Viva 2

A 72-year-old male was admitted to ICU five days ago following primary resection and anastomosis of a perforated sigmoid diverticulum. He has a stable vasoactive agent requirement and is receiving empiric antibiotics. Over the last 12 hours he has produced a total of 200 mL of urine, and his creatinine has doubled from baseline to a value of 300 micromol/L.

What is your differential diagnosis for the oliguria and what is your management?

The viva focussed on the prevention and management of acute kidney injury in the critically ill.

Disclaimer: the viva stem above may be an original CICM stem, acquired from their publicly available past papers. Or, perhaps it is a slightly altered version of the original CICM stem. Or, it is a completely original viva stem, concocted by the monstrously amoral author of Deranged Physiology for nothing more than his own personal amusement. In either case, because the college do not make the main viva text or marking criteria available, almost everything here has been confabulated. It might sound like a plausible viva and it could be used for the purpose of practice, but all should be aware that it does not represent the "true" canonical CICM viva station.
