目的研究腹部手术切口感染的危险因素与切口感染的关系,以期预防和控制切口感染的发生。方法收集1847例普外科腹部手术患者的临床资料,分析腹部手术切口感染的可能危险因素,并对其进行单因素分析与logistic回归分析。结果 1847例患者中发生腹部切口感染81例,切口感染率4.39%;≥60岁年龄组的598例患者有37例发生切口感染,感染率为6.19%,明显高于<60岁和<30岁年龄组的感染率3.62%和3.39%(P<0.05);手术时间>2h患者有62例感染,感染率为5.36%,明显高于手术时间在<2h患者的感染率2.75%(P<0.01);合并基础疾病患者有49例感染,感染率为5.63%,高于无基础疾病患者的3.28%(P<0.05);Ⅲ类切口的感染例数为40例,感染率为6.53%,明显高于Ⅱ、Ⅰ类切口的3.95%和2.22%(P<0.01);夏季患者的感染率为6.64%,高于其他3个季节的感染率3.82%、3.63%和3.10%(P<0.05),单因素分析切口感染与年龄、手术时间、合并基础疾病、手术季节、手术切口类型有相关性,logistic多因素回归分析发现年龄、合并基础疾病、手术时间和手术切口类型是切口感染发生的独立危险因素。结论普外科切口感染是多种因素共同作用的结果,其发生率较高,为预防控制其发生率,应当根据切口感染发生的危险因素采取相应的干预措施。
OBJECTIVE To study the relationship between the risk factors for the abdominal surgical incision infections and the incidence of the incision infections so as to prevent and control the incision infections. METHODS The clinical data of 1874 patients with abdominal surgical wound were analyzed, and the univariate analysis and logistic regression analysis of the risk factors for the surgical incision infections were performed. RESULTS Of 1847 patients investigated, there were 81 cases with incision infections with the prevalence of 4.39%, there were 37 cases with incision infections among 598 patients aged more than 60 years with the prevalence of 6.19%, significantly higher than that of the patients aged less than 60 years （3. 62%）and the patients aged less than 30 years （3.39%）. There were 62 cases with incision infections among the patients with the operation duration more than 2 hours, and its prevalence was 5.36%, significantly higher than 2.75% of the patients with the operation duration less than 2 hours （P〈0.01）. There were 49 cases with incision infections among the patients with underlying diseases, and its prevalence was 5.63%, higher than 3.28% of the patients without underlying diseases. There were 40 cases with incision infections among the patients undergoing the type Ⅲ incision surgery, and its prevalence was 6. 53%, significantly higher than 3. 95% of the type Ⅱ incision surgery and 2.22% of the type Ⅰ incision surgery（P〈0. 01）. The infection rate of the patients was 6.64% in summer, higher than 3.82 %, 3.63%, and 3.10% of the other three seasons（P〈0.05）. The univariate analysis indicated that the incidence of incision infections was related to the age, operation duration, underlying disease, season for operation, and the type of incision surgery, while the logistic regression analysis showed that the age, underlying disease, operation duration and the type of incision surgery were the independent risk factors associated with the incision infections. CONCLUSION There are many risk factors for the incision infections in the general surgery department, the incidence rate is so high that it is necessary to take the corresponding interventions according to the risk factors so as to prevent and control the incision infections.
