Background: In this prospective cohort study, the perinatal outcome in idiopathic polyhydramnios compared with normal pregnancies was examined.
Methods: This was a prospective cohort study of 180 singleton pregnancies who received care at the referral gynecology clinic of Yasuj, Iran between 2018-2020. The inclusion criteria comprised singleton pregnancies, gestational age > 34 weeks; fetuses without structural and chromosomal abnormalities in pregnancy screening test, no maternal diabetes, negative TORCH negative screening test, no Rh factor isoimmunization. Polyhydramnios was defined as: (i) amniotic fluid index ≥ 24 cm; (ii) maximal vertical pocket of ≥ 8 cm. Perinatal outcomes were recorded in both groups.
Results: Postpartum hemorrhage (7.8% vs. 2.2; OR: 1.60; 95% CI 1.09-2.34) and cesarean delivery (51.11% vs. 21.11; OR: 1.88; 95% CI 1.42-2.50) and respiratory distress (4.4 v vs. 0; OR: 2.04; 95 C CI 1.75-2.80) was significantly higher in the idiopathic polyhydramnios (P ≤ 0.05) compared to normal pregnancy, which increased with severity of idiopathic polyhydramnios.
Conclusion: In conclusion, the results of the current study, suggest that idiopathic polyhydramnios may be associated with a higher rate of postpartum hemorrhage, cesarean delivery, and respiratory distress than a normal pregnancy.
