Intrauterine growth restriction and oligohydramnios among high-risk patients.

The purposes of this study were (1) to determine the prevalence of oligohydramnios (amniotic fluid index < 5.0 cm) among fetuses with intrauterine growth restriction (IUGR) and newborns identified as small for gestational age (SGA), and (2) among fetuses with IUGR, to determine the predictive accuracy of amniotic fluid index (AFI) < or = versus > 5.0 cm for adverse peripartum outcomes.

Sonographic estimate of birth weight among high-risk patients: feasibility and factors influencing accuracy.

Objective: This study was undertaken to determine the feasibility of detecting abnormal fetal growth among patients undergoing biophysical profile (BPP) and to identify the factors those influence the accuracy.

Study Design: Retrospectively singletons with reliable gestational age (GA) having a BPP were identified. Fetal growth restriction (FGR) and large-for-gestational age (LGA) were based on estimated or actual birth weight 10% or less or 90% or greater for GA, respectively.

Detecting fetal growth restriction or discordant growth in twin gestations stratified by placental chorionicity.

Objective: To use recommendations made by the Evidence-Based Medicine Working Group to determine the accuracy of sonographically estimated fetal weight to diagnose fetal growth restriction (FGR) (estimated or actual birth weight < 10% for gestational age [GA]) or discordancy in dichorionic and monochiorionic twin gestations.

Study Design: The inclusion criteria for this retrospective analysis were nonanomalous twins, reliable GA and sonographic estimate of fetal weight within 21 days of live births of both fetuses beyond 26 weeks. For likelihood ratio (LR) and odds ratio (OR), 95% confidence intervals (CIs) were calculated.
