Calculated Results after the Study Completed public access:

不公开/Private

盲法:

为了保持双盲,所有试验用药将由不参与临床治疗、麻醉操作及结局评估的非盲研究人员或药师根据随机分组表进行配制,并装入外观完全一致的20 ml注射器,仅标注受试者唯一识别编号,不显示分组信息。为确保不同分组药物在外观和体积上的一致性,苯磺酸瑞马唑仑、磷丙泊酚二钠及其相应的安慰剂(0.9%氯化钠注射液)均将稀释至总容量为20 ml,所有制剂均为无色透明液体,并使用相同规格的注射器封装。注射器将在麻醉诱导前即刻由研究人员交予麻醉医生使用。所有参与临床管理、麻醉操作、数据收集及结局评估的人员,以及受试者本人,均将在整个研究过程中保持盲态,直至数据收集完成并开展最终统计分析。如因医疗紧急情况或其他正当原因需揭盲,分组信息仅限于指定的授权人员查阅,以确保研究的盲法原则得到严格遵循。

Blinding:

To maintain double-blinding, all study medications will be prepared in identical 50 ml syringes labeled only with the participant’s unique identification number, without indicating the assigned group. An unblinded pharmacist or research staff member, who is not involved in clinical care, anesthesia management, or outcome assessment, will be responsible for drug preparation based on the randomization schedule. To ensure that the appearance and volume of the study medications remain indistinguishable across all groups, remimazolam besylate, fospropofol disodium, and their corresponding placebos (normal saline) will be diluted to a total volume of 50 ml using 0.9% sodium chloride. All solutions are colorless and transparent and will be provided in identical infusion syringes. These syringes will be handed over to the attending anesthesiologist immediately prior to induction. All personnel involved in clinical management, anesthesia delivery, data collection, and outcome assessment, as well as the participants themselves, will remain blinded to the treatment allocation until the completion of data collection and final statistical analysis. In the event of a serious adverse event requiring unblinding, access to allocation information will be restricted to authorized personnel designated for emergency disclosure only.
