Study phase:

研究设计:

随机平行对照 

Study design:

Parallel 

研究目的:

1.采用序贯法确定环泊酚、丙泊酚使患者意识消失的半数有效剂量(ED50)。 2.在等效麻醉剂量(ED50)下,严格排除复合药物干扰,以灌注指数(PI)为核心指标,比较环泊酚与丙泊酚的外周血管舒张效应及用药后血流动力学稳定性,明确两种药物本身的血管活性差异。  

Objectives of Study:

1.The sequential method was adopted to determine the median effective dose (ED₅₀) of ciprofol and propofol for inducing loss of consciousness in patients. 2.At equipotent anesthetic doses (ED₅₀), interference from combined medications was strictly excluded. With perfusion index (PI) as the primary indicator, we compared the peripheral vasodilatory effects and post-administration hemodynamic stability between ciprofol and propofol, so as to clarify the differences in vasoactive properties of the two drugs.

30

Group:

Group A: Ciprofol group in Phase 1

Sample size:

干预措施:

环泊酚起始剂量为 0.4 mg/kg,于30秒内匀速静脉推注。剂量调整梯度:环泊酚组剂量梯度为 0.05 mg/kg,当每组序列中出现第7个阴阳性转折点(意识消失/未消失反应交替的节点)时,终止该组试验。

干预措施代码:

Intervention:

The initial dose of ciprofol was 0.4 mg/kg, administered as a uniform intravenous bolus over 30 seconds. The dose step for the ciprofol group was 0.05 mg/kg. The trial was terminated once the 7th positive-negative crossover point (alternating responses of loss and retention of consciousness) appeared in the sequence of each group.

30

Group:

Group B: Propofol group in Phase 1

Sample size:

干预措施:

丙泊酚起始剂量为 1.5 mg/kg,于30秒内匀速静脉推注。剂量调整梯度:丙泊酚组剂量梯度为 0.25 mg/kg,当每组序列中出现第7个阴阳性转折点(意识消失/未消失反应交替的节点)时,终止该组试验。

干预措施代码:

Intervention:

The initial dose of propofol was 1.5 mg/kg, administered via intravenous bolus at a constant rate over 30 seconds. The dose step for the propofol group was 0.25 mg/kg. The trial of each group was terminated when the 7th positive-negative crossover point (alternating responses of loss and retention of consciousness) occurred in the sequence.

第二阶段环泊酚组(C 组)

样本量:

60

Group:

Group C: Ciprofol group in Phase 2

Sample size:

干预措施:

两组均采用第一阶段测得的 ED50 作为剂量,30 秒匀速静脉注射。记录给药后 1 min、2 min、3 min 的 PI、MAP、HR。给药 3 min 后呼叫患者,评估苏醒状态。

干预措施代码:

Intervention:

Both groups were given the ED50 determined in Phase1 via uniform intravenous injection over 30 seconds. PI, MAP and HR were recorded at 1 min, 2 min and 3 min after administration. Patients were called 3 minutes after dosing to assess the recovery status.
