eFAST (extended focused assessment with sonography for trauma) allows an emergency physician or a surgeon the ability to determine whether a patient has pneumothorax, hemothorax, pleural effusion, mass/tumor, or a lodged foreign body. The exam allows for visualization of the echogenic tissue, ribs, and lung tissue.
A hemothorax (derived from hemo-[blood] + thorax [chest], plural hemothoraces) is an accumulation of blood within the pleural cavity.The symptoms of a hemothorax may include chest pain and difficulty breathing, while the clinical signs may include reduced breath sounds on the affected side and a rapid heart rate.
Massive right sided pleural effusion later confirmed to be a hemothorax. Hemothorax, or accumulation of blood in the pleural space, can result from trauma or surgical procedures in the chest. This accumulation of blood can grow large enough to compress the lung and push away other structures in the chest, thus causing a mediastinal shift. [6]
A pleural effusion is accumulation of excessive fluid in the pleural space, the potential space that surrounds each lung.Under normal conditions, pleural fluid is secreted by the parietal pleural capillaries at a rate of 0.6 millilitre per kilogram weight per hour, and is cleared by lymphatic absorption leaving behind only 5–15 millilitres of fluid, which helps to maintain a functional ...
After an initial assessment involving basic checks on airway, breathing and circulation, the caregiver considers things like mechanism of injury (how the person was hurt) to determine if a more rapid diagnostic approach is indicated than might otherwise be used. A rapid trauma assessment should take no more than 90 seconds.
Vascular hemothorax is often caused by the rupture of the descending aorta. It initially occurs in the left pleural and mediastinal area due to the close vicinity of the pleural cavity. It is rare for a rupture of the thoracic aorta to result in a hemothorax, as the bleeding primarily occurs in the pericardial space.
The trauma triad of death is a medical term describing the combination of hypothermia, acidosis, and coagulopathy. [1] This combination is commonly seen in patients who have sustained severe traumatic injuries and results in a significant rise in the mortality rate. [2]
Half the time, initial X-rays are normal; in most of those that are not, hemothorax or pneumothorax is present. [4] A nasogastric tube from the stomach may appear on the film in the chest cavity; this sign is pathognomonic for diaphragmatic rupture, but it is rare. [4]
