Thoracic trauma

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 ptx (avoid excess bagging)
• Place central lines on the SAME side as existing injury or PTX (prevent b/l ptx)
• Hypotensive resuscitation in chest trauma may be beneficial

DDx

1. Traumatic Pneumothorax
2. Tension Pneumothorax
3. Hemothorax
4. Flail Chest
5. Sternum Fracture
6. Traumatic Asphyxia
7. Trachobronchial Injury
8. Cardiac Tamponade
9. Myocardial Contusion

• w/ pnetrating chest inj neuro defecit should incr suspicion of vasc inj b/c nv bundle run together

• Aortic transection: pt often asx, but die w/o warning, 80% die at scene, hypotension NOT from ruptured aorta (just die). see wide sup mediastinum on cxr (>8cm on supine film), nd high suspicion to dx! ct gd for aorta not branch vessels, if high suspicion nd aortography, the gold stndrd, but 1/4 hve complications ie inf & hematoma. Rx= keep sbp <120 w/ a & b blockers.

• commotio cordis is most common cause of cardiac death in athlete. sudden death w/o abnl heart from trauma to cw at vent depolarization= vf & death.

• esophageal inj is rare but bad & hard dx to make. rx=controversial if no sx. suspect if L htx or ptx w/o rib fx, or pneumomediastinum, d/t incr pressure of low chest/abd= tear in esoph!
