Difficulty: HardTrauma and Burns

Match each clinical presentation of a trauma patient with the most appropriate next step in definitive management or diagnostic workup.

  • A 24-year-old man with a stab wound to the anterior abdomen. His blood pressure is 80/40 mm Hg and heart rate is 130/min. Focused assessment with sonography for trauma (FAST) is negative.Immediate exploratory laparotomy
  • A 35-year-old woman involved in a high-speed motor vehicle collision. Her blood pressure is 115/75 mm Hg and heart rate is 95/min. FAST examination demonstrates free fluid in the right upper quadrant.Computed tomography (CT) of the abdomen and pelvis with intravenous contrast
  • A 42-year-old man with a severe pelvic crush injury from a workplace accident. His blood pressure is 75/40 mm Hg and heart rate is 135/min. FAST examination is negative for intraperitoneal fluid.Application of a pelvic binder and subsequent pelvic angiography
  • A 28-year-old woman with a gunshot wound to the left thigh. She has an expanding hematoma and an absent dorsalis pedis pulse. Her blood pressure is 115/75 mm Hg and heart rate is 105/min.Immediate operative vascular exploration

Answer

The unstable patient with a penetrating abdominal wound requires immediate exploratory laparotomy. The stable patient with blunt trauma and a positive FAST requires a CT scan. The unstable patient with a pelvic crush injury and negative FAST requires a pelvic binder and angiography. The patient with hard signs of vascular injury requires immediate operative vascular exploration.
The correct pairings rely on strict adherence to ATLS algorithms. Unstable penetrating abdominal injuries require laparotomy. Stable patients with positive FAST from blunt trauma undergo CT imaging to grade solid organ injuries. Unstable blunt pelvic injuries with negative FAST necessitate pelvic binding and angiography. Extremity wounds with hard signs of vascular injury require operative exploration.

Step-by-Step Solution

1
Analyze the mechanism of injury and hemodynamic status for each patient.
Patients 1 and 3 are hemodynamically unstable. Patients 2 and 4 are stable.
Hemodynamic stability is the critical branch point in determining whether a patient needs immediate operative intervention or further imaging.
2
Evaluate the unstable patients (1 and 3).
Patient 1 (penetrating abdominal wound) requires an immediate laparotomy. Patient 3 (blunt pelvic trauma with negative FAST) requires a pelvic binder and angiography to address retroperitoneal bleeding.
Unstable penetrating abdominal injuries bypass imaging. Unstable blunt injuries without intraperitoneal fluid (negative FAST) strongly suggest pelvic retroperitoneal hemorrhage.
3
Evaluate the stable patients (2 and 4).
Patient 2 (positive FAST) is stable, allowing for a CT scan. Patient 4 has 'hard signs' of vascular injury, necessitating immediate surgery despite stable vital signs.
Stable patients with positive FAST can be further evaluated to avoid unnecessary surgery. Hard signs of vascular injury always mandate immediate surgical exploration.

Key Concept

Advanced Trauma Life Support (ATLS) algorithms prioritize hemodynamic stability, mechanism of injury (blunt vs. penetrating), and the presence of hard signs to dictate the choice between immediate surgical intervention, mechanical stabilization, and advanced imaging.
