What is shock? A clear grasp of this concept is a MUST for any practitioner taking care of patients. Shock is many things. It is dynamic. It is elusive. It is lethal. A high index of suspicion is required to identify patients in shock. While lifesaving therapies are initiated, we must have an organized approach to to shock in order to identify the best diagnostic and therapeutic pathways for our patients. As such, we will review a simple classification system for shock. In a follow-up episode, we'll further examine the clinical presentation and management of patients presenting with hypovolemic, cardiogenic, distributive, or obstructive shock. Support the show

Join us after hours at Dr. Bryan A. Cotton's pop-up bourbon bar at the AAST 2022 Meeting in Chicago. In this FANTASTIC & FUN episode, we talk amongst friends about cutting edge research at this year's meeting. To no one's surprise, coagulopathy, damage control resuscitation, whole blood, and factor replacement therapy just happen to be but a few of the topics discussed on Rounds.
