Difficulty: HardTrauma and Burns

Match each trauma patient presentation with the most appropriate definitive next step in management. Assume airway and breathing have been secured in all patients.

  • Hemodynamically unstable patient with blunt abdominal trauma, negative FAST scan, and a mechanically stabilized open-book pelvic fracture.Pelvic angiography with embolization
  • Hemodynamically unstable patient with blunt trauma and positive FAST scan demonstrating significant free fluid in the hepatorenal recess.Exploratory laparotomy
  • Hemodynamically stable patient with blunt trauma, mild left upper quadrant tenderness, and positive FAST scan demonstrating a small amount of perisplenic fluid.Computed tomography (CT) scan of the abdomen and pelvis with intravenous contrast
  • Hemodynamically unstable patient with a penetrating parasternal stab wound, distended neck veins, and positive FAST scan demonstrating pericardial fluid.Surgical exploration via median sternotomy or anterolateral thoracotomy

Answer

Unstable patient with negative FAST and pelvic fracture -> Pelvic angiography. Unstable patient with positive FAST (intraabdominal) -> Exploratory laparotomy. Stable patient with positive FAST -> CT scan. Unstable patient with positive FAST (pericardial) -> Median sternotomy or thoracotomy.
The correct matches strictly adhere to ATLS protocols. Hemodynamic instability with intraabdominal fluid requires laparotomy, whereas instability with pericardial fluid requires sternotomy/thoracotomy. Stable patients can safely undergo CT imaging. Unstable patients with pelvic fractures and negative FAST scans require angiography to manage retroperitoneal arterial bleeding.

Step-by-Step Solution

1
Assess the patient's hemodynamic status.
Identify whether the patient is hemodynamically stable or unstable, as this dictates the urgency and type of the next intervention.
Hemodynamically unstable patients cannot tolerate the delays or the physical environment of the CT scanner and require immediate bedside or operative intervention.
2
Interpret the Focused Assessment with Sonography for Trauma (FAST) results in the context of stability.
A positive FAST in an unstable patient mandates immediate surgery (laparotomy for abdominal fluid, sternotomy/thoracotomy for pericardial fluid).
FAST rapidly identifies life-threatening hemorrhage or tamponade that is actively causing shock.
3
Evaluate the management of pelvic fractures with concurrent shock.
Recognize that a negative FAST in an unstable patient with a pelvic fracture strongly suggests retroperitoneal bleeding, which is not addressable via laparotomy.
Laparotomy releases the retroperitoneal tamponade effect, potentially worsening hemorrhage. These patients need mechanical stabilization followed by angiography.
