It is clear that external vibroacoustic stimulation produces remarkable changes in fetal heart rate and fetal movement patterns which are related to changes in fetal behavior. The clinical significance of these effects on human fetuses has been addressed by many authors in series of small number of patients involved. There is an obvious lack of uniformity in the different protocols used to determine the predictive value of fetal acoustic stimulation in the assessment of fetal health. Current knowledge of the normal responses of healthy human fetuses to acoustic stimulation and the limitations of this type of testing should be taken into account to determine more accurately the negative and positive predictive value for fetal outcome.
显然,外部振动声学刺激会使胎儿心率和胎儿运动模式产生显著变化,这些变化与胎儿行为的改变有关。许多作者在涉及少数患者的系列研究中探讨了这些影响对人类胎儿的临床意义。在用于确定胎儿声学刺激在评估胎儿健康方面的预测价值的不同方案中,明显缺乏一致性。应考虑到目前关于健康人类胎儿对声学刺激的正常反应的知识以及这类测试的局限性,以便更准确地确定胎儿结局的阴性和阳性预测价值。
