In blunt trauma, which bedside tool is most useful for rapid detection of intra-abdominal bleeding?

Explanation:
Focused Assessment with Sonography in Trauma (FAST) is designed for rapid bedside detection of free intraperitoneal fluid, which often signals intra-abdominal bleeding after blunt trauma. It can be performed within minutes right at the patient’s side, making it ideal for unstable patients who need immediate decisions about management. Being noninvasive, repeatable, and free of radiation, FAST allows quick confirmation of potential hemorrhage and helps determine whether to pursue operative exploration or additional imaging. In contrast, computed tomography provides a detailed, highly accurate assessment but requires patient transport to the scanner and time for contrast administration, which can delay treatment in an unstable patient. MRI is impractical in an emergency setting due to longer imaging times and availability. Diagnostic peritoneal lavage, while once common, is invasive and less favored because FAST offers rapid, safer bedside assessment.
