The infiltration of dilute epinephrine solution has been used for many years to provide hemostasis. However, epinephrine has adverse cardiovascular effects, such as arrhythmia, pulmonary edema, and even cardiac arrest. We have experienced epinephrine-induced cardiovascular crisis, with severe hypertension, tachycardia, and cardiac arrest after subcutaneous infiltration of a 2% lidocaine and 1 : 200,000 epinephrine solution in a patient with an asymptomatic subarachnoid hemorrhage. We provided successfully advanced cardiac life support in the operating room and cardioverted the patient back into a sinus rhythm with no untoward effects. The patient recovered without any apparent sequelae after intensive care.
