麻醉诱导期不同预保温措施对胆道闭锁患儿术中体温的影响

Effect of different prewarming methods during induction of anesthesia in the infants receiving Roux-Y hepaticojejunostomy

目的探讨麻醉诱导期预保温对胆道闭锁患儿术中体温的影响。方法将46例行肝门空肠Roux-Y吻合手术的胆道闭锁患儿,随机分为试验组(n=23)和对照组(n=23)。试验组患儿麻醉诱导期使用充气保温毯进行预保温30min;对照组患儿麻醉诱导期采用普通盖被覆盖保温30min。观察并记录两组患儿的体温变化情况。结果试验组术中低体温发生率为47.6%(10/21),2例因术中出血较多被剔除;对照组术中低体温发生率为78.3%(18/23)。对照组术中低体温的发生率高于试验组,两组比较差异有统计学意义(P<0.05)。结论胆道闭锁患儿麻醉诱导期应用充气保温毯预保温,有助于保持患儿术中体温相对稳定。

Objective To evaluate the effect of different prewarming methods during induction of anesthesia in the infants receiving Roux-Y hepaticojejunostomy. Methods Forty-four infants with biliary atresia receiving Roux-Y hepatieojejunostomy were randomly divided into experimental group（n=21 ）and control group（n=23）. The infants in the experimental group were prewarmed for 30 minutes by air-forced warming blanket during induction of anesthesia,while the infants in the control group were covered by traditional blanket. The core tempratures were recorded continually. Results The incidence of intraoperative hypothermia was significantly lower in the experimental group than that in the control group（47.6 percent vs. 78.3 percent, P〈0.05）. Conclusion Prewarming by air-forced warming blanket during induction of anesthesia in the infants with biliary atresia can maintain intraoperative core temperature relatively stable .
