Abstract

Objectives: to evaluate the association between stress, fatigue and salivary cortisol levels in nurses working in emergency units (EU) and surgical units (SU).

Methods: cross-sectional study conducted in two university hospitals with participation of 66 nurses. The Nursing Stress Inventory and the Fatigue Assessment Scale were applied, and saliva samples were obtained to determine cortisol concentration.

Results: high levels of stress and fatigue were observed in 50.8% and 46% of the professionals, respectively. Nurses in EU had higher levels of stress and fatigue and lower secretion of salivary cortisol during the work shift compared to nurses in the SU, without statistical significance. Cortisol secretion in the morning period was correlated with fatigue (ρ=0.25 and p=0.04).

Conclusions: the results suggest a dysregulation of the hypothalamic-pituitary-adrenal axis in nurses from the EU and a significant correlation between fatigue and cortisol secretion in the morning period.

重症监护病房护士的压力和疲劳及其与唾液皮质醇的关系

目的：评估急诊科（EU）和外科（SU）护士的压力、疲劳和唾液皮质醇水平之间的关系。方法：对两所大学附属医院66名护士进行横断面研究。采用护理压力量表和疲劳评定量表，取唾液样本测定皮质醇浓度。结果：50.8%和46%的专业人员存在高水平的压力和疲劳。欧盟护士在轮班期间的压力和疲劳水平高于SU护士，唾液皮质醇分泌水平较低，但无统计学意义。早晨皮质醇分泌量与疲劳程度相关（ρ=0.25, p=0.04）。结论：结果提示欧盟护士的下丘脑-垂体-肾上腺轴失调，早间疲劳与皮质醇分泌显著相关。
