腹膜炎患者术后医院感染危险因素分析与预防

Analysis and prevention on the risk factors of postoperative nosocomial infections in patients with peritonitis

目的探讨腹膜炎患者术后医院感染的危险因素及防治措施,为其预防与治疗提供依据。方法选取2011年1月-2015年8月进行手术治疗的165例腹膜炎患者为研究对象,将其术后医院感染率进行统计,采用logistic分析与医院感染的关系,并根据研究结果进行针对性干预。结果 165例腹膜炎患者共发生14例术后医院感染,感染率8.48%,高龄、体质量指数较高、有基础疾病、手术时间较长、术前营养情况较差、引流及开腹手术患者的感染率明显高于其他患者,logistic分析显示,上述指标均与患者术后医院感染有密切的关系(P<0.05)。结论高龄、体质量指数较高、伴发基础疾病、手术时间较长、术前营养情况较差、引流及开腹手术均为腹膜炎患者术后医院感染危险因素,应给予针对性的防治性干预。

OBJECTIVE To investigate the risk factors of postoperative nosocomial infections in patients with peritonitis,in order to provide evidence for the prevention and treatment.METHODS Totally 165 patients with peritonitis undergoing surgery from Jan.2011 to Aug.2015 were selected as the research subjects,and the postoperative nosocomial infection rate of all the patients was analyzed and the relationship between the research indexes and nosocomial infections were analyzed by the logistic analysis,the targeted inventions were done according to the study results.RESULTS Totally 14 cases of 165 patients with peritonitis had postoperative nosocomial infections,the infection rate was 8.48%.The infection rates of patients with higher ages,higher BMI value,underlying diseases,longer operation time,worse preoperative nutritional status,drainage and open operation were obviously higher than those of other patients,and these indexes all had close relationship with the postoperative nosocomial infections of patients according to the logistic analysis（P〈0.05）.CONCLUSION The higher ages,higher BMI value,complication with underlying diseases,longer operation time,worse preoperative nutritional status,drainage and open operation are the risk factors of postoperative nosocomial infections in patients with peritonitis,and the patients should be given targeted invention for prevention and treatment.
