Abstract :
Background: Antepartum evaluation of the fetus at risk for damage or death in utero remains a major
challenge in modern obstetrics. Freeman & Lee (1975) 1 and colleagues introduced the non-stress test to
describe acceleration of fetal heart rate is a sign of fetal health in response to fetal movement.
Aims: Role of Non stress test in antepartum fetal surveillance and perinatal outcome in high risk pregnancy.
To prove the efficacy of NST as an effective tool for evaluation of fetal well-being. To decrease perinatal
morbidity and mortality.
Materials and Methods: Hospital based prospective study. 50 pregnant women with high risk factors as
study group and 50 healthy pregnant women as control group were randomly selected from period of July
2015 to December 2015 in the department of Obst & Gynae Dr. S. N. Medical college Jodhpur. Non stress
test performed and results were analysed.
Results: Non stress test as screening test for antenatal fetal surveillance has high specificity and high
negative predictive value.
Conclusion: The ideal test for fetal reserve should be safe, inexpensive, readily available, quickly exerted
and devoid of either false positive or false negative results. As yet no such test exists which is perfect, still
NST has been shown to be most acceptable modality for evaluating the fetus in utero.
