干预措施:

Interventions:

组别:

瑞玛组

样本量:

116

Group:

Remimazolam group

Sample size:

干预措施:

在诱导期静脉注射阿芬太尼 7 μg/kg,静推 10 s 以上,30 s 后缓慢静脉注射苯磺酸瑞马唑仑 0.2 mg/kg,缓慢输注 1 min;从诱导开始每 15 min 追加阿芬太尼 2.5 μg/kg,每 10 min 或当术中受试者出现体动、明显的吞咽动作等情况,追加苯磺酸瑞马唑仑 2.5 mg(静推 10 s),直至恢复平稳;两次给药间隔(下次开始给药时间 - 上次给药结束时间)需 >= 2 min,最多允许追加 4 次。

干预措施代码:

Intervention:

During the induction period, intravenous injection of alfentanil 7 μg/kg should be administered, pushed over more than 10 seconds. After 30 seconds, slowly inject remimazolam besylate 0.2 mg/kg intravenously, with a slow infusion over 1 minute. From the beginning of induction, add alfentanil 2.5 μg/kg every 15 minutes. Add remimazolam besylate 2.5 mg (push over 10 seconds) every 10 minutes or when the subject shows movements or obvious swallowing actions during surgery, until a stable state is restored. The interval between two doses (time to start the next dose - end time of the previous dose) must be >= 2 minutes, with a maximum of 4 additional doses allowed.

Intervention code:

组别:

丙泊酚组

样本量:

116

Group:

Propofol group

Sample size:

干预措施:

在诱导期缓慢静脉注射阿芬太尼7 μg/kg,静推10 s 以上,30 s 后静脉缓慢推注丙泊酚注射液 1-1.5 mg/kg,缓慢输注30s;从诱导开始每15 min 追加阿芬太尼 2.5 μg/kg,每 10 min 或当术中患者出现体动、明显的吞咽动作等情况时,追加丙泊酚 0.2mg/kg(静推 10s)直至恢复平稳;两次给药间隔(下次开始给药时间-上次给药结束时间)需≥2 min,最多允许追加 4 次。

干预措施代码:

Intervention:

During the induction period, administer a slow intravenous injection of alfentanil at 7 μg/kg, pushing over more than 10 seconds. After 30 seconds, slowly inject propofol injection intravenously at 1-1.5 mg/kg, infusing slowly over 30 seconds. From the start of induction, supplement alfentanil at 2.5 μg/kg every 15 minutes; additionally, give propofol at 0.2 mg/kg (push over 10 seconds) every 10 minutes or when the patient shows movements during surgery or noticeable swallowing actions, until stabilization is achieved. The interval between two doses (the start time of the next dose minus the end time of the previous dose) must be ≥2 minutes, with a maximum of 4 additional doses allowed.
