Sample size:

干预措施:

第一次手术:静脉开放后,患者行椎管内麻醉(腰麻复合硬膜外麻醉)+ 隐神经阻滞。切皮前10分钟,研究者按照统一流程恒速泵注由药学团队准备的艾司氯胺酮溶液,输注以 0.1mL/(kg·h)的恒定速率进行,相当于 0.20 mg/(kg·h)。输注时长1h,如果手术持续时间不足1h,研究药物将在麻醉恢复室继续进行,并在开始PCIA之前完成。艾司氯胺酮按标准稀释方法制备,即将 50 mg艾司氯胺酮加入0.9%生理盐水稀释至25 ml,总浓度2mg/ml。 术后常规给予PCIA(患者自控镇痛):舒芬太尼1.5 μg/kg + 艾司氯胺酮1 mg/kg(按实际体重计算)+昂丹司琼8mg,稀释至0.9%氯化钠注射液总量100 ml。背景剂量1 ml/h,PCA剂量2 ml/次,锁定时间15 min,持续使用48 h。 第二次手术:术中及术后均使用等容量0.9%氯化钠注射液替代艾司氯胺酮。该模拟输注保持输注泵的外观、操作与声音提示一致,从而维持盲态。PCIA配方为舒芬太尼1.5 μg/kg +昂丹司琼8mg,稀释至0.9%氯化钠注射液总量100 ml,其他参数及镇痛措施与第一次手术相同。

干预措施代码:

Intervention:

First operation: After venous access was established, the patient underwent neuraxial anesthesia (spinal anesthesia combined with epidural anesthesia) plus saphenous nerve block. Ten minutes before skin incision, the investigator infused esketamine solution prepared by the pharmacy team at a constant rate of 0.1 mL/(kg·h), equivalent to 0.20 mg/(kg·h). The infusion duration was 1 h. If the operation duration was less than 1 h, the study drug was continued in the anesthesia recovery unit and completed before initiation of PCIA. Esketamine was prepared by standard dilution: 50 mg esketamine was added to 0.9% normal saline and diluted to 25 mL, with a total concentration of 2 mg/mL. Postoperative routine PCIA (patient-controlled intravenous analgesia): sufentanil 1.5 μg/kg + esketamine 1 mg/kg (calculated by actual body weight) + ondansetron 8 mg, diluted in 0.9% sodium chloride injection to a total volume of 100 mL. Background dose 1 mL/h, PCA dose 2 mL per time, lockout time 15 min, continuous use for 48 h. Second operation: Equal volume of 0.9% normal saline was used instead of esketamine intraoperatively and postoperatively. The simulated infusion maintained the same appearance, operation and sound prompts of the infusion pump to maintain blinding. PCIA formula: sufentanil 1.5 μg/kg + ondansetron 8 mg, diluted in 0.9% sodium chloride injection to a total volume of 100 mL. Other parameters and analgesic measures were the same as those in the first operation.

盲法:

本研究采用三盲(参与者、临床实施者及结局评估者均不知情)的随机、对照、平行分组设计,以确保干预措施的实施和结果测量均不受预期偏倚影响。随机分配结果仅由独立的非临床研究人员掌握,所有参与临床照护、数据收集、随访或统计分析的人员均保持盲态。为实现严格的盲法,所有用于干预的药物(包括术中输注及术后 PCIA 药物)均由独立药学团队依据随机化编号统一制备,所有注射器、输液袋、输注泵和 PCIA 装置均使用外观一致、标签一致的容器,并仅标注随机编号而不显示任何药物名称、剂量或组别信息。药物的体积、外观、颜色及包装均保持一致,使两组参与者在任何给药时点均无法从药物或操作流程辨识所属组别。

Blinding:

This study adopted a randomized, controlled, parallel-group design with triple blinding (participants, clinical performers, and outcome assessors were all unaware of group assignment), ensuring that intervention implementation and outcome measurement were free from expectation bias. The random allocation results were known only to independent non-clinical researchers, and all personnel involved in clinical care, data collection, follow-up, or statistical analysis remained blinded. To achieve strict blinding, all intervention drugs (including intraoperative infusions and postoperative PCIA medications) were uniformly prepared by an independent pharmacy team according to randomization numbers. All syringes, infusion bags, infusion pumps, and PCIA devices used identical-appearing, identically labeled containers, marked only with random numbers without any information on drug name, dosage, or group. The volume, appearance, color, and packaging of the drugs were consistent, so that participants in both groups could not identify their group assignment from drugs or procedures at any time of administration.

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:

原始数据由研究人员根据原始病历收集并记录于纸质病历报告表(CRF)或源文件中。使用风锐电子数据采集系统(Windray EDC)进行电子化数据录入、存储与管理。系统设定逻辑核查与自动校验功能,以减少数据录入错误。由临床监查员(CRA)定期进行数据核查(SDV),确保电子数据与原始记录一致。数据库由专人负责定期备份,并在统计分析前进行数据库锁定。

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

Original data will be collected by researchers from source medical records and recorded on paper Case Report Forms (CRFs) or source documents. The Free Electronic Data Capture (Free EDC) system will be utilized for electronic data entry, storage, and management. The system is configured with logic checks and automatic validation functions to minimize data entry errors. Clinical Research Associates (CRA) will perform regular Source Data Verification (SDV) to ensure consistency between the electronic data and the original records. The database will be backed up regularly by dedicated personnel and will be locked prior to statistical analysis.
