Night shift work is an essential part of hospital nursing, but it can disrupt nurses' biological rhythms, leading to sleep deprivation and fatigue, affecting cognitive function and cerebral oxygenation. This impact may be exacerbated in sub-plateau regions due to environmental factors. Existing research on the effects of night shifts on the cognitive function and cerebral oxygenation of pediatric intensive care unit (PICU) nurses in sub-plateau areas needs to be more extensive. This study utilized near-infrared spectroscopy (NIRS) to measure 100 PICU nurses working in the sub-plateau area of Kunming, China, before and after their night shifts. The measured indicators included baseline cerebral oxygen saturation, verbal fluency task performance, and anxiety scores. After the night shift, the nurses' baseline cerebral oxygen saturation significantly decreased (t(99)=-5.23, p < 0.001), their verbal fluency task performance significantly declined (t(99)=-6.42, p < 0.001), and their anxiety scores significantly increased (t(99) = 1.96, p = 0.05). Multiple regression analysis indicated that baseline cerebral oxygen saturation was an independent predictor of verbal fluency and anxiety scores. Night shift work may lead to sleep deprivation and fatigue among PICU nurses in sub-plateau areas, impairing their cognitive function and cerebral oxygenation. The environmental characteristics of sub-plateau areas may exacerbate these effects. It is recommended that nurses' sleep and mental health be considered when scheduling night shifts and that practical measures be implemented to mitigate the adverse cognitive effects of night shifts.
夜班工作是医院护理工作的重要组成部分，但它可能会扰乱护士的生物节律，导致睡眠不足和疲劳，影响认知功能和脑氧合。由于环境因素，在亚高原地区这种影响可能会加剧。目前关于亚高原地区儿科重症监护病房（PICU）护士夜班对其认知功能和脑氧合影响的研究还需要更加广泛。本研究利用近红外光谱（NIRS）对中国昆明亚高原地区的100名PICU护士在夜班前后进行了测量。测量指标包括基线脑氧饱和度、语言流畅性任务表现和焦虑评分。夜班后，护士的基线脑氧饱和度显著下降（t(99)= -5.23，p < 0.001），语言流畅性任务表现显著下降（t(99)= -6.42，p < 0.001），焦虑评分显著增加（t(99) = 1.96，p = 0.05）。多元回归分析表明，基线脑氧饱和度是语言流畅性和焦虑评分的独立预测因素。夜班工作可能导致亚高原地区PICU护士睡眠不足和疲劳，损害其认知功能和脑氧合。亚高原地区的环境特征可能会加剧这些影响。建议在安排夜班时考虑护士的睡眠和心理健康，并采取切实可行的措施减轻夜班对认知的不利影响。
