摘　　要：目的针对胸外科手术患者发生医院感染的现状进行目标性监测,并分析发生医院感染的危险因素,为预防与控制医院感染提供参考依据.方法对某三级甲等医院2012年胸外科手术患者进行医院感染的前瞻性调查,共计576例.应用病例对照方法,将医院感染的病例作为"病例组",无感染的病例作为"对照组",分析各相关因素与医院感染的关系.结果 576名术后患者共计发生医院感染45例,50例次,感染发生率为7.8%,感染例次率8.7%.感染部位最多的是下呼吸道,占64%;检出病原菌52株,其中革兰氏阴性杆菌43株,占82.69%,其次为革兰氏阳性杆菌7株,占13.46%,真菌2株,占3.85%.单因素分析结果表明患者年龄、住院季节、手术持续时间、是否输血与医院感染关系较为密切.Logistic回归分析结果显示:性别、住院季节、是否有长期大量吸烟史、是否有糖尿病、手术持续时间、失血量是医院感染的独立危险因素.结论加强医院感染管理,针对胸外科术后患者医院感染现状和特点以及术后感染的危险因素采取有效措施,可降低医院感染的发生率.Objective Use targeted monitoring to understand the current status of nosocomial infections in the thoracic surgery department and to explore the risk factors,so as to provide basis for prevention and control measures of nosocomial infections.Methods All patients（a total of 576）in the thoracic surgery department of a tertiary teaching hospital in 2012were prospectively surveyed.Application case-control study defining the nosocomial infections cases as＂case group＂,no cases as a＂contrast group＂,analyzed the relationship between the related factors and the nosocomial infections.Results Of the 576surgery department patients investigated,45patients and 50cases suffered from nosocomial infections with an infection rate of 7.8%,and the infection case-rate was 8.7%.Lower respiratory tract infection ranked the first（64%）,52strains were detected of which 43strains were Gram-negative bacteria（82.69%）,7 strains were Gram-positive bacteria（13.46%）and 2strains were fungi（3.85%）.Single factor analysis showed the main influencing factors included the age of patients,season of hospital,the duration of operations,blood transfusion.The analysis of logistic regression analyses showed that the independent risk factors of nosocomial infections were the gender,the season of hospital,the long history of heavy smoking,diabetes,the duration of operations,blood loss.Conclusion Strengthen the nosocomial infections management,in view of the current status and characteristics of the patients in the thoracic surgery department with nosocomial infections and the risk factors take effective measures,reduce the incidence of nosocomial infections.
