研究目的:

本研究旨在通过一项前瞻性、随机对照试验,系统评估超声引导下腹股沟韧带上髂筋膜阻滞联合腘窝坐骨神经阻滞(以下称“联合神经阻滞”)应用于复杂股腘动脉腔内修复术的麻醉效果与安全性。 主要目的是评价联合神经阻滞对此类手术中最大疼痛刺激(首次球囊扩张)的镇痛效果,以术中峰值疼痛强度(数字评定量表 NRS 评分)为主要结局指标,并与常规静脉镇静镇痛方案进行对比。 次要目的包括:1)比较两组患者术中体动反应的发生情况;2)量化术中补救性镇痛药物(舒芬太尼)的用量;3)评估术中血流动力学稳定性(平均动脉压波动及血管活性药物使用情况);4)比较术后2小时及24小时的静息疼痛强度;5)记录术后24小时内阿片类药物总消耗量(换算为吗啡当量);6)比较术中转为全身麻醉的发生率;7)全面记录并评估该联合神经阻滞方案相关的不良事件(如穿刺相关并发症、呼吸抑制、恶心呕吐等)及总体安全性。  

Objectives of Study:

This prospective, randomized controlled trial aims to systematically evaluate the efficacy and safety of a combined ultrasound-guided suprainguinal fascia iliaca block and popliteal sciatic nerve block (hereafter referred to as "combined nerve blocks") for anesthesia during complex femoropopliteal artery endovascular repair. The primary objective is to assess the analgesic effect of the combined nerve blocks on the maximal intraoperative pain stimulus (first balloon dilation), with the peak intraoperative pain intensity (Numerical Rating Scale, NRS) as the primary outcome measure, compared to a conventional intravenous sedation-analgesia regimen. Secondary objectives include: 1) comparing the incidence of intraoperative body movements between groups; 2) quantifying the consumption of intraoperative rescue analgesic (sufentanil); 3) evaluating intraoperative hemodynamic stability (fluctuations in mean arterial pressure and use of vasoactive drugs); 4) comparing resting pain intensity at 2 hours and 24 hours postoperatively; 5) recording the total postoperative opioid consumption (converted to morphine equivalents) within 24 hours; 6) comparing the incidence of conversion to general anesthesia; and 7) comprehensively documenting and assessing adverse events related to the combined nerve block technique (e.g., puncture-related complications, respiratory depression, nausea and vomiting) and overall safety.

随机方法(请说明由何人用什么方法产生随机序列):

随机序列将由不参与本临床试验招募、干预与结局评估的独立统计人员,使用 SAS 9.4 统计软件(或 R 语言)生成。 具体方法为:首先按性别(男、女)进行分层,然后在每个性别层内,采用区组随机法(区组长度通常设为4或6),以1:1的比例生成分配至“联合神经阻滞组”与“常规镇静镇痛组”的随机序列。生成的序列将被密封于按顺序编号、不透光的随机信封中,交由研究协调员保管。

Randomization Procedure (please state who generates the random number sequence and by what method):

An independent statistician will generate the allocation sequence using computer software, employing stratified block randomization by sex. Assignments will be concealed in sequentially numbered, opaque, sealed envelopes. On the day of surgery, the research coordinator will open the next envelope for the corresponding stratum to reveal the group assignment. The outcome assessor and data analyst will remain blinded.

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:

病例记录表是研究数据的原始采集工具。 电子系统是数据进行录入、存储、清理与管理的核心平台。 系统建立:将CRF数据录入一个专为本研究建立的电子数据库。 核心管理流程: 双人独立录入:由两名数据录入员分别将纸质CRF数据录入电子系统,之后进行比对,任何差异都将返回原始CRF核查校正,以确保录入准确性。 逻辑核查与数据清理:在数据库中设置自动逻辑核查规则,识别异常值、逻辑错误或缺失数据。系统会生成疑问报告,由数据管理员返回研究团队核实与修正。 数据锁定:在所有数据完成清理、核查并确认无误后,由主要研究者、统计学家和数据管理员共同决定锁定数据库。锁定后,数据将不再进行任何更改,以供最终统计分析。

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

Data Collection and ManagementThe data collection and management system for this study consists of the following two components, ensuring the accuracy, completeness, and security of data from source to analysis.I. Data Collection: Case Report Form (CRF)The Case Report Form is the primary source document for data collection.Format and Content: A paper-based CRF is designed specifically for this study, containing all required variables, including demographic information, outcome measures (vital signs, pain scores, etc.), medication records, and adverse events.Collection Principles:Real-Time Recording: All data must be recorded on-site and in real-time by the designated researcher at the predefined observation time points or upon event occurrence to avoid recall bias.Division of Responsibility: Objective data (e.g., vital signs) are recorded by the anesthesia resident; subjective outcome measures (e.g., pain scores) are recorded by the blinded independent assessor.Source Data Verification: Data recorded on the CRF must be traceable back to original medical records (e.g., anesthesia chart, nursing notes) for verification.II. Data Management: Electronic Data Capture (EDC) and Management SystemThe electronic system is the core platform for data entry, storage, cleaning, and management.System Setup: Data from the CRFs are entered into a dedicated electronic database established for this study.Core Management Process:Double Data Entry: Two data entry clerks independently enter data from the paper CRFs into the electronic system. Entries are then compared, and any discrepancies are resolved by referring back to the original CRF to ensure accuracy.Logical Checks and Data Cleaning: Automated logical validation rules are programmed into the database to identify outliers, logical errors, or missing data. The system generates query reports, which are returned to the research team for verification and correction by the data manager.Database Locking: After all data have been cleaned, verified, and confirmed as accurate, the database is locked by a joint decision of the principal investigator, statistician, and data manager. No further changes are made after locking, and the data are used for final statistical analysis.Security and Confidentiality:Access Control: The electronic database implements strict access controls, allowing access only to authorized personnel at appropriate levels.Data De-identification: Subjects are identified in the database by a unique study ID only, with no directly identifiable personal information included.Secure Backup: Data are regularly backed up with encryption on password-protected servers.
