ROCs produced no diagnostic cutoff values for AFI or largest pocket and prediction of any of the chosen parameters.ĬONCLUSIONS: Antepartum oligohydramnios is associated with an increased risk of fetal heart rate abnormalities. Subjects with an AFI of 5.0 cm or less had a higher rate of cesarean for fetal distress, but this did not reach statistical significance. RESULTS: An AFI of 5.0 cm or less was significantly associated with an abnormal antepartum fetal heart rate (FHR) tracing but not with cesarean delivery, meconium-stained fluid, Apgars less than 7, or NICU admission. Chi-square analysis, Fisher's exact test, t tests and receiver-operator curves (ROCs) were used for analysis. Inclusion criteria included a nonanomalous fetus and delivery within 7 days of the last antepartum surveillance test (modified biophysical profile). Data, including the reasons for testing, the testing results, and pregnancy outcome were abstracted from these records. STUDY DESIGN: The antepartum testing records of 779 women seen over a 12-month period were reviewed.
OBJECTIVE: To determine whether an antepartum amniotic fluid index (AFI) of 5.0 cm or less is a predictor of adverse perinatal outcome.
