【摘要】：目的探讨普外科术后感染的危险因素,并根据相关因素总结应对策略,以降低感染率。方法选取2012年6月-2015年6月1 200例普外科手术患者做回顾性分析,并对术后感染率、具体感染部位分布、主要病原菌分布进行单因素和多元logistic回归分析。结果在1 200例患者中,共出现感染71例,感染率为5.9%;感染部位处于前3位的分别是下呼吸道、泌尿系统以及上呼吸道。共检出病原体96株,其中,革兰阳性菌33株,占34.4%;革兰阴性菌62株,占64.6%;真菌1株,占1.0%;统计分析结果显示:年龄≥60岁、BMI≥24kg/m2、合并基础疾病、急诊手术、切口长度≥10cm,手术时间≥3h,有侵入性操作以及住院≥10d均能够显著影响术后感染的发生率(P0.05);其中,年龄≥60岁、BMI≥24kg/m2、切口长度≥10cm以及住院时间≥10d是普外科术后感染的独立危险因素。结论普外科术后切口感染的因素是多方面的,应从患者自身因素、手术因素、医护人员因素以及医院管理因素等方面综合考虑,加强对手术患者的管理,降低感染率。
[Abstract]:Objective to explore the risk factors of postoperative infection in general surgery, and summarize the coping strategies according to the related factors to reduce the infection rate.Methods from June 2012 to June 2015, 1 200 patients undergoing general surgery were retrospectively analyzed. Single factor and multivariate logistic regression analysis was used to analyze the infection rate, the distribution of specific infection sites and the distribution of main pathogens.Results among 1 200 patients, 71 cases were infected, the infection rate was 5.9%, and the first three sites of infection were lower respiratory tract, urinary system and upper respiratory tract.A total of 96 strains of pathogens were detected, of which 33 were Gram-positive bacteria (34.4cm), 62 Gram-negative bacteria (64.6%) and 1 fungus (1.0kg / m2). Statistical analysis showed that BMI 鈮，
