Impact of Temperature and Humidity of Carbon Dioxide Pneumoperitoneum on Body Temperature and Peritoneal Morphology

Abstract

Insufflation with cold, dry CO2 may lower the body temperature during laparoscopic surgery. Hypothermia can be prevented by both heating and humidifying the insufflation gas. Changes of the peritoneal surface occur after CO2 insufflation, despite heating or humidifying, and also after gasless surgery.
