Nomograms for amniotic fluid in normal pregnancies have been developed by dye-determined methods, by AFI, dye-dilution and direct measurement, and sonographic estimate. The 5 th and 95 th percentiles have been defined for AFI, single deepest pocket (SDP), the 2-diameter pocket, and dye-directed techniques across gestational ages as fluid levels have been found to vary significantly throughout pregnancy. Normal amniotic fluid volume has been defined in various ways. Any decrease or increase in the volume of amniotic fluid may lead to pregnancy complications. Amniotic fluid volume at any time is a balance between production and consumption and varies with gestational age. Studies have revealed that AFI is an accurate criterion for estimating adequate placental function. One of the indices in assessing abnormalities in amniotic fluid volume (AFV) is the sonographic assessment of amniotic fluid index. It has been shown to be useful in predicting adverse outcomes such as fetal distress, meconium aspiration, cesarean delivery, and fetal mortality. The amniotic fluid volume is one of the several parameters used to assess fetal well-being and perinatal outcomes. Conclusions:īorderline AFI is associated with an increased risk of adverse pregnancy outcomes in low-risk Nigerian women. The results showed that borderline amniotic fluid index was associated with increased risk of adverse pregnancy outcomes including intrapartum fetal distress, Appearance, Pulse, Grimace, Activity, and Respiration (Apgar) score <7 in 5 min, and birthweight <2.5 kg, and these were statistically significant ( P = 0.04, 0.01, and 0.04, respectively). The data were analyzed using the Statistical Package for the Social Sciences (SPSS) version 22 software. ![]() These women were followed up till delivery, and pregnancy outcomes were determined. ![]() Fifty-seven subjects with borderline amniotic fluid index were matched with an equal number of subjects with the normal amniotic fluid index for gestational age, age of the parturient, and parity. A total of 114 pregnant women attending the antenatal clinics with singleton pregnancies at gestational age 37 to 41 + 6 weeks were recruited over a 5-month period. This was a prospective cohort study conducted at two health facilities in Delta State, Southern Nigeria. To compare the pregnancy outcomes of Nigerian women with borderline and normal amniotic fluid index. There is, however, a dearth of studies on the pregnancy outcomes of women with borderline AFI in Nigerian and African women. The amniotic fluid index (AFI) is one of the parameters used to assess fetal well-being and predict perinatal outcomes.
