下呼吸道铜绿假单胞菌的耐药性分析与相关危险因素探讨

目的对下呼吸道的铜绿假单胞菌的耐药性和相关危险因素进行探讨分析。方法在我院治疗的下呼吸道感染160例患者痰液标本分离出的菌株进行分析,分析多重耐药菌分布、耐药性和相关危险因素。结果我院下呼吸道感染以革兰阴性菌为主,绝大多数的菌株均有不同程度的耐药。抗生素滥用、有创检查等为铜绿假单胞菌耐药的危险因素。结论严格监控致病菌和高危因素,防止致病菌在医院内流行。

Analysis of drug resistance and risk factors of pseudomonas aeruginosa in lower respiratory tract infection

Objective To analyze and discuss the drug resistance and risk factors of pseudomonas aeruginosa in lower respiratory tract infection. Methods The sputum samples of 160 patients with lower respiratory tract infection were cultured to analyze the distribu- tion, drug resistance and risk factors. Results The main infective bacteria in our hospital was gram-negative bacteria, and most bacteria showed a certain resistance to different drugs. The risk factors were overuse of antibiotics and invasive test. Conclusion The best ways to reduce the drug resistance are strictly monitoring on pseudomonas aeruginosa and the high risk factors and to prevent the pathogenic bacte- ria spread in hospital.
