A Case of Acute Lung Injury Caused by Inhalation of Industrial Acetic Acid

Abstract

Industrial exposure to toxic agent may produce a wide variety of respiratory damage. Acetic acid is a colorless liquid with a pungent vingar-like odor. It is a rare case that acute lung injury is caused by inhalation of acetic acid. Acetic acid is miscible with water, and may directly produce damage to mucosa of respiratory tract due to its irritant quality. The outcome of the reaction is dependent on the intensity and duration of exposure and varies from death or pulmonary edema in acute phase to resolution or bronchiolitis obliterans or bronchiectasis. We experienced a rose of acute lung injury due to accidental inhalation of acetic acid. The patient was a 31-year-old male who had developed progressive chest discomfort, chilling sense, and mild dyspnea after accidental inhalation of acetic acid. He had severe hypoxemia and chest radiograph showed diane bilateral alveolar edema. He responded to conservative treatment with oxygen inhalation and was discharged with improved condition on the 7th hospital day.
