“首夜效应”(FNE)是在多导睡眠图(PSG)研究的第一个晚上观察到的睡眠结构的改变。目前尚不清楚 FNE 是否反映了对设备、睡眠环境或两者的适应。此外,某些患者群体,例如患有创伤后应激障碍(PTSD)的患者,可能表现出更大的高度依赖于环境的适应效应。我们在一项横断面研究中评估了患有 PTSD 的参与者和健康对照者的 FNE,该研究包括在家中和医院进行 PSG 测试。与我们的预期相反,创伤后应激障碍组在这两种情况下都没有表现出适应效果。只有分配到“医院优先”条件的对照组在研究的第一晚与第二天晚上的总睡眠时间显着减少。结果表明,FNE与对医院环境和记录设备的结合的适应有关。
The "first night effect” (FNE) is the alteration of sleep architecture observed on the first night of polysomnographic (PSG) studies. It is unclear whether the FNE reflects adaptation to the equipment, sleeping environment, or both. Moreover, it is possible that certain patient populations, such as those with posttraumatic stress disorder (PTSD), demonstrate greater adaptation effects that are highly context dependent. We assessed FNE in participants with PTSD and healthy controls in a cross sectional study consisting of PSG testing at home and in the hospital. Contrary to our expectations, the PTSD group showed no adaptation effects in either setting. Only the control group assigned to the “hospital first” condition showed significant decreases in total sleep time on night one versus night two of the study. The results suggest that the FNE is related to adaptation to the combination of the hospital environment and the recording equipment.
