Background: The cornerstones of sepsis management continues to include early identification, early appropriate empiric antibiotics, definitive source control, and vasopressors to support end organ perfusion. There have been multiple studies looking at the co-administration of hydrocortisone, ascorbic acid, and thiamine (known as HAT therapy or the metabolic cocktail) to help reduce mortality and reverse shock. Despite the original Marik study showing an association between HAT therapy and a 31.9% overall decrease in mortality and a 3-fold decrease in time to vasopressor discontinuation in patients presenting with severe sepsis and septic shock, the mortality benefit has not been reproduced in subsequent randomized clinical trials.  Studies focused specifically on the use of corticosteroids have demonstrated reduced time on vasopressors in patients in septic shock.  The bigger question is does vitamin C and thiamine add anything additional to help improve mortality (The ORANGES Trial)?
