Laryngeal angioedema resulting from use of an angiotensin-converting enzyme inhibitor (ACEI) is a dangerous medical condition that can lead to significant morbidity and mortality. Of the patients presenting to hospitals with angioedema, 39% to 46% are taking an ACEI. Contributing to an increased frequency of ACEI-induced angioedema is the fact that stopping ACEI therapy does not seem to prevent the recurrence of angioedema. As more patients have received ACEI therapy, the incidence of angioedema and resultant difficult airway has increased. Thus, critical care providers must know what to do when a patient has ACEI-induced angioedema and a difficult airway.
