Introduction
Thoracic Trauma
Penetrating Chest Injuries
* Majority are stab wounds or gunshot wounds (GSW)
* Lower mortality rates--less likely to include multiorgan injury
* 85% of penetrating chest wounds can be treated with tube thoracostomy and supportive measures
Penetrating Chest Trauma
* Wounds that enter or exit inferior to the nipple or the posterior tip of scapula may perforate the dome of the diaphragm.
* Any penetrating wound such as this should be considered to have an abdominal component until proven otherwise.
Penetrating Chest Trauma: Treatment
* ATLS protocol: A,B,C,D,E’s
* Emergency management
o Needle thoracentesis
o Tube thoracostomy
o Subxiphoid pericardotomy
o Video assisted thoracic surgery (VATS)
Work-up of Penetrating Chest Trauma
* Physical examination
o Look, Listen, Feel
o Contusions, diminished or absent breath sounds, SQ emphysema can readily be found
* CXR- best, least expensive and fastest initial evaluation
* Ultrasound-may soon replace CXR as initial radiographic study in chest trauma
* Angiography- to look for great vessel injuries
* CT Scan: for better evaluation of chest wall and parenchyma
* Transesophogeal Echocardiography
Penetrating Chest Injuries
* Operative intervention required for:
o Massive or persistent bleeding
o Massive air leak
o Tracheobronchial injuries
o Esophageal perforation
o Cardiac or great vessel injuries
o Post-traumatic empyema
* Wounds that enter or exit inferior to the nipple or the posterior tip of scapula may perforate the dome or the diaphragm.
* Any penetrating wound such as this should be considered to have an abdominal component until proven otherwise.
Penetrating Chest Trauma:Indications for Mechanical Ventilation
Intrapulmonary Foreign Bodies
* Bullets, fragments: indications for removal
Intrapulmonary Foreign Bodies
Pulmonary Parenchymal Laceration
High Velocity Missile Injuries
Blunt Chest Trauma
Categories of chest wall injuries
* Open pneumothorax
* Contusion and Hematoma
* Sternal fractures
* Scapular fractures
* Flail chest
* Intercostal vessel injury
Categories of Intra-thoracic Injuries
* Pulmonary
o Pneumothorax, hemothorax
o Pulmonary contusion
o Pulmonary laceration
* Vascular
o Great vessel disruption (Ao dissection, pulmonary vasculature)
* Cardiac
o Blunt Cardiac Injury, Penetrating injury
Work-up of Blunt Chest Trauma
* Physical examination
o Look, Listen, Feel
o Contusions, diminished or absent breath sounds, SQ emphysema can readily be found
* CXR- best, least expensive and fastest initial evaluation
* Ultrasound-may soon replace CXR as initial radiographic study in chest trauma
* Angiography- to look for great vessel injuries
* CT Scan: for better evaluation of chest wall and parenchyma
* Transesophogeal Echocardiography
Categories of chest wall injuries
* Contusion and hematoma
Categories of chest wall injuries
* Open pneumothorax
* Pneumothorax
