Abstract :

The Non Stress Test (NST) has become a useful tool in antenatal surveillance because of its wide applicability, ease of performance and relatively low cost. In a country like India with large population and limited resources, the antepartum surveillance modalities have to be cost effective. Thus NST has a major role to play in such a situation because of practical advantage that it offers in terms of simplicity and cost effectiveness. This study was done to analyse the interpretations of non–reassuring fetal heart rate patterns seen on NST and their implications in evaluating mode of delivery and perinatal outcome. The study was carried out in 172 pregnant females attending the antenatal clinic at Prakash Institute of Medical Sciences, Urun–Islampur and Holy Family Hospital, Bandra, Mumbai. All pregnant women above 37 weeks of gestation attending the Obstetrics Outpatient Department were included in the study and they were subjected to a weekly NST tracing till delivery. Antenatal NST results were used to compare the mode of delivery and perinatal outcome. Following outcomes were observed: 1.Operative interference in form of LSCS was more common in cases with a non–reactive NST as compared to reactive NST (61.1%vs. 33.8%). 2.Meconium stained liquor was more common amongst non–reactive NST cases (83.3% vs. 36.8%) 3.NICU admission rate was high among cases with non–reactive NST (63.9% vs. 7.4%) To conclude, non–reactive NST displayed significant association with operative interference in form of LSCS and also with poor perinatal outcome.
