研究目的:

提出新指标血氧积累分布面积指数(BOADAI),整合夜间睡眠期间血氧饱和度变化信息和时间信息,评估其与保留自主呼吸的全身麻醉期间呼吸不良事件(低氧血症)发生率的相关性和预测效能,为临床麻醉前评估提供新指标。  

Objectives of Study:

This study proposes a novel metric—the Blood Oxygen Accumulation Distribution Area Index (BOADAI)—which integrates nocturnal oxygen saturation dynamics with temporal information during sleep. We aimed to evaluate its correlation with and predictive performance for intraoperative respiratory adverse events, specifically hypoxemia, during general anesthesia with preserved spontaneous breathing. Our findings suggest that BOADAI may serve as an innovative preoperative indicator to enhance clinical anesthesia risk stratification.

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:

本研究的数据采集和管理将通过制定详细的标准操作程序(SOP)来实现,涵盖样本采集、数据记录、仪器操作及数据分析等全流程。研究团队将确保所有操作严格按照方案和SOP执行,并对参与人员进行统一的培训和考核,确保操作一致性。样本采集需标准化,数据记录需完整、准确且可追溯,仪器设备需定期校准并由专人负责操作。数据管理方面,将采用双人核对机制以减少录入误差,并对数据进行定期备份和加密存储以保障数据安全。研究过程中,设立质量监督小组定期检查执行情况,及时发现并纠正偏差,确保研究的科学性和结果的可靠性。最终研究报告需经过严格的内部审核,确保研究方案的完整性和结果的真实可信。

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

The data collection and management of this study will be implemented by formulating detailed Standard Operating Procedures (SOPs), covering the entire processes such as sample collection, data recording, instrument operation, and data analysis. The research team will ensure that all operations are strictly carried out in accordance with the plan and SOPs, and will provide unified training and assessment for the participating personnel to ensure operational consistency. Sample collection needs to be standardized, data records must be complete, accurate, and traceable, and instruments and equipment must be calibrated regularly and operated by designated personnel. In terms of data management, a double-check mechanism will be adopted to reduce entry errors, and data will be regularly backed up and stored in encrypted form to ensure data security. During the research process, a quality supervision team will be established to conduct regular inspections on the implementation, promptly identify and correct deviations, so as to ensure the scientificity of the research and the reliability of the results. The final research report must undergo strict internal review to ensure the completeness of the research plan and the authenticity and credibility of the results.
