Basics

Description

  • Transfer of kinetic energy to the lung, causing direct damage to the lung parenchyma, resulting in both hemorrhage and edema in the absence of a pulmonary laceration
  • Mortality rate is 10–25%.
  • Independent risk factor for:
    • Acute respiratory distress syndrome
    • Pneumonia
    • Long-term respiratory dysfunction

Pathophysiology

  • Development of pulmonary contusion:
    • Takes place in 2 stages:
      • 1st stage, which is related to the direct injury, results in disruption of the alveolocapillary membrane, which leads to extravasation of blood into the interstitial and alveolar space.
      • 2nd stage is related to the indirect worsening of the injury as a result of measures that occur during the resuscitation of the patient, in particular, administration of IV fluids.
  • Leads to:
    • Increased intrapulmonary shunting
    • Increased resistance to airflow
    • Decreased lung compliance
    • Increased respiratory work
    • Hypoxemia and acidosis
    • Respiratory failure

Etiology

  • Blunt or penetrating thoracic trauma
  • Sudden deceleration–compression
  • Fall from height
  • Motor vehicle accident
  • Assault
  • Missile
