研究目的:

本研究旨在比较高流量鼻导管氧疗(HFNC)与面罩正压通气在2岁至8岁择期全身麻醉气管插管患儿麻醉诱导期对胃充气程度及围插管期氧合安全性的影响。主要通过诱导前后右侧卧位胃窦横截面积变化量(ΔCSAa-RLD)评价胃充气程度,同时观察仰卧位胃窦横截面积变化、胃容量分级变化、预测胃容量变化以及低氧血症、反流/误吸、术后鼻部不适和术后恶心呕吐等安全性结局,为优化小儿麻醉诱导期通气/氧合策略提供临床依据。  

Objectives of Study:

This study aims to compare the effects of high-flow nasal cannula oxygenation (HFNC) and face-mask positive pressure ventilation on gastric insufflation and peri-intubation oxygenation safety during anesthesia induction in children aged 2 to <8 years undergoing elective surgery requiring endotracheal intubation. The primary objective is to evaluate gastric insufflation using the change in right lateral decubitus gastric antral cross-sectional area (ΔCSAa-RLD) before and after induction. Secondary objectives include evaluating changes in supine CSAa, gastric volume grade, predicted gastric volume, and safety outcomes including hypoxemia, regurgitation/aspiration, postoperative nasal discomfort, and postoperative nausea and vomiting.

Intervention:

During anesthesia induction, high-flow nasal cannula oxygenation (HFNC) will be used without face-mask assisted ventilation. The flow rate will be set according to body weight: 2 L/kg/min for children weighing 10–15 kg, up to 25 L/min; and 2 L/kg/min for children weighing >15–30 kg, up to 30 L/min.

诱导期采用面罩正压通气,FiO2=1.0,采用手控正压面罩通气,压力控制在安全范围内,峰压≤15 cmH2O,呼吸频率按年龄调整,I:E约1:2。如出现低氧或通气不足,立即启动救援流程。

干预措施代码:

Intervention:

Face-mask positive pressure ventilation will be applied during anesthesia induction. FiO2 will be set at 1.0. Manual positive-pressure face-mask ventilation will be performed with peak inspiratory pressure maintained within a safe range and <=15 cmH2O. Respiratory rate will be adjusted according to age, with an I:E ratio of approximately 1:2. Rescue procedures will be initiated immediately if hypoxemia or inadequate ventilation occurs.

随机方法(请说明由何人用什么方法产生随机序列):

采用1:1比例随机分配至HFNC组或面罩正压通气组。随机序列由不参与受试者入组、干预实施及结局评估的研究人员使用计算机随机数生成。

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

Participants will be randomized in a 1:1 ratio to the HFNC group or the face-mask positive pressure ventilation group. The random sequence will be generated using a computer-based random number method by a researcher who is not involved in participant enrollment, intervention implementation, or outcome assessment.

是否公开试验完成后的统计结果:

Calculated Results after the Study Completed public access:

公开/Public

盲法:

由于HFNC与面罩正压通气干预方式不同,麻醉实施者及患儿监护人无法盲法。为降低测量偏倚,本研究采用结局评估者盲法及统计分析者盲法。超声图像保存时去除分组信息,CSAa测量由不参与麻醉干预且不知晓分组的研究者完成;统计分析人员在数据库锁定前仅接触组别编码数据。

Blinding:

Blinding of anesthesiologists and guardians is not feasible due to the nature of the interventions. To reduce measurement bias, outcome assessors and statisticians will be blinded to group allocation. Ultrasound images will be stored without group information, and CSAa measurements will be performed by investigators who are not involved in anesthesia intervention and are unaware of group assignment. Before database lock, statisticians will only access coded group data.

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:

本研究采用纸质病例报告表(CRF)进行数据采集,研究数据包括受试者基本信息、纳排标准、随机分组、麻醉诱导及通气参数、胃超声测量结果、胃容量分级、预测胃容量、围术期氧合情况及不良事件等。所有数据由研究人员按受试者编号记录,去除直接身份识别信息。纸质CRF由专人保管于研究单位指定文件柜中,电子数据录入受密码保护的电脑或数据库,定期核查数据完整性和准确性。仅授权研究人员可访问研究数据。

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

Data will be collected using paper case report forms (CRFs). Study data include baseline characteristics, eligibility criteria, randomization, anesthesia induction and ventilation parameters, gastric ultrasound measurements, gastric volume grade, predicted gastric volume, perioperative oxygenation, and adverse events. All data will be recorded using participant study codes without direct personal identifiers. Paper CRFs will be stored in a designated locked cabinet at the study site, and electronic data will be entered into password-protected computers or databases. Data completeness and accuracy will be checked regularly. Only authorized study personnel will have access to the study data.
