研究目的: |
旨在前瞻性采集围麻醉期的多模态数据(包括监护屏视频、麻醉机与麻醉深度监测画面、设备报警音及有创动脉压信号),结合大模型方法,建立并验证术中血压管理的决策支持模型,用于术中血压异常事件及其干预过程的识别与分析。 |

|
Objectives of Study: |
This study aims to prospectively collect multimodal peri-anesthesia data—including monitor screen videos, anesthesia machine and depth-of-anesthesia displays, equipment alarms, and invasive arterial pressure (IAP) signals. By leveraging large-scale model techniques, we aim to develop and validate a clinical decision support system (CDSS) for intraoperative blood pressure management. This model will be utilized to identify and analyze abnormal intraoperative blood pressure events and their corresponding intervention processes. |

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: |
1. 病例报告表 (CRF) 本研究根据方案设计标准化CRF,涵盖以下核心内容:基线资料: 患者基本信息(年龄、BMI、ASA分级)、合并疾病(高血压、糖尿病、心肾功能不全等)及术前用药情况(ACEI/ARB等)。手术与监测: 手术类型、体位、气腹压、禁食补液状态及术前7天内实验室指标。事件标注: 详细记录术中高/低血压事件的起止时间、极值、临床操作锚点(给药、插管、切皮等)及相应干预措施。 2. 电子数据采集与管理系统 (EDC)。本研究采用自主研发多模态数据库平台进行全流程数据管理:数据录入与同步: 去标识化后的临床资料通过平台录入,系统内置逻辑校验以减少人工误差。平台通过本地时间服务器实现音视频监控、麻醉机参数与逐搏有创血压信号的毫秒级对齐。权限与质量控制: 实施严格的权限分级(采集、标注、分析、审计),确保职责清晰。系统集成双人独立标注与一致性评价模块(Cohen’s κ/Gwet’s AC1),并自动留存操作日志(Audit Trail)以保证过程可追溯。数据安全: 采用AES256加密存储与VPN安全接入,数据定期自动备份。所有导出操作均需经科室与伦理委员会双重审批,研究结束后原始数据至少保存五年。 |

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Data Collection and Management1. Case Report Form (CRF)A standardized CRF has been designed according to the study protocol, covering the following core components:Baseline Data: General patient information (age, BMI, ASA physical status), comorbidities (hypertension, diabetes, cardiac or renal insufficiency, etc.), and preoperative medication history (e.g., ACEI/ARB).Surgical and Monitoring Data: Type of surgery, surgical positioning, pneumoperitoneum pressure, fasting/fluid status, and laboratory indicators within 7 days prior to surgery.Event Annotation: Detailed records of the onset and offset times of intraoperative hypertensive/hypotensive events, peak/trough values, clinical procedural anchors (e.g., drug administration, intubation, skin incision), and corresponding interventions.2. Electronic Data Capture and Management System (EDC)This study utilizes a Self-Developed Multimodal Database Platform for comprehensive data management:Data Entry and Synchronization: De-identified clinical data are entered through the platform, which features built-in logic checks to minimize human error. The platform achieves millisecond-level alignment of audiovisual monitoring, anesthesia machine parameters, and beat-to-beat invasive blood pressure signals via a local time server.Permissions and Quality Control: A strict hierarchical access control system (Collector, Annotator, Analyst, and Auditor) is implemented to ensure clear accountability. The system integrates a dual-independent annotation and consistency evaluation module (using Cohen’s $\kappa$ and Gwet’s AC1) and automatically maintains an Audit Trail to ensure full traceability.Data Security: Data are stored with AES256 encryption and accessed via a secure VPN. Regular automated backups are performed. Any data export requires dual approval from both the department and the Ethics Committee. Raw data will be retained for at least five years following the conclusion of the study. |
