充气温毯加热对剖宫产产妇寒战发生情况的影响

Forced-air warming for prevention of shivering in spinal anesthesia in cesarean section

目的评价充气温毯加热对剖宫产产妇寒战发生情况的影响。方法选择2014年6—12月收治的择期行剖宫产手术的产妇76例作为研究对象,随机分为对照组37例和温毯组39例。对照组产妇给予常规加温护理,温毯组产妇给予充气式温毯加热。记录并比较两组产妇入室时、麻醉后、胎儿娩出后及术毕的体温和寒战发生情况。计量资料组间比较采用t检验,组内比较采用配对t检验,计数资料采用χ2检验,P<0.05为差异有统计学意义。结果对照组产妇胎儿娩出后和术毕时体温分别为(36.3±0.12)、(36.1±0.21)℃,均低于入室时的(36.9±0.13)℃,差异均有统计学意义(均P<0.05)。温毯组胎儿娩出后和术毕的体温[(37.0±0.11)、(37.0±0.13)℃]均高于对照组,差异均有统计学意义(均P<0.05)。温毯组寒战发生率为2.56%,明显低于对照组的29.73%,差异有统计学意义(P<0.05)。结论充气温毯物理加热能够有效保持产妇体温,预防产妇寒战的发生,值得临床推广应用。

Objective To assess the impact of forced- air warming on the incidence of shivering after cesarean section. Methods76 patients scheduled for cesarean section under spinal anesthesia from June to December in 2014 were selected, randomly divided into control group（n=37） and group F（n=39）. Patients in the control groups were given routine nursing care. Patients in the group F were received forced- air warming. Body temperature and the incidence of shivering were recorded at the beginning time,after anesthesia, after delivery and at the end of the surgery. Measurement data between groups was processed by t test, in groups were processed by paired t test, count data was processed by chi square test, P〈0.05 was considered statistically significant. Results The maternal body temperatures after delivery and at the end of the surgery were（36.3±0.12） and（36.1±0.21）℃ in the control group, lower than that at the beginning time[（36.9±0.13）℃], the differences were statistically significant（all P〈0.05）. The maternal body temperatures after delivery and at the end of the surgery in group F were（37.0±0.11） and（37.0±0.13） ℃, higher than that of the control group, the differences were statistically significant（all P〈0.05）. The incidence of intraoperative shivering was 2.56% in group F, lower than that in control group（29.73%）, the difference was statistically significant（P〈0.05）. Conclusion Forced- air warming can effectively maintain the maternal body temperature and reduce the incidence of intraoperative shivering after spinal anesthesia for patients who were receiving cesarean section. It is worthy of clinical application.
