背景本研究的目的是评估使用医院毯子或BairHugger加温装置（AugustineMedicalInc.，伊甸园草原，MN），以创造一个帐篷的温暖空气。患者随机接受使用商业Bair Hugger毯子（对照组，n = 44;设定点，43 ℃）或标准医院毯子（实验组，n = 39;设定点，38 ℃）的强制空气加温。监测远端食管温度。第二天，患者进行了联系，关于任何问题与分配的温暖technology.Results：覆盖的表面积为36 +/- 12%（平均值+/- SD）在实验组和40 - 10%在对照组。两组手术结束时的最终温度相似：实验组，36.2 ± 0.6 ℃;对照组，36.4 ± 0.7 ℃。手术结束时，两组食管温度低于36 ℃的患者数量相似（实验组，39例中有12例[31%];对照组，44例中有12例[27%]）。大多数患者对其麻醉和加温技术感到满意：实验组，39例患者中的38例;对照组，44例患者中的44例。没有热损伤。结论：标准医院毛毯加热到38 degreesC强制空气是同样有效的商业毛毯加热强制空气在43 degreesC。然而，基于制造商表达的担忧，在进行进一步的安全性评价之前，不应使用该实验技术。
Background The purpose of this study was to evaluate the efficacy of an experimental approach to forced air warming using hospital blankets or a Bair Hugger warming unit (Augustine Medical Inc., Eden Prairie, MN) to create a tent of warm air.Methods: Adult patients undergoing major surgery were studied. Patients were randomized to receive forced air warming using either a commercial Bair Hugger blanket (control group, n = 44; set point, 43degreesC) or standard hospital blankets (experimental group, n = 39; set point, 38degreesC). Distal esophageal temperatures were monitored. Patients were contacted the following day regarding any problems with the assigned warming technique.Results: Surface area covered was 36 +/- 12% (mean +/- SD) in the experimental group and 40 10% in the control group. Final temperatures at the end of surgery were similar between groups: experimental, 36.2 +/- 0.6degreesC; control, 36.4 +/- 0.7degreesC. A similar number of patients had esophageal temperature less than 36degreesC at the end of surgery in both groups (experimental, 12 of 39 [31%]; control, 12 of 44 [27%]). The majority of patients were satisfied with their anesthetic and warming technique: experimental, 38 of 39 patients; control, 44 of 44 patients. There were no thermal injuries.Conclusions: Standard hospital blankets heated to 38degreesC forced air were equally as effective as commercial blankets heated with forced air at 43degreesC. However, based on concerns expressed by the manufacturer, this experimental technique should not be used until further safety evaluation has been undertaken.
