摘要 目的探讨隐匿性绒毛膜羊膜炎产妇胎膜组织中B族链球菌(GBS)的存在状况及对新生儿的影响。方法收集2013年6月-2014年12月在该院妇产科分娩时无宫内感染的临床表现,但胎盘、胎膜娩出后肉眼观符合典型组织学绒毛膜羊膜炎的病例共210例(最终病检证实196例)作为实验组;另收集同期分娩的无宫内感染临床表现,也无组织学绒毛膜羊膜炎表现的病例共267例作为对照组;于胎盘、胎膜娩出后立即采取双份新鲜胎膜组织棉拭子,一份应用荧光PCR探针定性的方法检测其GBS的存在状况,另一份用选择性培养基培养GBS;并追观新生儿临床感染情况。结果实验组PCR法检出GBS阳性21例(10.71%),培养法检出GBS阳性13例(6.63%);对照组PCR法检出GBS阳性2例(0.75%),培养法检出GBS阳性0例;两组比较差异有统计学意义(P<0.05)。实验组中有32例新生儿感染(16.33%);对照组中有5例新生儿感染(1.87%),两组比较差异有统计学意义(P<0.05)。结论隐匿性绒毛膜羊膜炎是新生儿GBS感染的危险因素,由于其在临床上缺乏典型的阳性指征,仅靠生后胎盘病理检查才能发现,易漏诊而延误治疗,对新生儿的危害巨大。荧光PCR法结合新鲜胎膜拭子是一种快速、准确检测GBS感染的方法,有利于临床高危产妇的筛查以及指导临床预防性应用抗生素,对新生儿感染的诊断和治疗也意义重大。
