研究目的: |
通过体外实验,比较麻黄碱、去氧肾上腺素、去甲肾上腺素三种升压药,以及探索去氧肾上腺素不同剂量在等效升压剂量下对接受椎管内麻醉剖宫产孕妇静脉全血 TEG 凝血特征的影响,评估其对血栓前状态的潜在影响。 |
||||||||||||||||||||||
|
Objectives of Study: |
Through in vitro experiments, we compared the effects of three vasopressors, namely ephedrine, phenylephrine, and norepinephrine, and explored the impact of different doses of phenylephrine on the TEG coagulation characteristics of whole venous blood in pregnant women undergoing cesarean section under spinal anesthesia at equivalent vasopressor doses, in order to assess its potential effects on prethrombotic states. |

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: |
本研究的数据采集和管理由病例报告表(Case Report Form, CRF)和电子数据采集与管理系统(Electronic Data Capture, EDC)两部分组成。 研究相关的临床资料(包括一般人口学信息、孕产史、麻醉与手术相关信息、实验室检查结果及 TEG 指标等)首先由经过培训的研究人员按照统一设计的纸质或电子 CRF 进行原始记录,要求及时、完整、规范填写。 随后,由两名研究人员采用双人独立录入的方式,将 CRF 数据录入本院设立的、受密码保护的电子数据采集与管理系统(EDC 数据库),定期进行一致性核对和逻辑检查,发现疑问数据及时回查原始病历或检验报告并更正。 电子数据存储于具有访问权限控制和定期备份功能的安全服务器中。所有研究数据采用唯一研究编号进行去标识化处理,将个人身份信息与研究数据库分开保存,以保障受试者隐私。仅经授权的研究者可以访问最终去标识化的数据集。 |
|
Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Clinical and laboratory data will be collected using a standardized Case Report Form (CRF) designed specifically for this study. All source data (medical records, anesthetic records, laboratory reports and TEG results) will be transcribed into the CRF by trained research staff in a timely and accurate manner. The completed CRFs will then be entered into an electronic data capture (EDC) system (a password-protected database within our institution). Double data entry and regular data validation checks will be performed to minimize entry errors and inconsistencies. All electronic data will be stored on secure, access-controlled servers with regular back-up. Personal identifiers will be removed and replaced with study codes to ensure participant confidentiality. Only authorized study personnel will have access to the final de-identified dataset. |
