BACKGROUND: After laparoscopy with carbon dioxide (CO2) insufflation early postoperative recovery is often complicated with drowsiness and postoperative nausea and vomiting (PONV). METHODS:25 ASA I-II patients undergoing elective laparoscopic cholecystectomy under standardized anaesthesia were studied in a randomized, prospective study. The conventional CO2 pneumoperitoneum was compared with the mechanical abdominal wall lift (AWL) method with minimal CO2 insufflation with special reference to postoperative recovery. RESULTS:Postoperative drowsiness was of a significantly longer duration with the conventional method (p < 0.001) compared with the AWL technique. There was a positive correlation with the total amount of CO2 used and the duration of drowsiness (r = 0.75, p < 0.01). PONV was seen significantly more often in patients with CO2 insufflation of more than 121 (p < 0.05). CONCLUSIONS: Avoiding excessive CO2 is beneficial for smoother and more uneventful recovery after laparoscopic cholecystectomy.
