Two Case of Stress Induced Cardiomyopathy after Injection of Epinephrine during Middle Ear Surgery / 대한이비인후과학회지

ABSTRACT

Epinephrine is a common use to control bleeding for wide surgeon's range of vision during surgery. However, it may be occurred with some major complications such as reversible cardiomyopathy, pulmonary edema, and cardiac arrest. Stress-induced cardiomyopathy (SIC) is a reversible cardiomyopathy, which is related with sudden surge of catecholamine such as epinephrine, and increase of physical activity and emotional stress. It has been postulated that SIC is a relatively uncommon syndrome with difficult definition. But recently SIC is an increasingly recognized disease entity and is accepted as a unique form of reversible cardiomyopathy. However, SIC rarely is occurred when standard dose of epinephrine is used during a surgery under general anesthesia. Therefore, we presented two patients with SIC after subcutaneous injection of epinephrine during middle ear surgery.
