This prospective study was done at Department of Obstetrics and Gynecology, Manipal College of Medical Sciences, Pokhara, Nepal to identify effectiveness of NST in detecting high risk fetus thus preventing perinatal morbidity and mortality. The cohort of 125 pregnant mothers from 37 completed weeks to 42 weeks irrespective of risk factors, were subjected to NST for 20 minutes and extended to 40 minutes to avoid fetal sleep cycle. NST was categorized into Cat I, II and III according to NICHD. Fetal distress, meconium stained liquor was higher in Cat III group. There was more intervention in Cat II and Cat III group. Total number of patients who underwent LSCS was 51. Most common indication for LSCS (53%) was for fetal distress out of which 85% had NST of Cat II (37%) and Cat III (48%). For detecting high risk fetus, NST is a simple screening procedure and is helpful in decreasing perinatal morbidity and mortality.
