研究目的: |
通过单中心随机对照试验,评估经皮耳迷走神经刺激(taVNS)对老年下肢骨科手术患者术后谵妄(POD)发生率的影响,明确taVNS是否能够有效降低POD的发生风险。通过检测患者粪便及血清样本,分析taVNS对肠道菌群及中性粒细胞外诱捕网(NETs)标志物水平的影响,探讨taVNS改善POD的潜在机制是否与调控肠道菌群及NETs形成有关。 |

|
Objectives of Study: |
This study aims to evaluate the effect of transcutaneous auricular vagus nerve stimulation (taVNS) on the incidence of postoperative delirium (POD) in elderly patients undergoing lower extremity orthopedic surgery through a single-center randomized controlled trial. The primary objective is to determine whether taVNS can effectively reduce the risk of POD. Secondary objectives include analyzing the effects of taVNS on gut microbiota composition and levels of neutrophil extracellular traps (NETs) markers by detecting patient fecal and serum samples, and investigating whether the potential mechanism of taVNS in improving postoperative delirium is associated with the regulation of gut microbiota and NETs formation. |
