摘要
目的探讨心血管内科住院患者感染部位及感染病原菌分布,为预防控制患者的感染提供依据。方法选取2014年1月-2015年5月于心血管内科治疗的670例住院患者为研究对象,统计不同部位的感染率,同时分析感染病原菌分布,研究中的数据采用SPSS17.0软件进行统计分析。结果 670例住院患者中发生23例医院感染,感染率为3.43%,其中上呼吸道感染和下呼吸道感染分别占34.78%和30.43%,高于其他部位;共分离出病原菌27株,其中革兰阴性菌、革兰阳性菌、真菌各17、8、2株,分别占62.96%、29.63%、7.41%,而革兰阴性菌中的肺炎克雷伯菌所占比例明显高于其他菌种,差异均有统计学意义(P<0.05)。结论心血管内科住院患者以呼吸道感染所占比例较高,其中又以肺炎克雷伯菌感染率相对较高,应给予充分的重视及干预。
OBJECTIVE To investigate the infection sites and distribution of pathogenic bacteria of hospitalized patients in the department of cardiology,in order to provide evidence for the prevention and control of infections.METHODS Totally 670 hospitalized patients in the department of cardiology from Jan.2014 to May 2015 were selected as the study subjects,and the nosocomial infection rate was statistically summarized,and the infection rates of different sites were analyzed,then the distribution situation of pathogenic bacteria were analyzed.The software SPSS17.0was used for statistical analysis.RESULTS Totally 23 cases of 670 hospitalized patients had nosocomial infections,the infections rate was 3.43%,the infection rates of upper respiratory tract infections and lower respiratory tract infections were 34.78% and 30.43%,higher than the infection rates of other sites.Totally 27 pathogenic bacteria were detected,the number of gram-negative bacteria,gram-positive bacteria and fungi were respectively 17,8and 2,the rates were respectively 62.96%,29.63% and 7.41%,and the proportion of Klebsiella pneumoniae which belonged to gram-negative bacteria was sighificantly higher than that of other bacteria（P〈0.05）.CONCLUSIONThe rate of respiratory tract infections of hospitalized patients in the department of cardiology is higher,and the infection rate of K.pneumoniaeis relatively higher,therefore,it should be paid to enough attention and intervention.
