Treatment of Vasodilatory Shock after Cardiac Surgery:Low Dose Arginine Vasopressin Therapy: Three cases report / 대한흉부외과학회지

The vasodilatory shock after cardiopulmonary bypass is defined as the condition involving severe and persistent form of hypotension, tachycardia, normal or increased cardiac output and decreased systemic vascular resistance. Because of the unsuccessful response to infusion of fluids or catecholamine vasopressors, a sustained systemic shock state occurs and results in a high morbidity and mortality. We successfully treated this syndrome of 3 patients after open heart surgery with low dose of arginine vasopressin(AVP). Therefore,we report these cases with a review of related articles.
