  Purpose
The main objective of our study is to compare the effects of two care strategies for dyspneic patients on the length of hospital stay: (1) standard care (=contextual analysis + conventional clinical chest radiography) versus (2) standard care + pleuropulmonary ultrasound.

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Prevention
Official Title: Evaluation of the Diagnostic Value of Portable Ultrasound for Dyspneic Patient Support in the Emergency Department: a Randomized Study

Arms Assigned Interventions
Active Comparator: Standard care

Patients randomized to this arm will receive standard care.

Intervention: Standard care.

Other: Standard care
Standard care for dyspneic patients including contextual analysis, conventional clinical exam and a chest X-Ray.
Experimental: Standard care + ultrasound

Patients randomized to this arm will receive standard care + pleuropulmonary ultrasound.

Intervention: Standard care + ultrasound

Other: Standard care
Standard care for dyspneic patients including contextual analysis, conventional clinical exam and a chest X-Ray.
Device: Vscan portable ultrasound device (GE Healthcare, Wauwatosa, WI)
Standard care (as described for the other intervention) + pleuropulmonary ultrasound using the Vscan portable ultrasound device (GE Healthcare, Wauwatosa, WI).

Detailed Description:

The secondary objectives of this study are to assess the following for both arms:

A-fatality rate, B-degree of concordance between the diagnosis orientation in the emergency department and final diagnosis determined by an expert committee using patient records one month later (blind evaluation by a panel of experts) C-clinical improvement between early emergency care and later care outside the emergency department (clinical parameters = blood gases and other biological parameters) D-imaging parameters.
