A psychophysiological study on a postpartum depressive state

2.在产后9 ~ 12周，当婴儿获得昼夜节律时，有两种类型的睡眠模式，即间断睡眠和非间断睡眠。中断的睡眠与产后早期的模式相似，而非中断的睡眠与非妊娠妇女的模式接近。与未怀孕妇女相比，未中断睡眠的第4阶段增加。第四阶段非中断睡眠的增加似乎是由睡眠剥夺引起的恢复性睡眠。首先，我们研究了产后适应良好的产妇夜间睡眠模式的变化。其睡眠特点如下：1.在产后1 - 6周的早期，母亲的平均总睡眠时间为322分钟，平均睡眠效率为77%。与负责喂养的妊娠晚期相比，产后睡眠开始后的清醒时间显着增加。阶段3+4和阶段 ...更多信息 REM在四个阶段（怀孕，产后第一，第三和第六周）没有变化，但第二阶段从怀孕到产后显著下降。虽然睡眠时间减少了，但他们的睡眠效率很高。在母亲的清醒和婴儿的运动之间有很强的同步性。第二，我们曾尝试对一名患有产后抑郁症的产妇进行多导睡眠图记录。但是，当病人遭受强烈的产妇忧郁症时，我们很难得到病人的同意。因此，我们改变了我们的方法，从多导睡眠图到活动图。这两个案例，都多导睡眠图和活动记录，进行了记录。其睡眠特点如下：1. 2.当婴儿出现运动时，他们不能迅速起床。这些发现不支持Karacan（1996）的假说，即产后睡眠不足可能是产生产妇忧郁症的一个因素。我们必须收集大量的案例，并需要讨论产妇忧郁的原因。这项研究表明，腕动记录仪将成为一个有用的方法来调查产妇忧郁。少

2. In the postpartum periods from nine to twelve weeks, when infants obtain their circadian rhythm, there were two types of sleep patterns, interrupted sleep and non-interrupted sleep. Interrupted sleep was similar to the ;patterns of early postpartum, while non-interrupted sleep was close to patterns of non-pregnant women. Stage 4 in non-interrupted sleep increased compared with that of non-pregnant women. Increased Stage 4 of non-interrupted sleep seemed to be a recovery sleep arising from sleep deprivation.Firstly, we studied changes in the nocturnal sleep patterns of primiparas who adapted well to the postpartum periods. Characteristics of their sleep patterns were as follows.1. In the early postpartum periods from one to six weeks, mean total sleep time of the mothers was 322 minutes, and mean sleep efficiency was 77%. Wake time after sleep onset increased significantly during the postpartum period compared with late pregnancy given responsibility for feeding. Stage 3+4 and stage … More REM did not change across the four sessions (pregnancy, first, third, and sixth postpartum weeks), but stage 2 decreased significantly from pregnancy to postpartum. The primiparas slept effectively, though their sleep time decreased. There was a strong synchronization between mothers wakefulness and their infants' movements.Secondly, we had attempted that polysomnographic recordings of a patient with a postpartum depressive state, maternity blues, were made. But it was difficult that we received the patients' consents, when they suffered strongly from maternity blues. Thus, we changed our methods from polysomnogram to actigram. The two cases, both polysomnographic and actigraphic recordings, were made. Characteristics of their sleep were as follows.1. The two patients evaluated their sleep to be poor, though their sleep patterns did not change compared with those of adapted mothers.2.They did not get up quickly, when their infants' movements occurred.These findings did not support a hypotheses of Karacan (1996) that sleep deprivation during postpartum might be a factor producing maternity blues. We must collect many cases, and nee to discuss reasons of maternity blues. This study showed that actigraphy would become a useful method to investigate patients with maternity blues. Less
