Abnormal amniotic fluid volume is associated with increased maternal risk and perinatal morbidity and mortality. Until the advent of ultrasonography, the invasive nature of amniotic fluid volume assessment limited its clinical utility. Refinements in quantifying the noninvasive sonographic assessment of oligohydramnios and hydramnios have improved the ability of clinicians to identify at-risk pregnancies. This article reviews the available methods of amniotic fluid volume assessment and outlines a comprehensive approach to sonographic screening and monitoring.
羊水过少与产妇风险增加以及围产期发病率和死亡率升高相关。在超声检查出现之前，羊水容量评估的侵入性限制了其临床应用。在羊水过少和羊水过多的无创超声评估量化方面的改进，提高了临床医生识别高危妊娠的能力。本文综述了现有的羊水容量评估方法，并概述了超声筛查和监测的综合方法。
