Although amniotic fluid is mainly removed by fetal swallowing, some amount of fluid is absorbed by the fetal skin as well.Īmniotic fluid volume is related to gestational age. When fetal kidneys become functional at approximately 16 weeks, fetal urine also contributes to the fluid. Amniotic fluid is the ultrafiltrate of maternal plasma and passes through the fetal membrane through osmotic and hydrostatic forces. This fluid acts as a cushion for the growing fetus and facilitates the exchange of nutrients, water, and biochemical products between the mother and the fetus. Therefore, patients with borderline AFI should be monitored carefully during the antepartum and intrapartum period.Īmniotic fluid is the protective fluid contained in the amniotic sac of a gravid uterus. The borderline AFI group was associated with adverse perinatal and maternal outcomes which were significantly higher in this group compared to the control group. Maternal outcomes such as preterm delivery, meconium-stained liquor, and lower segment cesarean section in women with borderline AFI were significantly higher (p ≤ 0.001). The borderline AFI group had a higher rate of perinatal complications such as Apgar score of <7 (p = 0.001), respiratory distress syndrome (p = 0.001), neonatal intensive care unit admission (p <0.001), intrauterine growth restriction (p < 0.001), and low birth weight (p < 0.001). Data analysis was done using SPSS version 23 (IBM Corp., Armonk, NY, USA). Fetal and maternal outcomes were compared between the two groups. Of the included women, 100 were cases with borderline AFI, and 100 were control with normal AFI. Women with singleton pregnancy in their third trimester were enrolled in this study after applying inclusion and exclusion criteria. This observational prospective study included 200 pregnant women who were admitted to Pradyumna Bal Memorial Hospital, Bhubaneswar from September 2019 to February 2021. In this study, we aimed to investigate the perinatal and maternal outcomes in borderline AFI versus normal AFI. The most commonly used method for measuring amniotic fluid is the amniotic fluid index (AFI). Amniotic fluid is a protective fluid in the amniotic sac of a gravid uterus that serves many crucial functions by becoming part of an indicator of a functioning fetoplacental unit during the intrauterine life of a fetus.
