随机方法(请说明由何人用什么方法产生随机序列):

非随机。 我们采用偏置硬币设计(biased coin design, BCD)对非肥胖患者和肥胖患者进行了平行研究。简而言之,我们选择了K有序剂量水平,各剂量水平之间的固定增量为 0.1 mg/kg。由研究人员自行决定,两组患者均接受其中一个K有序剂量水平,初始剂量为 0.2 mg/kg。前一名患者的反应决定了后续患者的剂量水平。例如,如果观察到前一名患者的反应为阴性,则同一分配组的下一名患者接受的瑞马唑仑剂量将在前一剂量的基础上以预定的增量(0.1mg/kg)递增。如果观察到阳性反应,同组的下一位患者将有95%的概率接受相同剂量或以5%的概率接受较低剂量的瑞马唑仑,剂量较上一次减少 0.1mg/kg。对瑞马唑仑的阳性反应定义为瑞马唑仑3分钟泵注完时RSS ≥4。根据我们的经验,RSS 4分是儿童麻醉诱导中令人满意的镇静水平,既能顺利与父母分离,又能建立静脉通路。此外,RSS 4分或5分已被公认为儿童患者进行安全有效的程序镇静的深度。

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

Non-randomised. We conducted a parallel study of non-obese and obese patients using a biased coin design (BCD). Briefly, we chose K-ordered dose levels with fixed increments of 0.1 mg/kg between dose levels.At the discretion of the investigators, patients in both groups received one of the K-ordered dose levels with an initial dose of 0.2 mg/kg.The response of the previous patient determined the dose level of the subsequent patient. For example, if a negative response is observed in the previous patient, the next patient in the same allocation group will receive a dose of remazolam in predetermined increments (0.1 mg/kg) from the previous dose. If a positive response is observed, the next patient in the same group will have a 95% probability of receiving the same dose or, with a 5% probability, a lower dose of remazolam, reduced by 0.1 mg/kg from the previous dose.A positive response to remazolam is defined as an RSS ≥4 at the end of the 3-minute pumping of remazolam.In our experience, an RSS score of 4 is a satisfactory level of sedation for the induction of anaesthesia in children that both smooth separation from parents and establishment of intravenous access. In addition, an RSS score of 4 or 5 has been recognised as the depth at which safe and effective procedural sedation can be performed in paediatric patients.
