概括
麻醉深度监测器,双光谱指数 (BIS) 和大脑状态指数 (CSI),显示在催眠惚期间显著下降. 这些电生理学措施可以通过追踪惚深度和诱导功效来帮助催眠研究.
科学领域:
- 神经科学是一个神经科学.
- 心理学 心理学 心理学
背景情况:
- 催眠惚涉及神经生理变化,需要客观监测与主观报告一起.
- 现有的基于脑电图 (EEG) 的麻醉深度监测器在非药物诱导的状态,如催眠等方面面临着挑战.
研究的目的:
- 调查麻醉深度监测器 (BIS和CSI) 是否对催眠惚的诱导和维持做出反应.
- 评估这些监视器是否能区分具有不同催眠暗示能力的个体.
主要方法:
- 56名志愿者接受了标准化的催眠方案 (哈佛集团催眠易感度量表).
- 双光谱指数 (BIS) 和大脑状态指数 (CSI) 被监测,以及主观的催眠深度评分.
- 根据测试成绩,参与者被分为高和低暗示性组.
主要成果:
- 在催眠诱导后,BIS和CSI分数显著下降,并在整个惚状态中保持较低.
- 在高和低可暗示性参与者之间没有观察到BIS或CSI反应的显著差异.
- 主观的催眠深度评分跟随监测读数的类似趋势,但BIS/CSI值和主观深度评分之间没有直接的相关性.
结论:
- 麻醉深度监测器 (BIS,CSI) 对催眠惚状态做出反应,表明意识的变化.
- 虽然催眠的特异性需要进一步研究,但这些监视器在催眠研究中可能是有价值的工具,用于评估诱导疗效和惚障碍,不包括药物影响或睡眠.

Various sedation levels offer significant advantages in facilitating procedural interventions for patients undergoing medical or invasive surgical procedures. These levels span from anxiolysis to general anesthesia, providing a spectrum of sedative effects to cater to specific patient needs. Anxiolysis reduces anxiety and is achieved through minimal sedation, enabling patients to remain awake and responsive while feeling more at ease during the procedure. This level can benefit minor...

Altered states of consciousness represent significant deviations from one's normal mental state. These deviations can range from subtle changes in awareness to profound transformations in perception, thought processes, and sensory experiences. Altered states of consciousness can be triggered by various factors, including drug use, meditation, hypnosis, illness, or even intense fatigue.
