干预措施:

Interventions:

组别:

瑞马唑仑自控镇静组

样本量:

60

Group:

Remimazolam patient-controlled sedation group

Sample size:

干预措施:

待麻醉平面稳定(T8~10水平)后手术开始时给药,瑞马唑仑配制成0.5mg/ml,给予瑞马唑仑自控镇静(负荷量2ml+背景量1.5ml+单次量0.5ml,锁定时间60s)。

干预措施代码:

Intervention:

After the anesthesia plane stabilizes (at the T8-T10 level), the medication is administered at the beginning of the surgery. Remimazolam is prepared at a concentration of 0.5mg/ml. Remimazolam is administered for patient-controlled sedation (loading dose of 2ml + background dose of 1.5ml + single dose of 0.5ml, with a lockout time of 60 seconds).

Intervention code:

组别:

瑞马唑仑常规镇静组

样本量:

60

Group:

Remifentanil conventional sedation group

Sample size:

干预措施:

待麻醉平面稳定(T8~10水平)后手术开始时给药,瑞马唑仑配制成0.5mg/ml,给予瑞马唑仑常规镇静(负荷量0.05-0.1mg/kg+维持量0.1-0.3mg/(kg·h)),负荷量泵注1min。

干预措施代码:

Intervention:

After the anesthesia plane stabilizes (at the T8-T10 level), the medication is administered at the beginning of the surgery. Remimazolam is prepared at a concentration of 0.5mg/ml. The conventional sedation with remimazolam is given (loading dose of 0.05-0.1mg/kg + maintenance dose of 0.1-0.3mg/(kg·h)), and the loading dose is pumped in for 1 minute.
