长时间反复的持续清醒对轮班工作者，特别是实习医生来说是一个严重的问题。在一个真实的临床环境中，我们调查是否采取长时间的午睡可以抵消急性睡眠剥夺的负面影响，对执行技能的residents.METHODS五十四名实习生在医学院的大学拉奎拉（意大利）参加了这项研究。32名上夜班的参与者被分配到唤醒或午睡组（WG，NG）。剩下的22名参与者，谁保持正常的昼夜工作时间，被分配到控制睡眠组（SG）。每个参与者在连续3天进行的三个会话中执行任务切换和进行/不进行任务，以提供基线和实验（夜班后[WG和NG]）数据以及在家中正常夜间睡眠（SG）后和恢复后（在家中过夜后）的数据。因变量进行混合模型方差分析（ANOVA）。结果夜班后，SG和NG的参与者表现出更好的执行速度比WG的参与者在任务切换。此外，工作组的参与者表现出较低的准确性在整个研究protocol相比，SG和NG participator.CONCLUSIONS采取长时间的午睡被证明是有效的改善恶化的执行技能，伴随夜班工作的实习生。这一发现提出了两个令人困惑的问题，即夜间小睡应该多长时间以及何时最好，以支持维持巩固新执行技能的有效过程。
OBJECTIVES Long and repeated periods of sustained wakefulness constitute a serious problem for shift workers in general and for medical interns in particular. In a real clinical setting, we investigated whether taking a long nap can counteract the negative consequences of acute sleep deprivation on executive skills in residents.METHODS Fifty-four interns at the Faculty of Medicine of the University of L'Aquila (Italy) participated in the study. Thirty-two participants who worked the night shift were assigned to a wake or nap group (WG, NG). The remaining 22 participants, who maintained regular diurnal working hours, were assigned to a control sleep group (SG). Each participant performed task switching and go/no-go tasks in three sessions, carried out on 3 consecutive days, to provide baseline and experimental (after the night shift [WG and NG]) data and data subsequent to having a normal night's sleep at home (SG) and subsequent to recovery (after a night's sleep at home). The dependent variables were submitted to a mixed-model analysis of variance (ANOVA).RESULTS After the night shift, SG and NG participants demonstrated better performance speed at task switching than WG participants. Moreover, WG participants showed lower accuracy throughout the study protocol compared with SG and NG participants.CONCLUSIONS Taking a long nap proved to be effective in ameliorating the deterioration in executive skills that accompanies night shift-working in interns. This finding raises the two entwined issues of how long a nocturnal nap should be and when it should best occur in order to support the maintenance of an effective process of consolidation of new executive skills.
