To evaluate the usefulness of Focused Assessment with Sonography for Trauma in diagnostic of blunt abdominal trauma patients and to bring attention to patients with pelvic fracture who should receive additional tests for the presence of peritoneal fluid.

An analysis of high-quality evidence resources was performed, limited to the articles published since 2005 year.

99 articles were found during the search, of which 23 were accurate. 16 articles were based on original research.

Focused Assessment with Sonography for Trauma plays a key role in the investigation of blunt abdominal trauma and should be used in all emergency departments. FAST-negative patients can remain under observation except major pelvic injury patients. The evaluation of peritoneal fluid in this group has low sensitivity.
