Difficulty: HardTrauma and Burns

Match each trauma patient presentation with the most appropriate next step in acute management according to Advanced Trauma Life Support (ATLS) principles.

  • A 28-year-old with blunt abdominal trauma, blood pressure 75/40 mm Hg, and FAST exam showing hepatorenal free fluid.Immediate exploratory laparotomy
  • A 35-year-old with blunt abdominal trauma, blood pressure 115/75 mm Hg, and FAST exam showing splenorenal free fluid.Computed tomography (CT) of the abdomen with IV contrast
  • A 42-year-old with a fall from 20 feet, blood pressure 70/40 mm Hg, open-book pelvic fracture on X-ray, negative FAST exam, and unremitting shock after pelvic binder application.Retroperitoneal pelvic packing or angiographic embolization
  • A 22-year-old with a stab wound to the left parasternal border, blood pressure 80/40 mm Hg, and FAST exam showing an anechoic stripe around the heart.Emergency thoracotomy

Answer

Blunt + Unstable + FAST positive -> Laparotomy. Blunt + Stable + FAST positive -> CT scan. Pelvic fracture + Unstable + FAST negative -> Pelvic packing/angiography. Penetrating chest + Unstable + Pericardial fluid -> Thoracotomy.
Each presentation strictly follows Advanced Trauma Life Support (ATLS) algorithms, which prioritize identifying life-threatening hemorrhage and selecting interventions based directly on the patient's hemodynamic stability and ultrasound findings.

Step-by-Step Solution

1
Evaluate hemodynamic stability for each clinical presentation.
Patients 1, 3, and 4 are hemodynamically unstable (hypotensive); Patient 2 is hemodynamically stable.
Hemodynamic status dictates whether a trauma patient can safely undergo time-consuming imaging (like CT) or requires immediate intervention.
2
Determine the anatomic source of hemorrhage based on the mechanism, physical exam, and FAST results.
Patient 1 has intraperitoneal bleeding. Patient 2 has intraperitoneal bleeding. Patient 3 has retroperitoneal bleeding. Patient 4 has bleeding into the pericardial sac.
The anatomical space where blood is pooling dictates the specific surgical or interventional procedure required.
3
Apply the appropriate intervention algorithm.
Unstable intraperitoneal requires laparotomy; stable intraperitoneal requires CT; unstable retroperitoneal (pelvic) requires packing/embolization; unstable pericardial requires thoracotomy.
Following structured ATLS algorithms prevents delays in hemorrhage control and avoids inappropriate interventions (like laparotomy for a pelvic source).

Key Concept

Hemodynamic stability and the anatomic source of bleeding (identified via FAST and X-ray) dictate the algorithmic approach to acute trauma management.
