Study Notes

Trauma Management Pearls

Tracheobronchial injuries are common with blunt trauma and can present with symptoms like large continuous air-leak, persistent pneumothorax, and subcutaneous air.
Bronchus injuries occur more frequently on the right side and may require mainstem intubation on the unaffected side.
Diagnosis of tracheobronchial injuries is typically done through bronchoscopy, with 90% of injuries located within 1 cm of the carina.
Esophageal injuries can be challenging to diagnose, and diaphragm injuries are more likely to be found on the left side, often resulting from blunt trauma.
Aortic tears may not be evident on chest X-rays, so a high index of suspicion is necessary, especially in cases of significant trauma.
Initial treatment for aortic transection involves maintaining blood pressure between 100 and 120 mm Hg until definitive repair, identifying and treating other life-threatening injuries first.
For specific injuries, different operative approaches are utilized, such as median sternotomy for certain aortic and vascular injuries, left thoracotomy for specific arterial injuries, and midclavicular incision for distal right subclavian artery injuries.
Blunt cardiac injuries like myocardial contusion can be associated with sternal fractures and may present with arrhythmias such as V-tach and V-fib.
Aspiration may not immediately show on chest X-rays, and penetrating chest injuries require specific management based on the location and associated findings.
Traumatic causes of cardiogenic shock, such as cardiac tamponade, cardiac contusion, and tension pneumothorax, require prompt identification and management.
Sternal fractures and 1st and 2nd rib fractures are associated with high risks for cardiac contusion and aortic transection, respectively.
Pelvic fractures can lead to significant blood loss, and hemodynamically unstable patients with pelvic fractures may require stabilization and further intervention, such as embolization or pre-peritoneal packing.
