The purpose of this study was to determine whether an intrapartum assessment of amniotic fluid identifies a pregnancy that is at risk for an adverse outcome.
Parturients who were admitted for delivery were assigned randomly to have the amniotic fluid assessed either by amniotic fluid index or by the presence of a 2 x 1 pocket.
The amniotic fluid index was obtained in 499 pregnancies, and the 2 x 1 technique was performed in 501. Oligohydramnios was diagnosed in 25% of amniotic fluid index pregnancies versus 8% with the use of the 2 x 1 pocket technique (P <.001). Both techniques failed to identify patients who underwent an amnioinfusion for fetal distress (P=.864) or who experienced variable (P=.208) or late decelerations (P=.210) that influenced delivery, fetal distress in labor (P=.220), caesarean delivery for fetal distress (P=.133), and admission to neonatal intensive care unit (P=.686).
Neither the amniotic fluid index nor the 2 x 1 pocket technique that was undertaken as a fetal admission test identifies a pregnancy that is at risk for an adverse outcome.
本研究的目的是确定产时羊水评估能否识别出有不良结局风险的妊娠。
入院分娩的产妇被随机分配，通过羊水指数或2×1区域羊水的存在情况来评估羊水。
499例妊娠获得了羊水指数，501例采用了2×1技术。羊水指数法诊断羊水过少的妊娠占25%，而采用2×1区域羊水技术的为8%（P<.001）。两种技术均未能识别出因胎儿窘迫接受羊膜腔灌注的患者（P=.864），或经历影响分娩的变异减速（P=.208）或晚期减速（P=.210）、产时胎儿窘迫（P=.220）、因胎儿窘迫行剖宫产（P=.133）以及入住新生儿重症监护病房的患者（P=.686）。
作为胎儿入院检查采用的羊水指数法和2×1区域羊水技术均不能识别出有不良结局风险的妊娠。
