新生儿重症监护室感染的危险因素研究

目的探讨新生儿重症监护室（NICU）感染的危险因素。方法采用回顾性调查方法对我院2009年1月至2009年12月NICU收治的新生儿共816例感染情况进行分析。结果 816例新生儿中,发生感染42例,感染率为5.15%。42例发生感染的新生儿,其中31例发生1个部位感染,11例发生2个部位感染。感染部位均以呼吸道感染为首位,其次为胃肠道、皮肤、口腔及其他部位。比较不同体重新生儿感染的情况,发现体重越低,感染的机会越大（P〈0.01）;胎儿期间羊水有污染的新生儿感染率显著高于没有污染的新生儿（P〈0.01）。结论感染的危险因素主要有自身的感染、环境引起的感染、操作引起的感染和用药引起的感染。
