研究目的: |
1. 评价右美托咪定联合经耳迷走神经刺激(transcutaneous auricular vagus nerve stimulation, taVNS)在老年择期手术患者中对术后谵妄(postoperative delirium, POD)发生率的影响,明确联合干预是否较单独使用右美托咪定或常规麻醉管理进一步降低POD发生风险。 2. 评估联合干预对围术期认知功能变化的影响,采用 MoCA 量表比较术前基线、术后第5天及术后第30天的认知功能变化。 (1) 分析联合干预对围术期炎症反应水平(IL-6、TNF-α、CRP)的影响。 (2) 评价联合干预对术后恢复质量(QoR-15)及住院时间的影响。 (3) 探索炎症指标及认知功能变化之间的相关性,为围术期神经认知功能障碍风险预测研究提供依据。 |

Objectives of Study: |
1. To evaluate the effect of dexmedetomidine combined with transcutaneous auricular vagus nerve stimulation (taVNS) on the incidence of postoperative delirium (POD) in elderly patients undergoing elective surgery, and to determine whether the combined intervention further reduces the risk of POD compared with dexmedetomidine alone or conventional anesthesia management. 2. To assess perioperative changes in cognitive function using the Montreal Cognitive Assessment (MoCA) by comparing baseline scores with those obtained on postoperative day 5 and postoperative day 30. (1) To investigate the effect of the combined intervention on perioperative inflammatory responses, including interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), and C-reactive protein (CRP). (2) To evaluate postoperative recovery quality using the Quality of Recovery-15 (QoR-15) score and length of hospital stay. (3) To explore the associations between inflammatory biomarkers and cognitive function changes in the perioperative period. |

排除标准: |
1. 既往明确诊断中重度痴呆或严重认知障碍(如 MoCA 低于预设阈值,阈值按中心实际与量表版本确定); 2. 近 3 个月内卒中、癫痫频繁发作或其他严重中枢神经系统疾病导致无法完成评估; 3. 严重精神障碍(如精神分裂症、躁狂发作期)或正在使用影响评估可靠性的强镇静/抗精神病药物且无法停用; 4. 严重视力/听力障碍或语言沟通障碍导致无法完成认知测试; 5. 明确对右美托咪定过敏或禁忌;存在显著心动过缓/高度房室传导阻滞(未置入起搏器)、难治性低血压等不适合使用右美托咪定的情况; 6. taVNS 禁忌或不适用:耳廓皮肤感染/溃疡/严重湿疹、近期耳部手术或畸形影响电极放置;植入式电子装置(如心脏起搏器/除颤器)且经评估不适宜神经电刺激; 7. 预计术后需长期镇静/机械通气、无法按计划完成 PND/谵妄评估者; 8. 研究者认为不适合入组的其他情况。 |
||||||||||||||||||||||
|
Exclusion criteria: |
1. A clear diagnosis of moderate to severe dementia or severe cognitive impairment in the past (if MoCA is lower than the preset threshold, the threshold is determined according to the actual situation of the center and the version of the scale); 2. Frequent strokes, epileptic seizures or other serious central nervous system diseases within the past three months have prevented the assessment from being completed; 3. Severe mental disorders (such as schizophrenia, manic episodes) or the use of strong sedative/antipsychotic drugs that affect the reliability of assessment and cannot be discontinued; 4. Severe visual/hearing impairment or language communication disorders prevent the completion of cognitive tests; 5. Clearly identify allergies or contraindications to dexmedetomidine; There are significant bradycardia/high-grade atrioventricular block (without pacemaker implantation), refractory hypotension and other conditions that are not suitable for the use of dexmedetomidine; 6. Contraindications or inapplicability of taVNS: auricular skin infection/ulcer/severe eczema, recent ear surgery or deformity affecting electrode placement; Implantable electronic devices (such as pacemakers/defibrillators) and evaluated as unsuitable for nerve electrical stimulation; 7. Those who are expected to require long-term sedation/mechanical ventilation after surgery and are unable to complete the assessment of PND/ delirium as planned; 8. Other circumstances that the researcher deems unsuitable for enrollment. |

随机方法(请说明由何人用什么方法产生随机序列): |
本研究采用分层区组随机方法进行分组。随机序列由独立统计人员使用计算机随机数生成软件预先生成,按 1∶1∶1 比例将受试者分配至对照组、右美托咪定组及右美托咪定联合 taVNS 组。为控制不同研究中心及手术类型对主要结局的潜在影响,随机化按研究中心及手术类型进行分层。在每一分层内采用固定区组随机,区组大小设为 6 例,即每个区组内三组各分配 2 例,以保证研究过程中各组样本量的动态平衡。 |

|
Randomization Procedure (please state who generates the random number sequence and by what method): |
This study adopted the stratified block randomization method for grouping. The random sequence was pre-generated by independent statisticians using computer random number generation software. The subjects were assigned to the control group, the dexmedetomidine group, and the dexmedetomidine combined with taVNS group in a 1:1 ∶1 ratio. To control the potential impact of different research centers and surgical types on the primary outcome, randomization was stratified by research center and surgical type. Fixed block randomization was adopted within each stratification, with the block size set at 6 cases, that is, 2 cases were assigned to each of the three groups within each block, to ensure the dynamic balance of sample size in each group during the research process. |

盲法: |
本研究采用评估者盲法设计。围术期干预由指定研究人员实施,执行麻醉管理及 taVNS 操作的人员知晓分组情况,但不参与任何结局评估。所有主要和次要结局指标均由经过统一培训且未知分组信息的独立评估人员完成。数据录入及统计分析人员在数据库锁定前保持盲态。如发生严重不良事件需指导临床处理时,可按预设流程进行紧急揭盲。 |
|
Blinding: |
This study uses an assessor-blinded design. Perioperative interventions are performed by designated investigators who are aware of the group allocation but are not involved in outcome assessments. All primary and secondary outcomes are evaluated by independent assessors blinded to group allocation. Data entry personnel and statisticians remain blinded until database lock. Emergency unblinding will be allowed if required for the management of serious adverse events. |
