摘要 目的了解新生儿败血症的病原学分布及其耐药性情况,为临床及时明确病原和抗菌药物应用提供参考。方法对上海市浦东新区人民医院儿科新生儿室在2008年1月~2011年12月间收治的117例败血症患儿血培养检出菌及其药敏结果进行回顾性分析。结果 117例新生儿败血症的血培养标本中检出病原菌117株,其中革兰阳性菌占88.89%,革兰阴性菌占11.11%,产气肠杆菌、奇异变形菌均为0.85%。革兰阳性菌以葡萄球菌为主,前3位分别是金黄色葡萄球菌31.62%,表皮葡萄球菌17.95%,溶血葡萄球菌13.68%。117株病原菌中凝固酶阴性葡萄球菌(CNS)占45.30%。革兰阴性菌前3位分别是大肠埃希菌5.13%,肺炎克雷白杆菌2.56%,阴沟肠杆菌1.71%。CNS及金黄色葡萄球菌对青霉素G耐药率最高,分别为94.34%,94.59%,其次为头孢西丁,耐药率分别88.68%,78.38%;对苯唑西林、红霉素的耐药率>50%;对头孢唑林、氨苄西林/舒巴坦、磷霉素、利福平耐药率低(<17%);对糖肽类抗菌药物替考拉宁、万古霉素未产生耐药。革兰阴性菌对氨苄西林、哌拉西林耐药率较高;对阿米卡星、美罗培南、亚胺培南、头孢吡肟未产生耐药。结论该院新生儿败血症的病原菌以革兰阳性葡萄球菌为主,CNS为主要病原菌,对青霉素、头孢西丁等常用抗菌药物普遍耐药,头孢唑林耐药率较低,临床治疗上应根据病原菌药敏结果合理选用抗菌药物,以提高治疗效果,减少耐药菌株的产生。
