Correlation between Amniotic Fluid Index and Perinatal Outcome in Term Pregnancy

Abstract

The purpose of this study was to study and compare the perinatal outcome and mode of delivery in women with oligohydramnios, normal AFI and polyhydramnios group at term gestation having no complication. Methods: This was a prospective study of 600 singleton pregnancies with gestational age between 37 to 42 weeks without any complicating factor. The AFI was determined in all cases using four quadrant technique. The cases were divided in 3 groups based on their AFI; AFI ≤5 (Oligohydramnios), AFI>5-24, AFI ≥25 (Polyhydramnios) .Maternal outcome in form of mode of delivery, abnormal fetal heart rate and cesarean section for fetal distress were studied and perinatal outcome in the form of meconium stained liquor, apgar score at 1 and 5 minute, birth weight, NICU admissions were studied. Results: The groups had no statistical difference in age, parity, gestational age. There was no statistical difference in regards to MSL,NICU admissions, less apgar score at 1 and 5 minute, birth weight <2.5kg, non reassuring fetal heart rate, indications for cesarean sections. But the group with oligohydramnios had more number of cesarean sections which was statistically significant. Conclusion: Oligohydramnios with AFI less than or equal to 5 is associated with statistically significant high cesarean delivery rate.
