研究目的:

本研究的目标旨在通过对比罗哌卡因联合地塞米松、罗哌卡因联合右美托咪定或者罗哌卡因联合地塞米松和右美托咪定,用于全膝关节置换(Total knee replacement surgery,TKA)患者股神经-闭孔神经-坐骨神经联合阻滞时的围术期镇痛效果以及不良反应发生情况,为TKA患者围术期疼痛管理探索出更为优化的药物使用方案。  

Objectives of Study:

The objective of this study is to compare the perioperative analgesic efficacy and incidence of adverse reactions among ropivacaine combined with dexamethasone, ropivacaine combined with dexmedetomidine, or ropivacaine combined with both dexamethasone and dexmedetomidine in femoral-obturator-sciatic nerve block for patients undergoing total knee replacement surgery (TKA). The aim is to explore a more optimized medication regimen for perioperative pain management in TKA patients.

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:

在数据采集方面,尽量使用电子数据采集系统(EDC)采集或录入信息,减少人为错误,提高数据录入效率;保留所有受试者的原始数据或唯一标识,确保可以溯源到原始记录。在数据整理与管理方面,尽量选择安全、科学的数据库管理系统,明确数据结构、变量定义和编码规则;使用自动验证规则和人工核查相结合的方式,定期对数据进行清洗,识别并纠正错误、缺失值、异常值或逻辑不一致的值;对可识别受试者身份信息的数据进行严格保密,有条件时采取适当的技术或管理措施,规避未经授权的访问、修改或泄露。在数据分析方面,在研究启动前,应制定详细的统计分析计划,包括主要和次要终点的定义、统计方法、样本量计算、亚组分析和敏感性分析等;随机对照试验中,尽量施行盲法以减少偏倚;数据分析结果应完整、准确、透明的报告,包括所有预设和探索分析的结果,以及可能的局限性。所有收集到的患者数据将进行匿名化处理,即用唯一的编码替代患者的真实姓名、身份证号等可识别信息。研究过程中,所有数据记录和报告均只使用这些编码,确保患者身份与数据脱钩。只有经过授权的研究团队成员才能访问研究数据,且访问权限将根据其在研究中的角色和职责进行严格限制。

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

In data collection, electronic data capture systems (EDC) should be used whenever possible to collect or enter information, minimizing human errors and improving data entry efficiency. Original data or unique identifiers for all subjects must be retained to ensure traceability to the source records. For data organization and management, secure and scientifically sound database management systems should be selected, with clear data structures, variable definitions, and coding rules. A combination of automated validation rules and manual checks should be employed to regularly clean the data, identifying and correcting errors, missing values, outliers, or logically inconsistent entries. Personally identifiable information must be strictly protected, with appropriate technical or administrative measures implemented when feasible to prevent unauthorized access, modification, or disclosure. In data analysis, a detailed statistical analysis plan should be developed before study initiation, including definitions of primary and secondary endpoints, statistical methods, sample size calculations, subgroup analyses, and sensitivity analyses. In randomized controlled trials, blinding should be implemented where possible to reduce bias. Analysis results must be reported completely, accurately, and transparently, covering all pre-specified and exploratory analyses, as well as potential limitations. All collected patient data will be anonymized by replacing identifiable information such as real names and ID numbers with unique codes. Throughout the study, only these codes will be used in data records and reports to ensure patient identities remain unlinked. Access to research data will be restricted to authorized team members, with permissions strictly limited based on their roles and responsibilities in the study.
