Objective: NST is an effective tool frequently used in surveillance of High risk pregnancy group. The aim of this study is to evaluate the role of NST for routine surveillance of low risk pregnant patients admitted in labor room so that we can detect high risk fetus in low risk pregnant woman as early as possible to decrease perinatal morbidity and mortality.
Method: This is a prospective longitudinal study at GMERS Medical College Sola, Ahmedabad, Gujarat, India, Department of obstetrics and gynecology from April 2014 to September 2014. This study included 350 low risk pregnant mothers with labor pain after 37 completed weeks who were subjected to NST for 20 minutes.
Result: Fetal distress, meconium stained liquor and caesarean section rates were higher in non-reactive (NR) and equivocal (E) NST than in the reactive (R) NST group. Perinatal morbidity in Reactive, Equivocal and Non-Reactive was 2.4%, 18.36% & 44.44% respectively.
Conclusion: This study suggest that NST is good screening procedure for detecting high risk fetus in obvious low risk mothers .The probability of adverse outcome like meconium stained liquor and poor APGAR score increases with E and NR results.
