What is a hemothorax?
An accumulation of blood in the pleural space from injury to the chest wall, diaphragm, lung, blood vessels, or mediastinum.
What causes hemothorax?
Injury to one of these areas (not necessarily all): chest wall, lungs, mediastinum, or blood vessels.
Why does hemothorax cause respiratory distress?
Blood in the pleural space pushes lung tissue up, preventing full expansion.
Why is tachycardia seen in hemothorax?
Compensatory response to impaired oxygenation and blood loss.
Why is pain common in hemothorax?
Ongoing bleeding and tissue injury.
What happens to breath sounds in hemothorax?
Decreased or absent breath sounds on the affected side.
How does percussion differ: hemothorax vs pneumothorax?
Hemothorax: dullness (fluid/blood). Pneumothorax: hyperresonance (air).
What oxygenation change occurs in hemothorax?
Hypoxia due to reduced lung expansion and gas exchange.
What hemodynamic change is typical in hemothorax?
Hypotension from blood loss (not typically seen early in pneumothorax).
What key history/physical findings suggest hemothorax?
Trauma history, decreased lung sounds, percussion dullness (vs hyperresonance in PTX).
What does chest X-ray show in hemothorax vs pneumothorax?
Hemothorax: area may appear whited out (fluid). Pneumothorax: more black/air (negative space).
What other imaging helps diagnose hemothorax?
CT chest; bedside chest ultrasound (rapid trauma assessment for pleural fluid).
Primary treatment for hemothorax?
Chest tube insertion to drain blood and re-expand lung.
What is autotransfusion in hemothorax?
Recycling the patient’s blood collected via chest tube back into circulation.
Key respiratory assessments for hemothorax nursing care?
Assess rate, depth, ease of breathing; watch for signs of distress; auscultate lungs; monitor SpO₂.
Preferred positioning for hemothorax patients?
Semi-Fowler’s or High-Fowler’s to ease breathing.
Why encourage frequent repositioning in hemothorax?
Reduce pressure ulcer risk, promote lung expansion, and help prevent blood clots.
Why encourage deep breathing and early mobility with a chest tube?
Improves ventilation/expansion and prevents muscle atrophy; chest tube is not a reason to avoid movement.
What is a chylothorax?
Lymphatic fluid in the pleural space due to lymphatic system damage, usually from trauma or malignancy.
What history can point toward chylothorax?
History of lung cancer (malignancy-related lymphatic disruption).
Chylothorax clinical manifestations?
Severe cough, chest pain, difficulty breathing.
Chylothorax diagnostics (key points)?
H&P (duration of cough/dyspnea), lung sounds, chest X-ray.
First-line procedural treatment for chylothorax?
Drainage via thoracentesis (remove pleural fluid into vacuum chambers).
Why isn’t thoracentesis used to rapidly remove blood in hemothorax?
Rapid removal of blood can trigger cardiac arrest; prefer controlled drainage via chest tube.
