目的探讨充气式保温毯预防老年脑肿瘤患者开颅术中低体温发生的效果。方法老年幕上脑肿瘤患者64例，随机分为观察组和对照组，各32例。观察组予(40±2)℃的充气式保温毯保温，对照组采用常规保温法，持续监测记录两组患者麻醉开始至手术结束时肛温的变化，并分析两组患者术中低体温发生情况。结果两组患者在麻醉开始时、手术开始时、及手术开始后1 h、2 h的体温，对照组体温有下降趋势，观察组的体温基本保持稳定，但两组体温没有显著性差异(>0.05)，在手术开始的第3 h起至手术结束时，对照组体温明显下降，观察组的体温较对照组体温更接近正常，两组体温有显著性差异(<0.05)。观察组2例体温<36oC，低体温发生率为6.25%；对照组8例体温<36oC，低体温发生率为25.0%，两组比较，2=4.267，0.05) .However,from the third hours of operation,The rectal temperature of observation group were higher with statistical dif erence ( <0.05) .Tthe incidence rate of hypothermia of observation group were lower than the that of control group at the same periods, which were of statistical dif erence ( 2=4.267, <0.05) . Conclusion Air-forced warming blanket can ef ectively keep the stability of body temperature during operation in elderly patients with brain tumors ,and reduce the incidence of hypothermia.
