What does the Focused Assessment with Sonography in Trauma (FAST) identify?

The Focused Assessment with Sonography in Trauma (FAST) is specifically designed to assess patients for intra-abdominal and pericardial fluid in the context of trauma. It utilizes ultrasound to quickly evaluate for the presence of free fluid, which is often a sign of bleeding, as well as assess for free air that might indicate perforation of hollow organs.

The procedure involves scanning multiple abdominal quadrants, the chest, and the pelvis to identify fluid collections that could arise from traumatic events. This rapid assessment allows medical personnel to make swift decisions regarding the need for further diagnostic imaging or immediate surgical intervention.

By focusing on fluid and air collections, FAST provides critical information that can guide treatment in trauma cases, particularly in emergency situations where time is of the essence. This capability makes it an essential practice in trauma care.
