The extended-focused assessment with sonography in trauma is still recognized as a technique approach to patients whose trauma involves the chest and the abdomen, with the aim of ruling out conditions as pneumothorax, hemothorax, pericardial effusion/cardiac tamponade, and intraperitoneal free fluid. Although CT is the gold standard test, the inconvenience of moving unstable patients and the amount of time it takes to carry it out, makes it not always possible in the Emergency Department, which positions the ultrasound as an ideal tool in the evaluation of patients with trauma in the Emergency Department. In this case report, we presented the case of a patient who complains of multiple stab wounds, and the extended-focused assessment with sonography in trauma confirmed the diagnostic impressions.
