Hemothorax is the presence of blood in the pleural space. The source of blood may be the chest wall, lung parenchyma, heart, or great vessels. The condition is usually a consequence of blunt or penetrating trauma. It may also be a complication of several diseases or may be iatrogenically induced.
Normally, the pleural space, which is between the parietal and visceral pleurae, is only a potential space. Air or fluid in the space may compromise lung expansion. Blood in the pleural space can be associated with both hemorrhagic shock and respiratory compromise; it must be effectively evacuated to prevent complications such as fibrothorax and empyema.
In a 34-month period at a large level-one trauma center, 2086 children younger than 15 years were admitted with blunt or penetrating trauma; 104 (4.4%) had thoracic trauma.1 Of the patients with thoracic trauma, 15 had hemopneumothorax (26.7% mortality rate), and 14 had hemothorax (57.1% mortality rate). Many of these patients had other severe extrathoracic injuries. Nontraumatic hemothorax carries a much lower mortality rate.
In another series of children with penetrating chest injuries (ie, stab or gunshot wounds), the morbidity rate was 8.51% (8 of 94).2 Complications included atelectasis (3), intrathoracic hematoma (3), wound infection (3), pneumonia (2), air leak for more than 5 days (2), and septicemia (1). Note that these statistics apply only to traumatic hemothorax.
