Pulmonary laceration is usually accompanied by hemoptysis (coughing up blood or of blood-stained sputum). [12] Thoracoscopy may be used in both diagnosis and treatment of pulmonary laceration. [8] A healing laceration may resemble a lung nodule on radiographs, but unlike pulmonary nodules, lacerations decrease in size over time on radiographs. [4]
Unlike pulmonary laceration, another type of lung injury, pulmonary contusion does not involve a cut or tear of the lung tissue. A pulmonary contusion is usually caused directly by blunt trauma but can also result from explosion injuries or a shock wave associated with penetrating trauma. With the use of explosives during World Wars I and II ...
A pneumatocele results when a lung laceration, a cut or tear in the lung tissue, fills with air. [4] A rupture of a small airway creates the air-filled cavity. [1] Pulmonary lacerations that fill with blood are called pulmonary hematomas. [4] In some cases, both pneumatoceles and hematomas exist in the same injured lung. [5]
Accompanying injuries often play a key role in the outcome. [10] Injuries that may accompany TBI include pulmonary contusion and laceration; and fractures of the sternum, ribs and clavicles. [2] Spinal cord injury, facial trauma, traumatic aortic rupture, injuries to the abdomen, lung, and head are present in 40–100%. [17]
Signs and symptoms of spontaneous subcutaneous emphysema vary based on the cause, but it is often associated with swelling of the neck and chest pain, and may also involve sore throat, neck pain, difficulty swallowing, wheezing and difficulty breathing. [5] Chest X-rays may show air in the mediastinum, the middle of the chest cavity. [5]
First, it’s important to understand that inflammation isn’t always bad. “Inflammation is one of the body’s key mechanisms for maintaining homeostasis, acting as a natural response to ...
Traumatic asphyxia is characterized by cyanosis in the upper extremities, neck, and head as well as petechiae in the conjunctiva. Patients can also display jugular venous distention and facial edema. [3] Associated injuries include pulmonary contusion, myocardial contusion, hemo/pneumothorax, and broken ribs. [4] [5]
Chest injuries account for 25% of all deaths from traumatic injury. [1] Typically chest injuries are caused by blunt mechanisms such as direct, indirect, compression, contusion, deceleration, or blasts [ 2 ] caused by motor vehicle collisions or penetrating mechanisms such as stabbings .
