Flail chest injuries often indicate severe intrathoracic damage, particularly lung contusions and chest collapses. Most patients require prolonged mechanical ventilation, highlighting the severity of this trauma.

Area of Science:

  • Trauma Surgery
  • Thoracic Medicine
  • Emergency Medicine

Background:

  • Flail chest is a severe consequence of blunt chest trauma.
  • It is associated with significant morbidity and mortality.
  • Understanding associated injuries is crucial for patient management.

Purpose of the Study:

  • To analyze the spectrum of intrathoracic injuries in patients with flail chest.
  • To determine the association of flail chest with specific injuries.
  • To evaluate outcomes including ventilation requirements, hospital stay, and mortality.

Main Methods:

  • Retrospective analysis of 92 patients with flail chest.
  • Comparison with a control group with simple rib fractures.
  • Data collection on associated injuries and treatment outcomes.

Main Results:

  • Pulmonary contusion (46%) and pneumothorax/hemothorax (70%) were common.
  • No increased incidence of great vessel, tracheobronchial, or diaphragmatic injuries.
  • 27% developed adult respiratory distress syndrome; 69% required prolonged mechanical ventilation (mean 22 days).
  • Mean hospital stay was 24 days; mortality rate was 33%.

Conclusions:

  • Flail chest is a marker for significant intrathoracic injury, especially pulmonary contusion and hemopneumothorax.
  • It is not a marker for great vessel, tracheobronchial, or diaphragmatic injuries.
  • High rates of prolonged mechanical ventilation and significant mortality underscore the severity of flail chest injuries.
