Surgical action causes a metabolic stress response that triggers an increase in cortisol levels and causes insulin resistance. The hyperglycemic state has a significant effect on increasing the morbidity and mortality of patients undergoing surgery. The purpose of this study was to determine the effect of preoperative oral glucose administration on blood glucose levels and well-being of patients in surgery under general anesthesia.
