研究目的:

主要目的: 探讨术前老年营养风险指数(GNRI)水平对瑞玛唑仑联合瑞芬太尼用于老年无痛胃肠镜检查时镇静有效剂量(ED??、ED??)的影响。 次要目的: 比较不同GNRI水平老年患者在接受瑞玛唑仑联合瑞芬太尼镇静时的起效时间、苏醒时间及不良反应发生率,评估GNRI在老年患者镇静剂量个体化中的预测价值。  

Objectives of Study:

Primary Objective:To investigate the effect of preoperative Geriatric Nutritional Risk Index (GNRI) levels on the effective sedative doses (ED50 and ED95) of remimazolam combined with remifentanil in elderly patients undergoing painless gastrointestinal endoscopy.Secondary Objectives:To compare sedation onset time, recovery time, and the incidence of adverse events among elderly patients with different GNRI levels receiving remimazolam combined with remifentanil, and to evaluate the predictive value of GNRI for individualized sedation strategies in elderly patients.
