We studied 150 patients undergoing elective colonic surgery; they were allocated randomly to undergo artificial ventilation with either air-oxygen or nitrous oxide-oxygen during surgery. Eleven patients were excluded. Preoperative management, surgery and postoperative analgesia were similar in both groups. ⋯ The air-oxygen group required a continuous infusion of propofol of 4-6 mg kg-1 h-1 whereas the nitrous oxide-oxygen group required only 1-2 mg kg-1 h-1. There were no differences between the groups in duration of anaesthesia, distension of the bowel and postoperative bowel function. The postoperative hospital stay was similar for both groups.

AbstractWe studied 150 patients undergoing elective colonic surgery; they were allocated randomly to undergo artificial ventilation with either air-oxygen or nitrous oxide-oxygen during surgery. Eleven patients were excluded. Preoperative management, surgery and postoperative analgesia were similar in both groups. Anaesthesia included propofol by infusion, pancuronium and fentanyl 3 micrograms kg-1 h-1. The air-oxygen group required a continuous infusion of propofol of 4-6 mg kg-1 h-1 whereas the nitrous oxide-oxygen group required only 1-2 mg kg-1 h-1. There were no differences between the groups in duration of anaesthesia, distension of the bowel and postoperative bowel function. The postoperative hospital stay was similar for both groups.
