Using ultrasound to diagnose acute dyspnea in emergency departments

Evaluation of the Feasibility and Accuracy of an Ultrasound Algorithm for Acute Dyspnea Diagnosis in the Emergency Department

Not applicable Interventional Central Hospital, Nancy, France · NCT03691857

This study is testing a new ultrasound tool to see if it can help doctors in emergency rooms better diagnose the causes of sudden breathing problems like heart failure, pneumonia, and lung disease.

What this trial studies

This study evaluates a new ultrasound algorithm designed to improve the diagnosis of acute dyspnea in emergency departments. It focuses on three main causes of dyspnea: heart failure, pneumonia, and exacerbation of obstructive pulmonary disease. The algorithm's accuracy will be assessed by comparing ultrasound results with traditional diagnostic methods, and the feasibility of its implementation in emergency settings will also be evaluated. The study involves a multicenter approach, with ultrasound exams being conducted by trained physicians and analyzed by a centralized core laboratory.

Who should consider this trial

Good fit: Ideal candidates for this study are men and women aged 50 and older experiencing non-traumatic acute dyspnea in the emergency department.

Not a fit: Patients in cardiac arrest, persistent shock, or with severe cognitive impairment will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to faster and more accurate diagnoses of acute dyspnea, potentially reducing mortality rates associated with this condition.

How similar studies have performed: While the use of ultrasound in emergency settings is gaining traction, this specific algorithm for acute dyspnea diagnosis is relatively novel and has not been extensively tested in prior studies.
