研究目的:

膝关节置换术作为治疗终末期膝关节病变的有效手段,其术后中重度疼痛是影响患者预后的关键因素之一。为了减少阿片类药物的使用,临床推荐多模式镇痛策略,其中局部麻醉药物发挥着重要作用。布比卡因脂质体作为一种具有缓释机制的新型长效局麻药,能够有效延长镇痛时间,减少术后并发症,提高生活质量,加速康复进程,成为术后疼痛管理的重要工具。本研究为布比卡因脂质体应用于神经阻滞在全膝关节置换术后镇痛中提供了新的临床证据,具有重要的应用价值和广阔的发展前景。  

Objectives of Study:

As an effective treatment for end-stage knee joint disease, total knee arthroplasty (TKA) presents significant challenges with moderate-to-severe postoperative pain that critically impacts patient outcomes. To reduce opioid dependency, clinicians recommend multimodal analgesia strategies, where local anesthetics play a pivotal role. Bupivacaine liposome—a novel long-acting local anesthetic with sustained-release properties—provides extended pain relief, reduces postoperative complications, improves quality of life, and accelerates recovery, establishing it as a crucial tool in pain management. This study provides new clinical evidence supporting the application of bupivacaine liposome in nerve block-based analgesia for post-TKA pain management, demonstrating substantial clinical value and promising development potential.
