Effect of Dexmedetomidine on Postoperative Glucose and Insulin Levels.

A bolus of 1ug/kg in 10 minutes, followed by an infusion of 0.5ug/kg/h until the end of surgery.

The same infusion rate used in the dexmedetomidine group.

Intraoperative fentanyl was given in case of 25% increment in the blood pressure and/or heart rate in comparison to baseline (previous anesthesia induction).

Boluses of 3mg of intravenous morphine were given in the postoperative acute care unit. Once the pain score was equal or less than 3/10 the patient-controlled analgesia pumps were installed and the patients were discharged to their room.
