随机方法(请说明由何人用什么方法产生随机序列):

由一名独立研究人员进行区组随机化,以1:1:1:1的比例将招募的参与者分配到DEX和麻醉深度的四种组合中。

Randomization Procedure (please state who generates the random number sequence and by what method):

An independent researcher performs the blocked randomization to assign recruited participants to one of four combinations of dexmedetomidine and anesthesia depth in a 1:1:1:1 allocation.

是否公开试验完成后的统计结果:

Calculated Results after the Study Completed public access:

公开/Public

盲法:

由于麻醉技术之间的差异,麻醉实施者不能对麻醉深度的分组设盲,但对右美使用设盲。他们不会参与患者招募、数据收集或统计分析。患者、外科医生、术后医护人员、结果评估者和负责最终分析的统计学家将对分组不知情。

Blinding:

The anesthesia providers cannot be blinded to the group allocation of anesthesia depth due to the differences between the anesthesia techniques, but they will be blinded to the group allocation of DEX. They will not participate in patient recruitment, data collection, or statistical analysis. Patients, surgeons, postoperative care providers, outcome assessors, and the statistician responsible for final analyses will be masked to the group allocation.
