尽管许多研究详细介绍了护士轮班工作对健康、疲劳、嗜睡或医疗事故造成的后果，但尚未进行任何研究试图将与轮班工作相关的嗜睡和疲劳与注意力表现的影响分开。这项试点研究的目的是 (A) 调查 8 小时快速轮班对护士疲劳和困倦的影响，以及 (B) 这些因素如何影响他们的精神运动表现。根据早上-下午-晚上的轮班顺序，选择 14 名护士进行受试者内横断面研究，将其作为疲劳、困倦和精神运动警戒任务 (PVT) 表现的函数进行比较。随后，受试者内协方差分析 (ANCOVA) 评估了当嗜睡的影响得到控制时，观察到的轮班之间的差异是否持续存在。我们的结果清楚地表明，夜班与显着的困倦和疲劳以及 PVT 表现恶化有关。正如假设的那样，ANCOVA 表明，当睡意的影响得到控制时，这些差异就会消失。结果表明，与依赖于睡意的白班相比，夜间的精神运动表现较低。因此，尽量减少夜班后果的干预措施应考虑减少嗜睡。
Although many studies have detailed the consequences of shift work in nurses concerning health, fatigue, sleepiness, or medical errors, no study has been carried out trying to disentangle the contribution of sleepiness and fatigue associated to shift work from the attentional performance. The aim of this pilot study is (A) to investigate the effects of an 8-h rapidly rotating shift on fatigue and sleepiness among staff nurses and (B) how these factors affect their psychomotor performance. Fourteen nurses were selected for a within-subject cross-sectional study according to this sequence of shifts: morning-afternoon-night, which were compared as function of tiredness, sleepiness, and performance at the Psychomotor Vigilance Task (PVT). Subsequently, a within-subject Analysis of Covariance (ANCOVA) evaluated if the observed differences between shifts persist when the contribution of sleepiness is controlled. Our results clearly indicate that night shifts are associated with significant greater sleepiness and tiredness, and worsened performance at the PVT. As hypothesized, ANCOVA showed that these differences disappear when the contribution of sleepiness is controlled. Results point to a lower psychomotor performance in night compared to day shifts that depends on sleepiness. Hence, interventions to minimize the consequences of the night shift should consider a reduction of sleepiness.
