低剂量罗哌卡因腰-硬联合麻醉用于老年患者髋关节置换术的效果及安全性

摘要

目的：分析和探讨低剂量罗哌卡因腰-硬联合麻醉用于老年患者髋关节置换术的效果及安全性。方法选择2012年12月～2014年12月在本院接受髋关节置换术治疗的老年患者80例，以40例为1组，随机分为观察组和对照组，麻醉方法对照组行单纯硬膜外麻醉，观察组行低剂量罗哌卡因腰-硬联合麻醉。观察并对比两组的应用效果。结果观察组麻黄素应用率、局麻药用量、阻滞完全所需时间分别为32.5%、（6.14±0.39） ml、（4.27±1.64）min，对照组分别为22.5%、（13.43±3.28）ml、（13.43±3.82）min，比较差异均具有统计学意义（P＜0.05）。结论在老年患者髋关节置换术中应用剂量罗哌卡因腰-硬联合麻醉会降低麻黄素应用率、局麻药用量、阻滞完全所需时间，且不会升高不良反应率，具有较高的应用效果和安全性。%Objective To analyze and discuss the effect and safety of the treatment of elderly patients with hip arthroplasty using low dose of ropivacaine combined spinal-epidural anesthesia.MethodsFrom December 2012 to December 2014 in our hospital accepted the hip arthroplasty for the treatment of 80 cases of elderly patients,in 40 cases as a group,were randomly divided into observation group and control group. Anesthesia methods in the control group was simple epidural anesthesia. Observation group used low dose of ropivacaine combined spinal epidural anesthesia. Observed and compared the effect of the two groups.Results The application rate of ephedrine,local anesthetic dosage,the time required for complete blockade of 32.5%,respectively, (6.14±0.39) ml, (4.27±1.64) min,the control group were 22.5%,(13.43±3.28) ml,(13.43±3.82) min,the differences were statistically significant(P<0.05).Conclusion In elderly patients with hip arthroplasty applied dose of ropivacaine spinal-epidural anesthesia wil reduce ephedrine application rate. The amount of local anesthetic,completely blocking the required time,and does not increase the rate of adverse reactions, with more the application of high efficacy and safety.
