Q

Recall the characteristics of ARDS

A

A - Absence of raised capillary wedge pressure
R - Reduced blood oxygen (hypoxaemia)

4
Q

Explain the aetiology of ARDS

A

Severe insult to lungs
Inflammatory mediators released
Capillary permeability increases
Results in pulmonary oedema, reduced gas exchange and reduced lung compliance.
(Injury, inflammation, increased permeability)

Q

Identify appropriate investigations for ARDS

A

Bloods
Imaging = CXR to look for bilateral infiltrates
ECG - to look for mitral valve dysfunction (=valve beneath LA: dysfx –> build up of pressure in lungs)
PAC to check PCWP (pressure in left atrium)

Q

Why does alcohol withdrawal cause symptoms?

A

Body has increased sensitivity to glutamate in alcoholics so when alcohol consumption stops there are excitatory symptoms

Q

Distinguish immunogenic and non-immunogenic anaphylactic shock

A

Recall the signs of anaphylaxis

A
URTICARIA:
Urticaria
Reduced BP
Tachypnoea

Adrenaline (IM)
20
Q

Recall the pathophysiology of aspirin overdose

A
Really High Aspirin Consumption Does Harm Always
Resp centre stimulation
Hyperventilation
Alkalosis (respiratory)
Compensation by kidneys: urine bicarb and K+ increased
Dehydration
Hypokalaemia
Acidosis (metabolic)
21

OVERDOSE
Over-
Ventillation
Ears ringing
Red-faced
Dizziness
Overtired
Sweating
Epileptic-looking
22

A

Fever
Tachycardia
Hyperventillation
Epigastric tenderness

23
Q

Recall the appropriate investigations for aspirin OD

A

Bloods (including salicylate and ABG to show acidosis/alkalosis)
ECG (to look for hypokalaemia)

24
Q

Recall the 3 severities of burns injury and the approx healing time for each of these

A

Superficial - 7 days
Deep - 21 days
Full thickness - requires skin graft

25
Q

What is it important to check for in burns injury that you might forget?

A

Inhalational njury

26
Q

What investigations should be done in an electrical burn case?

A

CK
ECG
Urine myoglobin

27
Q

Which is the most commonly injured artery in extradural haemorrhage?

A

Middle meningeal artery

28
Q

Recall the characteristic progression of extradural haemorrhage

A

Temporary loss of consciousness –> lucid phase –> deterioration of GCS

29
Q

Recall the signs of extradural haemorrhage

A
Mnemonic: Sudden damage can result in haemorrhage
Scalp trauma
Deteriorating GCS
Raised
ICP
Headache
30
Q

What is indicative of extradural haemorrhage on CT?

A

Shift in midline that shows raised ICP

31
Q

Define multi-organ dysfunction syndrome

A

Affects 2 or more organ systems and is induced by variety of insults including sepsis

32
Q

How is MODS measured?

A

It is scored 1-4

33
Q

Summarise the 4 MODS scores

A

1: Mild respiratory alkalosis and hyperglycaemia
2: Hypoxia + tachypnoea, liver dysfunction
3: Acid-base disturbance, azotaemia, coagulation abnormalities (due to liver dysfunction)
4: Lactic acidosis, ischaemic colitis, vasopressor dependent

34
Q

What is the main investigation in MODS

A

ABG - need to asses where they are in the alkalosis –> acidosis spectrum
