研究目的:

探讨经皮耳迷走神经电刺激对下肢手术止血带应用诱发老年患者术后谵妄的预防效果,并从炎症反应、缺氧应激及中枢胆碱能系统调控角度阐明其潜在作用机制  

Objectives of Study:

To investigate the preventive effect of transcutaneous auricular vagus nerve stimulation (taVNS) on postoperative delirium (POD) induced by tourniquet application in elderly patients undergoing lower extremity surgery, and to clarify its potential mechanism from the perspectives of inflammatory response, hypoxic stress and central cholinergic system regulation.

Description for medicine or protocol of treatment in detail:

 

纳入标准:

1、年龄>=65 岁,性别不限; 2、期行下肢骨科手术,术中计划使用止血带; 3、美国麻醉医师协会(American Society of Anesthesiologists,ASA)分级 Ⅰ~Ⅲ 级; 4、术前认知功能基本正常,MoCA 评分>=26 分、MMSE 评分>=24 分; 5、患者或其法定代理人充分知情并签署书面知情同意书。

Inclusion criteria

1. Age >= 65 years, any gender; 2. Scheduled for lower limb orthopedic surgery, with planned use of a tourniquet during surgery; 3. American Society of Anesthesiologists (ASA) classification I–III; 4. Basic normal cognitive function before surgery, MoCA score >= 26, MMSE score >= 24; 5. Patient or their legal representative is fully informed and has signed written informed consent.

排除标准:

1、术前存在谵妄、痴呆(MoCA<26 分或 MMSE<24 分)或严重神经精神疾病(精神分裂症、双相情感障碍、癫痫等); 2、合并耳部疾病(中耳炎、耳廓畸形、耳部皮肤破损 / 感染)或中重度听力障碍; 3、体内植入心脏起搏器、除颤器等电子植入式设备; 4、凝血功能障碍(INR>1.5 或 PLT<50×10?/L)或正在使用长期抗凝药物; 5、对电刺激不耐受、无法配合量表评估或随访; 6、严重肝肾功能不全(Child-Pugh B 级及以上、血肌酐 > 177μmol/L)、恶性肿瘤或全身活动性感染。

Exclusion criteria:

1. Preoperative presence of delirium, dementia (MoCA <26 points or MMSE <24 points) or severe neuropsychiatric disorders (schizophrenia, bipolar disorder, epilepsy, etc.); 2. Concurrent ear diseases (otitis media, auricle deformity, ear skin damage/infection) or moderate to severe hearing impairment; 3. Implanted electronic devices in the body such as cardiac pacemakers or defibrillators; 4. Coagulation disorders (INR >1.5 or PLT <50×10?/L) or ongoing long-term anticoagulant therapy; 5. Intolerance to electrical stimulation, inability to cooperate with scale assessments or follow-ups; 6.

干预措施:

Interventions:

组别:

迷走神经刺激组

样本量:

78

Group:

taVNS intervention group

Sample size:

干预措施:

观察组采用经皮耳迷走神经电刺激仪,将一次性刺激电极贴于患者左耳廓迷走神经耳支分布区(耳甲腔后 1/3 处);刺激参数:连续波,频率 20 Hz,脉宽 200 μs,初始电流强度 2 mA,以 “患者感到轻微刺麻感且无明显不适” 为标准,逐渐调整至 5~8 mA 并维持。干预时间:1、术前 1 d:于病房行单次干预,时长 30 min;2、手术当日:麻醉诱导前 30 min 启动干预,持续至手术结束后止血带放气 30 min,术中刺激强度维持术前耐受强度的 80%(避免麻醉状态下患者对刺激不敏感导致强度过高);3、术后 1 d:于病房行单次干预,时长 30 min,电流强度同术前1d。

干预措施代码:

Intervention:

The observation group used the vagus nerve stimulator and the disposable stimulation electrode was attached to the distribution area of the auricular branch of the vagus nerve in the left auricle (the posterior 1/3 of the concha cavity); the stimulation parameters were: continuous wave, frequency 20 Hz, pulse width 200 μs, initial current intensity 2 mA, adjusted gradually to 5~8 mA and maintained with the standard of "the patient feels slight tingling and numbness without obvious discomfort". Intervention time: 1. The first day before surgery: a single intervention was performed in the ward for 30 min; 2.The operation day: the intervention was started 30 minutes before anesthesia induction and continued until 30 minutes after tourniquet deflation after the end of surgery, and the intraoperative stimulation intensity was maintained at 80% of the preoperative tolerance intensity (to avoid excessive intensity due to the patient's insensitivity to stimulation under anesthesia); 3.The first day after surgery: a single intervention was performed in the ward for 30 min with the same current intensity as the first day before surgery.

组别:

对照组

样本量:

78

Group:

Control group

Sample size:

干预措施:

对照组佩戴与观察组完全相同的刺激电极及设备,电极放置位置、干预时长与观察组一致;在患者报告感到轻微刺麻感后,立即关闭设备电流输出,全程无有效电刺激,仅保持设备开机状态以保证盲法有效性。

干预措施代码:

Intervention:

The control group wore the same stimulation electrodes and equipment as the observation group, with the same electrode placement position and intervention duration as the observation group; after the patient reported feeling slight tingling and numbness, the device current output was turned off immediately, without effective electrical stimulation throughout the process, and only the device was kept on to ensure the effectiveness of blinding.
