OBJECTIVE
The purpose of this study was to examine the effect of vibroacoustic stimulation during low fetal heart rate (FHR) variability.
METHODS
FHR was analyzed 30 min before and 30 min after computerized vibroacoustic stimulation using the Oxford Sonicaid system 8000. The study comprised 32 healthy pregnant women with low antepartum FHR variability. The significance of difference of the median values was examined using Wilcoxon's matched-pairs signed-ranks test.
RESULTS
Vibroacoustic stimulation of the fetus during low FHR variability evoked a significant increase in the number of accelerations (> 10 bpm) and an increase in long- and short-term variation.
CONCLUSION
Our findings indicate that vibroacoustic stimulation during low FHR variability produces an abrupt change from a quiet to an active fetal state.
目的
本研究旨在探讨在胎儿心率（FHR）变异性较低时进行振动声学刺激的效果。
方法
使用牛津Sonicaid系统8000，在计算机化振动声学刺激前30分钟和后30分钟对FHR进行分析。该研究包括32名产前FHR变异性较低的健康孕妇。使用Wilcoxon配对符号秩检验来检验中位数差异的显著性。
结果
在FHR变异性较低时对胎儿进行振动声学刺激，可使加速次数（>10次/分钟）显著增加，并使长期和短期变异性增加。
结论
我们的研究结果表明，在FHR变异性较低时进行振动声学刺激会使胎儿状态从安静突然转变为活跃。
