Evaluating choking risk in stroke patients using laryngeal ultrasound

Evaluating Potential Risk of Choking by Laryngeal Ultrasound in Patients With Acute Stroke

Not applicable Interventional National Taiwan University Hospital · NCT04874454

This study tests if using a safe ultrasound can help doctors see how well stroke patients can swallow and if they are at risk of choking or getting pneumonia.

What this trial studies

This study assesses vocal cord movement in patients who have experienced an acute stroke using non-invasive laryngeal ultrasound. It aims to identify the risk of choking and aspiration pneumonia by monitoring these patients over the course of one year following their stroke. Current evaluation methods for swallowing function have limitations, and this study seeks to provide a safer alternative to traditional tests that may increase aspiration risk. By utilizing ultrasound, the researchers hope to improve the assessment of swallowing function in stroke patients.

Who should consider this trial

Good fit: Ideal candidates for this study are patients who have experienced an acute stroke within the past month.

Not a fit: Patients who had a stroke more than one month ago will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to safer and more effective evaluations of swallowing function in stroke patients, potentially reducing the incidence of aspiration pneumonia.

How similar studies have performed: While the use of laryngeal ultrasound is a novel approach in this context, similar non-invasive methods have shown promise in other studies.
