Acute Gastrointestinal (GI) Bleeding are a common chief complaint among Emergency Department. The mortality rate for Lower GI Bleeding is 3.9%. While the mortality rate can be as high as 10% for Upper GI Bleeding. Most existing scores take into account hemodynamic parameters such as systolic blood pressure or heart rate. Studies have shown that hemodynamic instability only develops late in the course of a bleed, as evidenced by a blood depletion of 30 to 40% of the total blood volume. Currently, few studies have examined the value of echocardiography in the management of patients presenting for Acute GI Bleeding in the Emergency Department. The main objective of this study is to show whether simple ultrasound parameters can, combined with clinico biological parameters, predict in an early manner the evolution of the patient presenting to the Emergency Department for Acute Gastrointestinal Bleeding.
