OBJECTIVE
The objective of this study is to determinate the influence of oligohydramnios on perinatal outcome in term pregnancies.
METHODS
Retrospective case-control study.
METHODS
II. Gynecologic Obstetrics Department, Comenius University, Bratislava.
METHODS
Authors analysed a group of 372 single pregnancies after completed 37th week of gestation in years 2011 to 2015 with sonographic diagnosis of isolated oligohydramnios. A control group was created with matched patients by age and parity with normal amniotic fluid volume.
RESULTS
We found significant differences in number of obstetric intervention between the two groups: patients with oligohydramnios had higher number of cesarean sections (71% compared to 33.9% in control group) and also the number of inductions was significantely higher (27.4% compared to 18.8%). The most common indication for cesarean delivery was presumed fetal hypoxia. We did not find any differences in numbers of neonates with low Apgar score, low umbilical cord pH and admission to neonatal intensive care unit.
CONCLUSIONS
The finding of isolated oligohydramnios after 37th week of gestations is associated with higher risk of obstetric intervention without any association with adverse perinatal outcome.
