研究目的:

共三个目的:1.提升苏醒质量: 预期通过长效局麻药神经阻滞减少阿片类静脉麻醉药的用量,实现多模式镇痛,从而减少复苏期躁动和疼痛,改善老年患者的全麻苏醒质量。2.保护胃肠道屏障功能:阿片类药物降低胃肠道蠕动,降低胃肠道屏障功能,不利于术后恢复。本项目将“胃肠道屏障功能”(通过血浆二胺氧化酶DAO、D-乳酸等客观指标评估)作为主要观察点,旨在验证长效区域镇痛是否能通过“阿片节俭”效应,减轻对肠蠕动的抑制,保护肠道屏障,降低术后并发症。3.推动加速康复Enhanced Recovery After Surgery,ERAS实践: 本项目通过优化镇痛方案,有望缩短老年患者术后首次排气/排便时间,缩短住院日。  

Objectives of Study:

There are three purposes in total:1.It is expected that long-acting local anesthetic nerve block will reduce the dosage of intravenous opioid anesthetics and achieve multimodal analgesia, thereby reducing restlessness and pain during the recovery period and improving the quality of recovery from general anesthesia in elderly patients. 2. Protect gastrointestinal barrier function:Opioids reduce gastrointestinal motility and gastrointestinal barrier function, which is not conducive to postoperative recovery.This project takes "gastrointestinal barrier function" (assessed by objective indicators such as plasma diamine oxidase [DAO] and D-lactate) as the primary observation point. It aims to verify whether long-acting regional analgesia can reduce opioid use through its "opioid-sparing" effect, alleviate inhibition of intestinal motility, protect the intestinal barrier, and lower postoperative complications.3.Promoting the Practice of Enhanced Recovery After Surgery (ERAS): By enhancing the analgesic protocol, this project is expected to shorten the time to first postoperative flatus/defecation and reduce the length of hospital stay of elderly patients.

随机方法(请说明由何人用什么方法产生随机序列):

患者按1:1比例随机分入A组或B组。由一名独立统计学家采用计算机生成的区组随机化(区组长度为4和6)生成分配序列,并将其装入连续编号、不透光、密封的信封中。

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

Patients were randomly assigned in a 1:1 ratio to either Group A or Group B. An independent statistician generated the allocation sequence using computer-generated block randomization (block sizes of 4 and 6), which was then placed in sequentially numbered, opaque, sealed envelopes.

盲法:

由于两种研究药物(布比卡因脂质体与罗哌卡因)的物理性状存在差异,对实施神经阻滞操作的麻醉医师无法设盲。因此,本研究采用评估者盲法。所有研究用药均由不参与后续试验的临床药师根据随机序列统一配制与编号。执行阻滞的麻醉医师不参与术后的任何观察、评估与数据收集。负责术后疼痛评分、并发症记录等所有结局评估的研究人员、数据记录员以及进行最终统计分析的人员,均对患者的分组信息不知情。

Blinding:

Due to the distinct physical properties of the two study drugs (liposomal bupivacaine and ropivacaine), blinding of the anesthesiologists performing the nerve block procedure was not feasible. Therefore, an assessor-blinded design was implemented. All study medications were prepared and labeled by a clinical pharmacist, who was not involved in the subsequent trial, according to the randomization sequence. The anesthesiologist administering the block took no part in postoperative observation, assessment, or data collection. All research personnel responsible for postoperative outcome assessments (e.g., pain scores, complication records), data entry clerks, and the statistician performing the final analysis remained blinded to group allocation.
