The Impact of Preoperative Glycemic Control on Postoperative Outcomes in Diabetic Patients Undergoing Major Surgery

Diabetes mellitus (DM) is a significant risk factor for postoperative complications in patients undergoing major surgery. Preoperative glycemic control plays a crucial role in determining surgical outcomes, influencing infection rates, wound healing, cardiovascular events, and overall recovery. This review examines the impact of preoperative glycemic management on postoperative morbidity and mortality in diabetic patients. Recent evidence highlights the importance of optimizing blood glucose levels prior to surgery to reduce complications and enhance recovery. This paper discusses various strategies for glycemic control, perioperative glucose targets, and their implications for surgical outcomes.
