研究目的:

罗哌卡因作为常用蛛网膜下腔阻滞局麻药,不同浓度可能影响阻滞特性及血流动力学稳定性。本研究旨在比较等剂量(10 mg)不同浓度罗哌卡因(0.375% vs 0.5%)对高龄患者蛛网膜下腔麻醉后低血压发生率的影响。  

Objectives of Study:

Background / Objective: Ropivacaine is a commonly used local anesthetic for spinal anesthesia. Different concentrations may affect block characteristics and hemodynamic stability. This study aimed to compare the incidence of hypotension following spinal anesthesia in elderly patients receiving an equal dose (10 mg) of ropivacaine at two different concentrations (0.375% vs. 0.5%).

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、数据采集 本研究数据采集严格按照研究方案执行,所有数据均来源于病历资料、实验室检查、影像学报告、体格检查、问卷调查、随访记录等客观、可溯源资料。由经过统一培训的研究者填写病例报告表(CRF),确保采集内容真实、完整、准确、及时。采集内容包括:受试者一般信息、基线资料、干预/治疗信息、疗效指标、安全性指标、合并用药、不良事件、退出与失访情况等。数据采集过程遵循原始资料优先原则,所有CRF数据均与原始病历一致,严禁编造、修改数据。 二、数据记录与核查 数据记录使用黑色签字笔,字迹清晰,修改时采用划改并签名、注明日期方式,不得涂改、刮擦或覆盖。 建立数据核查制度,研究团队定期对CRF与原始资料进行核对,及时发现并纠正错误、缺失或逻辑矛盾。 监查员按照监查计划进行源数据核查(SDV),确保数据真实可靠。 三、数据管理 设立数据管理员负责数据录入、整理、核对与归档。采用电子数据采集系统(EDC)方式建立研究数据库,减少录入错误。数据管理过程包括:数据接收、录入、核查、疑问澄清、数据清理、锁定。 在数据清理完成、所有疑问解决后执行数据库锁定,锁定后任何人不得擅自修改数据。

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

I. Data Collection The data collection in this study was strictly conducted in accordance with the research protocol, with all data sourced from objective and traceable materials including medical records, laboratory tests, imaging reports, physical examinations, questionnaires, and follow-up records. Case report forms (CRFs) were completed by researchers who had undergone .II. Data Recording and Verification Data records shall be made using a black ballpoint pen with clear handwriting. Modifications shall be made by crossing out the original content, signing, and noting the date. No alterations, scratches, or overwriting are permitted. A data verification system was established, with the research team conducting regular cross-checks between CRFs and raw data to promptly identify.III. Data Management Establish a data administrator responsible for data entry, organization, verification, and archiving. The research database was established using an Electronic Data Collection (EDC) system to minimize input errors. The data management process includes: data reception, entry, verification, clarification of questions, data cleansing, and locking. After data cleanup is completed and all questions are resolved, lock the database. No one may modify the data without authorization after locking.
