研究目的:

术后谵妄(postoperative delirium,POD)在老年手术患者中的发生率高达65%,会显著增加死亡率和认知功能下降风险。目前预防手段有限,亟需可推广的非药物干预措施。经皮耳迷走神经刺激(transcutaneous auricular vagus nerve stimulation,taVNS)作为一种非侵入性神经调控技术,通过调节神经炎症和自主神经功能,在降低POD风险方面展现出潜在价值。本研究采用多中心、随机、双盲、假刺激对照试验设计,旨在评估taVNS对接受全膝关节置换术(total knee arthroplasty,TKA)老年患者POD的预防效果。

Objectives of Study:

Postoperative delirium (POD) affects up to 65% of elderly surgical patients significantly increasing mortality and cognitive decline. Current prevention strategies are limited necessitating scalable non-pharmacological interventions. Transcutaneous auricular vagus nerve stimulation (taVNS) a non-invasive neuromodulation technique modulates neuroinflammation and autonomic function showing promise in reducing POD risk. This multicenter randomized double-blind sham-controlled trial evaluates the efficacy of taVNS in preventing POD among older adults undergoing total knee arthroplasty (TKA).
