研究目的:

本研究拟探讨在宫腔镜日间手术患者中复合瑞马唑仑时阿芬太尼和瑞芬太尼成功插入喉罩的半数有效量(ED50)和95%有效量(ED95),在此基础上验证与瑞芬太尼相比,阿芬太尼对宫腔镜日间手术患者可以提供非劣效出院时间,并观察苏醒时间、自主呼吸恢复、喉罩拔除时间、PACU停留时间、下床活动时间和VAS评分等恢复期指标及相关不良反应,以期为临床安全、合理用药提供参考。  

Objectives of Study:

This study was to investigate the half effective dose (ED50) and 95% effective dose (ED95) of alfentanil and remifentanil combined with remimazolam when laryngeal mask was successfully inserted in patients undergoing hysteroscopic day surgery . On this basis, it was to be verified that compared with remifentanil, alfentanil can provide non inferior discharge time for patients undergoing hysteroscopic day surgery, and recovery indicators such as recovery time, spontaneous breathing recovery, laryngeal mask removal time, PACU stay time, ambulation time and VAS score and related adverse reactions were observed, so as to provide reference for clinical safety and rational drug use.

干预措施:

阿芬太尼组 (A 组) 改良 Dixon 序贯法:预氧合 3 分钟后,依次缓慢给予苯磺酸瑞马唑仑 0.2mg/kg(静注 60 秒)和阿芬太尼(静注 30 秒,剂量根据前一位患者反应调整,首位设为 10ug/kg,增减幅度 1ug/kg)。 瑞芬太尼组 (R 组) 改良 Dixon 序贯法:预氧合 3 分钟后,使用注射泵给予瑞芬太尼(泵注 60 秒,剂量根据前一位患者反应调整,首位设为 1ug/kg,增减幅度 0.1ug/kg),并同时缓慢给予苯磺酸瑞马唑仑 0.2mg/kg(静注 60 秒)。

干预措施代码:

Intervention:

Alfentanil group (Group A) Modified Dixon sequential method: After 3 minutes of preoxygenation, remimazolam besylate 0.2 mg/kg was slowly administered intravenously over 60 seconds, followed by alfentanil intravenously over 30 seconds. The alfentanil dose was adjusted based on the previous patient's response, with the initial dose set at 10 μg/kg and an adjustment step of 1 μg/kg. Remifentanil group (Group R) Modified Dixon sequential method: After 3 minutes of preoxygenation, remifentanil was administered via infusion pump over 60 seconds, while remimazolam besylate 0.2 mg/kg was simultaneously slowly administered intravenously over 60 seconds. The remifentanil dose was adjusted based on the previous patient's response, with the initial dose set at 1 μg/kg and an adjustment step of 0.1 μg/kg.
