Perinatal outcome in pregnancies with isolated oligohydramnios diagnosed before 37 weeks of gestation
Journal Title: International Journal of Medical and Health Research - Year 2019, Vol 5, Issue 3
Abstract
Background: Adverse pregnancy outcome in cases of oligohydramnios are the result of other pregnancy related complications that are associated with oligohydramnios rather than the result of oligohydramnios itself. Isolated oligohydramnios is comparable to that of low risk pregnancies with normal levels of amniotic fluid. There is only a small number of studies that address the management of isolated oligohydramnios at preterm. Objective: To study pregnancy outcome in cases of isolated oligohydramnios before 37 weeks of gestation and to study the perinatal outcome in isolated oligohydramnios diagnosed before 37 weeks of gestation. Methods: A retrospective study of singleton pregnancies diagnosed with isolated oligohydramnios before 37 weeks of gestation. Pregnancy outcome was compared with a matched control group of low-risk preterm pregnancies with normal levels of amniotic fluid. Results: Pregnancies complicated by isolated oligohydramnios were characterized by a higher rate of preterm deliveries most of which were iatrogenic, and a higher rate of labor induction and cesarean delivery. Neonates with isolated oligohydramnios were characterized by a lower birth weight and a higher rate of neonatal morbidity. These differences were eliminated when the analysis was limited to the subgroup of pregnancies with isolated oligohydramnios that were managed expectantly and delivered. Conclusion: Adverse pregnancy outcome in cases of isolated oligohydramnios diagnosed before 37 weeks appears to be related to a considerable degree to iatrogenic prematurity.
