随机方法(请说明由何人用什么方法产生随机序列):

负责人:由不参与临床操作、不接触受试者、不参与结果评估与数据分析的独立统计师(例如医院临床研究中心或第三方统计学专家)负责生成随机序列。 方法:采用计算机随机数生成器(如SAS、R或Stata软件),以 1:1:1 的比例生成区组随机化序列(区组大小为6或随机可变),共生成与计划样本量(120例)对应的随机分配编码。 流程:独立统计师将生成的随机序列直接密封交给试验药品调配药师,不告知任何临床研究人员。

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

Random Sequence Generation Responsible party: An independent statistician (e.g., from the hospital’s clinical research center or a third-party statistical expert) who is not involved in clinical procedures, participant contact, outcome assessment, or data analysis will generate the randomization sequence. Method: A computer random number generator (using software such as SAS, R, or Stata) will be used to generate a block randomization sequence (block size of 6 or randomly varying) in a 1:1:1 ratio, producing randomization codes corresponding to the planned sample size (120 participants). Procedure: The independent statistician will seal the generated randomization sequence and deliver it directly to the pharmacist responsible for test drug preparation, without disclosing it to any clinical research staff.

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:

受试者盲:患者不知分组情况。 评估者盲:所有术后疼痛评估、功能评估、随访人员均不知分组。 分析者盲:数据分析阶段,统计师仅收到以“A组、B组、C组”编码的数据集,最终分析完成后由独立统计师揭盲并交由研究负责人解读。 操作者不盲但受限:麻醉医生与外科医生因注射操作需要知晓药物编号,但不知具体成分(药物外观一致、仅标有编号)。他们承诺不向任何人透露编号对应的分组信息。

Blinding:

Participant blinding: Participants will not know their group assignment. Outcome assessor blinding: All personnel performing postoperative pain assessments, functional evaluations, and follow-up will be blinded to group allocation. Data analyst blinding: During the data analysis phase, the statistician will receive a dataset coded only as "Group A, Group B, Group C." Unblinding will be performed by the independent statistician after final analysis, and the results will be disclosed to the principal investigator for interpretation. Operator non-blinded but restricted: Anesthesiologists and surgeons need to know the drug kit number for injection procedures, but they will not know the specific composition (all drugs have identical appearance and are labeled only with the number). They are required to commit to not revealing any group-related information corresponding to the number to any other person.

After the research is completed and the paper is published, the raw data will be uploaded to a data repository linked to the paper for retrieval.

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:

数据采集由盲态评估者使用相对应的临床量表评估完成,人工采集,所有数据最终导入EXCEL表进行管理和分析。

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

Data collection was performed manually by blinded assessors using corresponding clinical scales, and all data were ultimately imported into Excel for management and analysis.
