Randomized Controlled Trial Clinical Trial
Humidified gas prevents hypothermia induced by laparoscopic insufflation: a randomized controlled study in a pig model.
This experimental study evaluated whether humidification of warmed insufflated CO2 during laparoscopic procedures would resolve the problem of laparoscopy-induced hypothermia. ⋯ The majority of heat lost during laparoscopic insufflation is due to water evaporation, and laparoscopic hypothermia may be prevented by using heated and humidified gas insufflation.

Randomized Controlled Trial Clinical Trial
A randomized controlled trial assessing the benefit of humidified insufflation gas during laparoscopic surgery.
We conducted a randomized 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 standard dry insufflation gas. ⋯ 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.
