Emergency Medicine Flashcards
How do you measure for the size of a C-spine Collar?
From chin to where the trapezius enters the neck
Where are the major areas that bleeding can occur?
“on the floor or four more”
- external bleeding
- abdomen
- pelvis
- thorax
- long bones
Name two causes of non-trauma related pupil dilation and when should you suspect these?
Anisocoria
or
cataracts
*suspect when GCS 15
What is the ratio of blood products given?
RBCS: 4: FFP: 2: Platelets:1
List three reasons why a patient may have impaired clotting ability in trauma?
- Reduction in clotting factors due to intial clot/ loss of blood
- dilution from fluids
- Hypothermia
In major trauma why is fluids not advised, but instead just blood?
- causes haemodilution
- Sudden increase in blood pressure can dislodge the first (and best) clot
- Hypothermia - liquids are cool
Which drug should be given to all patients requiring transfusion in trauma and what rate is it given at?
Tranexamic acid 1g over 10 minutes
*must be standard within 3 hours of bleeding
List some features that would suggest someone has received burns to their airway following a fire:
Hoarseness of voice / change to voice
Soot in sputum/ around nose
Burns to face/ neck
Cough
Acute inflammatory changes to oropharynx
What are the two major complications of burns to the lungs, and how do you test for one of them?
Direct lung injury due to hot air
Carbon monoxide poisoning
*Need an ABG to detect carboxyhemoglobin
With regards to burns, what percentage of the body does the chest and abdomen take up?
how much is one leg?
and how much is the perineum?
Chest and abdomen = 18%
One leg = 18%
(Front and back)
Arm: 9%
(front and back)
Perineum = 1%
Out with the rules of 9, how else can you estimate the amount of burns someone has?
Patient palmar surface.
= 1%
so how many palm surfaces of their own palm have they burnt?
Lund and Browder chart
- used for children as more accurate
What is the fluid requirements for burns?
Anything over 2nd degree burns with >15% burns or 10% with smoke inhalation.
Parkland’s formula:
- Weight (kg) x % of burn x 4
*the first half should be given over the first 8 hours from burn. (not from presentation)
the remainder should be given over the next 16 hours.
What is the most accurate way of working out burn surface area and when is it used?
Lund and Browder
- used in paediatrics
List some causes of coma:
Coma with focal or Lateralizing
- CVA
- Trauma
- Space occupying lesion
Coma without focal or lateralizing but meningism
- meningitis
- Subarachnoid
Coma without any features:
- Toxins (including insulin)
- Endocrine (thyroid, Addison’s)
- Metabolic (Hyponatruamia, hypoglycaemia)
- Organ failure
- Seizure
Highlight the indications for an urgent CT head:
List some for CT head within 8 hours
GCS <13 GCS <15 for over 2 hours Open or depressed skull fracture or evidence of skull fracture Seizure Focal neurology >1 episode of vomiting
CT within 8 hours:
- > 65 years or older
- clotting disorders
- high impact mechanism
- > 30 mins retrograde amnesia
Falls are very common in the elderly 1/3 >65 will fall. List some key examinations that should be conducted when someone falls:
- timed up and go test
- 180 spine test
Standing/ sitting BP
Gait Examination
Proprioception and Romberg’s test
- cerebellar examination
Ocular Examination and visual acuity
PR examination
- blood loss - hypovolemia
*examine for pressure sores following a long period on the ground
List the main investigations needed for every patient that presents with collaspe and list some other that are needed:
ECG
BM
Lying/ standing blood pressure
Additional: Bloods: - FBC - U&Es - CK (long lie) - CRP - infection? - Troponin if M.I
Orifies:
- urine dip (infection)
X-rays:
- x-ray of any area damaged
- Head CT?
What are the key features of delirium?
Recent onset fluctuating awareness
Impairment of memory and attention
Disorganised thinking
What are some of the common causes of delirium along with a pneumonic?
SMASHED
S - Sepsis M - Meningitis / Mental illness A - Alcohol withdrawal S - Seizures / stimulans H - Hyper's (thyroidism, calcium) / Hypo's E - Electrolytes / Encephalopathy D - Drugs
What important aspects from the history do you want to establish in someone presenting with delerium?
When it started
Previous level of intellect
Drug/ Alcohol history
Functional status
Which patients who present with acute urinary retention should be admitted to urology?
Residual volume >1.5L
Abnormal U&Es
Frank haematuria or clots
Frial/ elderly who can’t manage their catheter
What is the act called when someone lacks capacity? If there is an emergency and treatment is needed to save the person’s life but they lack capacity then what should be done? contrast this to a non-life or death emergency:
Adults with incapacity act 2000
Life or death or prevention of significant deterioration:
- emergency treatment can be given without capacity under common law
In non - life or death a certificate of incapacity must be issued.
- they then rely on proxy to treat.
- if no proxy then the doctor in charge may make the decision
Using the adults with incapacity act 2000, If there is disagreement between the attending doctor and the proxy of the patient, what must be done?
A second medical opinion from another doctor should be sought. If they agree then treatment can go ahead.
If they disagree then the attending doctor needs submit a request to courts - in that meantime only life saving treatment can be given
Under which act are you under to report any suspicion of harm or impeding harm to an adult who is unable to safe guard themselves? and what must you do?
Adult Support and Protection Act 2007
- Contact senior
- Notify social work
