In this study, we propose to determine whether improved glycemic control using intensive insulin treatment immediately postoperatively will improve outcomes in patients undergoing liver transplant using a prospective, controlled, randomized, parallel-group study design targeting two different glucose levels, 140 and 180 mg/dL. Postoperative glucose management with insulin will be supervised by the Glucose Management Service as is routine, with the only research aspect being the two different glucose targets and the outcome analysis with liver transplant rejection as the primary outcome and infections and hypoglycemia being the principle secondary outcomes.
