研究目的: |
本研究通过两部分协同设计,围绕肩部手术神经阻滞的 “镇痛有效性” 与 “膈肌 / 肺功能安全性” 双核心目标展开,具体如下: 臂丛神经上干分支点鞘膜下阻滞剂量优化目的 通过前瞻性随机双盲对照试验,验证超声引导下注射 2mL 0.375% 罗哌卡因的镇痛效果非劣于 5mL 组(以离开 PACU 前 NRS 评分差值≤1 分为非劣效界值),同时明确 2mL 剂量能否将同侧膈肌运动功能障碍(HDP)发生率降至趋近于零(≤0.1%),确定该技术的 “安全零风险剂量” 阈值;同步评估两组术后肺功能(FEV1、FVC)变化、镇痛药物用量及不良反应(如恶心呕吐、局麻药中毒),为肺功能不佳等高危肩部手术患者提供兼具镇痛可靠性与呼吸安全性的麻醉方案。 肩部手术神经阻滞技术全局比较目的 通过贝叶斯 network meta 分析,系统整合现有随机对照试验证据,全面比较肌间沟臂丛神经阻滞、锁骨上臂丛神经阻滞、肩胛上神经阻滞等 7 类技术对膈肌功能(以 HDP 发生率为核心,定义为膈肌移动度下降≥75% 或矛盾运动)及肺功能的影响;通过直接与间接比较计算风险比(RR)及 95% 可信区间,采用 SUCRA 值对 7 类技术的 HDP 风险排序,结合亚组分析(如手术类型、局麻药剂量)验证稳定性,最终形成《肩部手术神经阻滞膈肌安全选择指南》,为不同医疗机构临床医生选择膈肌安全性更优的神经阻滞技术提供标准化、高级别证据支持。 两部分研究共同推动肩部手术麻醉向 “精准定位 + 剂量控制 + 证据选优” 的方向发展,解决临床中 “镇痛 - 安全” 矛盾及技术选择难题。 |

Objectives of Study: |
This study adopts a coordinated design of two parts, focusing on the dual core objectives of "analgesic effectiveness" and "diaphragmatic/pulmonary function safety" for nerve blocks in shoulder surgery, as detailed below: Objective of Dose Optimization for Subparaneural Upper Trunk Block at the Branch Point of the Brachial Plexus Through a prospective randomized double-blind controlled trial, this part aims to verify that the analgesic effect of ultrasound-guided injection of 2mL of 0.375% ropivacaine is non-inferior to that of the 5mL group (with a non-inferiority margin of NRS score difference ≤ 1 point before leaving the Post-Anesthesia Care Unit [PACU]). Meanwhile, it intends to confirm whether the 2mL dose can reduce the incidence of ipsilateral hemidiaphragmatic dysfunction (HDP) to near zero (≤ 0.1%), thereby determining the "safe zero-risk dose" threshold of this technique. Concurrently, changes in postoperative pulmonary function (FEV1, FVC), analgesic consumption, and adverse reactions (e.g., nausea, vomiting, local anesthetic toxicity) will be evaluated between the two groups, providing an anesthetic regimen that balances reliable analgesia and respiratory safety for high-risk shoulder surgery patients with impaired pulmonary function. Objective of Global Comparison of Nerve Block Techniques for Shoulder Surgery Using Bayesian network meta-analysis, this part aims to systematically integrate evidence from existing randomized controlled trials (RCTs) to comprehensiv |

Patient data will be recorded and managed via Research Manager system (http://www.medresman.org.cn), which was a web-based platform for clinical research data management certified by the Chinese Clinical Trial Registry (http://www.chictr.org.cn). To further minimize errors, all data entries will be verified by two independent researchers. Any discrepancies will be resolved through consensus or by a third party acting as an adjudicator. The research team will be responsible for collecting and storing patient data. Upon study completion, the final dataset, along with participants’ informed consent forms, will be submitted to the Ethics Committee of Ningbo Sixth Hospital for archival storage. |
