医院内外获得性支气管-肺感染致病菌对比分析

目的通过对支气管一肺感染病人的菌种分布及药敏结果的分析，为临床寻找合适的治疗药物，为合理使用抗生素、提高疗效提供依据。方法取病人痰标本进行培养，获得致病菌及药敏试验结果。结果院内感染与院外感染病原菌分布不同；年龄大与年龄小也不同；绝大部分病原菌对喹诺酮类抗生素敏感。结论根据细菌培养和药敏试验结果有针对性地合理使用抗生素，才能提高支气管一肺感染病人的疗效，减少抗生素的滥用，有效控制耐药菌株的产生。

Comparative Analysis of Acquired Bronchial-Pulmonary Infections Pathogens Inside and Outside The Hospital

[ Objective] Through the analysis of strain distribution and drug-sensitivity of the bronchial-pulmonary infections, to find suitable drug for chnical treatments, and provide basis for improving efficacy and the rational use of antibiotics. [ Methods ] Sputum samples of patients were collected and cultured, pathogens and antimicrobial susceptibility test results were obtained. [ Results ] The pathogen distribution of nosocomial infection and community infection were different ; that of younger patients and older ones were dif- ferent; most pathogens were sensitive to the quinolones antibiotics. [ Conclusion ] Rational use of antibiotics is based on the results of bacterial culture and drug sensitivity test, so as to improve healing efficacy of bronchial-pulmonary infected patients, reduce the a- buse of antibiotics and effectively control the emergence of drug-resistant strains.
