Using ultrasound to predict failure of high-flow nasal cannula therapy

Ultrasound Evaluations of Diaphragm and Intercostal Muscle to Predict the Failure of High-Flow Nasal Cannula Therapy

Observational Shanghai Zhongshan Hospital · NCT06375538

This study is testing if ultrasound can help doctors see how well certain muscles are working to predict if patients will struggle with high-flow nasal cannula oxygen therapy in the first day of treatment.

What this trial studies

This observational study evaluates diaphragm and intercostal muscle contractions using ultrasound to predict the failure of high-flow nasal cannula oxygenation therapy within the first 24 hours of treatment. By assessing muscle function, the study aims to identify patients who may not respond well to this therapy. The findings could help clinicians make timely decisions regarding patient management and intervention. The study is conducted at Shanghai Zhongshan Hospital.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 years old who require high-flow nasal cannula oxygenation therapy.

Not a fit: Patients who have received mechanical ventilation recently, have neuromuscular disorders, or are pregnant may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance patient outcomes by allowing for early identification of those at risk of therapy failure.

How similar studies have performed: While similar approaches have been explored, this specific use of ultrasound for predicting therapy failure is relatively novel.
