Clinical Research Of Continuous Femoral Nerve Block For Analgesia And Early Rehabilitation After Total Knee Arthroplasty

Objective: To observe and discuss method and value of earlyrehabilitation training after continuous femoral nerve block.Methods:30cases of total knee arthroplasty which are carried out by thesame doctor of our hospital are selected. These patients are randomly dividedinto two groups. Continuous femoral nerve block, patient controlledintravenous analgesia (PCA) postoperative analgesia and early rehabilitationtraining are given respectively, each group of15cases. Visual analog pain scoremethod (VAS) and largest angle of knee flexion are assessed.Results: All the pain score were significantly lower in the continuousfemoral nerve block group. Within the first postoperative day, the second dayand postoperative6weeks, range of motion were significantly improved.Obvious quadriceps femoris muscle abate, incision dehiscence and infection,and deep vein thrombosis were not observed. Conclusion:1. Continuous femoral nerve block has many effects, for example, it canprovide superior analgesic effect, it has less adverse reaction, and it can indwellfor a long time, etc.2. It has little influence on muscle strength, more favorable forrehabilitation of knee joint function.
