随机方法(请说明由何人用什么方法产生随机序列): |
由与本试验执行数据管理统计分析无关的生物统计学家,在计算机上用R 4.3 统计软件包,按试验组与对照组 1:1 的比例进行随机大小的区组随机化。将产生的随机数字底表密封于连续编号的随机信封,保管于研究协调员处。 |
||||||||
|
Randomization Procedure (please state who generates the random number sequence and by what method): |
A biostatistician independent of trial implementation, data management and statistical analysis performed block randomization with a 1:1 allocation ratio between the experimental group and control group using the R 4.3 software package on a computer. The generated random number list was sealed in consecutively numbered random envelopes and kept by the study coordinator. |

盲法: |
本研究采用三盲(参与者、临床实施者及结局评估者均不知情)的随机、对照、平行分组设计,以确保干预措施的实施和结果测量均不受预期偏倚影响。随机分配结果仅由独立的非临床研究人员掌握,所有参与临床照护、数据收集、随访或统计分析的人员均保持盲态。为实现严格的盲法,所有用于干预的药物(包括术中输注及术后 PCIA 药物)均由独立药学团队依据随机化编号统一制备,所有注射器、输液袋、输注泵和 PCIA 装置均使用外观一致、标签一致的容器,并仅标注随机编号而不显示任何药物名称、剂量或组别信息。药物的体积、外观、颜色及包装均保持一致,使两组参与者在任何给药时点均无法从药物或操作流程辨识所属组别。 |
|
Blinding: |
This study adopted a randomized, controlled, parallel-group design with triple blinding (participants, clinical performers, and outcome assessors were all unaware of group assignment), ensuring that intervention implementation and outcome measurement were free from expectation bias. The random allocation results were known only to independent non-clinical researchers, and all personnel involved in clinical care, data collection, follow-up, or statistical analysis remained blinded. To achieve strict blinding, all intervention drugs (including intraoperative infusions and postoperative PCIA medications) were uniformly prepared by an independent pharmacy team according to randomization numbers. All syringes, infusion bags, infusion pumps, and PCIA devices used identical-appearing, identically labeled containers, marked only with random numbers without any information on drug name, dosage, or group. The volume, appearance, color, and packaging of the drugs were consistent, so that participants in both groups could not identify their group assignment from drugs or procedures at any time of administration. |

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: |
原始数据由研究人员根据原始病历收集并记录于纸质病历报告表(CRF)或源文件中。使用风锐电子数据采集系统(Windray EDC)进行电子化数据录入、存储与管理。系统设定逻辑核查与自动校验功能,以减少数据录入错误。由临床监查员(CRA)定期进行数据核查(SDV),确保电子数据与原始记录一致。数据库由专人负责定期备份,并在统计分析前进行数据库锁定。 |
|
Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Original data will be collected by researchers from source medical records and recorded on paper Case Report Forms (CRFs) or source documents. The Free Electronic Data Capture (Free EDC) system will be utilized for electronic data entry, storage, and management. The system is configured with logic checks and automatic validation functions to minimize data entry errors. Clinical Research Associates (CRA) will perform regular Source Data Verification (SDV) to ensure consistency between the electronic data and the original records. The database will be backed up regularly by dedicated personnel and will be locked prior to statistical analysis. |
