研究目的: |
1.主要目的:本研究旨在系统表征与比较老年(>=65岁,<85岁)与非老年(>=18岁,<65岁)患者在瑞马唑仑靶控输注期间,前额叶脑电图(EEG)特征的差异。 2.次要目的:旨在定量描绘瑞马唑仑效应室浓度与关键EEG参数(如频谱边缘频率等)之间的量效关系,并确定其在不同年龄段患者中的药效学特征。 3.探索性目的:探索临床衰弱状态(采用临床衰弱量表评分界定“脆弱”与“非脆弱”老年患者)对瑞马唑仑所致EEG动态变化的调节作用,为该高危亚群的精准麻醉提供初步神经生理学依据。 |

|
Objectives of Study: |
1. Primary Objective:This study aims to systematically characterize and compare the differences in prefrontal electroencephalographic (EEG) features between elderly (>=65 years,<85 years) and non-elderly (>=18 years,<65 years) patients during remimazolam target-controlled infusion. 2. Secondary Objective:It seeks to quantitatively delineate the dose-response relationship between remimazolam effect-site concentrations and key EEG parameters (such as spectral edge frequency), and to determine their pharmacodynamic profiles in patients of different age groups. 3. Exploratory Objective:This study aims to explore the moderating effect of clinical frailty status (defining "frail" versus "non-frail" elderly patients using the Clinical Frailty Scale score) on the dynamic EEG changes induced by remimazolam. The goal is to provide preliminary neurophysiological evidence for precision anesthesia in this high-risk subpopulation. |
