Data Collection: All data will be sourced directly from original medical records (including anesthesia charts, nursing notes, and electronic medical records) or obtained through direct patient assessment (e.g., using standardized scales), ensuring authenticity and accuracy. A dedicated electronic Case Report Form will be created for each enrolled patient to consolidate all study-related information.Data Management: An electronic data capture system based on the REDCap platform or a comparable clinical data management system will be employed for secure data entry, storage, and management.
