A psychophysiological study on a postpartum depressive state

2.在产后9~12周，婴儿达到昼夜节律时，有两种睡眠模式，即间断睡眠和非间断睡眠。间断睡眠与产后早期的睡眠模式相似，而不间断睡眠的模式与未怀孕妇女的模式相近。未被打断睡眠的阶段4比未怀孕的女性增加。不间断睡眠增加的阶段4似乎是由于睡眠剥夺而产生的恢复睡眠。首先，我们研究了适应产后阶段的初产妇夜间睡眠模式的变化。他们的睡眠模式的特点如下：1。产后早期1~6周，产妇平均总睡眠时间为322分钟，平均睡眠效率为77%。与孕晚期相比，产后开始入睡后的觉醒时间显着增加，负责喂养。阶段3+4和阶段…在四个阶段(怀孕、产后第一周、第三周和第六周)，更多的REM没有改变，但阶段2从怀孕到产后显著减少。虽然初产妇的睡眠时间减少，但他们的睡眠效率很高。母亲的清醒和婴儿的活动之间有很强的同步性。第二，我们试图对一名患有产后抑郁症的患者进行多导睡眠图记录。但我们很难得到患者的同意，因为他们患有严重的母性忧郁症。因此，我们改变了我们的方法，从多导睡眠图到活动图。这两个病例，都是多导睡眠图和活动记录仪记录的。他们的睡眠特点如下：1。这两名患者认为他们的睡眠质量很差，尽管与适应环境的母亲相比，他们的睡眠模式并没有改变。2.当他们的婴儿发生运动时，他们起床不快。这些发现不支持Karacan(1996)的假设，即产后睡眠不足可能是导致产妇忧郁的一个因素。我们必须收集许多病例，并需要讨论孕妇忧郁原因。这项研究表明，活动描记将成为调查患有母性忧郁症的患者的有用方法。较少

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
