Night shift work is common in hospitals to assure continuous care. This practice, however, induces difficulties due to changes in the sleep/awake cycle of hospital workers. The aims of the present study were to validate actigraphy in comparison with polysomnography for sleep evaluation and to assess nurses' adaptation to sleep/wake cycles when on a permanent night shift schedule. Actigraphy and ambulatory polysomnography were performed in fifteen night shift nurses employed in hospital on a full time basis, during their work and their rest periods. Our first findings showed that actigraphy gave reliable results compared with polysomnography in evaluation of total sleep time. In addition, it was found that seven of the nurses exhibited, during their work periods, an approximately five-hour delay in the acrophase of their rest/activity rhythm compared with their rest periods. In contrast, five other nurses whose acrophase did not change between work and rest periods, exhibited sleep episodes of more than 100 minutes duration at work. These results confirm data in the literature and show that some nurses cannot adjust the circadian rhythm of their inner biological clock to their nocturnal schedules. Actigraphy seems to be an efficient, low cost and easy method for measuring total sleep time as well as for assessing the inability of nurses to adapt to permanent night shift work.
医院中夜班工作很常见，以确保持续护理。然而，这种做法会因医院工作人员睡眠/清醒周期的变化而引发困难。本研究的目的是将活动记录仪与多导睡眠图进行比较，以验证其在睡眠评估中的有效性，并评估护士在长期夜班排班时对睡眠/清醒周期的适应性。对15名全职受雇于医院的夜班护士在工作和休息期间进行了活动记录仪监测和动态多导睡眠图监测。我们的初步研究结果表明，在总睡眠时间评估方面，活动记录仪与多导睡眠图相比给出了可靠的结果。此外，还发现7名护士在工作期间与休息期间相比，其休息/活动节律的峰值相位延迟了约5小时。相比之下，另外5名护士的峰值相位在工作和休息期间没有变化，但在工作时出现了持续超过100分钟的睡眠时段。这些结果证实了文献中的数据，并表明一些护士无法将其内在生物钟的昼夜节律调整到夜间工作时间表。活动记录仪似乎是一种有效、低成本且简便的方法，可用于测量总睡眠时间以及评估护士无法适应长期夜班工作的情况。
