Implication

Prospective cohort study reveals low predictive sensitivity of amniotic fluid index in prolonged pregnancy, indicating routine scanning may trigger unnecessary obstetric interventions.

Key Points

To assess whether late-pregnancy ultrasound detection of reduced amniotic fluid index or a shallow single deepest pool reliably predicts adverse perinatal outcomes.
Prospective, double-blind cohort study conducted at a university teaching hospital involving 1,584 pregnant women at or beyond 40 weeks of gestation.
Liquor volume was examined using ultrasound to identify a single deepest pool <2 cm and calculate the amniotic fluid index (AFI <5 cm).
Perinatal outcomes measured included perinatal death, meconium aspiration, birth asphyxia, labour interventions for fetal distress, cord arterial pH <7, and neonatal unit admission.
An AFI <5 cm was significantly associated with birth asphyxia, meconium aspiration, caesarean delivery for fetal distress, low Apgar scores, and cord arterial pH <7, while a single deepest pool <2 cm showed no significant association.
The clinical sensitivity of AFI <5 cm was poor, detecting only 28.6% of major adverse outcomes, 12.0% of fetal distress cases during labour, and 11.5% of neonatal unit admissions.
