Role of Non-stress Test and Vibroacoustic Stimulation Test in Prediction of Perinatal Outcome in High-risk Pregnancies. International Journal of Scientific Study. 2020 Apr; 8(1): 84-882321-595X2321-6379http://imsear.searo.who.int/handle/123456789/209418Objectives: The aim of the study was to evaluate the fetal well being by non-stress-test (NST) and vibroacoustic stimulationtest (VAST) in high-risk pregnancies, to assess the perinatal outcome, to study the ability of the VAST to convert a false-positive(non-reactive) NST to a reactive one.Materials and Methods: Atotal of 100 pregnant women with >32 weeks gestation having certain high-risk factors were subjectedto NST and if NST came out to be non-reactive, vibroacoustic stimulation was given with artificial larynx. Perinatal outcome wasassessed by various parameters (meconium stained liquor, Apgar score at 5 min, neonatal intensive care units admission). Theresults were analyzed by Chi-square test to find the association between NST, VAST results, and perinatal outcome.Results: It was found that VAST reduced the number of false-positive results by 31%. As compared to NST, VAST had lesssensitivity (78.05% vs. 80.48%), and better specificity (95.08% vs. 83.61%), better positive predictive valve (91.43% vs. 82.35%)in predicting perinatal outcome.Conclusion: The addition of vibroacoustic stimulation to the NST reduced significantly the number of non-reactive tests. NSTwhen reactive does represents a satisfactory indicator for fetal well-being but non-reactive test needs further evaluation beforeany active intervention.Non-stress testPerinatal outcomeVibroacoustic stimulation testRole of Non-stress Test and Vibroacoustic Stimulation Test in Prediction of Perinatal Outcome in High-risk PregnanciesJournal ArticleIndiaResident Doctor, Department of Obstetrics and Gynaecology, Government Medical College, Amritsar, Punjab, IndiaLecturer, Department of Obstetrics and Gyanecology, Government Medical College, Amritsar, Punjab, IndiaProfessor and Head, Department of Obstetrics and Gynaecology, Government Medical College, Amritsar, Punjab, India
