研究目的: |
(1)主要目的:通过功能性磁共振成像 (fMRI) 技术, 比较右美托咪定、瑞马唑仑和生物反馈放松系统三种干预方式对老年创伤患者术后记忆编码相关脑区 (海马体) 和疼痛处理相关脑区 (岛叶、前扣带回) 功能活动的影响。 (2)次要目的:评估三种干预方式对患者围术期神经内分泌应激反应(包括皮质醇、肾上腺素、去甲肾上腺素、胰高血糖素) 和免疫指标 (免疫球蛋白、α-唾液淀粉酶) 的动态变化规律。分析三种干预方式对患者术后疼痛感知 (VAS 评分) 、焦虑状态 (HAMA 评分) 、抑郁症状 (SDS评分) 、睡眠质量 (AIS 评分) 和认知功能 (MoCA 评分) 的改善效果。探讨脑功能活动变化与神经内分泌指标、临床行为学表现之间的相关性。评估不同干预方式对患者术后谵妄发生率、并发症、及住院时间等临床结局的影响。 (3)探索性目的:建立脑功能活动指标与神经内分泌应激反应的多元预测模型,识别围术期神经功能保护的关键预测因子。本研究将通过多维度、多时间点的系统评估,为老年患者围术期神经功能保护提供新的理论基础和临床实践依据。研究结果有望为个体化麻醉方案的选择和围术期脑保护策略的制定提供高级别循证医学证据。 |

Objectives of Study: |
1. Primary Objective: To compare the effects of three interventions—dexmedetomidine, remimazolam, and a biofeedback relaxation system—on functional activity in brain regions associated with postoperative memory encoding (hippocampus) and pain processing (insula and anterior cingulate cortex) in elderly trauma patients, using functional magnetic resonance imaging (fMRI). 2.Secondary Objectives: To evaluate the dynamic changes in perioperative neuroendocrine stress responses (including cortisol, epinephrine, norepinephrine, and glucagon) and immune parameters (immunoglobulins and alpha-amylase) under the three interventions. To assess the improvements in postoperative pain perception (Visual Analog Scale, VAS), anxiety status (Hamilton Anxiety Rating Scale, HAMA), depressive symptoms (Self-Rating Depression Scale, SDS), sleep quality (Athens Insomnia Scale, AIS), and cognitive function (Montreal Cognitive Assessment, MoCA) following the three interventions. To explore the correlations between changes in brain functional activity and neuroendocrine indicators as well as clinical behavioral manifestations. To evaluate the effects of the different interventions on clinical outcomes including the incidence of postoperative delirium, complications, and length of hospital stay. 3. Exploratory Objective: To develop a multivariate predictive model integrating brain functional activity indicators and neuroendocrine stress responses, and to identify key predictive factors for perioperative neurofunctional protection. Through a multidimensional, multi-time-point systematic assessment, this study aims to provide a new theoretical basis and clinical practice evidence for the protection of perioperative neurological function in elderly patients. The findings are expected to provide high-level evidence-based medical support for the selection of individualized anesthesia regimens and the development of perioperative brain protection strategies. |

随机方法(请说明由何人用什么方法产生随机序列): |
使用SAS 9.4或R软件中的sample()函数生成随机序列。区组长度设为4或8,随机混合。以1:1:1:1的比例将受试者分配至四个组别。 |

Randomization Procedure (please state who generates the random number sequence and by what method): |
A random allocation sequence will be generated using SAS 9.4 or R software (e.g., the sample() function). A mixed block design with block sizes of 4 or 8 will be used. Participants will be assigned to the four groups in a 1:1:1:1 ratio. |

盲法: |
本试验为单盲设计。施盲对象为受试者(受试者对分组情况不知情)。此外,结局评估者(如fMRI数据分析师、疼痛及认知功能评估人员)不参与分组过程且不知晓分组情况。由于麻醉方案及设备(TCI泵)的差异,麻醉实施者和研究者无法对干预措施实施盲法。 |
|
Blinding: |
This is a single-blind trial. The blinding applies to the participants (participants are unaware of group assignment). Additionally, outcome assessors (e.g., fMRI data analysts, personnel evaluating pain and cognitive function) are not involved in group allocation and remain blinded to group assignment. Due to differences in anesthesia protocols and equipment (TCI pump), the anesthesia providers and investigators cannot be blinded to the interventions. |

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC: |
本研究数据采集和管理采用标准病例记录表(CRF)与电子数据采集系统(EDC,如ResMan)相结合的方式。CRF记录的主要指标包括脑区激活变化(fMRI Z值)、疼痛强度(视觉模拟评分法VAS或数字评定量表NRS-11)、焦虑状态(汉密尔顿焦虑量表HAMA)、抑郁状态(抑郁自评量表SDS)、睡眠质量(阿森斯失眠量表AIS)、认知功能(蒙特利尔认知评估量表MoCA),以及血液指标:激素类(血清皮质醇、肾上腺素、去甲肾上腺素、胰高血糖素)、交感神经活性标志物(α-唾液淀粉酶)、免疫球蛋白与炎症因子(血清免疫球蛋白A、免疫球蛋白G、白细胞介素-6)。以上指标按照研究方案设定的时间点采集并记录于CRF,经双人核对后录入EDC系统,系统设置逻辑核查与修改痕迹追踪,确保数据真实、完整、可溯源。 |

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Data collection and management in this study will be conducted using a standardized Case Record Form (CRF) in combination with an electronic data capture system (EDC, e.g., ResMan). The CRF will record the primary outcome measures including changes in brain region activation (fMRI Z-scores), pain intensity (Visual Analog Scale, VAS, or Numerical Rating Scale, NRS-11), anxiety status (Hamilton Anxiety Rating Scale, HAMA), depressive symptoms (Self-Rating Depression Scale, SDS), sleep quality (Athens Insomnia Scale, AIS), cognitive function (Montreal Cognitive Assessment, MoCA), as well as blood biomarkers: hormones (serum cortisol, epinephrine, norepinephrine, glucagon), a sympathetic activity marker (α-salivary amylase), and immunoglobulins/inflammatory factors (serum immunoglobulin A, immunoglobulin G, and interleukin-6). These indicators will be collected at time points specified in the study protocol and recorded on the CRF. After double-checking, the data will be entered into the EDC system, which employs logic checks and an audit trail to ensure data authenticity, completeness, and traceability. |
