重症监护病房中呼吸道感染菌监测及耐药感染因素的分析

目的对重症监护病房的多重耐药菌进行监测和耐药感染因素进行观察分析。方法我院确诊为呼吸道感染患者的137株菌株进行细菌鉴别,采用kb法药敏试验观察耐药率和分析可能造成感染的高危因素。结果我院ICU呼吸道感染以革兰阴性菌为主,多种格兰阴性菌都存在不同程度的耐药性,感染多重耐药菌的高危因素主要为年龄、住院时间、住院次数、COPD病史、气管切开、深静脉导管、抗生素使用时间和次数、留置胃管等。结论我院的重症监护病房的呼吸道多重耐药菌主要为革兰阴性菌,对多重耐药菌的合理监测和重视感染的高危因素对控制医院内感染极为重要。

Monitoring of respiratory tract infection bacteria in ICU and analysis of its risk factors

Objective To monitor the multiple drugs resistance （MDR） bacteria in ICU and to analyze the risk factors for MDR bacteria infection. Methods 137 strains of bacteria, which were isolated from patients confirmed with respiratory tract infection, were an- alyzed by KB drug sensitive test to observe their drug resistance. Results The main infective bacteria in our hospital was Gram-negative bacteria, which showed different degrees of drug resistance. The high risk factors of MDR strain infection were age, duration of hospital stay, hospitalized times, history of COPD, tracheotomy, central venous catheters, use of antibiotics, and gastric intubation. Conclusion Gram negative bacteria is the main infective bacteria in ICU in our hospital. It is very important for respiratory tract infection reduction to detect MDR and pay attention to the risk factors of MDR strain infection.
