【目的】对比复方利多卡因软膏和利多卡因注射液用于婴幼儿先天性马蹄内翻足经皮跟腱切断术的镇痛效果，并评估两组的不良反应、手术时间和出血量的差异。【方法】将80例婴幼儿先天性马蹄内翻足需行经皮跟腱切断术的病例随机分为利多卡因注射液组（A组）和复方利多卡因软膏组（B组），各40例。A组采用利多卡因注射液局部浸润麻醉。B组采用复方利多卡因乳膏外涂局部麻醉。记录两组手术时、术后30 min、1 h、2 h、4 h、8 h、12 h、24 h的 FLACC疼痛评分、手术时间、手术出血量和不良反应并做统计分析。【结果】手术后两组的FLACC疼痛评分逐渐下降。两组手术时、术后30 min、1 h、2 h的FLACC疼痛评分相比，差异有统计学意义（ P ＜0．05）。复方利多卡因软膏组的FLACC疼痛评分低于利多卡因注射液组。复方利多卡因软膏组的手术时间和出血量低于利多卡因注射液组（ P ＜0．05）。无一例出现皮肤局部红肿、水泡等药物不良反应。无一例出现血管神经损伤。【结论】对于先天性马蹄内翻足患儿，采用复方利多卡因乳膏局麻行经皮跟腱切断术，能达到良好的麻醉效果，减轻患儿疼痛，方便术者操作，减少手术时间和出血，无明显不良反应。“,”Objective]To compare the analgesic effects of lidocaine hydrochloride injection versus com‐pound lidocaine cream in infants with clubfoot undergoing percutaneous achilles tenotomy and evaluate the side effects ,operative duration and bleeding volume .[Methods]A total of 80 patients undergoing percutaneous a‐chilles tenotomy were randomly allocated into two groups of lidocaine hydrochloride injection (A) and com‐pound lidocaine cream (B) ( n=40 each) .Local infiltration anesthesia of lidocaine hydrochloride injection was administered to group A prior to tenotomy while compound lidocaine cream applied to group B for local anes‐thesia .And the FLACC score ,side effects ,operative duration and bleeding volume was recorded and ana‐lyzed .[Results]The postoperative FLACC scores decreased gradually in both groups .And there were signifi‐cant differences during surgery ,30 min ,1 h ,2 h post‐operation ( P<0 .05) .The FLACC scores were signif‐icantly lower in group B than those in group A .There was no onset of edema ,vesicle or vascular/nerve injury . And operative duration and bleeding volume were significantly lower in group B than those in group A ( P<0 . 05) .[Conclusion]For clubfoot patients undergoing percutaneous achilles tenotomy ,the application of com‐pound lidocaine cream may achieve excellent anesthetic effects ,diminish pains ,facilitate surgical procedures , shorten operative duration and lower bleeding volume .And there is no obvious side effect .
