研究目的:

主要目的:构建并验证脑电(EEG)–心电(ECG)–有创动脉血压(IABP)多模态耦合的时变分析方法,并基于时变 Granger 因果分析定量描述老年患者在清醒期、诱导期、维持期与苏醒期的脑-心耦合强度与方向性变化; 次要目的:探索耦合指标与麻醉深度指数(AI)、重心频率以及抑制持续时间的关联; 探索性目的:初步分析脑-心耦合指标与术后早期认知变化的相关性,为未来大样本预测模型提供初步依据。  

Objectives of Study:

Main objective: To construct and validate a time-varying analysis method for the multimodal coupling of electroencephalogram (EEG), electrocardiogram (ECG), and invasive arterial blood pressure (IABP), and to quantitatively describe the changes in the strength and direction of brain-heart coupling in elderly patients during the awake period, induction period, maintenance period, and recovery period using time-varying Granger causality analysis; Secondary objective: To explore the correlations between coupling indicators and anesthesia depth index (AI), center frequency, and inhibition duration; Exploratory objective: To preliminarily analyze the correlation between brain-heart coupling indicators and early postoperative cognitive changes, providing preliminary basis for future large-sample prediction models.

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:

病例记录表(CRF, Case Report Form):通过术前访谈、病历查阅、术中监测及术后访谈等方式收集数据,包括人口学信息、病史、术中监测数据(脑电图、心电图、有创动脉血压等)、术前及术后认知功能评估结果等。所有信息将记录在标准化的纸质和电子病例记录表中,并采用预设编码管理,确保患者信息安全。 电子数据采集和管理系统(EDC, Electronic Data Capture System):收集的病例记录表数据将同步录入加密的电子数据库,由授权研究人员访问。系统设有访问控制、活动日志和定期备份机制,以确保数据完整性、可追溯性和安全性。所有数据在录入后进行去标识化处理,删除姓名、身份证号、联系方式及住院号等可识别个人信息。数据仅用于本研究及经批准的学术研究目的,禁止商业使用或试图重新识别受试者。

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

Case Report Form (CRF): Data is collected through preoperative interviews, review of medical records, intraoperative monitoring, and postoperative interviews, including demographic information, medical history, intraoperative monitoring data (electroencephalogram, electrocardiogram, invasive arterial blood pressure, etc.), preoperative and postoperative cognitive function assessment results, etc. All information will be recorded on standardized paper and electronic case report forms and managed using preset coding to ensure patient information security. Electronic Data Capture System (EDC): The collected case report form data will be simultaneously entered into an encrypted electronic database and accessed by authorized researchers. The system has access control, activity logs, and regular backup mechanisms to ensure data integrity, traceability, and security. All data undergo de-identification processing after entry, with names, ID numbers, contact information, and hospital numbers, etc., being deleted to remove identifiable personal information. The data is only used for this research and approved academic research purposes and is prohibited from commercial use or attempts to re-identify the subjects.
