目的:分析小儿肺炎常见的致病菌,为临床用药提供参考。方法:对临床肺炎患儿检查痰培养,分析比较所培养菌的阳性率及药敏结果。结果:小儿肺炎以条件致病菌感染为主,药敏结果以头孢三代及加酶抑制剂为主。结论:增强患儿免疫力,临床合理规范用药以减少耐药性的发生至关重要。 Objective: To analyze common pathogenic bacteria in children with pneumonia and provide reference for clinical use. Methods: The sputum culture of children with clinical pneumonia was examined. The positive rate and drug susceptibility results of the cultured bacteria were analyzed and compared. Results: The infection of opportunistic bacteria was the main cause of pneumonia in children. The results of drug susceptibility were mainly based on the third generation of cephalosporins and inhibitors of adding enzyme. Conclusion: It is very important to enhance the immunity of children and to standardize the medication in order to reduce the drug resistance.
