Six house officers at two Stockholm hospitals were subjected to 41 h of continuous ambulatory recording of EEG and EOG in connection with night call duty, and to 24 h in connection with normal day work. The results showed that night call duty greatly interfered with sleep, reducing its duration to 4 h. The reduction mainly affected sleep stages 2 and REM. SWS was not affected, whereas EEG spectral power density in the 0.5-7.9 Hz band was suppressed. During subsequent time off, napping and night sleep increased total sleep length above baseline levels. It was concluded that night call duty of the present type causes considerable sleep loss.
斯德哥尔摩两家医院的六名住院医生在值夜班期间接受了41小时的脑电图（EEG）和眼电图（EOG）连续动态记录，在正常日间工作期间接受了24小时的记录。结果显示，值夜班极大地干扰了睡眠，使其时长缩短至4小时。这种缩短主要影响睡眠的第2阶段和快速眼动（REM）阶段。慢波睡眠（SWS）未受影响，而0.5 - 7.9赫兹频段的脑电图频谱功率密度受到抑制。在随后的休息时间里，小憩和夜间睡眠使总睡眠时间增加到基线水平以上。得出的结论是，当前这种类型的值夜班导致了相当程度的睡眠缺失。
