急性阑尾炎术后切口感染危险因素的Logistic回归分析

The Logistic Regression Analysis of Acute Appendicitis Risk Factors for Postoperative Wound Infection

目的探讨引起急性阑尾炎术后切口感染相关因素及预防。方法回顾性105例腹部手术切口患者和按1∶2比例随机选择的无感染的210例患者的临床资料,对可能影响切口感染的因素资料进行单因素分析与Logistic回归分析。结果单因素分析共筛选出15个因素与切口感染有关;经过Logistic回归分析探查切口、皮下脂肪≥2cm、合并基础疾病、手术时间长、阑尾化脓坏疽穿孔切口感染的危险因素。结论急性阑尾炎术后切口感染是多因素综合作用的结果,应针对上述因素预防和控制切口感染。

Objective To explore the cause of postoperative wound infection in acute appendicitis-related factors and prevention. Method Retrospectively 105 cases of abdominal surgery patients and the ratio of 1 ： 2 by random selection of 210 cases of non-infected patients with clinical data, which may affect the factors of wound infection data from single-factor analysis and Logistic regression analysis. Results Single-factor analysis of a total of 15 factors were selected with the incision infection; Logistic regression analysis after exploratory incision, subcutaneous fat ≥ 2cm, the combined basis of disease, surgery for a long time, perforated gangrenous appendix suppurative wound infection risk factors. Conclusion Postoperative wound infection in acute appendicitis is a multi-factors, these factors should be targeted at the prevention and control of infection of incisional wound.
