The use of dinoprostone at third trimester in pregnant women with oligohydramnios

Abstract

Objective: The aim of this study was compare the efficacy of dinoprostone administration for labour induction in pregnant women with oligohydramnios and in pregnant women with normal amniotic fluid volume at third trimester. Methods: This retrospective study included 187 pregnant women between January 2015-December 2020 .Four quadrant technique was used to determine amniotic fluid index. The cases in the study were divided into two groups as Group:1(the ones with oligohydramnios) and Group:2 (the ones with normal amniotic volume) . Results: Age ,gravida, parity ,gestational week according to the last date of menstruation, Bishop score ,dilatation ,hours elapsed after the first contraction,hours elapsed after active contraction,labour entry time (hour) , time elapsed until delivery (hour) , birth weight, Apgar score 0th minute and 5th minute and their distribution between the groups showed similarity (p> 0.05). The values of amniotic fluid index(AFI)( (p <0.001) and effacement (p = 0.012) were found to be significantly higher in Group 2 compared to the values of the cases in the Group 1 (p <0.05).It was found in the analysis that the findings of premature rupture of membrane (PROM),oxytocin augmentation need,tachysystole,vaginal delivery rate, caesarean delivery rate ,meconium stained amnion rate,neonatal intensive care unit (NICU) need,postpartum hemorrhage,and transfusion need (p = 0.394) were similar between two groups (p> 0.05). Conclusion: We can state that dinoprostone can be used safely and effectively to induce labor in third trimester pregnancies both with normal AFI and oligohydramnios.
