FAST - Focused Assessment With Sonography In Trauma
The first integrated POCUS
Used to be “focused abdominal sonography in trauma”
>>> Now Focused Assessment with Sonography in trauma
Includes peritoneal, pelvic, thoracic, and pericardial spaces
Looking for fluid, presumed to be blood, in these sites
Narration
EFAST – ExtendedFocused Assessment With Sonography In Trauma
EFAST or extended FAST adds thoracic spaces for pneumothorax
Narration
EFAST – ExtendedFocused Assessment With Sonography In Trauma
The best initial imaging modality in trauma
Performed as part of primary or secondary survey in trauma
No ionizing radiation
Repeatable
Sensitive for significant fluid (typically, near 100% sensitive for 500cc or more)
Not meant to replace CT
Narration
EFAST – Probe Selection
Narration
Blunt Trauma – Morison’s Pouch
Right flank, coronal plane, indicator to head
Interrogate entire area including liver tip
Most sensitive place for fluid
Even with splenic rupture
Is position dependent – may take time laying flat to accumulate here
May detect as little as 200cc fluid
Sensitivity very high for 500cc+
