干预措施:

Interventions:

组别:

面罩联合鼻咽通气道组

样本量:

52

Group:

Face Mask with nasopharyngeal airway group

Sample size:

干预措施:

麻醉诱导前氧流量10 L/min,3min常规面罩吸氧(面罩与面部紧密贴合),患者意识消失后置入鼻咽通气道,继续面罩通气。气管插管时移除面罩,呼吸机接鼻咽通气道继续供氧。

干预措施代码:

Intervention:

Standard preoxygenation was performed with 100% oxygen at 10 L/min via a tightly sealed facemask for 3 minutes before anesthesia induction. Following loss of consciousness, a nasopharyngeal airway was inserted while continuing mask ventilation. During tracheal intubation, the facemask was removed while maintaining oxygenation by connecting the ventilator to the nasopharyngeal airway.

Intervention code:

组别:

经鼻高流量氧疗组

样本量:

52

Group:

High-flow nasal oxygen group

Sample size:

干预措施:

麻醉诱导前使用经鼻高流量吸氧,氧流量设定 50L/min,FiO2 1.0,T 37℃,3min后进行麻醉诱导,插管期间高流量吸氧装置保留。

干预措施代码:

Intervention:

Pre-induction high-flow nasal oxygen (HFNO) was administered at 50 L/min with FiO2 1.0 and 37°C for 3 minutes prior to anesthesia induction. The HFNO device was maintained throughout the intubation procedure.

随机方法(请说明由何人用什么方法产生随机序列):

随机序列由独立生物统计专家采用R语言(version 4.2.1)的blockrand程序包生成,实施中心分层(按研究中心分层)、区组长度为4的区组随机,按1:1比例将受试者分配至试验组和对照组。随机种子数(set.seed)由系统自动保存并加密,确保序列的不可预测性和可重复性。

Randomization Procedure (please state who generates the random number sequence and by what method):

The randomization sequence was generated by an independent biostatistician using R software (version 4.2.1) with the blockrand package, implementing stratified block randomization (stratified by study center with a block size of 4) to allocate participants at a 1:1 ratio to either the experimental or control group. The random seed number (set.seed) was automatically saved and encrypted by the system to ensure unpredictability and reproducibility.

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:

本研究采用标准化电子病例记录表(eCRF)进行数据采集。所有研究数据(包括基线资料、干预措施、疗效指标和不良事件)将通过eCRF直接录入,并设置逻辑校验与必填项以确保数据完整性。数据管理采用双人独立录入关键变量,并由监查员定期进行源数据核查以保证数据质量。

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

This study utilizes standardized electronic Case Report Forms (eCRFs) for data collection. All research data (including baseline characteristics, interventions, efficacy endpoints, and adverse events) will be directly entered into the eCRFs, which incorporate logical checks and mandatory fields to ensure data completeness. For data management, we implement dual independent entry for key variables, with regular source data verification by monitors to maintain data quality.
