1、新生儿定植菌筛查阳性结果分析及相关因素研究摘要:目的了解新生儿入院时的定植菌的阳性结果,找出相关因素,针对其相关因素进行干预,降低定植菌的发生率。方法选取2014年8月〜2015年7月在某院新生儿室住院的736例新生儿,在入院时取鼻前庭拭子和直肠拭子分别接种于耐甲氧西林金黄色葡萄球菌(MRSA)鉴定培养基(ChromIDMRSA)和产超广谱3内酰胺酶(ESBLSs)肠杆菌鉴定培养基(ChromIDESBLs)培养筛查,统计筛查结果并分析相关影响因素。结果736例新生儿中MRSA的阳性结果与羊水情况、取样日龄有关,其P值分别为0.044和0.000,关键词:新生儿;定植菌

7、细菌(尤其是耐药菌株)在新生儿室的定植导致新生儿在医院感染发病率和病死率明显增高[1]。本文通过对某院736例入院新生儿进行常规进行耐甲氧西林金黄色葡萄球菌(MRSA)鉴定培养基(ChromIDMRSA)和产超广谱0内酰胺酶(ESBLSs)肠杆菌鉴定培养基(ChromIDESBLs)培养筛查,分析其结果,找寻与新生儿定植菌阳性结果相关的因素,为降低新生儿的细菌的定植提供依据。1资料与方法1.1一般资料选取2014年8月1日〜2015年7月31日在某院新生儿室住院的736例新生儿在入院时取鼻前庭拭子和直肠拭子分别接种于ChromIDMRSA
