罗哌卡因加地塞米松用于关节镜术后镇痛观察

The analgesic effect of Dexameson and Ropivacaine after knee arthroscopy

目的观察和比较地塞米松和罗哌卡因配伍关节腔内注射用于膝关节镜手术后的镇痛效果。方法选择ASAⅠ～Ⅱ级择期腰麻下行单侧膝关节镜手术的患者60例,随机分为两组,每组30例。A组手术后在关节腔内注射地塞米松5mg+0.894%罗哌卡因4ml,B组手术结束后在关节腔内0.894%罗哌卡因5ml,给药后8、24、36、48h在患者双足站立,膝关节伸展状态下行视觉摸拟评分(VAS),观察两组膝关节手术后的镇痛效果。结果给药后8、24、36和48h,A组VAS评分均显著低于B组(P<0.05或P<0.01)。36h和48hVAS评分两组相比差异无统计学意义(P>0.05)。结论地塞米松加罗哌卡因用于关节腔内注射比单纯罗哌卡因关节腔内注射缓解术后疼痛的效果更好,更持久。

Objective To observe and contrast analgesic effect of Dexameson and Ropivacaine after knee arthroscopy. Methods 60 patients undergoing single side elective knee arthroscopy were assigned ran- domly into two groups （group A and group B）. In the group A, dexameson 5 mg combined with 0. 894% ropiv- acaine 4 ml were injected to intra-articular after operation with knee arthroscopy. In group B, 0. 894% ropiva- caine 5 ml were injected at the same time. Vision Analogue Score （VAS） were made in various time after oper- ation respectively. Results VAS of group A was significantly lower than that of group B in all observe time （ P 〈 0. 05）. Conclusion Intra-articular injection of Dexameson combined with Ropivacaine can not only alleviate the ache effectively after knee arthroscopy but has a longer postoperative analgesic duration.
