Background

  • Traumatic asphyxia occurs when sudden and blunt chest trauma forces retrograde flow of blood through the superior vena cava and into the neck and head.
  • Normally a result of blunt chest trauma from an MVA [1]
  • In children the chest wall is more pliable and there is often less morbidity unless there is also multiorgan trauma[2]

Clinical Features

Many of the following features can be seen on exam depending on the extent of the force.[3]

  • Upper-extremity cyanosis
  • Bilateral subconjunctival hemorrhage
  • Facial and neck edema
  • Engorged tongue

Signs and Symptoms

Prehospital

  • Maintain adequate oxygenation > 92%
  • Maintain blood pressure with small fluid boluses if necessary (250cc boluses)
  • Assess for tension pneumothorax if patient hypoxic or hypotensive
  • Prepare for Advanced Airway if patient persistently hypoxic, unable to maintain airway, or has an anticipated poor clinical course
