I have a tendency to waffle and take a long time to say things that could be said in a much shorter time period. Which is to say, I am excessively verbose. Some strategies (evolving):
Organisation
“Key Issues” as a general heading for relevant SAQ/viva questions as a means of demonstrating that I have a handle on how to approach an issue without going into unnecessary detail if time does not permit or the examiner is not interested Or “key concerns”, “key considerations”, etc Dot points with phrases rather than full sentences (avoids unnecessary words which take more time to write) For vivas especially, consider picking three considerations which are the most important/relevant for the case and therefore most likely to pick up marks Words and Phrases
Write out terms once but then specify an acronym for future use e.g. “damage control resuscitation (DCR)” Context-sensitive approaches “Obstetric and non-obstetric causes” “Structural and non-structural” (e.g. causes of decreased GCS) “Haemorrhage control: general + specific to pelvic trauma” “Decision-making” → “judgment” (e.g. “judgment about need for further imaging vs straight to OT”) “Lung protective ventilation” Specific Things to Mention
NESB → interpreter needed (nothing more to say) Specific Questions
“What is your anaesthetic plan?” “I would give a [general/spinal/etc] anaesthetic using an [ETT/other type of airway if relevant]” “The key intraoperative considerations are x, y and z” “Because of x, I would do [some things]” “Because of y, I would do [some other things]”
