In this episode, we discuss the role of hydrocortisone, ascorbic acid (Vitamin C) and thiamine (HAT therapy) in the treatment of patients with septic shock. We discuss biological plausibility and comprehensively review the latest evidence. Our guest is Dr. Jonathan Charnin. Dr. Charnin is an assistant professor of anesthesiology in the Divisions of Multi-specialty Anesthesia and Critical Care Medicine at the Mayo Clinic Connect with us @DepthAnesthesia on Twitter or email us at [email protected].
