随机方法(请说明由何人用什么方法产生随机序列): |
本研究选用区块分组,保证两组的患者数目相等或相当。区块的数目为4,A为右美托咪定0g/kg、,B为右美托咪定0.25g/kg、C为右美托咪定0.5g/kg、D为右美托咪定0.75g/kg,可能的组合为:ABCD、ADBC、ACBD、ABDC、ADCB、ACDB、BACD、BDAC、BCAD、BADC、BDCA、BCDA、CBAD、CDBA、CABD、CBDA、CDAB、CADB、DBCA、DABC、DCBA、DBAC、DACB、DCAB共24种组合。项目负责人金小高使用Excel来产生1组足够长的随机数字系列,将这组随机数字从头开始,每10个随机数(2位数)成一组,每一组随机数字对应一个日期,从2024年05月01日到2024年10 月31日。再将这每组个随机数字除以24,余数即为患者的分组,分别对应为0=ABCD、2=ADBC、3=ACBD、4=ABDC、5=ADCB、6=ACDB、7=BACD、8=BDAC、9=BCAD、10=BADC、11=BDCA、12=BCDA、13=CBAD、14=CDBA、15=CABD、16=CBDA、17=CDAB、18=CADB、19=DBCA、20=DABC、21=DCBA、22=DBAC、23=DACB、24=DCAB。 |

Randomization Procedure (please state who generates the random number sequence and by what method): |
This study uses block randomization to ensure that the number of patients in the two groups is equal or nearly equal. The number of blocks is 4, with A being dexmedetomidine 0 g/kg, B being dexmedetomidine 0.25 g/kg, C being dexmedetomidine 0.5 g/kg, and D being dexmedetomidine 0.75 g/kg. The possible combinations are: ABCD, ADBC, ACBD, ABDC, ADCB, ACDB, BACD, BDAC, BCAD, BADC, BDCA, BCDA, CBAD, CDBA, CABD, CBDA, CDAB, CADB, DBCA, DABC, DCBA, DBAC, DACB, DCAB, totaling 24 combinations. The project leader, Jin Xiaogao, uses Excel to generate a sufficiently long series of random numbers. This series of random numbers is divided starting from the beginning into groups of 10 random numbers (2-digit numbers per group), and each group of random numbers corresponds to a date from May 1, 2024, to October 31, 2024. Each group of random numbers is then divided by 24, and the remainder determines the patient's group, corresponding as follows: 0=ABCD, 2=ADBC, 3=ACBD, 4=ABDC, 5=ADCB, 6=ACDB, 7=BACD, 8=BDAC, 9=BCAD, 10=BADC, 11=BDCA, 12=BCDA, 13=CBAD, 14=CDBA, 15=CABD, 16=CBDA, 17=CDAB, 18=CADB, 19=DBCA, 20=DABC, 21=DCBA, 22=DBAC, 23=DACB, 24=DCAB. |

|
盲法: |
本试验采用双盲方法,麻醉医师负责麻醉操作,不知道预防寒颤的方法;负责记录患者麻醉效果和寒颤的麻醉护士不知道预防腰麻剖宫产患者寒颤所采用的具体麻醉方法。由一名专门的麻醉护士根据信封的规定给予预防药物。 |
|
Blinding: |
This study used a double-blind method. The anesthesiologist was responsible for anesthesia procedures and did not know the method used to prevent shivering; the anesthetic nurse responsible for recording the patient's anesthesia effects and shivering did not know the specific anesthesia method used to prevent shivering in patients undergoing spinal anesthesia for cesarean section. A dedicated anesthetic nurse administered the prophylactic medication according to the instructions in the envelope. |

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: |
数据的采集:产妇基线数据(包括一般资料、生育史、既往史等)、临床试验结果(实验室监测、影像学资料)、寒颤相关临床评估指标;所有数据将由经过培训的研究人员按照标准化操作流程(SOP)进行采集。 数据的管理:(1)数据录入:所有数据将由双人独立录入,确保准确性。(2)数据传输和存储符合《个人信息保护法》和《数据安全法》的要求。(3)数据保留期满后,将通过安全销毁程序(如碎纸机或数据擦除软件)销毁纸质和电子数据。 |
|
Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Data Collection: Baseline data of parturients (including general information, obstetric history, past medical history, etc.), clinical trial results (laboratory monitoring, imaging data), and clinical assessment indicators related to chills; all data will be collected by trained researchers following standardized operating procedures (SOP). Data Management: (1) Data Entry: All data will be entered independently by two personnel to ensure accuracy. (2) Data Transmission and Storage will comply with the requirements of the Personal Information Protection Law and the Data Security Law. (3) After the data retention period expires, both paper and electronic data will be destroyed through secure destruction procedures (such as shredders or data-wiping software). |
