目的 探讨围手术期超前平衡镇痛在肛肠手术中止痛的临床效果。方法 回顾性分析2009年11月至2010年10月期间巴中市中医院肛肠科123例采用腰俞穴麻醉的肛肠手术患者的临床资料，患者被分成超前平衡镇痛组（60例）和传统镇痛组（63例）2组。2组术前准备相同，术后均口服布洛芬缓释胶囊300mg止痛，2次/d。对Ⅲ～Ⅳ度内痔及内括约肌痉挛的患者术中均常规行内括约肌松解术，对VAS评分6分以上的患者选择使用盐酸曲马多注射止痛。超前平衡镇痛组术前0.5h肌注安定10mg，口服布洛芬缓释胶囊300mg，术中采用2%盐酸利多卡因5ml、0.75%盐酸布比卡因5ml、芬太尼50 μg、地塞米松5mg用生理盐水稀释成20ml行腰俞穴麻醉并止痛，术毕肛内塞用双氯芬酸钠栓1枚。传统镇痛组术中采用2%盐酸利多卡因5ml、0.75%盐酸布比卡因5ml用生理盐水稀释成20ml行腰俞穴麻醉。比较2组术后4、6、8、12、24及48 h VAS评分、盐酸曲马多使用率及恶心、呕吐及尿潴留的发生率。结果 术后4、6、8、12、24及48 h VAS评分超前平衡镇痛组均明显低于传统镇痛组（P＜0.01），术后盐酸曲马多使用率超前平衡镇痛组明显低于传统镇痛组（P＜0.05），恶心、呕吐及尿潴留的发生率2组比较差异均无统计学意义（P＞0.05）。结论 围手术期超前平衡镇痛用于肛肠手术止痛是一种疗效肯定、安全、不良反应少而又简单易行的镇痛方法。
ObjectiveTo investigate the clinical effect and the incidence of postoperative complications of Milligan-Morgan hemorrhoids combined with reducing tension of alary incision in the treatment of annular mixed hemorrhoids.MethodsProspectively collected 120 patients with annular mixed hemorrhoids who received treatment from the Department of Colorectal Surgery of Bazhong Hospital of Traditional Chinese Medicinel during the April, 2016 to October, 2018. All of the 120 patients with annular mixed hemorrhoids were randomly divided into the experimental group and the control group, with 60 patients in each one group. Patients in the experimental group was treated with Milligan-Morgan hemorrhoids combined with reducing tension of alary incision, while patients in the control group with conventional Milligan-Morgan hemorrhoid.ResultsIn the experimental group, 49 cases were cured, 11 cases showed obvious effect; in the control group, 39 cases were cured, 20 cases showed obvious effect, and 1 case was effective. The curative effect in experimental groups was better than that of the control group (Z=–2.090, P=0.037), and the effective rates of these two group were both 100% in total. The mean healing time was (19±3) d (14–21 d) in the experimental group and (21±3) d (14–24 d) in the control group, respectively, which was better in the experimental group (Z=–13.636, P<0.001). Experimental group with lower score of wound pain, hemafecia, and anal margin edema, which were much better than control group on 1 d and 3 d after operation (P<0.05). There was no statistically significant differences on incidence of uroschesis and recurrence rate between the two groups (P>0.05).ConclusionsMilligan-Morgan hemorrhoids combined with reducing tension of alary incision in the treatment of annular mixed hemorrhoids has good clinical effect and deserves clinical application.
