Abstract
PURPOSE: Perioperative hypothermia has been shown to be an important determinant of outcome after open colorectal resections. The degree of hypothermia occurring with laparoscopic-assisted colorectal surgery is, however, unknown, and the effectiveness of standard warming measures is untested. This study was designed to assess hypothermia in open and laparoscopic-assisted colonic resections using a standardized warming protocol. METHODS: A prospective, nonrandomized study was performed with temperature measurements recorded every ten minutes. Statistical analysis was based on repeated measures analysis of variance models with significance set at the conventional 95 percent (two tailed). RESULTS: A total of 107 patients were entered into the trial; 68 had open and 39 had laparoscopic colectomies. The groups were well matched for age, weight, and duration of surgery, with a median operating time of 180 minutes in each group. The average drop in temperature from commencement of surgery to lowest point was 0.68°C (standard deviation, 0.08) in the open group, compared with 0.53°C (standard deviation, 0.06) in the laparoscopic group (P=0.126). CONCLUSIONS: Laparoscopic-assisted colorectal surgery is not associated with a higher incidence of perioperative hypothermia than open colorectal surgery using a standard warming regimen for both groups. On the basis of these results, standard temperature conservation is adequate, even for long complex laparoscopic procedures.
