MATERNAL AND PERINATAL OUTCOME IN BORDERLINE OLIGOHYDRAMNIOS: A HOSPITAL-BASED STUDY
Introduction: Amniotic fluid index (AFI) between 5.1 to 8 is termed as borderline oligohydramnios. Oligohydramnios has been linked with perinatal morbidity and mortality, however there are paucity of data on the effect of outcome of pregnancy among the isolated borderline oligohydramnios. This study studied the outcome of borderline oligohydramnios.
Methods: Pregnant women after 30 weeks period of gestation, with AFI 5-8 were included in the study. Pregnancy with hypertension, diabetes, heart disease, congenital anomalies in fetus, previous cesarean section or any uterine surgery were excluded from the study. Collected data were analyzed using descriptive statistics.
Results: 140 pregnancy were enrolled. The mean age(SD) of study population was 24.7(4.0) years. 60%. The mean(SD) gestational age at the presentation was 38.8(1.6) weeks, with range from 35.3 weeks to 42.5 weeks. Induction of labour was done in 80.2%, normal delivery was possible only in 42.1%. Meconium-stained liquor was present in 27.1%. The most common indication of cesarean section was Non-reactive Non-Stress Test (NRNST) among 51.9%. Postpartum Haemorrhage(PPH) was observed in 11.4%. There was no perinatal depression, the mean(SD) of birth weight was 2.9(0.4) kgs. 6.4% of the cases required nursery admission, among them the common causes of nursery admission were neonatal sepsis (45%) and various causes of respiratory-distress (55%. There was no neonatal or maternal death.
Conclusions: Borderline oligohydramnios was more among nulliparous with higher rate of caesarean section. However, adverse outcome like PPH, neonatal infection and respiratory distress are less frequent findings and there was no perinatal mortality.
Keywords: Borderline oligohydramnios, perinatal, maternal, neonatal, outcome.
