儿科住院患者呼吸道感染病原菌分布及耐药性分析

目的了解和探讨儿科住院患者呼吸道感染的主要病原菌及耐药性,为临床诊断与治疗提供实验室依据。方法对2005年1月-2007年12月儿科送检痰标本中检出的病原菌,采用全自动细菌鉴定仪VITEK-32进行细菌鉴定和药敏试验,结合K-B药敏试验方法。结果共分离出病原菌203株,以革兰阴性杆菌为主,占52.2%,革兰阳性球菌占11.3%,真菌占36.5%,按分离率高低,排在前3位病原菌依次为肺炎克雷伯菌、大肠埃希菌、金黄色葡萄球菌分别占20.9%、19.4%、17.8%。结论临床在抗菌药物使用中应加强病原菌检测,根据药敏结果科学选药,提高治疗效果,延缓细菌对抗菌药物耐药性的产生。
