Abstract
PURPOSE: To evaluate labor and perinatal outcomes of transient isolated polyhydramnios. MATERIALS AND METHODS: A retrospective cohort study (2008-2013) at a university-affiliated, tertiary medical center. Eligibility was limited to patients with singleton gestations, no maternal diabetes or known structural/chromosomal anomalies, and no rupture of the membranes prior to delivery, at > 34 weeks of gestation. All women underwent routine sonogram for estimation of fetal weight (sEFW) between 28-34 weeks of gestation, and a second routine sonogram at admission. We compared women diagnosed with polyhydramnios at the time of the sEFW which later resolved, with women who had normal AFI during the sEFW. RESULTS: Overall, 44 263 women delivered during this time period, of which 292 (0.7 %) with transient polyhydramnios (study group) and 29 682 with a normal amniotic fluid level (control group) were eligible for analysis. Women with transient polyhydramnios had a higher risk for assisted vaginal delivery (AVD), mainly due to abnormal/intermediate fetal heart rate tracings (aOR 2.3, 95 % CI 1.2-5.5), and a higher risk for cesarean delivery (CD), mostly because of labor dystocia (aOR 2.5, 95 % CI 1.2-5.1 for 1st stage arrest and aOR 3.4, 95 % CI 1.6-7.2) for 2nd stage arrest), suspected macrosomia (aOR 3.2, 95 % CI 1.6-6.6) and malpresentation (aOR 6.6, 95 % CI 2.0-21.1). CONCLUSION: Transient isolated polyhydramnios detected during the sonogram at 28-32 weeks of gestation is an independent risk factor for the need for obstetrical intervention during labor. © Georg Thieme Verlag KG Stuttgart · New York.
