BIRTH:孕早期常规阴道微生物学检查可有效避免早产新生儿的发生

2015-05-22 MedSci MedSci原创

背景:孕妇早期发生阴道炎症易导致早产儿的发生。该研究的目的在于:针对患有无症状的阴道炎的孕妇,将产前筛查和治疗的计划同常规孕期护理结合的长期效果。方式:研究人员回顾性地收集了2005-2014年间第三妇幼保健院所有单胎高危妊娠产妇的相关数据,并将其进行数据分析。实验组的孕妇为计划妊娠且胎龄为10-16周并进行产前检查的妇女。她们进行常规筛查并以革兰染色判断是否存在无症状性阴道炎症,尤其是细菌性阴道

背景:
孕妇早期发生阴道炎症易导致早产儿的发生。该研究的目的在于:针对患有无症状的阴道炎的孕妇,将产前筛查和治疗的计划同常规孕期护理结合的长期效果。


方式:
研究人员回顾性地收集了2005-2014年间第三妇幼保健院所有单胎高危妊娠产妇的相关数据,并将其进行数据分析。实验组的孕妇为计划妊娠且胎龄为10-16周并进行产前检查的妇女。她们进行常规筛查并以革兰染色判断是否存在无症状性阴道炎症,尤其是细菌性阴道炎、念珠菌性阴道炎和滴虫性阴道炎。孕妇根据相应的临床治疗方案进行对症治疗。对照组为不接受常规筛查和临床治疗的孕妇。两组中对孕妇实施同样的产前护理。实验观察的主要变量为新生儿是否出现早产。

结果:

在单胎妊娠的20052名孕妇中,实验组有8490名孕妇,占42.3%,她们接受常规筛查及相应治疗。实验组和对照组孕妇的平均孕周数分别为38.8周和37.5周(范围分别为38.8 ± 2.6周、37.5 ± 4.3周,p < 0.001);实验组早产新生儿的发生率明显低于对照组(9.7%: 22.3%; p < 0.001),且实验组低出生体重儿、死胎、孕妇晚期流产的发生率也低于对照组(p < 0.001)。

结论:

结果表明,对孕妇进行常规阴道微生物学检查并采取相应治疗是有效的,可以明显降低早产新生儿的发生率。如果高风险的妇幼保健院护士将其纳入孕妇常规产前护理内容,这一简单的健康干预措施则会起到明显降低早产新生儿、低出生体重儿发生率的作用,而且可以避免不良生育后果,对母婴及其家庭都是有利而无害的。
