Diagnosis

ATLS Blunt Abdominal Trauma Algorithm

• Unstable
  • FAST to search for free fluid (vs. DPL if unavailable)
    • Positive: Exploratory laparotomy
    • Negative: CT scan
• Stable
  • CT scan
    • Exploratory laparotomy, angiographic embolization, conservative management as indicated

Management

• Nonoperative management is successful in >90% of pts who are hemodynamically stable
• Low-grade injuries (grades I–III) can almost always be managed without surgery
  • Higher-grade injuries commonly fail nonoperative therapy.
• Consider angiographic embolization if:
  • Large amount of hemoperitoneum
  • Vascular injury (contrast blush) on CT
