Study design:

Cross-sectional 

研究目的:

(1) 主要目的 评估经皮耳迷走神经刺激(taVNS)对胃肠手术患者术后谵妄(POD)发生率的干预效果,为其作为一种非药物、可重复的谵妄预防策略提供临床依据; 分析围术期脑电监测参数的变化特点(如熵值、突发抑制指数等),探索taVNS对围术期脑功能活动的调节作用,为术中识别谵妄高风险提供潜在神经生理标志物 (2) 次要目的 观察taVNS对术后非精神症状的影响,包括睡眠质量、焦虑抑郁状态、疼痛感知及胃肠功能恢复(以首次排气时间为指标),验证其多维度围术期恢复促进效应; 评估taVNS干预的安全性与患者依从性,为该方法在围术期高龄患者中的临床推广提供可行性依据。  

Objectives of Study:

(1) Primary Objectives Evaluate the efficacy of transcutaneous auricular vagus nerve stimulation (taVNS) in reducing postoperative delirium (POD) incidence among gastrointestinal surgery patients, providing clinical evidence for its use as a non-pharmacological, repeatable delirium prevention strategy; Analyze changes in perioperative EEG monitoring parameters (e.g., entropy values, burst suppression ratio) to explore taVNS's regulatory effects on perioperative brain function, identifying potential neurophysiological markers for intraoperative high-risk delirium assessment. (2) Secondary Objectives Observe the effects of taVNS on postoperative non-psychiatric symptoms, including sleep quality, anxiety/depression status, pain perception, and gastrointestinal function recovery (measured by first flatus time), to validate its multidimensional perioperative recovery-promoting effects; Evaluate the safety and patient compliance of taVNS intervention, providing feasibility evidence for its clinical implementation in elderly perioperative patients.

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

Data will be prospectively collected by trained researchers according to a pre-specified study protocol. Baseline demographic characteristics, perioperative clinical data, intervention-related information, and outcome measures will be recorded using standardized case report forms (CRFs).Clinical assessments, including postoperative delirium evaluation, sleep quality, pain intensity, anxiety and depression symptoms, and gastrointestinal function recovery, will be conducted by assessors at predetermined time points. Assessors will be blinded to group assignment. Electroencephalogram (EEG) data will be acquired via a standardized monitoring system and stored in digital format for offline analysis. Blood samples for inflammatory and neurobiological biomarkers will be collected and processed according to institutional laboratory protocols.All study data will be entered into a secure, password-protected electronic database accessible only to authorized investigators. Data accuracy and completeness will be ensured through double-entry, periodic verification, and consistency checks. Personal identifiers will be removed and replaced with unique study identification numbers to protect participant privacy.Study documents and electronic data will be stored in accordance with institutional data protection policies and relevant regulations. Statistical analyses will use only de-identified data.
