随机方法(请说明由何人用什么方法产生随机序列):

统计学家使用Excel 2016 (Microsoft, Redmond, WA, USA)编写随机答案列表,并使用计算机生成的随机答案列表进行有偏硬币上下序贯分配,研究助理根据该清单为下一名产妇提供舒芬太尼剂量。将初始间隔时间设定为60 min。根据前一例患者的BCUD反应确定后一例患者的间隔时间,可增加或减少5 min。如果前一名产妇需要PCEA或补救镇痛,则下一名产妇的间隔时间缩短5分钟。如果前一名产妇在研究完成前不需要PCEA或补救镇痛,则下一名产妇保持相同的间隔时间(概率为0.89)或间隔时间延长5分钟(概率为0.11)。

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

The biased coin up-and-down sequential allocation was carried out using a computer-generated list of random responses prepared by our statistician using Excel 2016 (Microsoft, Redmond, WA, USA). A research assistant used this list to provide the sufentanil dose for the next parturient. The initial interval time was set at 60 min. Interval time for the subsequent subject was determined according to the responses of the previous subject using the BCUD with a possible increment or decrement of 5 min. If the previous parturient required PCEA or rescue analgesia, the interval time was shorten 5 min in the subsequent parturient. If the previous parturient did not required PCEA or rescue analgesia, the next parturient would receive either the same interval time (probability of 0.89) or the interval time was extended by 5 minutes (probability of 0.11).
