Abstract Fetal NST is a simple noninvasive test performed over 28 weeks of gestation during pregnancy. Antepartum evaluation of fetus at risk for damage or death in uterus remains major challenge in modern obstetrics. NST is a noninvasive easily performed, interpreted and readily accepted by the patient. It contains – baseline heart rate, beat to beat variability of FHR, presence or absence of accelerations, early accelerations, late accelerations and variable accelerations. FHR device, Doppler ultrasound transducer, Tocodynameter, Event marker were used in fetal assessment. 50 pregnant patients were included having single fetus pregnancy with gestational age more than 30 weeks, hypertensive disorders of pregnancy, intrauterine growth retardation, post dates, liquor abnormalities and BOH. The patients having gestational age less than 30 weeks, ante partum haemorrhage, eclampsia, multiple pregnancy, ruptured membranes, congenital anomalies, and intrauterine death were excluded from study. NST was performed in all cases with CTG and recording of fetal heart rate, fetal movement and uterine contractions were noted. The fetus was stimulated for 20 minutes externally and activity was noted. It was observed that PIH (28%) and post dates (32%) are the risk factors. Majority of patients were primigravida (60%). The last NST results were with fetal outcome. Amongst NST reactive cases (33) meconium stained, Apgar score less than 7. Among non-reactive cases (74%) meconium stained. Apgar score less than 7 (75%) required ICU admissions.
