随机方法(请说明由何人用什么方法产生随机序列):

通过计算机生成随机数字的方法将受试者随机分为三组,A组:右美托咪定+维生素C组;B组:右美托咪定组;C组:对照组。

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

Subjects were randomly assigned to three groups using computer-generated random numbers: Group A: Dexmedetomidine + Vitamin C group; Group B: Dexmedetomidine group; Group C: Control group.

是否公开试验完成后的统计结果:

Calculated Results after the Study Completed public access:

不公开/Private

盲法:

主治麻醉医师知道具体的分组。评估者及统计者不知道研究对象具体分组。一位研究人员负责随机分组并准备研究药物,右美托咪定稀释到50ml生理盐水,维生素C稀释到100ml生理盐 水,两种药物均是无色无味。

Blinding:

The attending anesthesiologist is aware of the specific group assignments. The assessors and statistician are blinded to the group allocation of participants. One researcher is responsible for randomization and preparing the study drugs: dexmedetomidine is diluted in 50 mL of normal saline, and vitamin C is diluted in 100 mL of normal saline; both solutions are colorless and odorless.
