组别:

青年组(18~44岁)

样本量:

40

Group:

Youth group(18-44 years old)

Sample size:

干预措施:

采用改良Dixon序贯法,根据预实验结果及相关研究设定苯磺酸瑞马唑仑的初始剂量为0.20mg/kg,剂量梯度设定为0.01mg/kg。下一例受试者的瑞马唑仑剂量由上一例患者镇静情况决定,若患者给药后3min内睫毛反射消失且改良警觉/镇静量表评分降至0分视为镇静成功,则下一例患者降低一个剂量梯度,否则视为失败,下一例患者升高一个剂量梯度。正式测试从第一个交叉波开始,一直持续到第七个交叉波出现结束研究。

干预措施代码:

Intervention:

Using the improved Dixon sequential method, the initial dose of remifentanil besylate was set at 0.20mg/kg and the dose gradient was set at 0.01mg/kg based on pre experimental results and relevant studies. The dose of remifentanil for the next subject is determined by the sedation status of the previous patient. If the eyelash reflex disappears within 3 minutes after administration and the modified alertness/sedation scale score drops to 0, it is considered a successful sedation. The next patient will reduce the dose gradient by one, otherwise it will be considered a failure, and the next patient will increase the dose gradient by one. The formal testing starts from the first cross wave and continues until the appearance of the seventh cross wave, ending the study.
