Analysis of the early efficacy of intra-articular injection of ropivacaine on postoperative analgesia on the first day after total knee arthroplasty

摘要

摘要:
目的探讨全膝关节置换术后第一天关节内注射罗哌卡因对术后镇痛的早期疗效。
方法全膝关节置换术后80例病人随机分为2组。观察组：术后第一天拔除引流管后行关节内注射罗哌卡因。对照组术后第一天拔除引流管后不行关节内注射治疗。评估的内容包括术后疼痛视觉模拟评分（休息和运动状态）、手术后住院时间、术后初次下地时间、镇痛药物用量、切口并发症。
结果在休息时，术后连续5 d观察组的视觉模拟评分曲线下面积低于对照组（424±32 vs 515±39，t=11.41，P < 0.01）。术后第1天、2天观察组的各个时间点疼痛视觉模拟评分低于对照组（P < 0.05~P < 0.01）。观察组术后住院时间低于对照组，初次下地时间早于对照组（P < 0.01）。
结论全膝关节置换术后第一天关节内注射罗哌卡因可以对病人起到较好的镇痛效果，利于病人康复。

Abstract:
ObjectiveTo explore the early effect of intra-articular injection of ropivacaine on postoperative analgesia on the first day after total knee replacement.
MethodsEighty patients treated with total knee arthroplasty were randomly divided into the observation group and control group.The observation group and control group were treated with and without intra-articular injection of ropivacaine after the drainage tube was removed on the first day after operation, respectively.The postoperative pain visual simulation score(rest and exercise state), postoperative hospital stay, postoperative first time to the ground, analgesic drug dosage and incision complications were evaluated in two groups.
ResultsAt rest, the area under the visual analogue score curve in observation group for 5 consecutive days after surgery was significantly lower than that in control group(424±32 vs 515±39, P < 0.01).The visual analogue scores of pain at various time points in observation group were significantly lower than those in control group on the first and second day after operation(P < 0.05 to P < 0.01).The length of hospital stay in observation group was significantly lower than that in control group(P < 0.01).The first landing time in observation group was significantly earlier than that in control group(P < 0.01).
ConclusionsThe intra-articular injection of ropivacaine on the first day after total knee arthroplasty is a good analgesic effect on patients, and conducive to recovery.
