Clinics in chest medicine

In the United States, trauma is the leading cause of death in people under 40 years of age. Chest trauma is a relatively common but potentially lethal injury and requires a high level of suspicion, rapid diagnosis, and appropriate therapy. Methods for the assessment, diagnosis, and treatment of chest trauma are discussed in this article.

Toxic inhalants cause injury through a variety of different mechanisms, including direct irritation of the respiratory tract mucosa, asphyxiation, and systemic absorption of the toxin. The nature and extent of the acute injury depends on the inhalant's water solubility, aerodynamic features, pH, and concentration. In addition, a patient's underlying respiratory function may affect the clinical response. ⋯ Chronic airflow obstruction has been reported in patients exposed to ammonia, chlorine, nitrogen dioxide, and sulfur dioxide; bronchiolitis obliterans may follow exposure to nitrogen dioxide and sulfur dioxide. Inhalation injuries can be difficult to manage because exposures occur infrequently, and the exact toxic agents involved often are not known immediately. Prevention of occupational exposures remains a cornerstone in the overall management of inhalation injuries.
