Traumatic Pneumothorax • External chest / abdominal blunt / penetrating trauma tear a bronchus or abdominal viscus leakage air into pleural space
• Larynx, trachea and heart shifted toward unaffected side • Gurgling sounds synchronous with respiration open fistula connecting with air containing tissues

Evidence of tension: • Shift of mediastinal structure away from the side of air leak • Basis of evidence of: ▫ Circulatory compromise ▫ Hearing a”hiss” or rapid exit of the air with the insertion of thoracostomy tube

Tension Pneuothorax causes: • Limit expansion of contralateral lung • May compromise venous return
12
Definitive Treatment • Closed thoracotomy: ▫ Drainage trapped air through a catheter ▫ External opening in a dependent position under water adequate to re-expand the lung
• Open thoracotomy: ▫ Plication of blebs ▫ Closure of fistula ▫ Stripping of the pleura apical lung
• Thoracoscopy
