纳入标准:

Inclusion criteria

排除标准:

1.有结直肠手术史(如结肠切除术、回肠储袋手术等)者; 2.存在严重影响胃肠道功能的疾病(如炎症性肠病活动期、顽固性便秘、肠梗阻等); 3.患有严重的、未控制的心脑血管、肝脏、肾脏或呼吸系统疾病; 4.耳廓局部有感染、破损或畸形,不适合进行taVNS设备佩戴者; 5.体内植入心脏起搏器、除颤器或其他电子植入式医疗设备(避免taVNS的电刺激干扰); 6.有迷走神经兴奋性增高相关疾病或对迷走神经刺激有禁忌症者(如严重心动过缓、颈动脉窦过敏综合征等); 7.既往有癫痫、抑郁症等神经系统或精神疾病史,并正在接受相关治疗(以避免VNS原有适应症的干扰); 8.长期服用可能显著影响胃肠动力的药物(如阿片类止痛药、抗胆碱能药物等),且在检查前无法按要求停药; 9.已知对研究中所用清肠剂成分过敏者; 10.妊娠期、哺乳期女性。

Exclusion criteria:

1.History of colorectal surgery (e.g., colectomy, ileal pouch surgery, etc.); 2.Presence of diseases severely affecting gastrointestinal function (e.g., active inflammatory bowel disease, refractory constipation, intestinal obstruction, etc.); 3.Severe, uncontrolled cardiovascular and cerebrovascular, hepatic, renal, or respiratory diseases; 4.Local infection, damage, or deformity of the auricle, making it unfit for wearing transcutaneous auricular vagus nerve stimulation (taVNS) devices; 5.Implanted cardiac pacemakers, defibrillators, or other electronic implantable medical devices in the body (to avoid electrical stimulation interference from taVNS); 6.Diseases associated with increased vagal excitability or contraindications to vagus nerve stimulation (e.g., severe bradycardia, carotid sinus hypersensitivity syndrome, etc.); 7.Past history of neurological or psychiatric diseases such as epilepsy or depression, and currently receiving relevant treatment (to avoid interference from the original indications of VNS); 8.Long-term use of drugs that may significantly affect gastrointestinal motility (e.g., opioid analgesics, anticholinergic drugs, etc.), and inability to discontinue the drugs as required before the examination; 9.Known allergy to the components of the laxatives used in the study; 10.Pregnant or lactating women.

Group:

3L PEG Group

Sample size:

干预措施:

根据《结肠镜检查肠道准备专家共识意见(2023,广州)》中的常规3L PEG方案:检查前一晚20:00口服1L 聚乙二醇电解质散;检查前4-6h口服2L聚乙二醇电解质散,且要求在1h内服完,服药由研究者床旁指导完成。

干预措施代码:

Intervention:

According to the conventional 3L PEG regimen in the Expert Consensus on Bowel Preparation for Colonoscopy (2023, Guangzhou): 1L of polyethylene glycol (PEG) electrolyte powder shall be taken orally at 20:00 on the night before the colonoscopy; 2L of PEG electrolyte powder shall be taken orally 4-6 hours before the colonoscopy, and shall be completed within 1 hour. All medication administrations shall be performed under the bedside guidance of researchers.

Intervention code:

组别:

taVNS+2.5L PEG组

样本量:

35

Group:

taVNS+2.5L PEG Group

Sample size:

干预措施:

检查前一晚20:00口服1L PEG时使用taVNS干预30min,检查前4-6h口服1.5 L PEG,服用开始时同步使用taVNS干预30min,服用结束4h时再使用taVNS干预30min,三次干预均由研究者在床旁指导完成。

干预措施代码:

Intervention:

At 20:00 on the night before the colonoscopy, participants will receive transcutaneous auricular vagus nerve stimulation (taVNS) for 30 minutes concurrently with oral administration of 1L polyethylene glycol (PEG) electrolyte powder; 4-6 hours before the colonoscopy, participants will take 1.5L PEG electrolyte powder orally, and taVNS intervention will be initiated concurrently with the start of PEG administration for 30 minutes; an additional 30-minute taVNS intervention will be performed 4 hours after the completion of PEG administration. All three interventions will be conducted under the bedside guidance of researchers.
