研究目的:

本研究采用偏性掷币上下序贯设计,在以瑞马唑仑为基础镇静的老年无痛胃肠镜检查患者中,估计瑞芬太尼达到胃镜置入90%无阳性反应概率的ED90,并同时估计其ED50及95%CI,进一步描述该给药策略的安全性和恢复特征,为优化老年患者无痛胃肠镜检查的镇静镇痛方案提供依据。  

Objectives of Study:

This study adopts a biased-coin up-and-down sequential design to estimate the ED90 of remifentanil for achieving a 90% probability of no positive response to gastroscope insertion in elderly patients undergoing painless gastrointestinal endoscopy under remimazolam-based sedation, while also estimating its ED50 and 95% confidence interval (CI). The safety and recovery profile of this dosing strategy will also be characterized to provide evidence for optimizing sedation–analgesia regimens for painless gastrointestinal endoscopy in elderly patients.

组别:

样本量:

Group:

Single-Arm Sequential Study

Sample size:

干预措施:

瑞马唑仑 (Remimazolam) 0.3 mg/kg 静脉推注诱导,随后动态调整瑞芬太尼 (Remifentanil) 剂量(初始 0.10 μg/kg,步长 0.02 μg/kg,范围 0–0.40 μg/kg)进行剂量探索;若出现镇静不足或阳性反应,按方案追加瑞马唑仑(最大总剂量 0.5 mg/kg)或启用丙泊酚补救。 本研究不采用传统平行分组随机化,而采用偏性掷币上下序贯分配。首例受试者瑞芬太尼初始剂量为 0.10 μg/kg;后续剂量根据前一例受试者胃镜置入反应按预设规则调整:阳性反应则下一例增加 0.02 μg/kg,阴性反应则通过偏性掷币随机决定下一例剂量,以 1/9 概率下调 0.02 μg/kg、8/9 概率维持原剂量。

干预措施代码:

Intervention:

Remimazolam 0.3 mg/kg intravenous bolus induction, followed by dynamic remifentanil dose adjustment (initial 0.10 μg/kg, increment 0.02 μg/kg, range 0–0.40 μg/kg) for dose exploration; if sedation inadequacy or positive response occurs, remimazolam is supplemented per protocol (maximum total dose 0.5 mg/kg) or propofol rescue is initiated. This study does not use conventional parallel-group randomization; instead, it employs a biased-coin up-and-down sequential allocation design. The initial remifentanil dose for the first participant is set at 0.10 μg/kg. Subsequent doses are adjusted according to the previous participant’s response to gastroscope insertion based on the prespecified rule: if a positive response occurs, the dose for the next participant is increased by 0.02 μg/kg; if no positive response occurs, the dose for the next participant is determined by biased-coin randomization, with a 1/9 probability of decreasing by 0.02 μg/kg and an 8/9 probability of remaining unchanged.
