随机方法(请说明由何人用什么方法产生随机序列):

随机分组结果装入不透明信封,信封上标注入组序号,由专人保管,合格的患者按照入组序号,开启相应信封获取分组结果,依据随机分组结果进行相应止血措施,并随访止血及相关信息;患者和信息采集者不清楚分组结果。

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

The random grouping results were placed in opaque envelopes, with the enrollment numbers marked on the envelopes. They were kept by designated personnel. Qualified patients opened the corresponding envelopes according to the enrollment numbers to obtain the grouping results. Based on the random grouping results, corresponding hemostasis measures were taken, and follow-up was conducted on hemostasis and related information. Patients and information collectors were not clear about the grouping results.
