摘要
目的研究全膝关节置换术后关节周围注射罗哌卡因结合PCA泵的镇痛效果。方法选取择期行全膝关节置换手术患者90例,随机分为3组,每组30例(n=30),第一组(A组)术后包括膝关节后关节囊和前侧切口周围组织浸润注射罗哌卡因,结合静脉PCA泵镇痛;第二组(B组)术后仅在前侧切口周围组织浸润注射罗哌卡因,而不注射后关节囊,结合静脉PCA泵镇痛。第三组(C组)术后仅采用静脉PCA泵镇痛。分别在术后2、12、24、48、72小时,以视觉模拟量表(visual analogue scale,VAS)评估患者术后的疼痛水平。结果术后2、12、24、48、72小时A、B、C组评分分别为2.0,2.1,4.9;2.7,2.6,5.5;3.5,3.4,4.6;2.4,2.5,3.8;1.4,1.4,2.8。A组和B组评分差异无统计学意义(>0.05),A组和B组评分较C组差异有统计学意义(<0.05)。结论全膝关节置换术后应用罗哌卡因和静脉PCA泵能够有效缓解疼痛,后关节囊可不注射,镇痛效果优于单用PCA泵。
Objective To observe the analgesic effects of postoperative periarticular injection and PCA pump after total knee arthroplasty. Methods 90 patients were randomize to three groups. The patients in group A （n=30） receive periarticular injection and Venous PCA pump include the posterior capsule. The patients in group B （n=30） receive periarticular injection and Venous PCA pump exclude the posterior capsule. The patients in group C （n=30） receive Venous PCA pump only. Analgesic efficiency was evaluated by visual analogue scale （VAS） 2,8,24,48,72 hours after the Operation. Results There was no statistical difference in VAS among group A and group B. VAS were lower in the groups A and B than in group C （P〈0.05）. Conclusion After 2,12,24,48,72 hours of A, B, C group was respectively 2.0,2.1,4,9; 2.7,2.6,5.5; 3.5,3.4,4.6; 2.4,2.5,3.8; 1.4,1.4,2.8. Postoperative periarticular injection and PCA pump may provide postoperative analgesia effectively. It can provide superior postoperative analgesia vesus PCA pump.
