随机方法(请说明由何人用什么方法产生随机序列):

使用计算机生成的随机数字列表将产妇1:1分配为两组,A=对照组,B=实验组,每20例为一个区组,共8个区组。根据入分娩中心时间,第1至第20名受试者形成第一个区组,第21至40名受试者形成第二个区组,以此类推。使用不透明的密封信封实现分配隐藏;一名未参与数据收集的麻醉医师在硬膜外麻醉导管固定后将产妇进行分组

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

The parturients were randomly allocated into two groups in a 1:1 ratio using a computer-generated random number list. Group A represented the control group, while Group B represented the experimental group. Each block consisted of 20 cases, with a total of 8 blocks. Subjects were grouped based on their arrival time at the delivery center, with the first to twentieth subjects comprising the first ward, the twenty-first to fortieth subjects comprising the second ward, and so forth. Group A remained supine immediately after the initial bolus, while Group B maintained a left-lateral tilt position for the first 30 minutes. Opaque sealed envelopes were utilized to ensure distribution concealment. An anesthesiologist, who was not involved in data collection, categorized the parturients following the placement of the epidural anesthesia catheter and programmed the analgesic pump.

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:

使用不透明的密封信封实现分配隐藏;一名未参与数据收集的麻醉医师在硬膜外麻醉导管固定后将产妇进行分组。所有病例均由另一名一麻醉医生进行评估、观察和记录,数据由一名未参与的实验的研究者收集。

Blinding:

Opaque sealed envelopes were utilized to ensure distribution concealment. An anesthesiologist, who was not involved in data collection, categorized the parturients following the placement of the epidural anesthesia catheter and programmed the analgesic pump. Evaluation, observation, and recording of all cases were conducted by the another anesthesiologist, with data collection performed by a researcher not involved in the experiment.
