普通外科手术切口感染相关因素Logistic回归分析

Correlative Factors to Incision Infection in General Surgery:A Logistic Regression Analysis

目的探讨引起普通外科手术切口感染相关因素及预防。方法回顾性分析医院普通外科手术1830例患者的临床资料,将手术切口感染者作为观察组,无感染患者作为对照组,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1830例患者中有切口感染者57例,感染率3.11%;单因素分析共筛选出10个因素与切口感染有关;经过Logistic回归分析年龄大、体重指数高、手术时间长、急诊手术、合并基础疾病为切口感染的相关因素。结论结论普外科切口感染发生率较高,与多种因素有关,应针对相关危险因素预防与控制切口感染。

OBJECTIVE To discuss the related factors and the prevention of incision infection in general surgery.METHODS The data of 1830 general surgical patients were analyzed retrospectivly.The observation group consisted of patients with surgical incision infection and the control group was of Non-infected patients,and the factors that might cause incision infection were analyzed by single-factor and logistic regression.RESULTS From 1830 cases,57 cases were with incision infection.Its prevalence was 3.11%.Their were 10 factors related to the incision infection by single-factor analysis,and after logistic regression analysis,we knew that were older age,higher BMI,long surgery time,emergent surgery,and combined with underlying diseases were the related factors causing incision infection.CONCLUSIONS General surgery incision infection rate is higher deu to a variety of factors.We should target at the related risk factors to prevent and control the incision infection.
