This randomized controlled trial (RCT) was undertaken to evaluate the effect of vibroacoustic stimulation (VAS) on the fetal heart rate tracing, mode of delivery and perinatal outcomes, when cardiotocographs (CTG) showed non-reassuring features during labour. In this RCT, 60 women beyond 30 weeks' gestation in labour having non reassuring CTG for 20 min were recruited in either study group (VAS group) or control group (non-VAS group). Women in the study group received VAS for 3 sec up to 3 occasions at an interval of 1 to 3 min while the control group received no VAS. There were significant improvement of baseline variability and acceleration in both VAS and control group during second 20 min (P<0.001). Although these improvements were more evident in VAS group, the difference between the two groups were not statistically significant (P>0.05). However, in VAS group, there was 3 min less testing time required to achieve reassuring CTG features (2.6 versus 5.6 min), and a tendency to have less cesarean delivery (60% versus 55.2%; p>0.05). Perinatal outcomes were similar in both groups. There is a trend toward less number of caesarean section in VAS group, probably because of early and more acquisition of reassuring CTG features. Therefore, this study suggests that VAS is potentially beneficial in women with suspicious CTG. Considering the procedure simple, safe and less expensive, it would be prudent to use VAS during CTG monitoring, especially in low resource countries, where facilities for fetal blood sampling is not widely available.

“…Sood atul Kumar et al also reported comparable results in terms of perinatal deaths with sensitivity 100%, specificity 96.2%, positive predictive value 20%, negative predictive value 100%, and accuracy 96.2%. 1 VAST has increased in use over recent years as various researchers have found it comparable, cheaper, faster and less invasive than other tests of fetal well-being.…”

“…Intrapartum fetal assessment is aimed at identifying the fetus, that may be either already compromised in early labour or at an increased risk of compromise during late labour. 1 An early identification of such foetuses may help in instituting close surveillance to reduce perinatal morbidity and mortality. This may also help in utilising the available resource optimally in resource-constraint setting.…”

“…This may also help in utilising the available resource optimally in resource-constraint setting. 1 Various tests for intrapartum fetal assessments has been used like fetal kick count, non-stress test, biophysical profile, umbilical artery doppler and vibroacoustic stimulation. A good antenatal test will help to act judiciously by not waiting too long and thus will prevent adverse perinatal outcome.…”

Background: Present study was undertaken to evaluate the effectiveness and safety of intrapartum modified biophysical profile along with vibroacoustic stimulation test in the assessment of fetal well-being compared with modified biophysical profile for women with a singleton pregnancy.Methods: This prospective study was carried out on a group of pregnant women of gestational age more than 35 weeks attending the labour room of obstetrics and gynecological department of Patna medical college and hospital, from October 2013 to October 2015. A total 220 pregnant women were selected and randomly divided into two groups, 110 women were given modified biophysical profile and 110 were underwent modified biophysical profile with VAST.Results: Among 110 women, who underwent modified biophysical profile, 80(72.7%) showed reactive response and 30(27.3%) showed non-reactive response. A total 110 women, in whom modified biophysical profile was combined with VAST, 100(91%) showed reactive response and 10 (9%) showed non-reactive response. Statistical comparison for predicting perinatal mortality was done. Modified biophysical profile with VAST had a high sensitivity (100% vs. 80%), specificity (92.5% vs. 75.2%), negative predictive value (100% vs. 98.7%) and positive predictive value (20% vs. 13.3%) as compared to modified biophysical profile. Test accuracy for predicting perinatal mortality was more than mBPP (92.7% vs.75.4%).Conclusions: Addition of VAST in place of NST in modified biophysical profile has high specificity & positive predictive value, shortens the testing time.

Beat-to-Beat Variability During Auditory Music in Fetus and Mother: A Clinical Trial

Background: Non-stress test is the most widely used test to assess fetal status. The presence of beat-to-beat variability is reassuring while its absence is not reassuring. Methods: In this single-blind clinical trial, 213 pregnant women with gestational age of 37 -41 weeks were randomly allocated into three groups (auditory intervention for mother, auditory intervention for fetus, and control), each containing 71 subjects. The data were analyzed using one-way ANOVA followed by Tukey HSD test and Kruskal-Wallis test. In addition, paired t-test was used to compare each group before and after the intervention. Results:The results showed a significant difference among the three groups regarding beat-to-beat variability of fetal heart rate in the second 10 minutes of the test (P = 0.006). Besides, the results of Tukey HSD test indicated that this difference was significant between the control group and auditory intervention for mother group (P = 0.004). Moreover, the results of t-test showed a significant difference in beat-to-beat variability of fetal heart rate between the first and the second 10 minutes of the test in both groups of auditory intervention for mother (P < 0.001) and for fetus (P < 0.001). Conclusions:Since beat-to-beat variability of the fetal heart rate is indicator of fetal health, music intervention can be used to increase the number of accelerations and reduce false positive results in NST.
