Signs and Symptoms

  • Chest wall bruising or significan tmechanism consistent with thoracic trauma (i.e. seatbelt sign, steering wheel deformity, airb deployment)
  • Arrhythmia

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

Workup

  • Chest Xray
    • although often little diagnostic yield<ref>Cook AD, Klein JS, Rogers FB, et al. Chest radiographs of limited utility in the diagnosis of blunt traumatic aortic laceration. J Trauma. May 2001;50(5):843-7</ref
    • used to assess for gross Pneumothorax, Rib fracture, or mediastinal widening concerning for Aortic Dissection or Pulmonary Contusion
  • CT with IV contrast for better assessment of lung and vasculature
