急性阑尾炎术后切口感染的相关临床因素分析

Related clinical factors of incision infection after surgery for acute appendicitis

目的回顾性分析影响急性阑尾炎术后切口感染的相关临床因素。方法选取2010年7月至2013年10月我院收治的急性阑尾炎患者479例，分为两组，其中术后切口感染者为观察组，共65例，术后切口未感染者为对照组，共414例，观察并比较两组患者手术时是否进行切口保护、病理类型、手术时间〈1h比例、病程〉24h比例。结果观察组化脓型和穿孔型比例高于对照组，手术时间〈1h比例低于对照组，病程〉24h比例高于对照组，两组病理类型、手术时间〈1h比例、病程〉24h比例比较差异有统计学意义（P〈0．05）。结论手术时未进行切口保护，手术时间长，病程久的急性阑尾炎术后容易感染，减少手术时间，手术时规范操作能有效降低术后切口感染率。

Objective To analyzed the related clinical factors of incision infection after surgery for acute appendicitis. Methods July, 2010 to October, 2013, 479 patients with acute appendicitis were selected from our hospital. 65 cases having postoperative incision infection were set as an observation group, and 414 cases without postoperative incision infecttion as a control group, whether having the cut protection, pathological type, and the proportion of surgery time 〈 1 h and 〉 24 h in both groups were observed and compared. Results The proportions of purulent type and perforation type were higher, the proportion of operation time 〈 1 h was lower, and proportion of operation time duration 〉 24 h was higher in the observation group than in the control group,with statistical differences （P 〈 0.05 ） . Conclusions Having no incision protection during operation, long operation time, and long course of acute appendicitis cause postoperative incision infection. Reducing operative time and performing surgery standardly can effectively reduce postoperative incision infection.
