Q
DCD criteria, what doesn’t include
a) Immobility
b) Apnoea
c) Absent skin perfusion
d) Absence of circulation (no arterial pulsatility for 2 min)
Cannot recall other option, which was the answer (maybe absence of sedation?)
A
Ans: d
Should be absence of pulsatility for 5 minutes not 2 minutes.
Donatelife best practice guideline:
- Arterial blood pressure monitoring is recommended
- Absence of arterial pulsatility for 5 minutes is observed prior to confirmation of death
- Electrical asystole is not required, noting that electrical (ECG) activity may persist beyond circulatory arrest
- Death is confirmed by clinical examination (e.g. absence of spontaneous movement, breathing, heart sounds and central pulse)
- Post-mortem interventions that may restart the circulation should not be undertaken e.g. mechanical ventilation, chest compression

c) Formication
d) Pruritis

Allodynia “pain due to a stimulus that does not normally evoke pain such as light touch”
17
Q
What drug to avoid in congenital long QT
a) Propofol
b) Thiopentone
c) Ketamine
A
Uptodate:
= Droperidol, haloperidol, volatile, ondansetron, amiodarone. methadone
Propofol has least effect. Prop/remi TIVA is safe
“ketamine should be avoided because of its sympathomimetic effects”
Glyco and atropine can prolong QTc and precipitate torsades.
Thiopental can be used in patients with prolonged QT (prolongs the QTc but reduces TDP - transmural dispersion of depolarization)
Long QT syndrome | BJA Education | Oxford Academic (oup.com)
18
Q
Recurrent torsades treatment, acceptable
a) Flecainide
b) Lignocaine
c) Procainamide
d) Amiodarone
e) Sotalol
A
Ans: Lignocaine (dose is 1mg/kg bolus - ANZCOR)
- Overdrive pacing - Lignocaine decreases the QTc - Beta blockers - Isoprenaline
Uptodate:
- If baseline QTc is normal then less likely to respond to Mg and IV amiodarone may prevent recurrence.
“polymorphic VT” = without QT prolongation
“torsades” = a form of polymorphic VT with QT prolongation
19
Q
- Acceptable tryptase to diagnose anaphylaxis
a) (1.2 times normal) + 2
b) (1.8 times normal) + 2

A
Ans: 2+ (1.2 x baseline)
Uptodate

“Delayed neurocognitive recovery” if present within 30 days of surgery
Delirium = 24-72 hours post op
” changes in cognition earlier than 7 days after surgery cannot be accurately tested and attributed to POCD”
“POCD can be detectable FROM 7 days after surgery”

73
74. What is the most sensitive predictor of 30 day mortality and MACE?
- DASI score 55
- AT<11
- proBNP >300
6MWT<…
I suspect the answer is a ProBNP > 300. a DASI of 55 is a good thing. Anaerobic threshold < 11 mL/kg/min was not as predictive. Hard to know what the distance was given of the 6MWT, generally cutoff of 370 m or less is bad, however it was also not as sensitive
This question is referencing the METS trial
74
75. VO2 max and DASI questionnaire relationship, score of 40 on DASI equals what?
- 20L/min or ml/kg/min
- 30
- 40
- 50
Other: DASI 48 = 48 VO2 max?
Assuming a score of 48 on DASI (if misremembered) = (0.43 * 48) + 9.6 = 30.24 Ml/kg/min
To simplify it you can make it 40/2 + 10 = 30
If divide that by 3.5 you get METS -> 8.5 METS
75
76. Drug that will not raise pulmonary vascular resistance at low doses?
- Dopamine
- Vasopressin
- Noradrenaline
- Milrinone
- Dobutamine
OR Which is most likely to cause pulmonary hypertension?
- Dopamine
- Dobutamine
- Vasopressin
- Milrinone
Prostacycline
Bit unclear this one.
I reckon that milrinone is probably the answer
But dobutamine also decreases PVR as well
Agree we think milrinone probably correct??
- Vasopressin also attenuates pulmonary hypertension
Uptodate:
Pulmonary vasoconstriction --> phenylephrine, adrenaline,
Milrinone and dobutamine inodilators. Milrinone also reduces PVR.
76
77. Sepsis guidelines, which measure is NOT recommended to assess fluid status?

Weak recommendation, very low-quality evidence
Remarks
Dynamic parameters include response to a passive leg raise or a fluid bolus, using stroke volume (SV), stroke volume variation (SVV), pulse pressure variation (PPV), or echocardiography, where available.

Use of methylene blue rather than patent blue
- Reduced rate of anaphylaxis
- More expensive
