Apathphysiological study of sleep disturbance in the postpartumperiod

母亲产后睡眠表现为睡眠时间较短，夜间因照顾婴儿而醒来的次数较多。根据问卷调查的回溯性研究，大多数母亲即使睡眠时间很短，也会适应产后生活。一些有睡眠问题的母亲对此并不适应。针对产后抑郁、母性忧郁、婴儿睡眠-唤醒节律自由奔跑引起的母亲睡眠障碍的病理生理学研究较少，本研究前瞻性、客观性地研究了婴儿昼夜睡眠-唤醒节律自由奔跑引起的母性忧郁和母体睡眠障碍。对12例孕晚期(33周和36周)至产后(2周、6周和12周)的母亲及其婴儿进行多导睡眠图和活动描记。受试者在参与研究前给予书面知情同意。The…研究结果如下：1、在本研究中，我们没有遇到患有母性忧郁的受试者。母亲的活动和婴儿的活动之间的同步性在适应的母亲身上表现得很强，而非适应的母亲在我们之前的母性忧郁症研究(1998)中提出了一种弱的同步。这位母亲遵循着婴儿的昼夜睡眠-觉醒节奏。与其他母亲相比，母亲在怀孕后期的昼夜睡眠-觉醒节律较长。孕晚期的母体节律被认为影响了婴儿的自由奔跑节律。3、我们成功地记录了孕妇因胎动而引起的睡眠中的微唤醒。微唤醒为研究孕妇的睡眠障碍打开了大门。4、我们成功地利用一种新开发的传感器记录了孕妇睡眠期间的胎儿运动。该系统可用于家庭长期胎动监测。该系统已申请专利。较少

Mothers' sleep in the postpartum period shows short sleep time and number of awakenings at night coming from taking care of their infants. According to retrospective studies using a questionnaire, most mothers adapt themselves to the postpartum life, even though their sleep time is short. A few mothers with sleep complaints do not adapt themselves to it. There were few pathphysiological studies on mothers' sleep disturbance in depression of the postpartum period, maternity blues, and sleep disturbance coming from free-running of infants' circadian sleep-wake rhythm.In this study, we prospectively and objectively studied sleep disturbance, especially, maternity blues and maternal sleep coming from free-running of infants' circadian sleep-wake rhythm. Polysomnographic and actigraphic recordings were made from late pregnancy (33 and 36 weeks) to postpartum (2,6 and 12 weeks) on 12 mothers and their infants. The subjects gave written informed consent before participating in the study. The … More results were as follows :1, We did not encounter subjects with maternity blues in this study. Synchronization between mothers' activity and infants' activity is strong on adapted mothers, while non-adapted mother in our previous study with maternity blues (1998) suggested a weak synchronization.2, We found one mother with her infant's free-running circadian sleep-wake rhythm. The mother followed her infant's circadian sleep-wake rhythm. The mother's circadian sleep-wake rhythm in her late pregnancy was long compared with other mothers. The maternal rhythm in late pregnancy was thought to influence her infant's free-running rhythm.3, We succeeded in recording micro-arousals during pregnant women's sleep evoked by their fetal movement. Micro-arousals open the door to studies of pregnant women's sleep disturbance.4, We succeeded in recording fetal movement by a newly developed sensor on maternal abdomens during maternal sleep. This system can be used for a long-term home monitoring of fetal movement. This system is applied for a patent. Less
