Chest Trauma



Chest Trauma


  • A patient has inward movement of the right ribcage upon inspiration.
    • –Dx: Flail chest. >3 consecutive rib fractures
    • –Tx: O2 and pain control
  • A patient has confusion, petechial rash in chest, axilla and neck and acute SOB.
    • –Dx: Fat embolism
    • –When to suspect it: After long bone fx (esp femur)
  • A patient dies suddenly after a 3rd year medical student removes a central line.
    • –Dx: Air embolism
    • –When else to suspect it: Lung trauma, vent use, during heart vessel surgery

Emergent Chest Injuries



Hemothorax


Massive Hemothorax:

  • Presentation:
    • place chest tube and defined as >1000cc of immediate blood return or >200/hr for >2-4hrs
  • Management:
    • volume resuscitation followed by surgery to repair the site of bleeding

Rapid Deceleration Trauma


InjuryPresentationRisk FactorsAssociated
Aortic Disruptionaortic disruption who are seen in the ED usually have a contained hematoma w/in the adventitia
– laceration is the most common just proximal to the ligamentum arteriosum
Weak aortic wall:
Marfan’s syndrome
syphilis
Ehlers-Danlos syndrome
first and second rib, scapular, and sternal fractures

Flail Chest


DefinitionPresentationComplicationsManagement
three or more adjacent ribs fractured at 2 points, causing paradoxical inward movt of the flail segment w/ inspirationcrepitus and abnormal chest wall movt.
Abnormal chest wall movt may not be appreciated if pt is splinting b/c of pain
respiratory compromise due to underlying pulmonary contusionO2
narcotic analgesia
respiratory support
including intubation and mechanical ventilation
surgical fixation of chest wall is generally needed
