Abstract: PURPOSE: Laparoscopic colorectal surgery is often prolonged and may cause hypothermia. It is uncertain if heated and humidified carbon dioxide (CO(2)) in laparoscopic colorectal surgery is beneficial. This is a prospective case-matched study on the use of heated and humidified CO(2) in patients undergoing laparoscopic colorectal surgery. METHOD: Twenty consecutive patients undergoing laparoscopic colorectal surgery with heated (36 degrees C) and humidified (95%) CO(2) were compared with 20 consecutive patients using standard CO(2) (30.2 degrees C). All procedures were performed by a single surgeon in an institution. The changes in core temperature during surgery, visual quality of images and the short-term clinical outcome were documented. RESULTS: The core temperature fell during surgery in both groups. Although the fall of core temperature was more in the control group, it was not statistically significant (P > 0.05). The passage of flatus was more delayed in heated and humidified group (P = 0.004), but it did not affect the hospital discharge. All the other parameters, including the quality of visual images and the postoperative pain, were similar in both groups. CONCLUSIONS: Despite better temperature maintenance (nonsignificant), pneumoperitoneum using heated and humidified CO(2) gas did not appear to have any clinical benefits in laparoscopic colorectal surgery.
