small area of your gut through the muscle wall to form a small diverticulum

73
Q

Diverticulosis VS Diverticular Disease VS Diverticulitis?

A

Diverticulosis = diverticula are present by asymptomatic
Diverticular Disease = diverticula cause intermittent pain or bloating without swelling, cramps tend to come and go. Symptom overlap with IBS (more common in young people) or early bowel cancer
Diverticulitis = infection and inflammation of diverticula

74
Q

How does diverticulitis present?

A 
Constant pain (usually lower left side) of abdomen
Fever
Constipation / Diarrhoea
Mixed blood in stools 
Nausea / Vomiting
75
Q

What are some complications of diverticulitis?

A

Colon obstruction
Collection of pus (abscess)
Fistula (Channel) may form to other organs e.g. bladder
Perforation in the wall of the bowel - can lead to peritonitis (infection inside abdomen)

76
Q

Why may diverticula bleed? Is it painful?

A

Bleeding due to burst blood vessel in wall of diverticulum - usually abrupt, painless, blood passes via anus
Severe bleed requires intervention e.g. blood transfusion or surgery
Colonoscopy may be required to determine the cause of bleeding

77
Q

What is the treatment for diverticulosis?

A

High-fibre diet advised (18g/day advised), helps make softer and larger stools - helps prevent constipation

May prevent further diverticula forming
Healthy lifestyle = stop smoking, regular exercise, lose weight is obese

78
Q

What is the treatment for diverticula disease?

A

High fibre diet - foods including: wholegrains, fruits, vegetables, brown rice, wholewheat pasta, beans, pulses, legumes, wholewheat bread / flour
Drink lots of fluids with high-fibre diet
Paracetamol for pain
Antipasmodics e.g. Mebeverine for persistent abdominal spasms

79
Q

What is the treatment for diverticulitis?

A

Course of antibiotics and fluids via IV
Follow high fibre, lots of fluid diet
Stronger painkillers
Surgery to treat complications

Repeated diverticulitis attacks = surgery to remove that portion of the colon

80
Q

How is diverticulosis diagnosed?

A

For people without symptoms, found incidentally during evaluations for other conditions e.g. during colonoscopies etc.

81
Q

How is diverticulitis diagnosed?

A

CT scan to confirm a diagnosis of diverticulitis

CT scan is required to diagnose complications e.g. an abscess
