是否公开试验完成后的统计结果:

Calculated Results after the Study Completed public access:

公开/Public

盲法:

本研究采用盲法设计。试验药物准备完成后,由另一名麻醉医生负责实施麻醉干预、麻醉诱导及术中麻醉管理。在整个研究过程中,患者不知晓分组情况;负责术后评估的研究人员对分组情况完全不知情;实施麻醉的医师不知晓患者具体分组;负责数据记录的人员与药物准备人员相互分离,从而确保所有参与人员在研究全过程中均维持盲态状态。

Blinding:

This study employed a blinded design. After the study medications had been prepared, a different anesthesiologist was responsible for administering the anesthetic intervention, anesthesia induction, and intraoperative anesthetic management. Throughout the study, patients were unaware of their group assignments; the investigators responsible for postoperative assessment were fully blinded to group allocation; the anesthesiologists performing anesthesia were unaware of the patients’ specific group assignments; and the personnel responsible for data recording were separate from those preparing the study medications, thereby ensuring that all study personnel remained blinded throughout the trial.

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC:

本研究采用病例记录表(CRF)进行数据采集,由经过培训的研究人员负责填写。数据录入与管理采用 Excel,进行双人独立录入与核查,确保数据准确性与完整性。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

Data were collected using case report forms (CRFs) and completed by trained research personnel. Data entry and management were performed using Excel, with double data entry and cross-checking by two independent researchers to ensure the accuracy and completeness of the data.
