正常人新环境中睡眠第一晚效应研究

First-night effect on polysomnogram in normal subjects

本研究旨在观察睡眠实验室的睡眠环境和实验操作对正常人新环境中第一晚睡眠的影响。描记１９例正常人在新环境中连续两晚的多导睡眠图。结果发现，第一晚的睡眠潜伏期延长，睡眠效率下降，深睡期和快动眼睡眠期减少。提示正常人的第一晚效应是存在的。

Objective:To study the effect of environment and investigations on polysomnogram in the first night of sleep study. Method:Whole-night sleep polysomnographic recordings were obtained for two consecutive days in nineteen normal subjects.Data from the first and second day were compared. Results: The first night recordings showed longer sleep latency,decreased sleep efficiency and shorter delta and REM sleep. Discussion:First-night effect should be included in the analysis of sleep recordings.
