We conducted a randomised controlled trial to compare the efficacy of forced-air warming (Bair Hugger(trade mark), Augustine Medical model 500/OR, Prairie, MN) with that of an electric heating pad (Operatherm 202, KanMed, Sweden) for maintenance of intra-operative body temperature in 60 patients undergoing total knee replacement under combined spinal-epidural anaesthesia. Intra-operative tympanic and rectal temperatures and verbal analogue score for thermal comfort were recorded. There were no differences in any measurements between the two groups, with mean (SD) final rectal temperatures of 36.8 (0.4) degrees C with forced-air warming and 36.9 (0.4) degrees C with the electric pad. The heating pad is as effective as forced-air warming for maintenance of intra-operative body temperature.
我们进行了一项随机对照试验,比较强制空气加温(Bair Hugger(商标),奥古斯汀医疗500/OR型号,明尼苏达州普雷里)与电加热垫(Operatherm 202,瑞典KanMed)对60例在腰麻-硬膜外联合麻醉下行全膝关节置换术患者术中体温维持的效果。记录术中鼓膜温度、直肠温度以及热舒适度的视觉模拟评分。两组之间的任何测量指标均无差异,强制空气加温组的平均(标准差)最终直肠温度为36.8(0.4)摄氏度,电加热垫组为36.9(0.4)摄氏度。电加热垫在维持术中体温方面与强制空气加温同样有效。
