[27] [43] [44] The X-ray appearance of pulmonary contusion is similar to that of aspiration, [32] and the presence of hemothorax or pneumothorax may obscure the contusion on a radiograph. [25] Signs of contusion that progress after 48 hours post-injury are likely to be actually due to aspiration, pneumonia, or ARDS. [10]
Blood also can collect in the pleural space. This is called hemothorax. The most common cause is injury to the chest from blunt force or surgery on the heart or chest. Hemothorax also can occur in people with lung or pleural cancer. Hemothorax can put pressure on the lung and force it to collapse.
Infant prematurity is the factor most commonly associated with pulmonary hemorrhage. Other associated factors are those that predisposed to perinatal asphyxia or bleeding disorders, including toxemia of pregnancy, maternal cocaine use, erythroblastosis fetalis, breech delivery, hypothermia, infection (like pulmonary tuberculosis), Infant respiratory distress syndrome (IRDS), administration of ...
Symptoms are often unreliable, but include severe tearing chest pain; cough; dyspnea (shortness of breath); dysphagia (difficulty swallowing); back pain; and hoarseness. Blood pressure is usually high in the upper body, but low in the lower body. A widened mediastinum and a massive left hemothorax are often found in an X-ray.
Treatment for this condition is the same as for hemothorax and pneumothorax independently: by tube thoracostomy, the insertion of a chest drain through an incision made between the ribs, into the intercostal space. A chest tube must be inserted to drain blood and air from the pleural space so it can return to a state of negative pressure and ...
Traumatic cardiac arrest (TCA) is a condition in which the heart has ceased to beat due to blunt or penetrating trauma, such as a stab wound to the thoracic area. [1] It is a medical emergency which will always result in death without prompt advanced medical care.
Catamenial pneumothorax is the most common form of thoracic endometriosis syndrome, which also includes catamenial hemothorax, catamenial hemoptysis, catamenial hemothorax and endometriosis lung nodules, as well as some exceptional presentations. [12] [13]
