随机方法(请说明由何人用什么方法产生随机序列):

本实验拟采用完全随机设计方法,将每个组的编号都写在一张卡片上,并将卡片密封于不透光的信封里。患者进入手术室时护士随机抽取一个信封,根据抽出的卡片来给患者分组。

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

This experiment plans to adopt a completely random design method, write the number of each group on a card, and seal the card in an opaque envelope. When the patient enters the operating room, the nurse randomly draws an envelope and groups the patients according to the cards drawn.
