背景：胎儿运动引起的孕妇睡眠障碍是众所周知的。胎动被认为是胎儿健康的一个指标。然而，由于没有一种简单可靠的方法来记录胎儿的运动，对孕妇的剧烈扰动和胎儿健康的心理生理学研究尚未开展。目的：为了解决这些方法上的问题，我们开发了一种新的静电传感器，可以检测胎儿运动的加速度。方法与结果：实验一：验证了我们的胎动记录系统的可靠性。32名孕妇（孕19 - 39周）被要求躺在床上约1小时，当她们感觉到胎儿运动时按下一个按钮作为主观标记。我们使用Medilog记录仪同时记录了母亲腹部的多导睡眠图和胎儿运动。根据记录的胎儿运动信号和主观母体标记之间的时间，经流行率调整的偏差调整的一致性kappa平均值为0.75。实验二：在妊娠第33周和第36周，我们使用我们的传感器同时记录了7名孕妇在家中通宵睡眠时的多导睡眠图和胎儿运动。我们成功地记录了胎儿运动引起的母体微觉醒。33周微觉醒次数的平均值略大于36周。结论：产妇主观指标与胎儿运动具有较高的一致性。我们的记录系统使用新的传感器可以用于家庭监测胎儿运动。2008爱思唯尔爱尔兰有限公司版权所有。
Background: Pregnant women's sleep disturbance due to fetal movement is well known. Fetal movement is thought to be an index of fetal well-being. However, as there has never been a way to easily and reliably record fetal movement, psychophysiological studies of pregnant women's steep disturbance and fetal well-being have not been done.Aims: To solve these methodological issues, we developed a new sensor with electrostatic capacity that can pick up acceleration of fetal movement.Methods and results: Experiment 1: We verified the reliability of our fetal movement recording system. Thirty-two pregnant women (from 19 to 39 weeks of gestation) were asked to lie down on a bed for about 1 h and to press a button as a subjective marker when they felt fetal movement. We simultaneously recorded maternal polysomnograms and fetal movement from the mothers' abdomens using a Medilog recorder. The mean of prevalence-adjusted bias-adjusted kappa for agreements, based on time between fetal movement signals recorded and subjective maternal markers, was substantial at 0.75. Experiment II: We recorded seven pregnant women's polysomnograms and fetal movement simultaneously during all-night steep at home using our sensor during weeks 33 and 36 of gestation. We succeeded in recording maternal micro-arousals evoked by fetal movement. The mean value of the number of micro-arousals at 33 weeks was slightly larger than that at 36 weeks.Conclusions: There was a high agreement between subjective maternal markers and fetal movement. Our recording system using the new sensor can be used for home monitoring of fetal movement. (C) 2008 Elsevier Ireland Ltd. All rights reserved.
