Is Cesarean Delivery Rate is Higher in Term Pregnancies with Oligohydramnios

Backgrounds: Oligohydramnios is one of the major causes of maternal and perinatal morbidity and mortality. Aim of current study was to evaluating cesarean Delivery Rate in term Oligohydramnios.Material and Method: A case control study was conducted from 2011 to 2014. 255 pregnantwomen (85cases in oligohydramnios and 170 cases in control group) were included,from 37 to 41 weeks. The inclusion criteria for the study purpose was: Thirty sevencompleted weeks of gestation, amniotic fluid index of ≤5 cm, intact membranes, singletonpregnancy with cephalic presentation. Following patients were excluded from the study:gestational age less than 37 completed weeks associated fetal malformations, rupturedmembranes, malpresentation and multiple gestation Fetal growth restriction, Chromosomalabnormalities, diabetes, maternal hypertensive disease and instrumental delivery. To determine the association between oligohydramnios and cesarean delivery rate chisquare and Fisher’s exact test were used if necessary.Result: There was not statistically significant difference regarding maternal age,gestational age, gravidity and parity between case and control group .Results of the presentstudy revealed that the rate of cesarean was significantly higher in oligohydramnios groupcompared to the control group (75.3% vs. 36.5% respectively).Conclusion: It can be concluded that an amniotic fluid index of ≤ 5 cm detected after 37 completed weeks of gestation is associated with significantly higher cesarean delivery rate.
