Abstract

Background: Forced-air warming device is widely used to maintain patients’ core temperature in the intraoperative period. In recent years, disposable underbody blanket have been available in the operating room. There are few studies have targeted the warming effect of underbody blanket. We compared the heating effects between underbody blanket and overbody blanket in living kidney donors. Methods: We performed a retrospective observational study in 107 consecutive donors who underwent laparoscopic nephrectomy. We divided the donors into two groups according to the blanket types used during surgery: underbody blanket group and overbody blanket group. The following data were obtained from anesthesia records and hospital records: esophageal temperature, the time from the end of surgery to extubation, shivering and postoperative surgical site infection. Results: There were few differences in demographics and perioperative variables between the two groups. Postinduction, and lowest intraoperative temperatures were similar between the two groups. However, the temperature at the end of surgery was significantly higher in the underbody than overbody blanket group. In addition, women tended to have lower core temperatures than men in each blanket group. The time from the end of surgery to extubation was shorter in the underbody than overbody blanket group. No surgical site infections occurred. Postanesthesia shivering was slightly more frequent in the overbody than underbody blanket group, but the difference did not reach statistical significance. Conclusion: We demonstrated that the underbody blanket is superior to the overbody blanket in raising the core temperature during laparoscopic donor nephrectomy, especially in male patients.
