Pulmonary contusion results in bleeding and fluid leakage into lung tissue, which can become stiffened and lose its normal elasticity. The water content of the lung increases over the first 72 hours after injury, potentially leading to frank pulmonary edema in more serious cases. [ 20 ]
This typically results in chest pain that is worse with inspiration. [1] Bruising may occur at the site of the break. [3] When several ribs are broken in several places a flail chest results. [4] Potential complications include a pneumothorax, pulmonary contusion, and pneumonia. [2] [1]
Flail chest is usually accompanied by a pulmonary contusion, a bruise of the lung tissue that can interfere with blood oxygenation. [5] Often, it is the contusion, not the flail segment, that is the main cause of respiratory problems in people with both injuries. [6] Surgery to fix the fractures appears to result in better outcomes. [7]
Associated injuries include pulmonary contusion, myocardial contusion, hemo/pneumothorax, and broken ribs. [4] [5] Causes.
Management is a mixture of medical (eg pain relief, respiratory support, chest drainage and antibiotics), non-medical (physiotherapy and rehabilitation) and surgical (fixation of rib fractures if appropriate and operative treatment of cardiac, lung, airway, diaphragm and oesophageal injuries).
The differential diagnosis for ground-glass opacities is broad. General etiologies include infections, interstitial lung diseases, pulmonary edema, pulmonary hemorrhage, and neoplasm. A correlation of imaging with a patient's clinical features is useful in narrowing the diagnosis. [6] [7] GGOs can be seen in normal lungs. Upon expiration there ...
Blast lung refers to severe pulmonary contusion, bleeding or swelling with damage to alveoli and blood vessels, or a combination of these. [6] It is the most common cause of death among people who initially survive an explosion. [7]
Pulmonary laceration invariably results in pneumothorax (due to torn airways), hemothorax (due to torn blood vessels), or a hemopneumothorax (with both blood and air in the chest cavity). [11] Unlike hemothoraces that occur due to pulmonary contusion, those due to lung laceration may be large and long lasting. [12]
