Live Stream of Prehospital Emergency Ultrasound in Patients With Acute Dyspnoea

Recruiting

• Conditions: Acute Dyspnea; Echocardiography
• Interventions: Other: Prehospital emergency ultrasound without tele-supervision; Other: Prehospital emergency ultrasound with tele-supervision

• Registration Number: NCT04817488
• Lead Sponsor: Medical University of Vienna

Brief Summary

Background: Acute dyspnoea is a common symptom in prehospital emergency medicine. As ultrasound gained in importance for diagnosis in patients with acute respiratory distress, it plays even a role in the prehospital setting. However, prehospital emergency ultrasound (PEU) remains challenging and requires knowledge and skills. New prehospital ultrasound devices offer the possibility for tele-supervision. The impact of tele-supervision of PEU in patients with acute dyspnoea is unclear.

Objective: This prospective observational study aims to evaluate the effect of PEU with tele-supervision on diagnosis, treatment strategies and cognitive load in comparison to PEU without tele-supervision in patients with acute dyspnoea.

Methods: In total 350 prehospital emergency patients with acute dyspnoea will be included in this study. Patients will be observed in two groups. In group 1 PEU will be performed with tele-supervision, whereas in group 2 PEU will be performed without tele-supervision (tele-supervision not available).
