The detrimental effects of hyperglycemia have been enumerated in critically ill patients, and more rigid control of glucose during the perioperative period has been advocated. The more liberal use of intraoperative continuous insulin infusions, however, has unfortunately led to an increased incidence of hypoglycemia. Anesthetized patients exhibit few, if any, signs of severe hypoglycemia. Because the brain is dependent on glucose as a primary energy source, the most devastating result of unrecognized hypoglycemia may be permanent neurologic injury or death. Therefore, it is imperative that the anesthesiologist recognize patients who are at risk for this complication and frequently measure glucose levels to avoid inadvertent hypoglycemia.
