Anaesthesia and intensive care
-
We describe a case of a patient undergoing open abdominal aneurysm surgery who developed a severe, life-threatening allergic reaction immediately after administration of sugammadex. The manifestation was purely a cardiovascular collapse. ⋯ Sugammadex was confirmed as the cause of the anaphylaxis by a positive intradermal allergy test (25 mm diameter response to 1:100 dilution), with a normal saline control and a negative response to the other drugs used during the event. This case report is a reminder that the use of sugammadex is associated with rare but serious risks.
