CritCases Archives - Emergency Medicine Cases

CritCases is a collaboration between Dr. Mike Betzner, medical director of STARS air ambulance service and EM Cases. There are many approaches and therapeutic options in critical care that do not have a strong evidence base to guide us. We use our clinical judgement, gestalt and basic principles to make rapid decisions. This blog explores therapeutic options to various challenging critical care scenarios through an interactive case-based, Q&A framework. The case unfolds in a step-wise manner, as it would in real practice, and integrates opinions from critical care providers, not only from STARS, but from around the world. Each blog includes an open peer review from an expert on the given topic. Welcome to CritCases!

You are the transport physician on call. A 50-year old male with a history of depression allegedly shot himself in the chest with a rifle. A bystander called 911. The local paramedics are en route and the air transport team is activated with a plan to rendezvous at the nearest hospital, Janus General, which is 90 minutes by ground from the nearest tertiary care centre. You contact the rural hospital for a status update but all they can tell you is that his GCS is 14 and he has a GSW to the central chest.
