Limited ultrasound examination directed solely at identifying the presence of free intraperitoneal or pericardial fluid. Indicated in trauma patients presenting with a history of abdominal trauma, are hypotensive, or are unable to provide a reliable history because of impaired consciousness due to head injury or drugs and is used as decision making tool for identifying the need for laparotomy. FAST is performed at the end of the ATLS primary survey. refl.in/jj
