Perinatal outcomes of idiopathic polyhydramnios.

OBJECTIVE: To investigate the perinatal outcomes of cases with idiopathic polyhydramnios.

STUDY DESIGN: Retrospective analysis of 160 singleton pregnancies that were under routine surveillance at the department of obstetrics from 2008 to 2010 was performed to assess perinatal outcomes. Finally, 59 cases were included as idiopathic polyhydramnios, and 101 cases were included as controls. Preterm delivery (<37 weeks), gestational age at birth, low birth weight (<2500 g), very low birth weight (<1500 g), macrosomia (>4000 g), 1- and 5-min APGAR scores <7, small for gestational age (SGA) fetuses, large for gestational age (LGA) fetuses, C-section rates, number of fetal distress, admission to neonatal intensive care unit (NICU) after delivery, neonatal death within the first 7 days, and deaths before the age of 1 year were selected as perinatal outcome variables.

RESULT: Significantly higher preterm labors and low 1- and 5-min APGAR scores were noted in the idiopathic polyhydramnios group compared with the control group.

CONCLUSION: Although perinatal outcomes are conflicting in literature, idiopathic polyhydramnios warrants close surveillance especially near term.
