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.
