目的探究膝关节置换术后患者应用股神经阻滞恒速输注与自控输注镇痛的效果。方法选取2011年1月~2012年1月间人院治疗的单侧膝关节置换术患者78例，回顾性分析其临床资料，将应用自控输注法（39例）的患者设为实验组，应用恒速输注法（39例）的设为对照组。观察并计较两组患者在静息状态下、主动功能锻炼、被动功能锻炼的疼痛评分情况，并分析两组患者的不良反应发生情况。结果两组患者在静息状态、主动功能锻炼的VAS评分差异无统计学意义；但在各个时段，实验组患者在被动功能锻炼中的VAS评分均小于对照组，差异具有统计学意义。两组患者的不良反应均较少。结论膝关节置换术后股神经阻滞镇痛给药方式中。自控输注比恒速输注的镇痛效果更为理想。

英文摘要：

Objective To research analgesic effect of patients applied continuous femoral nerve to block constant infusion and automatic infusion after total knee arthroplasty operation. Methods A total of 78 unilateral knee arthroplasty patients were accepted by our hospital from January 2011 to January 2012, and were selected as the research subjects, and their clinical information were retrospectively analyzed. They were divided equaUy and randomly into experimental group and control group. Experimental group applied automatic infusion method, control group applied constant infusion. Then to observe and figure pain scoring of patients in two groups under the condition of rest state, active functional exercise and passive functional exercise, and to analyze adverse reactions of patients in two groups. Results There was no difference between two active functional exercise. While in various periods, the groups about patients＇ VAS scoring of resting state and VAS scoring of experimental group＇s patients in passive functional exercise was less than that of control group. The result has a statistical significance. Conclusion In the administration method of continuous femoral nerve blocking analgesia after total knee arthroplasty operation, the analgesic effect of automatic infusion is more ideal than that of constant infusion＇ s.
