【摘要】 目的：分析急诊外科创伤患者术后手术切口感染风险因素及预防策略。方法：纳入2017年4月-2019年4月接诊收治的300例外科创伤手术患者，根据术后是否发生切口感染进行分组，试验组为发生切口感染的138例患者，对照组为未发生切口感染的162例患者，logistic回归分析切口感染的危险因素。结果：单因素分析中试验组与对照组在年龄、体重指数(BMI)、创伤分数(TS)以及手术时间方面比较，差异有统计学意义(P<0.05)。logistic分析示年龄≥60岁、BMI>24 kg/m2、TS评分≤4分、手术时间≥3 h是切口感染的危险因素，差异有统计学意义(P<0.05)。结论：急诊外科创伤手术患者术后切口感染与年龄、BMI、TS以及手术时间有着极为密切的联系，应当引起临床重视。

    [Abstract] Objective： To analyze the risk factors and preventive strategies of surgical incision infection in patients with emergency surgical trauma. Method： The 300 surgical trauma patients admitted from April 2017 to April 2019 were grouped according to whether incision infection occurred after surgery. The experimental group of 138 patients with incision infection and the control group was without incision infection of 162 patients. The risk factors of incision infection were analyzed by logistic regression. Result： Univariate analysis： the differences between the experimental group and the control group in terms of age ......
