ANZCA Part 1 SAQs

My personal collection of my model answers for a bunch of SAQs for the ANZCA part one exam. Only recorded after I’ve managed to write an 8-10 min answer rather than including long explanations. Derived from various textbooks and model answers (propofol dreams, ketamine nightmares, adrenaline memories). This is not medical advice for individuals, nor is it clinical advice for healthcare professionals.

Episodes

Tissue demand for O2 and cardiac output

Adrenaline memories answer very good. I changed some of the headings to simplify it with how I understand it. The key is understanding the difference in venodilation and vasodilation.

Ultrasound

A hard one to do in 10 mins but thankfully examiners report says Doppler and CO measurement are “extra marks” rather than pass marks.

Skin antiseptic agents

Povidine iodine and alcoholic chlorhexidine. This is a 2-3/5 answer. Apart from knowing that I shouldn’t inject chlorhex into someone’s spinal cord I’m not sure how this makes me a better anaesthetist.

500ml of 20% mannitol: CNS/CVS/renal effects

This is a good starting point and probably a pass as per examiners reports, but if you get time then add more detail (e.g. baroreceptor reflexes to volume changes, CVS effects of potential hyperkalaemia)

Jul 12, 2022•2 min

Blood brain barrier

Na+ transport passive as per Power and Kam. Doesn’t make sense to me but it’s a recommended text so going to run with it 👍🏽

Right lateral position ventilation and perfusion

Graph from ketamine nightmares is elite for understanding but not sure I would have time to draw three graphs. Could do the full table for VQ at dead space/apex/ideal alveolar gas/base/shunt with O2 and CO2 values if you get time.

Jul 09, 2022•3 min

ROTEM physiology and hyperfibrinolysis

Graph very important. TEG probably simpler but I chose ROTEM because it’s what they actually use at work and this exam is all about becoming a better anaesthetist!

Jul 07, 2022•2 min

Hypothalamus

At the start I think it’s worth putting abbreviations to denote A for anterior, P for posterior, M for medial, L for lateral

O2 and CO2 Hb dissociation curves

Look up a diagram. Best one I could find was Ketamine Nightmares (had both on same axes and content rather than saturation %). Also correction that bicarbonate carriage is by combination with water via carbonic anhydrase, not by “combination with bicarbonate”.

Physiological effects of 2L CSL

Minor error where I said Cl content increases the strong ion difference but actually it decreases it… my bad (Stewart approach 🤦‍♂️). But still the point stands that it causes a minor hyperchloraemic acidosis with the alkalosis of H+ being consumed by cori cycle for metabolism of lactate as the dominant process from CSL infusion.

PK for onset and offset of local anaesthetics

An annoyingly broad question that asked for the onset and offset, also didn’t specify topical or subcutaneous or nerve block. A narrower scope would make for an easier question.

Morbid obesity washout of inhalational anaesthesia

Numbers for equilibration of compartments refer to 3 time constants (not half lives) and are from Hemmings and Egan. Sevo 2 min FRC, 9 min VRG, 7 hrs MG, 5 days FG. Des 2 min FRC, 8 min VRG, 5 hrs MG, 3 days FG.

Safety features of vaporisers

Everyone use TIVA so that this is out of the syllabus ASAP or at least only given as much importance as knowing that ether has a BGPC of 12
