Comparing high-flow nasal cannula to standard nasal cannula during EBUS bronchoscopy

HFNC Versus Conventional Nasal Cannula During EBUS Procedure: a Randomised Controlled Trial

Not applicable Interventional The University Clinic of Pulmonary and Allergic Diseases Golnik · NCT06637280

This study tests if using a high-flow nasal cannula instead of a standard one helps adult patients get better oxygen during an endobronchial ultrasound bronchoscopy.

What this trial studies

This study aims to evaluate the effectiveness of high-flow nasal cannula compared to standard nasal cannula in preventing oxygen desaturation during endobronchial ultrasound (EBUS) bronchoscopy. Adult patients undergoing the procedure will be randomly assigned to receive either high-flow or standard oxygen supplementation. The primary objective is to determine if the high-flow method provides better oxygenation and reduces the risk of hypoxemia during the bronchoscopy. Both groups will undergo the same bronchoscopy procedure, with the only difference being the method of oxygen delivery.

Who should consider this trial

Good fit: Ideal candidates include adult patients over 18 years old with normal pre-procedural oxygen and carbon dioxide levels who are scheduled for EBUS bronchoscopy.

Not a fit: Patients who may not benefit include those with contraindications for bronchoscopy or high-flow nasal cannula, such as pregnancy or nasopharyngeal obstruction.

Why it matters

Potential benefit: If successful, this study could lead to improved oxygenation and safety for patients undergoing EBUS bronchoscopy.

How similar studies have performed: Other studies have shown promising results with high-flow nasal cannula in various settings, suggesting potential for success in this approach.
