摘要 目的探讨使用静脉自控镇痛泵(PCIA)的同期双膝人工关节置换术中关节腔周围注射混合镇痛药物的临床疗效。方法将32例患者一侧膝关节随机分成注射组,另一侧为对照组。注射组术中关节周围注射混合镇痛药物,而对照组不注射。术后患者给予PCIA。术后采用视觉类比评分法(VAS)评估术后两组静息痛及运动痛,注射组及对照组膝关节活动度情况。记录患者术后并发症及切口愈合情况。结果两组静息痛VAS评分术后2h(P=0.10)、24h(P=0.28)、36h(P=0.29)评分差异无统计学意义,术后6h、8h、12h两组差异有统计学意义(均P=0.00)。注射组在术后6h(P=0.00)、12h(P=0.00)、24h(P=0.01)运动痛VAS评分均低于对照组,差异有统计学意义。术后36h两组差异无统计学意义(P=0.21)。两组膝关节术前活动度差异无统计学意义(P=0.718),术后第1天两组膝关节活动度差异有统计学意义(P=0.00),而术后第5天两组膝关节活动度差异无统计学意义(P=0.316)。术后患者未观察到罗哌卡因局部注射相关的毒副作用。两组切口均为甲级愈合,均无切口感染。结论关节腔周围注射混合镇痛药物可以明显缓解使用PCIA的同期双膝人工关节置换患者的术后短期疼痛,提高术后早期关节活动度,无明显副作用。
