Fetomaternal Outcomes in Cases of Oligohydramnios At Term

Abstract Introduction: Oligohydramnios is a term used to describe amniotic fluid volumes that are below the minimum for gestational age. A subjective estimate of reduced amniotic fluid volume is also acceptable. It is detected by ultrasound examination, preferably based on an objective measurement such as AFI (Amniotic fluid volume) ≤5cms or DVP (Deepest vertical pocket) < 2cms. About 4.4% of all pregnancies at term are complicated by oligohydramnios, although its frequency is just about 1% in preterm pregnancies. Objectives: To evaluate the effects of isolated oligohydramnios on labour, delivery mode and its neonatal outcome in term pregnancies. Materials and Methods: This was a case control study conducted in 100 pregnant women having oligohydramnios after 37 weeks of gestation compared with 100 controls with no oligohydramnios. Outcome was observed in the form of mode of delivery, caesarean indications & neonatal outcomes which include birth weight, APGAR Score, NICU Admission, intrapartum fetal distress, meconium aspiration syndrome and perinatal death. After collection of data the Statistical package for social sciences (SPSS) version 20.0 was used for data analysis. Results: In the present study majority of the participants (62% in study group and 52% in control group) were in the age group > 30 years and most of the subjects were primigravida in both groups (61% and 68% respectively). Conclusion: The study concluded that oligohydramnios is associated with increased risk of cesarean section and poor neonatal outcomes.
