本研究采用病例报告表和电子数据库相结合的方式进行数据采集和管理。研究者在术前访视及围术期气道管理过程中收集患者的一般资料、临床体表指标、气道超声参数及困难气道发生情况等信息。所有数据由经过培训的研究人员按照统一标准记录,并及时录入电子数据库。研究数据采用编码方式管理,去除姓名、住院号、联系电话等直接身份识别信息,仅研究团队授权人员可查阅。电子数据存储于设置密码保护的计算机或加密文件中,定期核查数据完整性和准确性,确保数据真实、完整和可追溯。

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

Data will be collected and managed using case report forms and an electronic database. General patient information, clinical physical measurements, airway ultrasound parameters, and the occurrence of difficult airway will be collected during preoperative assessment and perioperative airway management. All data will be recorded according to standardized procedures by trained research personnel and entered into the electronic database in a timely manner. The study data will be managed using coded identifiers, and direct personal identifiers such as name, hospitalization number, and telephone number will be removed. Only authorized members of the research team will have access to the data. Electronic data will be stored on password-protected computers or in encrypted files, and data completeness and accuracy will be checked regularly to ensure authenticity, integrity, and traceability.
