Among 70 women delivering infants with nuchal cords, there was a significantly higher incidence of meconium passage and severe variable fetal heart rate decelerations/fetal bradycardia in those who had intrapartum oligohydramnios, as defined by an amniotic fluid index less than or equal to 5.0 cm. Oligohydramnios in the presence of nuchal cord entanglement might represent an increased risk of ominous intrapartum fetal heart rate patterns.
