Summary:INTRODUCTION: Several studies show that fetal sleeping periods can lead to falsely non- reactive test, therefore increasing the risk of unnecessary obstetric intervention. Attempt to arouse the fetus while in sleeping state or in rest activity cycle include a change in maternal position, physical activity, maternal glucose ingestion, sound stimulation, light stimulation and manual fetal manipulation. However the only stimuli that have consistently evoked response in normal fetus are acoustic and vibrotactile ones. AIMS & OBJECTIVES: 1. To compare and evaluate the role of nonstress test and vibro acoustic stimulation test on the perinatal outcome. 2. To evaluate vibro acoustic stimulation test as a screening test for early intrapartum fetal monitoring. MATERIAL AND METHODS: This study was done at department of OBGY, NIMS, hospital Jaipur. It included 100 women with high risk pregnancies above 34 weeks of gestation. Fetal monitor was used for nonstress test, and acoustic stimulator by teksonic instrument with sound pressure 80-85db for vibro acoustic stimulation test. It is a cross sectional study. OBSERVATION & RESULTS: High risk pregnant women showed (75%) 75 cases positive test which included (Reactive nst with reactive vast and also with reactive vast over non-reactive nst) out of which 62 cases (82.6%) were with favourable perinatal outcome and 13cases (17.3%) with unfavourable perinatal outcome. CONCLUSION: Result showed that in the high risk pregnancies after vibroacoustic stimulation test were significantly associated with favourable perinatal outcome. KEYWORDS: Vibroacoustic stimulation test as adjunct to non-stress test for antepartum fetal wellbeing.
