Occupational decompression sickness: A case report.

Decompression sickness describes the clinical pathology that ensues when rapid decompression from a highly pressurized environment causes the formation of venous and extravascular inert gas bubbles. Symptoms vary widely, commonly including arthralgias, myalgias, paresthesias, and numbness. Severe and potentially life-threatening pathology, such as neurologic impairment, cardiopulmonary instability, and gastrointestinal hemorrhage, can occur as well. Most think of diving endeavors as a common exposure predisposing to this condition, commonly referred to as "the bends." Other occupational exposures documented in the medical literature include military training, caisson work, such as in mining and bridge construction, and hyperbaric treatment attendance. This article presents the case of a 32-year-old male presenting with a mottled rash, arthralgias, myalgias, headache, vision changes, and weakness, which is found to have decompression sickness secondary to occupational exposure in a factory-based pressurized chamber. The patient underwent two hyperbaric chamber sessions with complete resolution of his symptoms. During hospitalization, he was found to have a patent foramen ovale. The patient was counseled to avoid further occupational exposure.
