1、住院早产儿医院感染临床分析住院早产儿医院感染临床分析【摘要】目的探讨早产儿医院感染发生率(院感率)的相关高危因素,揭示其病原学特点,指导临床工作。方法对869例早产儿的临床相关资料进行调查、登记和分析,总结早产儿医院感染(院感)与岀生体重、住院天数的关系,分析其病原体和耐药情况。结果869例早产儿院感率为3.6%,其中101例极低出生体重(VLBW)儿院感率10.9%,768例低出生体重(LBW)儿院感率2.6%❷;足月儿院感率仅0.7%;早产儿院感多发生在住院的第2〜3周,VLBW儿院感多发生在第3周,LBW儿院感多发生在
2、第2周;早产儿院感以下呼吸道感染最多见,其次为皮肤黏膜感染;病原体大多数是革兰氏阴性(G-)杆菌,其中肺炎克雷伯杆菌肺炎亚种高达57.1%,产ESBL酶杆菌和MRSA葡萄球菌达80.0%o结论早产儿尤其VLBW儿易发生院感,住院后2~3周内出现呼吸道感染多见,病原菌以耐药G-杆菌(肺炎克雷伯杆菌肺炎亚种)为主,临床上应高度注意,防止其在新生儿病室暴发传播。【关键词】医院感染;早产儿;病原学;耐药性AClinicalAnalysisofHospitalizedPrematureNeonates,NosocomialInfect
