The Effect of Nutrition on Early Stress-Induced Hyperglycemia, Serum Insulin Levels, and Exogenous Insulin Administration in Critically Ill Patients With Septic Shock: A Prospective Observational Study.

Background: Stress-induced hyperglycemia is common among septic shock patients. Nutritional support influences glucose homeostasis but this effect has never been studied in septic shock. We aimed to determine the course of hyperglycemia and serum insulin levels in critically ill septic shock patients and to address the effects of caloric intake on glycemia, insulin levels, and exogenous insulin requirements.
