随机方法(请说明由何人用什么方法产生随机序列): |
本研究使用计算机生成的随机序列对患者进行随机化分组。随机序列使用区组随机化方法,区组长度从4到8随机变化,两个干预组分配比例为1:1。随机化将按照分中心进行分层随机化。本研究使用电话随机化进行分配隐藏。患者于术前访视时谈话、评估纳排标准并签署知情同意,在确定准备入手术室后,由当日负责麻醉的医师电话联系一名牵头单位、持有随机序列且不参加实际患者入组的独立联系人,获得患者干预方案,并按照干预方案对患者进行干预。 |

|
Randomization Procedure (please state who generates the random number sequence and by what method): |
In this study, patients were randomly assigned to groups using a computer-generated random sequence. The random sequence was generated using block randomization, with block lengths varying randomly from 4 to 8, and the allocation ratio between the two intervention groups was 1:1. Randomization was stratified by sub-center. Allocation concealment was implemented using telephone randomization. During the preoperative visit, patients were interviewed, assessed for inclusion and exclusion criteria, and signed informed consent. Once the patient was ready to enter the operating room, the anesthesiologist on duty contacted an independent person at the lead institution, who held the random sequence and was not involved in the actual patient enrollment, to obtain the patient's intervention plan. The patient was then treated according to the assigned intervention plan. |

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Specific Process and Key Points of Data Collection and Management in this Clinical Trial 1. Data Collection a. Objectives of Data Collection Primary Data: Perioperative blood loss: Record the amount of blood loss during surgery and within a certain period after surgery. Coagulation function indicators: Measure the patient’s coagulation function during the perioperative period, including PT (prothrombin time), APTT (activated partial thromboplastin time), INR (international normalized ratio), fibrinogen, etc. Secondary Data: Body temperature: Record the patient’s core temperature during surgery, especially the changes in temperature before, during, and after surgery at different time points. Hemodynamic parameters: Record perioperative blood pressure, heart rate, etc. Fluid intake and blood transfusion: Record the patient’s fluid intake and transfusion during and after surgery. b. Case Report Form (CRF) Design Electronic or paper-based CRF: The data items in the CRF should clearly define how all variables are to be collected to ensure that data collection during and after surgery is standardized. Data Collection Items: Patient demographic information (age, sex, medical history, etc.) Preoperative and postoperative examinations (blood test results, coagulation function indicators, etc.) Intraoperative data: blood loss, body temperature, fluid intake, transfusion, blood pressure, heart rate, etc. Postoperative follow-up data: coagulation function and related clinical indicators during recovery c. Data Collection Process Preoperative Data Collection: After patients are enrolled, a preliminary evaluation is conducted before surgery, collecting demographic data, medical history, coagulation function, temperature, and other baseline data. Intraoperative Data Collection: The core temperature during the surgery is recorded in real-time by monitoring equipment, while the surgical team regularly records blood loss, fluid intake, transfusion, and other related data. Postoperative Data Collection: After surgery, the patient's temperature, coagulation function, and other parameters continue to be monitored for a certain period. Blood loss and related clinical results are also recorded, with data primarily collected blindly by designated personnel. d. Collection Tools and Techniques Temperature Monitoring Devices: Use precise temperature monitoring devices, such as thermal control catheters or internal temperature monitoring devices, to ensure the accuracy of temperature data collection. Laboratory Testing: Blood samples are collected to test coagulation function, and laboratory instruments analyze coagulation indicators such as PT, APTT, etc. Estimation of Blood Loss: A unified and precise method combining suction devices, gauze weight, etc., is used to estimate the amount of blood loss during surgery. 2. Data Management a. Data Entry Electronic Data Capture System (EDC): All collected data is entered into the EDC system to reduce manual entry errors. Intraoperative and postoperative data can be directly input into the system through networked monitoring equipment, reducing data entry steps. Double Data Entry Mechanism: For key data (such as blood loss and laboratory test results), a double-entry mechanism is recommended, where two data management personnel enter the data separately and verify consistency. b. Data Quality Control and Verification Automated Data Quality Control Rules: Automatic quality control rules are set in the EDC system to ensure that there are no logical errors or missing values during data entry. For example, patient temperature data should be within a reasonable range, and the ratio of blood loss to fluid intake should conform to physiological norms. Handling of Outliers: When data exceeds reasonable limits, the system automatically issues a warning, prompting the researcher to verify the data or explain the abnormality. Query Management: If data issues are found (e.g., missing or inconsistent data), the data management team will send queries to the researchers, asking them to clarify or correct the data. c. Data Locking Data Freezing and Locking: Once data collection is complete and has passed quality control, the dataset is frozen, preventing further modifications. Before final analysis, all data must go through a locking procedure to ensure that the data being analyzed is the quality-controlled final version. 3. Data Security and Privacy Protection a. Data De-identification Subject Privacy Protection: All patient data should be de-identified during entry and storage, removing any information that could directly identify the patient (such as name, address, etc.), using a unique trial number instead of personal information. b. Data Access Control Only authorized personnel can access trial data. The system should use a multi-level access control mechanism to ensure that different roles (such as researchers, data managers, monitors) can only access data within their scope of responsibilities. c. Data Encryption and Backup All collected data should be transmitted through encryption and stored on the server in encrypted form. Data should also be backed up regularly to prevent data loss. 4. Preparation for Data Analysis a. Data Cleaning All data is cleaned to delete or correct unreasonable values, ensuring that the analysis dataset has no logical errors. Key data (such as blood loss, body temperature, coagulation function indicators) undergo review and consistency checks. b. Data Transformation into Analytical Format The final cleaned and quality-controlled data is exported into a format usable by statistical analysis software (such as SAS or R) and prepared for further analysis by statisticians. 5. Follow-up Data Collection and Management For a certain period after surgery, follow-up is continued to track the patient's recovery and changes in coagulation function. Follow-up data collection and management are similar to perioperative data collection, mainly including: Continuous monitoring of postoperative coagulation function Recording of postoperative body temperature and hemodynamic data Monitoring of postoperative blood loss and transfusion Conclusion In this clinical trial, data collection and management revolve around two core variables: perioperative blood loss and coagulation function. Through the carefully designed CRF, automated EDC system, and strict data quality control processes, the accuracy, completeness, and consistency of the data are ensured. At the same time, strict data security measures and compliant privacy protection procedures ensure the confidentiality of patient information and the compliance of data. |
