Management of blood glucose is important in avoiding central nervous system dysfunction. Although no single regimen works for all patients, in general, insulin-dependent patients should undergo surgery early in the day whenever possible to minimize disruption of their metabolic status, and their glucose levels should be monitored postoperatively. For a diet-controlled diabetic patient undergoing a brief surgical procedure, management generally involves only monitoring of the blood glucose level immediately after surgery and every 3 hours until oral intake is resumed. It is imperative to provide close perioperative monitoring of glucose and electrolyte levels.
