VEXUS-REA : Evaluation of Ultrasound Parameters of Venous Congestion in Patients in a Medical Intensive Care Unit

Shock is a common and serious cause of admission to intensive care. Vascular filling is one of the cornerstones of shock treatment, aimed at increasing cardiac output and restoring adequate organ perfusion through rapid intravenous administration of a solution. However, this vascular filling can be accompanied by venous congestion, which can be harmful. Fluid administration must therefore be sparing and carefully considered. However, it is difficult to assess the correct amount of intravenous fluid to inject. Multi-site venous ultrasound (inferior vena cava, suprahepatic vein, portal vein, renal vein), recently published under a score called VExUS, could be a useful bedside tool for documenting venous congestion and avoiding excessive vascular filling. Nevertheless, this tool has been little evaluated in the general intensive care population, particularly in patients with acute respirat
