研究目的:

本研究旨在通过一项前瞻性随机对照试验,系统评估高流量鼻吸氧在急诊患儿快速顺序诱导中的应用价值。我们将精确量化HFNC对非缺氧性呼吸暂停时间的延长效果,并通过体重分层分析明确其在不同生理发展阶段患儿的干预效能;同时全面评估其临床应用安全性,重点监测鼻腔损伤及低氧血症等不良反应发生率;进一步借助肺超声等多模态监测技术,深入揭示HFNC通过改善肺泡通气状态维持氧合稳定的生理机制。最终,本研究致力于为急诊饱胃患儿提供一种"无加压、低风险"的优化氧疗方案,为降低儿童围术期麻醉相关并发症提供高级别循证依据。  

Objectives of Study:

This prospective randomized controlled trial aims to systematically evaluate the application value of high-flow nasal cannula (HFNC) oxygen therapy during rapid sequence induction (RSI) in pediatric emergency patients. We will accurately quantify the efficacy of HFNC in prolonging non-hypoxemic apneic time and clarify its intervention effects in children at different developmental stages via stratified analysis by body weight. Meanwhile, the clinical safety of HFNC will be comprehensively assessed, with a focus on the incidence of adverse events such as nasal mucosal injury and hypoxemia. Furthermore, multimodal monitoring techniques including lung ultrasound will be employed to explore the physiological mechanisms by which HFNC maintains oxygenation stability through improving alveolar ventilation. Ultimately, this study seeks to establish an optimized, non-pressurized, low-risk oxygenation strategy for emergency pediatric patients with full stomachs, and to provide high-level evidence for reducing perioperative anesthesia-related complications in children.

干预措施:

运用HFNC预充氧后给予下颌支撑,停止辅助通气的同时,继续使用HFNC输送高流量氧,流量按对应体重亚组的统一标准设置(<18kg:<15kg 为 2L/(kg·min)、15-18kg 为 35L/min;≥18kg:18-30kg 为 35L/min、>30kg 为 40L/min)

干预措施代码:

Intervention:

After pre-oxygenation with HFNC, chin support is provided, and while assisted ventilation is discontinued, high?flow oxygen is continued via HFNC at flow rates set according to uniform standards for each weight subgroup: for patients <18 kg, those <15 kg receive 2 L/(kg·min) and those 15–18 kg receive 35 L/min; for patients >=18 kg, those 18–30 kg receive 35 L/min and those >30 kg receive 40 L/min.
