Evaluating High Flow Nasal Cannula Effects on Infants with Bronchiolitis

Evaluation of Pulmonary Aeration and Muscle Thickening Fraction in Infants With Bronchiolitis Using a High-flow Nasal Cannula: Association of Electrical Impedance Tomography and Ultrasound

Not applicable Interventional Hospital Israelita Albert Einstein · NCT06376487

This study is testing how different flow rates of High Flow Nasal Cannula can help infants under 2 with bronchiolitis by looking at their breathing and muscle function.

What this trial studies

This clinical study aims to assess how different flow rates of High Flow Nasal Cannula (HFNC) affect the thickening fraction of abdominal and diaphragm muscles in infants under 2 years old diagnosed with bronchiolitis. The study will utilize Electrical Impedance Tomography (EIT) to monitor changes in lung impedance and functional residual capacity (FRC) during varying flow rates. Continuous monitoring will be conducted in a pediatric ICU setting to gather data on respiratory distress and potential failure criteria for HFNC therapy.

Who should consider this trial

Good fit: Ideal candidates for this study are infants under 2 years old diagnosed with bronchiolitis who require HFNC treatment.

Not a fit: Patients with chronic diseases may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve the management of bronchiolitis in infants by optimizing HFNC therapy.

How similar studies have performed: While the approach of using EIT in this context is relatively novel, similar studies have shown promise in optimizing respiratory therapies.
