摘要
目的探讨围术期不同时机应用主动保温策略对剖宫产患者麻醉后寒战反应发生率的影响。方法选择拟行剖宫产术患者60例,随机分为对照组(A组)、预保温组(B组)、预保温联合术中保温组(C组)和术中保温组(D组);对照组常规被动保温,其他组采用充气式保温毯进行主动保温;预保温组在麻醉前给予15 min以上的主动保温,联合保温组术前采用预保温联合麻醉后术中保温,术中保温组仅在麻醉后进行保温;记录各组患者体温变化、寒战反应发生率及寒战分级情况。结果 4组患者麻醉后核心体温均随时间降低,C组体温下降(0.39±0.26)℃,显著低于其他3组下降值(P<0.01);4组寒战发生率分别为60.0%、13.3%、6.7%和6.7%,B、C、D组与A组相比,寒战发生率显著降低(P<0.01)。结论采用主动充气式保温系统在不同时期的保温策略均可以有效降低剖宫产患者寒战发生率,且预保温联合术中保温效果最佳。
Objective To study the effect of different forced-air-warming strategies on incidence of shivering during cesarean section. Methods Sixty patients scheduled for cesarean section were randomly divided into four groups： control group （group A）, prewarming group （group B ）, combined warming group （group C ） and intraoperative warming group （group D）. In group A, conventional passive warming was applied. Active warming was applied only 15 minutes before the induction of anesthesia in group B, only during surgery in group D and both in group C. Core temperature, incidence of shivering and shivering grading status were recorded. Results Core body tempera- ture in four groups were reduced over time and there was a significant lower change in group C （0. 39 ± 0. 26 ℃ ） than the other three groups（P 〈0. 01 ）. The incidence of shivering in four groups were 60.0% , 13.3% , 6.7% , 6. 7%, and was lower in group B, group C and group D than that in control group （ P 〈 0. 01 ）. Conclusions Forced-air-warming system may effectively reduce the incidence of shivering in patients with cesarean section, and orewarming combined with intraooerative warming could most effectively reduce intraooerative hvoothermia.
