- 1st step → FAST; Diagnostic peritoneal lavage is rarely done
- If patient is stable, CT scan can determine the specific location of the hematoma
- Pelvis & abdomen can hold enough blood to cause hemodynamic shock


- FAST determines if there is bleeding; assesses free fluid in the pericardium, spleen, liver/kidney, and bladder
- 1st step → FAST; Diagnostic peritoneal lavage is rarely done
- If patient is stable, CT scan can determine the specific location of the hematoma
- Surgery indicated in uncontrolled hemorrhage (symptoms of shock) or organ rupture (positive peritoneal findings)
- Pelvis & abdomen can hold enough blood to cause hemodynamic shock
- This vignette used to present a hemodynamically stable patient, making FAST incorrect. The vignette was recently altered to present an unstable patient (Dec 2025)
