Abstract
NST is a test that records graphically the fetal heart activity and uterine activity continuously through uterine quiescence and contraction with foetal movement. It is not only simple and inexpensive; it is also noninvasive and is easily performed and interpreted. Women with high risk pregnancy, non-reactive NST/CTG and women with low risk pregnancy, non-reactive NST/CTG enrolled into the study from 34 weeks of gestation admitted in labour room. Positive predictive value of non-reactive NST test is 85%/non-reactive CTG 48% for caesarean sections done for fetal distress. With non-reactive NST/CTG trace false positive rate to predict perinatal outcome was 73% and 79% respectively; this could probably be the result of an early intervention and hence improving the perinatal outcome
