Keywords: amniotic fluid index, pregnancy, reference ranges, Nigeriaġ. Using 5th and 95th percentile as lower and upper limits of normal, reference ranges for each gestational age was ascertained.Ĭonclusion: Third trimester reference ranges of AFI is established and this can be used as a guide for evaluation of amniotic fluid volume in this obstetric population. Amniotic fluid volume was highest at 28 weeks, stabilized and plateau between 37-39 weeks and declined after 40 weeks’ gestation. The AFI reference range for the study population was 13.6-24.6 cm. Results: Mean AFI among the entire study population was 18.1☓.1 cm (range of 10.4-26.8 cm) while the mean AFI for preterm and term pregnancies were 18.5☒.6 cm and 17.8☓.5 cm respectively. Mean, ranges, 5th, 10th, 50th, 90th and 95th percentiles for each gestational age were calculated using SPSS version 20 (IBM, Armonk, NY, USA). The uterine cavity was divided into four quadrants and using real-time ultrasonography, the vertical diameter of the largest pool of amniotic fluid was measured and summation of the values gave the amniotic fluid index (AFI). Fifty women each were recruited at two-weekly interval from 28-36 weeks’ gestation and then weekly up to 41 weeks’ gestation. Materials and Methods: This was a prospective cross-sectional study among 500 healthy pregnant women. Objectives: To ascertain the normal values of amniotic fluid index in third trimester among Nigerian women with uncomplicated singleton pregnancies in Jos, Nigeria. ![]()
