随机方法(请说明由何人用什么方法产生随机序列):

由一名不参与本研究的助手采用MedCalc18.2.1软件创建了一组随机编码序列,按编码序列随机将80例单胎妊娠产妇分为4组,每组20人(即0.0625%罗哌卡因+0.4μg/ml右美托咪定6ml组,8ml组,10ml组,12ml组)。

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

A random coding sequence was created by an assistant who was not involved in this study using MedCalc18.2.1 software, and 80 women with single pregnancy were randomly divided into 4 groups with 20 persons per group according to the coding sequence (i.e. 0.0625% ropivacaine +0.4μg/ml dexmedetomidine 6ml, 8ml, 10ml, 12ml).

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:

双盲。一名不参与后续实验的助手无菌操作配置硬膜外分娩镇痛药物;具体负责实施分娩镇痛的麻醉医师,实验数据记录者等对局麻药配方,镇痛泵参数设置等均不知情。

Blinding:

Double blinded. An assistant who did not participate in the follow-up experiment was given epidural labor analgesics during aseptic operation; The specific anesthesiologist responsible for the implementation of labor analgesia, the experimental data recorder, etc. did not know the local anesthetic formula, the analgesia pump parameter setting, etc.
