Procedural oxygen mask versus high-flow nasal cannula to prevent low oxygen in children during upper GI endoscopy

Comparison of a Procedural Oxygen Mask and High-Flow Nasal Cannula for the Prevention of Hypoxemia During Pediatric Upper Gastrointestinal Endoscopy Under Sedation: A Single-Center Randomized Controlled Pilot Trial

NA · Kocaeli City Hospital · NCT07234188

This trial will test whether a procedural oxygen mask or a high-flow nasal cannula better prevents low oxygen levels in children aged 6 to 16 having sedated upper gastrointestinal endoscopy.

What this trial studies

This randomized pilot compares the procedural oxygen mask (POM™) with high-flow nasal cannula (HFNC) for preventing hypoxemia during sedated pediatric upper gastrointestinal endoscopy. Children aged 6–16 years, weighing more than 30 kg and classified as ASA I–II, who are scheduled for non-emergency procedures will be randomized to receive oxygen via POM or HFNC. Investigators will continuously monitor oxygen saturation and record desaturation events, airway interventions, and other safety outcomes during the procedure. The single-center trial at Kocaeli City Hospital aims to generate preliminary data to inform larger studies on optimal oxygen delivery in this setting.

Who should consider this trial

Good fit: Children aged 6–16 years, over 30 kg, ASA physical status I–II, scheduled for non-emergency sedated upper GI endoscopy with parental consent are the intended participants.

Not a fit: Children with known pulmonary or cardiac disease, oxygen dependency, recent intubation/ICU admission, tracheostomy, congenital airway or craniofacial anomalies, or those outside the age/weight criteria are excluded and likely will not benefit from this protocol.

Why it matters

Potential benefit: If successful, the study could reduce episodes of low oxygen during pediatric endoscopy and improve procedural safety by identifying the more effective oxygen delivery method.

How similar studies have performed: High-flow nasal cannula has shown reductions in desaturation in several pediatric respiratory and procedural settings, while randomized data on procedural oxygen masks specifically for pediatric endoscopy are limited, making this comparison partly novel.
