Background

  • Must determine if injury also traverses the diaphragm (intra-abdominal injury)
    • Most deaths in thoracic trauma pts are due to noncardiothoracic injuries
  • Excessive PPV can lead to reduced venous return, tension pneumothorax (avoid excess bagging)
  • Place central lines on the SAME side as existing injury or pneumothorax (prevent bilateral pneumothorax)
  • Hypotensive resuscitation in chest trauma may be beneficial

Clinical Features

Inspection

  • Seat-belt sign indicates possible deceleration or vascular injury
  • Paradoxical wall movemement indicates flail chest
  • Distended neck veins
    • Tamponade, tension ptx, heart failure
  • Swollen face
    • SVC compression vs subcutaneous emphysema

Palpation

  • Neck
    • Trachea midline or displaced
  • Chest wall
    • Localized tenderness or crepitus due to rib fx or subcutaneous emphysema
  • Sternum
    • Localized tenderness, crepitus, or mobile segment suggests fx

Differential Diagnosis

Thoracic Trauma

Diagnosis

Imaging

  • Ultrasound
    • Can dx hemothorax, pneumothorax, tamponade, rib fx, sternum fx
  • CXR
    • Can dx hemothorax, pneumothorax, rib fx, pulmonary contusion, diaphragmatic rupture
    • Frequently underestimates the severity/extent of chest trauma
  • CT
    • Gold-standard

Complications

Aspiration

  • Common after severe trauma, esp of pt was unconscious at any time
  • Radiologic changes may be delayed up to 24hr (consolidation)
    • Due to chemical pneumonitis from gastric contents
  • No evidence to support prophylactic antibiotics to prevent pulmonary infection

Systemic air embolism

  • Pts w/ penetrating chest wounds who require PPV are at risk
  • May lead to dysrhythmias or CVA
  • Treatment
    • 100% NRB

Disposition

  • Asymptomatic thoracic stab wound
    • Repeat CXR in 4-6hr; if not delayed ptx seen pt can be discharged
