随机方法(请说明由何人用什么方法产生随机序列): |
本研究采用分层随机化的方法。为了确保实验的可重复性,引入随机种子(Random Seed)进行本研究随机化方案设定。设定随机种子用于初始化随机数生成器的初始值。相同的随机种子将产生相同的随机数序列。因此,通过固定随机种子,可以确保每次运行程序时得到相同的随机结果。此外,为了避免性别导致耐受度差异对研究结果的影响,我们采用性别对各处理组进行分层后随机并按照该随机方案进行样本分组。 |
||||||||
|
Randomization Procedure (please state who generates the random number sequence and by what method): |
This study adopts the method of hierarchical randomization. To ensure the repeatability of the experiment, Random seeds were introduced to set the randomization protocol for this study. Set the random seed to initialize the initial value of the random number generator. The same random seeds will generate the same sequence of random numbers. Therefore, by fixing the random seed, it can be ensured that the same random result is obtained each time the program is run. Furthermore, in order to avoid the influence of gender-induced tolerance differences on the research results, we stratified each treatment group by gender and randomly assigned them, and then grouped the samples according to this randomization protocol. |

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: |
一、数据来源与产生 1. 数据来源 患者临床数据:包括人口学信息(年龄、性别)、术前检查(心电图、血常规、凝血功能)、手术记录、术后随访数据(疼痛评分、创面愈合率、炎症因子水平等)。 实验室检测数据:术前及术后血液样本检测的炎症因子(IL-6、TNF-α等)、生长因子(VEGF、EGF等)。炎症因子、生长因子检测均由团队通过试剂盒检测完成,患者不需要额外出费用。 影像学数据:超声引导下阴部神经阻滞的操作记录、创面愈合过程的图像(用于面积计算)。 2. 数据产生环节 术前:患者筛选、基线资料录入。 术中:麻醉方式、药物剂量、操作记录。 术后:疼痛评分(VAS)、补救镇痛率、创面愈合时间、不良反应监测等。 二、数据收集责任与流程 1. 数据收集责任人 临床数据:由专职数据收集员(张建栋、李垒、卓祖荫医师)负责术后随访及指标记录。 实验室数据:由中心实验室技术人员完成检测并导出标准化报告。 影像数据:由超声定位指导医师(张蓓主任)提供操作记录及图像文件。 护理数据:由护理团队(汪霞主管护师)管理药物使用记录及不良反应观察。 2. 数据录入方式 电子病例报告表(eCRF):采用REDCap或同类临床研究电子数据采集系统,设置逻辑核查功能(如范围限制、逻辑跳转),减少录入错误。 纸质记录:仅在无法实时电子录入时使用,需在24小时内转录至电子系统,并由第二人核对签名。 自动化导入:实验室检测结果通过LIS系统直接导入数据库,避免手动转录误差。 三、数据保存与保密措施 1. 数据存储 电子数据:需双因素认证(账号+密码)。 纸质数据:存放于上锁文件柜,仅授权人员可接触,研究结束后统一扫描归档并销毁原件。 2. 权限管理 数据录入员:仅限录入权限,不可修改或删除数据。 研究者:可查看本中心数据,无跨中心数据访问权限。 监查员:可审计原始数据,但需经伦理委员会审批。 数据修改流程:任何数据修改需提交书面申请,经主要研究者(PI)审批后由数据管理员执行,并记录修改时间、原因及操作人。 3.传输安全:禁止通过公共网络传输数据,需使用医院内网或加密VPN通道,文件加密采用AES-256算法。 四、质量控制与应急预案 1. 质量控制 逻辑核查:电子系统设置自动校验(如VAS评分范围0-10、日期逻辑合理性)。 双人核对:关键数据(如主要终点指标)需由两名研究人员独立录入并比对一致性。 定期监查:由独立数据监查委员会(DMC)每季度审查数据完整性及异常值。 2. 应急预案 数据丢失:每日备份至离线存储设备,异地保存。 人员变动:数据管理员需交接密钥及操作日志,签署保密协议。 五、伦理与合规性 1. 患者隐私保护 知情同意书中明确数据使用范围,患者有权随时退出研究并要求删除数据。 研究结束后,数据保存至少15年,超期后经伦理委员会批准销毁。 2. 法规遵循 符合《涉及人的生物医学研究伦理审查办法》及《个人信息保护法》要求。 多中心数据共享需签署数据使用协议,明确各方责任。 |

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
I. Data Sources and Generation 1. Data source Clinical data of patients: including demographic information (age, gender), preoperative examinations (electrocardiogram, blood routine, coagulation function), surgical records, and postoperative follow-up data (pain score, wound healing rate, inflammatory factor levels, etc.). Laboratory test data: Inflammatory factors (IL-6, TNF-α, etc.) and growth factors (VEGF, EGF, etc.) detected in blood samples before and after the operation. The detection of inflammatory factors and growth factors is all completed by the team through reagent kits, and patients do not need to pay additional fees. Imaging data: Operation records of pudendal nerve block under ultrasound guidance, images of the wound healing process (for area calculation). 2. Data generation stage Preoperative: Patient screening and baseline data entry. Intraoperative: Anesthesia method, drug dosage, operation record. Postoperative: Pain score (VAS), remedial analgesia rate, wound healing time, adverse reaction monitoring, etc. Ii. Data Collection Responsibilities and Processes Data collection responsible person Clinical data: Postoperative follow-up and index recording were handled by full-time data collectors (Physicians Zhang Jiandong, Li Lei, and Zhuo Zuyin). Laboratory data: The tests are completed by the technicians of the central laboratory and standardized reports are exported. Image data: The operation records and image files were provided by the ultrasound positioning instructor (Director Zhang Bei). Nursing data: The drug usage records and adverse reaction observations are managed by the nursing team (Head Nurse Wang Xia). 2. Data entry method Electronic Case Report Form (eCRF) : REDCap or similar clinical research electronic data acquisition systems are adopted, and logical verification functions (such as range restrictions and logical jumps) are set up to reduce input errors. Paper records: They should only be used when real-time electronic entry is not possible. They need to be transcribed to the electronic system within 24 hours and checked and signed by a second person. Automated import: Laboratory test results are directly imported into the database through the LIS system, avoiding manual transcription errors. Iii. Data Preservation and Confidentiality Measures 1. Data storage Electronic data: Two-factor authentication (account + password) is required. Paper data: Stored in locked filing cabinets, accessible only to authorized personnel. After the research is completed, they will be uniformly scanned, filed and the original documents destroyed. 2. Permission Management Data entry officer: Only entry permission is granted. Data cannot be modified or deleted. Researcher: Data from this center can be viewed, but there is no cross-center data access permission. Monitor: The original data can be audited, but it needs to be approved by the ethics committee. Data modification process: Any data modification must be submitted in writing. After approval by the principal investigator (PI), it will be carried out by the data administrator, who will record the modification time, reason, and operator. 3. Transmission Security: Data transmission through public networks is prohibited. The hospital's internal network or encrypted VPN channel must be used. File encryption adopts the AES-256 algorithm. Iv. Quality Control and Emergency Response Plan 1. Quality control Logical verification: The electronic system is set to automatically check (such as VAS score range 0-10, date logical rationality). Double-person verification: Key data (such as primary endpoint indicators) need to be independently entered and compared for consistency by two researchers. Regular monitoring: The data integrity and outliers are reviewed quarterly by an independent Data Monitoring Committee (DMC). 2. Emergency Response Plan Data loss: Back up daily to offline storage devices and save remotely. Personnel changes: Data administrators are required to hand over keys and operation logs and sign confidentiality agreements. V. Ethics and Compliance Patient privacy protection The scope of data usage is clearly defined in the informed consent form. Patients have the right to withdraw from the study at any time and request the deletion of the data. After the research is completed, the data will be retained for at least 15 years. After the expiration date, it will be destroyed with the approval of the ethics committee. 2. Compliance with regulations It complies with the requirements of the "Measures for Ethical Review of Biomedical Research Involving Human Beings" and the "Personal Information Protection Law". Multi-center data sharing requires the signing of a data usage agreement to clarify the responsibilities of all parties. |
