Ultrasound-based clinical diagnosis tools speed up the initial diagnosis of injury, reduce ionizing radiation in Computed tomography (CT) scans, and reduce medical costs. However, the role of Focused assessment with sonography in trauma (FAST) in the diagnosis of intra-abdominal injuries has not been well established. FAST is a rapid procedure and rapid information can be easily obtained in a hemodynamically unstable patient. FAST competes with CT scans in the diagnosis of intra-abdominal injuries; while it is not yet known whether FAST can be used as a tool to identify intra-abdominal injuries and eliminate the need for CT scan before laparotomy, as CT scans would not always be safe in unstable trauma patients.  In this narrative we evaluate literature of FAST in different medical situations following the blunt abdominal trauma. ‎ Advantages and disadvantages ‎of FAST was discoused for free fluid detection in abdomen and any solid organ injury.  Since clinical examination is not reliable to properly assess trauma patients and accepted gold standard methods such as CT scan and Diagnostic Peritoneal Lavage (DPL) are time consuming and invasive, FAST could provide reliable precision for treating hemodynamic patients unstable or more stable. be considered patient.
