Anaphylaxis and Anesthesia: Controversies and New Insights
PERIOPERATIVE anaphylaxis may be a life threatening clinical condition and is typically a result of drugs or substances used for anesthesia or surgery. After anaphylaxis, allergologic assessment is essential to identify the offending agent and prevent recurrences, because no preemptive therapeutic strategies exist. This review seeks to (1) identify the clinical diagnostic pathway necessary to distinguish anaphylaxis from confounding clinical diagnoses, (2) discuss the more common allergens that cause anaphylaxis during anesthesia, (3) discuss a rational approach to the identification of the offending allergen through blood and skin testing that allows for the safe future clinical management of patients experiencing perioperative anaphylaxis, and (4) discuss new therapeutic perspectives for the management of patients whose hemodynamic collapse is unresponsive to catecholamines, the initial recommended pharmacologic intervention.
