Hyperglycemia is a common occurrence in patients undergoing cardiac surgery. Evidence suggests it is associated with increased perioperative mortality and complications. Preoperatively, HbA1c and fasting blood glucose are reliable methods for identifying patients at increased risk for both hyperglycemia and perioperative morbidity. Perioperative glycemic control by insulin therapy provides considerable benefit to cardiac surgery patients at a cellular and clinical level. Optimal target for blood glucose concentrations as well as the optimal protocol for its delivery remains controversial due to wide variability of studied populations, methodology, and outcomes. Review of available literature suggests that moderate glycemic control (100–140 mg/dL, or 140–180 mg/dL) is at least equivalent, if not superior to intensive control (80–110 mg/dL) in patients undergoing cardiac surgery, however, special populations may benefit from intensive control.
