随机方法(请说明由何人用什么方法产生随机序列):

阶梯楔形随机对照试验(Stepped-Wedge RCT)特有的分组方法,具体设计如下: 分组方法核心特征 1. 随机单元 聚类随机:以 手术间(Operating Room) 为随机单元(非患者个体) 群组数量:4个手术间(群组1~4) 2. 分组逻辑 组别 定义 分配方式 C组(常规组) 仅接受常规监测(SpO₂+EtCO₂),无BIS预警 所有手术间初始均为C组 T组(干预组) 常规监测 + BIS实时预警系统(ΔZ↓≥15%或θ↑≥10%触发报警) 按随机时间点阶梯式激活 由独立统计师使用SAS PROC PLAN生成手术间激活时序序列

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

tepped-Wedge Cluster Randomized Controlled Trial (SW-CRCT) - Specific Group Allocation Method Core Design Features: Unit of Randomization: Cluster randomization: The Operating Room (OR) serves as the unit of randomization/cluster (not individual patients). Number of Clusters: 4 Operating Rooms (Clusters 1 to 4). Group Allocation Logic: Group Definition Allocation Method C Group (Control Group) Receives routine monitoring only (SpO₂ + EtCO₂). No BIS alerts. All ORs are initially assigned to the C Group. T Group (Intervention Group) Receives routine monitoring + real-time BIS alert system (Alarm triggered by ΔZ ↓ ≥15% or θ ↑ ≥10%). Generated by an independent statistician using SAS PROC PLAN.
