A Study on Fetal Wellbeing through the Non-Reactive Non-Stress Test in the Patients Referred to Motazedi Hospital, Kermanshah, Iran

Since 1975, the non-stres stest (NST) has been applying as a first step to assess fetal well being. Over past decades, antepartum fetal heart rate testing has become an integral part in high-risk pregnancy management. During this time, the contraction stress test has given way to the non-stress test for primary fetal surveillance due to its proven reliability and its low false negative rate [1-4]. The main feature of normality to interprete the testis FHR accelerations, i.e., reactive tracing. Accelerations, which resemble aspike-like or transitory increase above baseline as a result of sympathetic nervous system stimulation, have been shown to be reassuring both antepartum and intrapartum [1,2,5-7], and indicate a non-acidotic fetus [1,8].
