随机方法(请说明由何人用什么方法产生随机序列):

采用区组随机化方法进行分组。由不参与患者招募、麻醉管理与结果评估的独立研究人员,使用统计软件生成随机序列。采用动态区组长度(例如,在4和6之间随机选择),按1:1的比例将合格受试者分配至右美托咪定组(D组)与生理盐水对照组(C组)。

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

Block randomization was used for grouping. Independent researchers who were not involved in patient recruitment, anesthesia management and outcome evaluation generated random sequences using statistical software. The eligible subjects were assigned to dexmedetomidine group (Group D) and normal saline control group (Group C) in a 1:1 ratio using the dynamic zone length (for example, randomly selected between 4 and 6).

盲法:

麻醉护士不参与手术过程、术后评估或数据收集工作。在研究分析完成前,所有入组患者、麻醉医师及结果评估员均不会获知分配情况。

Blinding:

Anesthesia nurses were not involved in the surgical process, postoperative assessment, or data collection. All enrolled patients, anesthesiologists, and outcome assessors will not be informed of the allocation until the study analysis is completed.
