Beneficial effects of humidified, warmed carbon dioxide insufflation during laparoscopic bariatric surgery: a randomized clinical trial.

Background: Recent data has shown that the use of warmed, humidified carbon dioxide (CO2) insufflation during laparoscopic surgery may be associated with better outcomes.

Methods: We performed a randomized, doubleblind, prospective controlled clinical trial of 30 patients undergoing laparoscopic Roux-en-Y gastric bypass (LRYGBP). Patients were randomized into 2 groups.
