摘　　要：目的研究剖宫产产妇腰硬联合麻醉过程中使用右美托咪定对预防术中寒战与牵拉反应的临床效果。方法随机选取2022年1月—2023年3月福建省妇幼保健院接受剖宫产手术的90例产妇为研究对象。根据随机抽签原则平均分为两组,包括对照组(45例)和观察组(45例),两组产妇均实施腰硬联合麻醉,对照组在麻醉成功后使用生理盐水;观察组在麻醉成功后使用右美托咪定,将实施效果进行比较与分析。结果观察组术中寒战发生率为2.22%低于对照组的17.78%,差异有统计学意义(χ^(2)=4.444,P<0.05);观察组牵拉反应发生率为6.67%低于对照组的22.22%,差异有统计学意义(χ^(2)=4.405,P<0.05);不同阶段血流动力学指标比较结果显示,观察组T1、T2、T结果与T0阶段比较,差异无统计学意义(P>0.05);对照组T1、T2、T3测定结果与T0阶段比较,差异有统计学意义(P<0.05);两组在T0、T1阶段的平均动脉压、心率比较,差异无统计学意义(P>0.05);在T2、T3阶段观察组平均动脉压、心率测定结果均优于对照组,差异有统计学意义(P<0.05)。结论右美托咪定的应用,有助于降低腰硬联合麻醉剖宫产产妇术中寒战与牵拉反应发生率,同时可让产妇血流动力学指标维持在稳定状态,保证更好的麻醉效果。Objective To study the clinical effect of dexmedetomidine on the prevention of intraoperative chills and pulling reactions during combined spinal and epidural anesthesia for women undergoing cesarean delivery.Methods A total of 90 parturients who received cesarean section in Fujian Maternal and Child Health Hospital from January 2022 to March 2023 were randomly selected as the study objects.According to the principle of random drawing,they were divided into two groups,including(45 cases)the control group and(45 cases)the observation group.Both groups were given combined epidural anesthesia,and the control group was given normal saline after successful anesthesia.Observation group was given dexmedetomidine after successful anesthesia,and the effect was compared and analyzed.Results The incidence of intraoperative shivering in observation group was 2.22%,which was lower than that in control group 17.78%,and the difference was statistically significant(χ^(2)=4.444,P<0.05).The incidence of stretch reaction in observation group was 6.67%,which was lower than that in control group 22.22%,and the difference was statistically significant(χ^(2)=4.405,P<0.05).The results of hemodynamic indexes at different stages showed that the results of T1,T2 and T3 in the observation group were compared with those at T0 stage,and the difference was not statistically significant(P>0.05).The results of T1,T2 and T3 in control group were compared with those in T0 stage,and the difference was statistically significant(P<0.05).There was no statistically significant difference in mean arterial pressure and heart rate between the two groups at the T0 and T1 stages(P>0.05).At the T2 and T3 stages,the mean arterial pressure and heart rate of the observation group were beffer than those of the control group,and the differences were statistically significant(P<0.05).Conclusion The application of dexmedetomidine can help to reduce the incidence of intraoperative chills and pulling reactions in cesarean delivery women under combined spinal and ep
