Intraoperative Cardiac Arrest due to Allergic Acute Coronary Syndrome (Kounis syndrome) Triggered by Cephalosporin

ABSTRACT

An acute coronary syndrome due to mast?cell activation in the presence of an allergen is known as Kounis Syndrome (KS). This relatively new entity of KS is being increasingly recognized among allergists, cardiologists, and emergency physicians; however, it is not well?known among anesthesiologists. We report here, a case of type 2 KS due to antibiotic administration causing sudden perioperative cardiac arrest.
