- 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 
- In children the chest wall is more pliable and there is often less morbidity unless there is also multiorgan trauma
Many of the following features can be seen on exam depending on the extent of the force.
- Upper-extremity cyanosis
- Bilateral subconjunctival hemorrhage
- Facial and neck edema
- Engorged tongue
Signs and Symptoms
- Chest wall bruising or significan tmechanism consistent with thoracic trauma (i.e. seatbelt sign, steering wheel deformity, airb deployment)
- Impaired blood flow to the brain can cause
- Maintain adequate oxygenation > 92%
- Maintain blood pressure with small fluid boluses if necessary (250cc boluses)
- Assess for tension pneumothorax if patient hypoxic or hypotensive
- Perform Needle thoracostomy if indicated
- Prepare for Advanced Airway if patient persistently hypoxic, unable to maintain airway, or has an anticipated poor clinical course
- Chest Xray
- CT with IV contrast for better assessment of lung and vasculature
