Comparative study of efficacy of fetal Admission test alone and non-stress test done antenatally with fetal Admission test to evaluate fetal outcome

Abstract

Aim. Current study evaluated the efficacy of fetal admission test alone and nonstress test (NST) antenatally with fetal admission test in both low and high risk pregnant in relation to fetal outcome to decrease the fetal morbidity and mortality. Methods and material. Study included 240 pregnant women after 34 weeks of pregnancy who were categorized into low and high risk groups. The fetal outcome following Antenatal NST and Admission test studied based on Apgar score of <7 at 5 minutes, Meconium stained liquor, NICU requirement, and mortality. Result. Apgar score <7 at 5 min seen in 8 babies (13.33%), meconium stained liquor in 14(23.33%) and NICU admission in 11 (18.33%) cases in whom both antenatal NST and fetal admission tests were done together. Apgar score <7 at 5 min seen in 14 (23.33%) babies, meconium stained liquor in 18 (30%) and NICU admission in 19 (31.66%) cases in whom only admission test was done. The Antenatal NST for antenatal fetal surveillance shows 96.88% of specificity, 29.17% of sensitivity, 70% of positive predictive value (PPV) and 84.55% of negative predictive value (NPV). The admission test for intrapartum fetal distress shows 99.38% of specificity, 32.91% sensitivity, 75.12% NPV and 96.3% PPV. Both NST and fetal admission test done together significantly decreased the incidence of fetal distress as early intervention was taken to prevent further fetal compromise in high-risk pregnant. NST strongly correlate with admission test result in high-risk pregnant. Conclusion. NST and fetal admission test in high risk pregnant helps for early detection of fetal distress and help to take necessary intervention to improve fetal outcome.
