PREVALENCE OF PREGNANT WOMEN WITH OLIGOHYDRAMNIOS AND ITS EFFECT ON MATERNAL AND FETAL OUTCOME

Abstract

Oligohydramnios is a pregnancy condition characterized by low volume of amniotic fluid. Based on ultrasound measurement, it is defined as an amniotic fluid index (AFI) ≤ 5cm and associated with adverse fetal and maternal outcomes. To study the prevalence of oligohydramnios and its effect on maternal and fetal outcome in third trimester (≥ 28 weeks) of pregnant women admitted at AL-Sadaqa Teaching Hospital in the period of study from 1st January to 31st December 2020. This study is a prospective descriptive study was performed at AL-Sadaqa Teaching Hospital, Gynecology and Obstetrics Department among 100 pregnant women in third trimester diagnosed as oligohydramnios by ultrasound (AFI≤ 5cm). The results were analyzed by using the statistical package social software (SPSS), version 25. The study showed the prevalence of oligohydramnios during study period was (1.5%), and the mean age of the affected women was 27.72 ± 6.8 years. The half of the cases were in age group between 20-29 years (50%) and the gestational age were between 37-40 weeks (50%), and slightly more than half of the women were nulliparous (58%). The rate of caesarean section was (56%), and the most indication for cesarean section was fetal distress (42.9%). The fetal complications showed in this study were low birth weight (40%), preterm birth (27%) and meconium aspiration (11%). The Apgar score <7 in 5th minutes was (17%) of the newborns and the rate of perinatal mortality was (7%). The prevalence of oligohydramnios in this study was (1.5%) which is within the normal limit worldwide. The study showed that the oligohydramnios in a pregnant woman has many complications for the fetus as well as the mother, but it more dangerous for the fetus. For mother there is increase intervention in the form of induction of labor and cesarean delivery. An early detection of oligohydramnios, identification of the risk factors and its management may help in reduction of these complications.
