Thoracic Surgical Emergencies Flashcards
3 traumatic thoracic emergencies
tension pneumo
- hemothorax
- diaphragm injuries
non traumatic thoracic emergencies
esophageal perforation
pneumothorax
air in the pleural space
tension pneumothorax
positive intrapleural pressure
- accumulated intrapleural air cannot flow back into the bronchial tree. collapse of lung, air is pulled into pleural space causing accumulation and mediastinum+heart deviation
- impared venous return leads to hypotension
presentation of tension pneumothorax
any trauma patient with hemodynamic instability. Decreased breath sounds on injured side.
- hyper-resonance on inmaging.
- venous distension of neck veins.
JVP change in tensino pneumo
JVP- right atrial pressure. JVP would be higher because pressure in thoracic cavity and lungs is greater. At the same time, there is overall hypo- tension because the heart cannot function properly and overall there is poor perfusion to the rest of the body.
note X ray findings of tension pneumo
treatment of tension pneumo
don’t wait for XRAY. this is a clinical diagnosis. he needs chest tube but initial needle decompression. plus ABCs
hemothorax
definition: blood in the pleural space. source of beleding can be from chest wall, lung, heart/great vessels, diaphragm, intra-abdominal organs spleen/liver
diagnostic method for hemothoax
CXR. beware supine CXR can miss large effusions.
treatment of hemothorax
- drainage of blood from pleural space–> chest tube.
- control of bleeding
- most pts with blunt trauma/stab will stop bleeding. but you may need surgery if you’ve drained over 1500 ccs of blood.
causes of diaphragmatic injury
- penetrating
- blunt trauma( multiple rib fractures esp on L side)
diagnostic CXR findings of diaphragm injuries
• Diagnosis
– Can be difficult to detect
• CXR
– Elevated hemidiaphragm /indistinct
– NG appears in chest / Hollow viscous in chest •
CT Scan with Coronal Reconstruction
– Now test of choice
treatment for injury to diaphragm
- surgical repair: natural history of undiagnosed is enlargement)
- thoracotomy for chronic injury
