目的：探讨预注甲氧明对剖宫产患者腰-硬联合麻醉术中低血压的防治作用。方法收集2012年1月至2013年12月广东省东莞市清溪医院行腰-硬联合麻醉术的200例产妇资料，按随机数字表法分为研究组和对照组，每组100例。研究组患者采用预注甲氧明，对照组不预注甲氧明。比较两组各时段血压和术中低血压发生率。结果两组患者进入手术室时及手术结束时收缩压及舒张压差异无统计学意义（P＞0.05）；研究组患者腰麻5 min、腰麻10 min及腰麻15 min时收缩压及舒张压均显著高于对照组，差异均有统计学意义（均 P＜0.05）。研究组和对照组术中低血压发生率分别为4%、12%，差异有统计学意义（P＜0.05）。结论在行剖宫产腰-硬联合麻醉术时预注甲氧明能明显减少患者术中低血压的发生，对控制产妇血压有积极的作用。“,”Objective To discuss the preventive effect of pre injection methoxamine on hypotension in patients with cesarean section combined spinal epidural anesthesia.Methods The subjects of this research are the maternal with cesarean section combined spinal epidural anesthesia in our hospital,divided into study group and control group,with 100 cases in each group.The maternal in study group were given pre injection methoxamine,while control group were not given.To compare the blood pressure and incidence rate of hypotension of two groups.Results There had no statistical significance in systolic blood pressure and diastolic blood pressure when in operating room and operation end between two groups(P>0.05).While there had statistical significance in systolic blood pressure and diastolic blood pressure when spinal anesthesia 5 min,10 min,15 min(P<0.05).The incidence rate of hypotension in study group and control group were respectively 4% and 12%(P<0.05).Conclusion Pre injection methoxamine can obviously reduce the occurrence of hypotension in the maternal with cesarean section combined spinal epidural anesthesia,it has positive effect on maternal blood pressure.
