研究目的:

本研究拟通过前瞻性PK/PD临床研究,验证既有瑞马唑仑群体PK/PD模型在老年血管介入程序性镇静患者中的适用性,并进行必要的局部参数优化。在评估瑞马唑仑复合舒芬太尼用于程序性镇静镇痛临床效果的同时,初步探索年龄、ASA分级、白蛋白及舒芬太尼用量等临床变量对瑞马唑仑PK/PD特征的影响,并评价模型对术中镇静水平的预测性能。  

Objectives of Study:

This study aims to validate the applicability of an existing population pharmacokinetic/pharmacodynamic (PK/PD) model of remimazolam in elderly patients undergoing interventional procedural sedation through a prospective PK/PD clinical study, and to perform necessary local parameter refinement. While evaluating the clinical efficacy of remimazolam combined with sufentanil for procedural sedation and analgesia, this study will preliminarily explore the effects of clinical variables such as age, ASA physical status classification, albumin level, and sufentanil dosage on the pharmacokinetic and pharmacodynamic characteristics of remimazolam, and assess the predictive performance of the model for intraoperative sedation depth.
