Warmed, Humidified Carbon Dioxide Insufflation vs Standard Carbon Dioxide in Laparoscopic Cholecystectomy

Warmed, Humidified Carbon Dioxide Insufflation vs Standard Carbon Dioxide in Laparoscopic Cholecystectomy: a Double-blinded Randomized Controlled Trial

The purpose of this study is to determine the effect of warmed, humidified carbon dioxide Insufflation vs standard carbon dioxide in laparoscopic cholecystectomy.

Patients undergoing warmed, humidified carbon dioxide (CO2) insufflation for laparoscopic cholecystectomy will have less postoperative pain than patients undergoing laparoscopic cholecystectomy with standard CO2 insufflation. The study design is a double-blind, prospective, randomized study comparing patients undergoing laparoscopic cholecystectomy with standard CO2 insufflation vs those receiving warmed, humidified CO2. Main variables included postoperative pain (rated with a visual analog scales) and analgesic requirements.

Inclusion Criteria:

• Clinical diagnosis of cholecystolithiasis

Exclusion Criteria:

• Clinical diagnosis of cholecystolithiasis with cholecystitis
