Traumatic hemothorax

Hemothorax is called hemothorax in the pleural cavity. The incidence of traumatic hemothorax accounts for 25% to 75% of blunt chest injuries and 60% to 80% of penetrating injuries. The treatment of traumatic hemothorax is designed to prevent shock, remove pleural hemorrhage early to relieve lung and mediastinal compression and prevent infection. The clinical manifestations of traumatic hemothorax depend on the amount and speed of bleeding and the severity of the associated injury. Acute blood loss can cause decreased circulating blood volume and decreased cardiac output. A large amount of blood can compress the lungs and mediastinum, causing respiratory and circulatory dysfunction. A small amount of blood in the thorax means that the volume of blood in the chest is below 500 ml, and the patient has no obvious symptoms and signs.
