羊水乳酸值对胎儿窘迫的预测价值

目的:探讨足月胎儿临产时的羊水乳酸水平对胎儿窘迫的预测价值。方法:收集2006年4月~2010年1月在我院阴道分娩的孕37~41+6足月单胎头位产妇,临产前B超胎儿发育正常,将产程中出现不良胎监图形130例和羊水粪染87例作为观察组,将产前正常胎监图形、羊水清且有良好结局的新生儿240例作为对照组,测定羊水乳酸水平,同时采脐血做血气分析。结果:羊水Ⅰ度及Ⅱ度粪染而胎儿监护正常的病例,其羊水乳酸值与对照组比较,差异无显著性意义(P>0.05),羊水Ⅲ度粪染的羊水乳酸值水平明显升高(P<0.05)。观察组发生胎儿窘迫及新生儿窒息的病例,其羊水乳酸水平明显高于对照组(P<0.05)。结论:胎儿缺氧时羊水乳酸水平升高,对诊断胎儿窘迫有一定的价值。
