[Bronchial lobar obstruction from a sucralfate tablet: a rare cause of acute respiratory insufficiency].

We report two cases of patients with chronic respiratory disease who experienced an asphyxia after aspirating a sucralfate tablet that occluded a lobar bronchus. In adults, a foreign body is a rare cause of acute respiratory failure from tracheobronchial occlusion. The sucralfate tablet has the physical property of expanding rapidly when wet (contact with mucosa). After aspiration, the tablet expands to a larger size and can occlude a lobar bronchus, causing acute respiratory failure. In patients at risk of aspiration, we recommend the use of sucralfate in liquid or suspension form.
