A randomised controlled trial of the electric heating pad vs forced-air warming for preventing hypothermia during laparotomy.
A randomised controlled trial was conducted to compare the efficacy of upper body forced-air warming (Bair Hugger, Augustine Medical model 500/OR, Prairie, MN) with that of an electric heating pad (Operatherm 202, KanMed, Bromma, Sweden) for maintenance of intra-operative body temperature in 60 patients undergoing laparotomy under general anaesthesia. The nasopharyngeal temperature was recorded throughout the operative period. The mean (SD) final temperatures were 36.2 (0.4) degrees C with forced-air warming and 35.5 (1.0) degrees C with electric heating pad (p < 0.01). Upper body forced-air warming is more effective than the heating pad for maintenance of body temperature during laparotomy.
