This approach has been design ed to provide adequate analgesia while minimizing exposure to adverse events
Background : Laparoscopic cholecystectomy has advantages over the open procedure for postoperative pain .
However , a systematic review of postoperative pain management in this procedure has not been conducted .
A randomized controlled trial assessing the benefit of humidified insufflation gas during laparoscopic surgery
Abstract Background : We conducted a r and omized controlled trial during laparoscopic cholecystectomy to determine the extent of heat preservation and postoperative pain reduction using humidified carbon dioxide ( CO2 ) gas insufflation instead of st and ard dry insufflation gas . Methods : Forty consecutive patients were r and omized . Twenty patients received humidified CO2 , and 20 control patients received st and ard CO2 insufflation .  A sample of 16 patients from each group was evaluated for postoperative pain levels . Results : No adverse effects from the humidification of insufflated gas were observed . There was no significant difference in core body temperature between the two groups for this brief operation . Pain , as assessed by the Analogue Pain Score ( APS ) was significantly less for the group with humidified gas insufflation than for the control group at 6 h postoperatively as well as on the 1st , 2nd , and 3rd postoperative day and at follow-up 10 days after the operation . In the humidified group , the mean time to return to normal activities was significantly less—5.9 days , as compared to 10.9 days in the control group . Conclusions : The use of humidified insufflation gas reduces postoperative pain following laparoscopic cholecystectomy , but except for these relatively brief procedures , the heat-preserving effect of humidified gas insufflation is not significant
