摘　　要：目的探讨剖宫产术中应用右美托咪定对椎管内麻醉期间寒颤、牵拉反应的预防效果。方法入选2018年1~10月的剖宫产患者80例,随机分成对照组与观察组,各40例,两组患者在分娩中以剖宫产的方式分娩,并在胎儿剖出之后,对照组给予生理盐水进行静脉滴注,观察组应用右美托咪定静脉滴注,经过不同的干预治疗后比较两组对椎管内麻醉期间寒颤、牵拉反应的预防效果。结果观察组的寒颤发生率为12.50%,明显低于对照组的25.00%,差异有统计学意义(P<0.05)。在牵拉反应的预防中,观察组的预防优良率为90.00%,明显高于对照组的77.50%,差异有统计学意义(P<0.05)。观察组与对照组的不良反应发生率分别为7.50%与10.00%,差异无统计学意义(P>0.05)。结论剖宫产术中应用右美托咪定可以对椎管内麻醉期间寒颤、牵拉反应起到良好的预防效果,值得在临床中广泛应用。Objective To investigate the preventive effect of dexmedetomidine on chills and traction response during spinal anesthesia in cesarean section.Methods Eighty patients who received cesarean section from January to October2018 were enrolled and randomLy divided into the control group and the observation group,each had 40 cases.Cesarean section was selected as the delivery method in both groups.After the fetuses were born,the control group was given intravenous infusion of saline and the observation group was given intravenous infusion of dexmedetomidine.After different intervention treatment,the preventive effects on chills and traction response during spinal anesthesia were compared between the two groups.Results The incidence of chills in the observation group was 12.50%,which was significantly lower than the 25.00%in the control group,with statistically significant difference(P<0.05).In the prevention of traction response,the excellent and good rate of prevention in the observation group was 90.00%,which was significantly higher than the 77.50%of the control group,with statistically significant difference(P<0.05).The incidences of adverse reactions in the observation group and the control group were 7.50%and 10.00%,respectively,with no statistically significant difference(P>0.05).Conclusion The use of dexmedetomidine in cesarean section shows a good preventive effect on chills and traction response during spinal anesthesia,which is worthy of wide clinical application.
