Abstract

Background: The primary goal of antenatal testing is to identify fetuses at risk of intrauterine neurologic injury or death so that these adverse outcomes can be prevented. We want to assess nonstress test (NST) results and some parameters before and after vibro-acoustic stimulation and acupressure. We did a randomized controlled clinical trial in Shahid-Beheshti Hospital in Isfahan in 2011.

Materials and methods: A total of 64 pregnant women (32-36 weeks) in prenatal care unit were selected for vibro-acoustic stimulation (n = 32) and acupressure (n = 32) during the second NST. The statistical processing was performed by descriptive, paired t-test, analysis of variance (ANOVA), chi-square, and McNemar test through SPSS version 20.

Results: The mean baseline fetal heart rate (FHR) in vibro-acoustic and acupressure groups before and after stimulations did not differ significantly. The mean time of first acceleration in vibro-acoustic group was decreased after stimulations significantly, but in the acupressure group it did not differ statistically. The numbers of accelerations in both groups did not differ significantly before and after stimulation. The mean time of second acceleration in the vibro-acoustic group was 6.7 min before stimulation and 3.9 min after stimulation. This decrease was significant. The mean time of second acceleration after stimulation was lower than before significantly in the acupressure group. The frequency of reactive NST was same in both groups, before and after stimulation.

Conclusion: Vibro-acoustic stimulation and acupressure of acupoint BL67 did not change FHR parameters but they could decrease the time of reactive result of NST.
