ANZCA Part 1 SAQs
Vibhushan Manchanda
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.
