摘要
目的对2018年-2022年重庆市人民医院心血管外科住院手术患者发生医院感染进行现状及危险因素调查分析。方法选择2018年1月-2022年12月在重庆市人民医院心血管外科住院手术患者作为研究对象,收集患者的一般资料,分析医院感染的发生率、病原菌的分布及危险因素。结果1136例心血管外科住院手术患者,术后有60例确诊为医院感染,感染率为5.28%,感染部位以下呼吸道感染为主,占比为51.67%,其次是手术部位感染,占比为16.67%;60例感染患者共培养出60株病原菌,其中革兰阴性菌29株占48.33%,革兰阳性菌28株占46.67%,真菌3株占5.00%;多因素分析结果显示,年龄、急诊手术、ASA分级、机械通气时间、入住ICU时间、引流管留置时间是心血管外科住院手术患者引发医院感染的独立危险因素(P<0.05)。结论心血管外科住院手术患者医院感染部位以下呼吸道感染为主,术后感染与年龄、手术类型、病情程度、机械通气、入住ICU及引流管留置时间密切相关。
OBJECTIVE To investigate the current status and risk factors for nosocomial infection in the hospitalized patients of cardiovascular surgery department of Chongqing People′s Hospital from 2018 to 2022.METHODS The patients who were hospitalized in cardiovascular surgery department of Chongqing People′s Hospital from Jan 2018 to Dec 2022 were recruited as the research subjects.The baseline data were collected from the patients,the incidence of nosocomial infection,distribution of pathogens and risk factors were observed.RESULTS Among 1136 hospitalized patients of cardiovascular surgery department,60 were diagnosed with postoperative nosocomial infection,51.67%of whom had lower respiratory tract infection,16.67%had surgical site infection.Totally 60 strains of pathogens were isolated from the 60 patients with infection,29(48.33%)of which were gram-negative bacteria,28(46.67%)were gram-positive bacteria,and 3(5.00%)were fungi.The result of multivariate analysis showed that age,emergency surgery,ASA grade,mechanical ventilation,length of ICU stay and drainage tube indwelling time were the independent risk factors for the nosocomial infection in the hospitalized patients of cardiovascular surgery department(P<0.05).CONCLUSION The patients with lower respiratory tract infection are dominant among the hospitalized patients with nosocomial infection in the cardiovascular surgery department.The postoperative infection is closely associated with the age,type of surgery,illness condition,mechanical ventilation,ICU stay and drainage tube indwelling time.
