Using High-Flow Nasal Cannula to Prevent Low Oxygen During Anesthesia Intubation in Children Aged 2 to 10 Years A Randomized Controlled Trial

What this Trial Is About

This research aims to evaluate the use of high-flow nasal cannula HFNC oxygen therapy to prevent low oxygen levels hypoxemia during anesthesia-induced tracheal intubation in children aged 2 to 10 years. Children have higher metabolic needs and are more likely to experience airway collapse and low oxygen during intubation compared to adults. Because spontaneous breathing stops at anesthesia induction, oxygen is rapidly used up, increasing the risk of serious complications. Ultrasound is also used to help diagnose stomach swelling during the procedure. Participants are randomly assigned to one of two groups. In the HFNC group, after the child stops breathing spontaneously, mask ventilation is done until oxygen levels reach 90%, then the mask is removed and HFNC oxygen is provided through nasal tubes to maintain oxygen during apnea. Intubation or laryngeal mask placement is performed afterward while HFNC continues. The control group receives no intervention. The study uses the AIRVO2 device for HFNC and monitors apnea time between 2 to 10 minutes. During the study, researchers will assess how long children can safely hold their breath without oxygen drops and monitor oxygen levels throughout the procedure. Children are evaluated for lung and heart health, cooperation, and anesthesia risk level before participation. The study includes triple masking to reduce bias and will run until November 2025. Safety and oxygenation effectiveness during intubation are the main focuses, with follow-up occurring during the perioperative period.
