摘要 目的分析本院新生儿NICU早产儿院内感染败血症病原学特点及临床特点,高危因素,探讨早产儿感染的相关因素,为防治提供措施。方法对2009年1月-2012年6月收住本院NICU治疗的2 940例早产儿中的47例院内感染败血症的临床资料、病原菌、高危因素及治疗预后进行回顾性分析。结果早产儿院内感染败血症发生率占住院早产儿的1.6%,早产儿占院内感染的75%。病原菌中革兰阴性菌占53.1%,以肺炎克雷伯氏菌为主,大肠埃希菌-B内酰胺酶次之;革兰阳性菌占36.3%,凝固酶阴性的表皮葡萄球菌为主;真菌占10.6%,以念珠菌为主。药敏结果显示大肠埃希菌-耐B内酰胺酶、肺炎克雷伯菌对亚胺培南、哌拉西林他唑巴坦敏感率分别为100.0%;凝固酶阴性的表皮葡萄球菌MRCNS阳性对万古霉素敏感率为100.0%,真菌对氟康唑等常用抗真茵药均敏感。结论加强护理、严格无菌操作、合理使用抗生素及预防性抗真菌治疗,加强支持治疗,增强免疫力,是减少院内感染败血症及其并发症的发生的重要措施。
