Which FAST examination assesses for intraperitoneal fluid in unstable trauma?

In unstable trauma, rapidly identifying intraperitoneal bleeding is the priority, and the FAST exam is designed for that purpose. It uses bedside ultrasound to look for free fluid in dependent areas of the abdominal cavity, like the hepatorenal and splenorenal recesses and the pelvis. Finding intraperitoneal free fluid in an unstable patient strongly suggests hemorrhage and helps decide if urgent surgery is needed. This approach is fastest and least invasive, can be performed right at the bedside during resuscitation, and can be repeated as the patient’s condition evolves. It’s preferred over CT abdomen, which requires transporting a unstable patient to radiology and delaying definitive care. DPL is invasive and less favorable compared with a quick, noninvasive ultrasound. MRI abdomen is not practical in the acute trauma setting due to time and accessibility.
