Focus Cardiac Ultrasound in Patients With Shock

Focus Cardiac Ultrasound in Patients With Undifferentiated Shock: Prospective Observational Study

The aim of this study is to analyze in patients with undifferentiated shock, the concordance of initial treatment before and after Focus cardiac ultrasound (FoCUS) in comparison with the reference one established by an adjudication committee

Focus cardiac ultrasound (FoCUS) has already demonstrated its ability to reduce diagnosis uncertainty in patients with undifferentiated shock. However, adequacy of initial treatment has not been investigated.

In patients with undifferentiated shock, after clinical evaluation, the physician states its hypothesis and initial treatment intention in closed list. He realizes a FoCUS, states another time the hypothesis and begins treatment according to FoCUS results. An adjudication committee with all the patient's file will state the reference hypothesis and treatment
