腹部外科手术切口感染相关因素分析

Analysis of related factors of incision infection in abdominal surgical operation

目的：探讨腹部外科手术切口感染的危险因素，提出预防对策。方法以行腹部外科手术患者1854例为研究对象。按照是否发生手术切口感染，分为感染组76例和非感染组1778例。采用单因素分析和 Pearson 相关性分析总结腹部外科手术切口感染的危险因素。结果单因素分析结果显示：年龄、BMI、切口类别、手术时机、手术时间、合并糖尿病、放置引流管、夏季手术是腹部外科手术切口感染的危险因素（t 或χ^2＝8．925、5．840、5．376、5．445、5．846、19．674、17．436、5．700，均 P 〈0．05）。经 Pearson 相关性分析：年龄、BMI 指数、切口类别、手术时机、手术时间、合并糖尿病、放置引流管和夏季手术是腹部外科手术切口感染的危险因素（r ＝0．746、0．689、0．835、0．584、0．691、0．548、0．760、0．813，均 P 〈0．05）。结论腹部外科手术切口感染与多种因素有关。有必要对各种危险因素进行针对性的干预，降低切口感染率。

Objective To explore the abdomen surgical incision infection risk factors,and to put forward prevention countermeasures.Methods 1 854 patients with abdominal surgery were selected as subjects.According to whether had surgical incision infection,they were divided into the infection group（76 cases）and the non -infection group（1 778 cases）.Single factor analysis and Pearson correlation analysis were used to summarize abdominal surgical incision infection risk factors.Results Single factor analysis results showed that age,BMI,category of incision,operation timing,operation time,diabetes mellitus,drainage tube placement,summer were risk factors for abdominal surgery incision infection （t or χ^2 =8.925,5.840,5.376,5.445,5.846,19.674,5.846,19.674,all P 〈0.05）.Pearson correlation analysis showed that age,BMI,category of incision,operation timing,operation time,diabetes mellitus, drainage tube placement and summer surgery were risk factors for abdominal surgery incision infection （r =0.746, 0.689,0.746,0.689,0.691,0.548,0.760,0.548,all P 〈0.05）.Conclusion Abdominal surgery incision infection is associated with many factors.It is necessary for all kinds of risk factors for targeted intervention to reduce incision infection rate.
