To determine the efficacy of sonographic assessment of amniotic fluid volume (AFV) in predicting intrapartum fetal distress in pregnancies with intrauterine growth retardation (IUGR) compared with the nonstress test (NST).
A prospective study of 242 pregnancies with IUGR who underwent antepartum assessment of AFV and NST with intrapartum continuous FHR monitoring was conducted and analyzed.
AFV was a reliable predictor of intrapartum fetal distress with sensitivity, specificity, positive and negative predictive values of 84.0%, 83.41%, 36.84% and 97.84%, respectively. The efficacy of AFV was comparable with that of the NST.
Sonographic assessment of AFV is an effective predictor of intrapartum fetal distress in pregnancies with IUGR.
与无应激试验（NST）相比，确定超声评估羊水体积（AFV）对预测宫内生长受限（IUGR）妊娠分娩期胎儿窘迫的有效性。
对242例IUGR妊娠进行前瞻性研究，这些孕妇在产前接受了AFV评估和NST，并在分娩期进行了连续胎心监护，随后进行分析。
AFV是分娩期胎儿窘迫的可靠预测指标，其敏感性、特异性、阳性预测值和阴性预测值分别为84.0%、83.41%、36.84%和97.84%。AFV的有效性与NST相当。
超声评估AFV是IUGR妊娠分娩期胎儿窘迫的有效预测指标。
