شرح Chest trauma , pneumothorax, haemothorax, flail chest 💯💫👌

Chest trauma refers to any physical injury to the chest, including the ribs, sternum, lungs, heart, and major blood vessels. It can be *blunt* (e.g., from car accidents, falls, or assaults) or *penetrating* (e.g., from gunshots or stabbings). Chest trauma is a leading cause of death in trauma patients due to potential damage to vital organs. *Common Types of Chest Trauma:* 1. *Rib Fractures* Most common chest injury. Can lead to complications like *pneumothorax* or **hemothorax**. *Flail chest* (≥3 adjacent ribs fractured in ≥2 places) can impair breathing. 2. *Pneumothorax* (Collapsed Lung) Air leaks into the pleural space, causing lung collapse. *Tension pneumothorax* is life-threatening (mediastinal shift, tracheal deviation, hypotension). Requires needle decompression or chest tube. 3. *Hemothorax* Blood accumulation in the pleural cavity. Can cause shock; may require chest tube drainage or surgery. 4. *Cardiac Injuries* *Myocardial contusion* (bruised heart muscle). *Cardiac tamponade* (blood in pericardial sac → Beck’s triad: hypotension, JVD, muffled heart sounds). Requires pericardiocentesis or thoracotomy. 5. *Aortic Injury (Traumatic Aortic Rupture)* Often due to high-speed deceleration (e.g., car crashes). May present with pulse discrepancies or widened mediastinum on X-ray. Surgical emergency. 6. *Pulmonary Contusion* Bruising of lung tissue → hypoxia, respiratory failure. Managed with oxygen, ventilation support. 7. *Diaphragmatic Rupture* Often missed; may lead to herniation of abdominal organs into the chest. Requires surgical repair. *Clinical Signs & Symptoms:* *Pain* (worsening with breathing or movement). *Dyspnea* (shortness of breath). *Hypotension* (shock due to bleeding or tamponade). *Crepitus* (subcutaneous emphysema from air leakage). *Jugular Vein Distension (JVD)* (tamponade or tension pneumothorax). *Decreased breath sounds* (pneumothorax/hemothorax). *Diagnosis:* *Chest X-ray* (initial screening). *CT scan* (more detailed, detects aortic injury, small pneumothorax). *FAST exam* (for pericardial fluid in tamponade). *ABG* (assess oxygenation). *Emergency Management:* 1. *ABCs (Airway, Breathing, Circulation)* Intubate if needed. High-flow oxygen. 2. *Needle Decompression* (for tension pneumothorax – 2nd intercostal space, midclavicular line). 3. *Chest Tube Insertion* (for large pneumothorax/hemothorax). 4. *Fluid Resuscitation & Blood Transfusion* (if hemorrhagic shock). 5. *Pericardiocentesis* (for tamponade). 6. *Surgery* (thoracotomy for major vascular injuries). *Complications:* *Respiratory failure* (due to flail chest, contusion). *Infection* (empyema after hemothorax). *ARDS* (acute respiratory distress syndrome). *Key Takeaway:* Chest trauma can be rapidly fatal. Early recognition and intervention (especially for **tension pneumothorax, cardiac tamponade, massive hemothorax**) are critical. Always reassess for evolving conditions.
