However, this can cause the development of antibiotic resistant strains of bacteria, so giving antibiotics without a clear need is normally discouraged. For people who are at especially high risk of developing infections, the sputum can be cultured to test for the presence of infection-causing bacteria; when they are present, antibiotics are used.Pain control is another means to facilitate the elimination of secretions. A chest wall injury can make coughing painful, increasing the likelihood that secretions will accumulate in the airways. Chest injuries also contribute to hypoventilation (inadequate breathing) because the chest wall movement involved in breathing adequately is painful. Insufficient expansion of the chest may lead to atelectasis, further reducing oxygenation of the blood. Analgesics (pain medications) can be given to reduce pain. Injection of anesthetics into nerves in the chest wall, called nerve blockade, is another approach to pain management; this does not depress respiration the way some pain medications can. Prognosis
Pulmonary contusion usually resolves itself without causing permanent complications; however it may also have long-term ill effects on respiratory function. Most contusions resolve in five to seven days after the injury. Signs detectable by radiography are usually gone within 10 days after the injury—when they are not, other conditions, such as pneumonia, are the likely cause. Chronic lung disease correlates with the size of the contusion and can interfere with an individuals ability to return to work.
Epidural hematoma is when bleeding occurs between the tough outer membrane covering the brain (dura mater) and the skull. Often there is loss of consciousness following a head injury, a brief regaining of consciousness, and then loss of consciousness again. Other symptoms may include headache, confusion, vomiting, and an inability to move parts of the body. Complications may include seizures.The cause is typically head injury that results in a break of the temporal bone and bleeding from the middle meningeal artery. Occasionally it can occur as a result of a bleeding disorder or blood vessel malformation. Diagnosis is typically by a CT scan or MRI. When this condition occurs in the spine it is known as a spinal epidural hematoma.Treatment is generally by urgent surgery in the form of a craniotomy or burr hole. Without treatment, death typically results. The condition occurs in one to four percent of head injuries. Typically it occurs in young adults. Males are more often affected than females. Signs and symptoms
Many people with epidural hematomas experience a lucid period immediately following the injury, with a delay before symptoms become evident. Because of this initial period of lucidity, it has been called "Talk and Die" syndrome. As blood accumulates, it starts to compress intracranial structures, which may impinge on the third cranial nerve, causing a fixed and dilated pupil on the side of the injury.
