    摘要:

    目的了解某院新生儿重症监护室(NICU)新生儿入院时多重耐药菌(MDRO)定植情况。方法对2013年4—11月入住某院NICU的293例新生儿在入院时全部常规进行鼻拭子耐甲氧西林金黄色葡萄球菌(MRSA)、咽拭子MRSA、肛拭子产超广谱β内酰胺酶(ESBLs)细菌及耐万古霉素肠球菌(VRE)定植菌筛查。结果293例新生儿中,61例检测出MDRO,MDRO定植率为20.82%。日龄<3 d新生儿组MDRO筛查阳性率(5.92%)低于日龄3~6 d新生儿组(37.74%)及 7~28 d新生儿组(43.66%),差异均有统计学意义(P<0.001)。定植MDRO种类以产ESBLs菌所占比率最高(83.60%);MDRO定植部位以肛门比率最高(88.52%)。结论新生儿的肛门及粪便是NICU中MDRO的一个重要来源;NICU应重视日龄>3 d新生儿肛拭子MDRO的定植菌筛查,并对筛查阳性者采取相应的隔离措施,防止MDRO的传播。

    Abstract:

    ObjectiveTo investigate colonization of multidrugresistant organisms (MDROs) in neonatal intensive care unit (NICU) newborns on admission. MethodsFrom April to November 2013, 293 newborns who admitted to  NICU of a hospital were screened for methicillinresistant Staphylococcus aureus (MRSA) by nasal and throat swabs and for extendedspectrum βlactamases  (ESBLs) bacteria and vancomycinresistant Enterococcus (VRE) by anal swabs.ResultsOf 293 newborns, 61 were detected MDROs (20.82%).The positive rate of MDROs screening  in newborns aged <3 days(5.92%) was lower than those aged <3-6 days(37.74%) and  7-28 days (43.66%),the difference was significant (P=0.000). The major colonized MDROs were ESBLsproducing bacteria(83.60%), the major colonized site was anus(88.52%). ConclusionNeonatal anus and stool are important sources of MDROs in  NICU; more attention should be paid to colonization screening for MDROs by anal swabs in newborns aged >3 days, and appropriate isolation measures should be taken for positive screening patients to prevent the transmission of MDROs.
