摘要
目的:探讨我院普通内科下呼吸道感染患者痰培养阳性标本的病原菌种类和耐药性情况,以规范使用抗生素。方法:回顾分析2009年10月~2010年4月49例患者的痰培养阳性标本病原菌种类和药敏试验结果。结果:检出致病细菌65株(包括G-杆菌47株、G+球菌18株)、真菌19株;多重耐药菌株十分普遍。结论:为避免盲目使用抗生素,及时、规范进行病原菌的采集和培养十分必要。
Objective: To discuss the categories of pathogens of culture-positive sputum specimens of the patients with lower respiratory tract infection in general internal medicine and the status of drug resistance in order to standardize the prescription of antibiotics.Methods: The categories of pathogens of culture-positive sputum specimens of 49 patients and the results of drug susceptibility test were retrospectively analyzed.The patients were hospitalized and treated from October 2009 ~ April 2010.Results: 65 pathogenic bacterial strains(including 47 strains of G bacilli,18 strains of G cocci) and 19 strains of fungi were detected.Multiple drug-resistant strains were commonly seen.Conclusion: It is necessary to timely standardize the collection and cultivation of the pathogenic bacteria so as to avoid the blind use of antibiotics.
