hemothorax
Accumulation of blood in the pleural space, typically following trauma or surgical procedures.
Full Definition
Hemothorax is the presence of blood in the pleural space, most commonly resulting from chest trauma, iatrogenic injury during thoracic procedures, or spontaneous bleeding in patients with coagulation disorders. The condition is classified by volume: small (<300 mL), moderate (300-1500 mL), or large (>1500 mL). Clinical presentation includes chest pain, dyspnea, and hemodynamic compromise in severe cases. Treatment typically involves chest tube drainage, with surgical exploration (thoracotomy or VATS) indicated for massive hemothorax, retained clot, or ongoing bleeding exceeding 200 mL/hour.
Usage
Usage note: Quantify volume when documenting; distinguish from hemopneumothorax.
