Acoustic stimulation of the fetus has been suggested to improve the efficiency of antepartum fetal heart rate testing.
The objective of this review was to assess the merits or adverse effects of the use of fetal vibroacoustic stimulation in conjunction with tests of fetal wellbeing.
We searched the Cochrane Pregnancy and Childbirth Group trials register. Date of last search: October 2000.
All published and unpublished randomized controlled trials assessing the merits of the use of fetal vibroacoustic stimulation in conjunction with tests of fetal wellbeing.
Both reviewers independently extracted data and assessed trial quality. Authors of published and unpublished trials were contacted for further information.
A total of seven trials with a total of 4325 participants were included. Fetal vibroacoustic stimulation reduced the incidence of non-reactive antenatal cardiotocography test (odds ratio (OR) 0.61, 95% confidence interval (CI) 0.49-0.75) and reduced the overall mean cardiotocography testing time (weighted mean difference (WMD) -4.55 minutes, 95% CI -5.96 minutes to -3.14 minutes). Vibroacoustic stimulation evoked more than mock stimulation when used in conjunction with fetal heart rate testing (OR 0.08, 95% CI 0.06-0.12).
REVIEWER'S CONCLUSIONS: Vibroacoustic stimulation offers benefits by decreasing the incidence of non-reactive cardiotocography and reducing the testing time. Further randomized trials should be encouraged to determine not only the optimum intensity, frequency, duration and position of the vibroacoustic stimulation, but also to evaluate the efficacy, predictive reliability, safety and perinatal outcome of these stimuli with cardiotocography and other tests of fetal wellbeing.
有人提出对胎儿进行声刺激可提高产前胎儿心率检测的效率。
本综述的目的是评估使用胎儿振动声刺激结合胎儿健康测试的优点或不良影响。
我们检索了Cochrane妊娠与分娩组试验注册库。最后检索日期：2000年10月。
所有已发表和未发表的随机对照试验，评估使用胎儿振动声刺激结合胎儿健康测试的优点。
两位综述作者独立提取数据并评估试验质量。已发表和未发表试验的作者被联系以获取更多信息。
共纳入7项试验，总计4325名参与者。胎儿振动声刺激降低了无反应型产前胎心监护试验的发生率（比值比（OR）0.61，95%置信区间（CI）0.49 - 0.75），并缩短了总体平均胎心监护测试时间（加权平均差（WMD）-4.55分钟，95% CI -5.96分钟至-3.14分钟）。当与胎儿心率测试联合使用时，振动声刺激比模拟刺激诱发的反应更多（OR 0.08，95% CI 0.06 - 0.12）。
振动声刺激通过降低无反应型胎心监护的发生率和缩短测试时间带来益处。应鼓励进一步进行随机试验，以确定振动声刺激的最佳强度、频率、持续时间和位置，同时评估这些刺激与胎心监护及其他胎儿健康测试的有效性、预测可靠性、安全性和围产期结局。
