随机方法(请说明由何人用什么方法产生随机序列):

根据专业统计软件产生的分组随机号。由一位不参与内镜室麻醉的独立的研究人员利用spss软件生成2个节段的随机数字表。

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

A grouping random number generated by professional statistical software. An independent investigator who was not involved in colonoscopy anesthesia generates a two-segment random number table by SPSS software.

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:

对患者行脑氧监测后,由一名不参与研究的第三方对病人的脑氧情况做连续记录,并将监护显示器摆放在施盲麻醉医生无法看到的位置,施盲麻醉医生对病人进行常规麻醉管理而不根据脑氧饱和度指标的变化进行相关干预。双盲。

Blinding:

After the patient underwent cerebral oxygen monitoring, the patient 's cerebral oxygen was continuously recorded by a third party not involved in the study, and the cerebral oxygenation monitoring display was placed in a position that was not visible to the blind anesthesiologist. The blind anesthesiologist performed routine anesthesia management on the patients, and did not intervene according to the changes of cerebral oxygen saturation index. Double blinded.
