研究目的: |
主要目标:评估右美托咪定对胃肠肿瘤手术患者术后神经认知恢复延迟(dNCR)的影响。 次要目标:观察右美托咪定对术中脑血流自动调节(CA)功能的影响,分析术后神经认知恢复延迟(dNCR)与术中脑血流自动调节(CA)功能的相关性。 |

|
Objectives of Study: |
Primary objectives: To evaluate the effect of dexmedetomidine on postoperative delayed neurocognitive recovery (dNCR) in patients undergoing gastrointestinal tumor surgery. Secondary objectives: To observe the effect of dexmedetomidine on intraoperative cerebral blood flow autoregulation (CA) function, and analyze the correlation between postoperative delayed neurocognitive recovery (dNCR) and intraoperative cerebral blood flow autoregulation (CA) function. |

Exclusion criteria: |
1. preoperative presence of severe cerebrovascular disease that may affect the functional assessment of cerebral blood flow autoregulation (e.g., severe intracranial arterial stenosis, acute phase of cerebral infarction <3 months, sequelae of severe craniocerebral injury, etc.); 2. Presence of a clear preoperative history of central nervous system disease (e.g., depression, schizophrenia, epilepsy, Parkinson's disease, Alzheimer's disease, etc.); 3. the presence of severe communication deficits that prevent completion of the Neurocognitive Functioning Scale assessment (e.g., coma, severe hearing or visual impairment, aphasia, inability to understand the study language, etc.); 4. the presence of cognitive dysfunction (illiteracy <= 17 points, primary school education <= 20 points, secondary school education and above <= 24 points) as assessed by the Modified Mental State Examination (MMSE) preoperatively; 5. Presence of severe bradycardia or conduction block (pathological sinus node syndrome, heart rate <50 beats/min, atrioventricular block of degree II and above without pacemaker protection); 6. Combined severe cardiac insufficiency (NYHA cardiac class III or IV) or severe hepatic insufficiency (Child-Pugh class C); 7. Severe renal insufficiency requiring preoperative renal replacement therapy; 8. Uncontrolled hypertension (systolic blood pressure > 180 mmHg or diastolic blood pressure > 110 mmHg); 9. patients on long-term use of α2-adrenergic agonists (e.g. colistin) or antagonists; 10. known hypersensitivity to dexmedetomidine or its preparatory excipients. |

随机方法(请说明由何人用什么方法产生随机序列): |
采用区组随机化方法进行分组。由不参与患者招募、麻醉管理与结果评估的独立研究人员,使用统计软件生成随机序列。采用动态区组长度(例如,在4和6之间随机选择),按1:1的比例将合格受试者分配至右美托咪定组(D组)与生理盐水对照组(C组)。 |
||||||||
|
Randomization Procedure (please state who generates the random number sequence and by what method): |
Block randomization was used for grouping. Independent researchers who were not involved in patient recruitment, anesthesia management and outcome evaluation generated random sequences using statistical software. The eligible subjects were assigned to dexmedetomidine group (Group D) and normal saline control group (Group C) in a 1:1 ratio using the dynamic zone length (for example, randomly selected between 4 and 6). |
