Ketanserin in the treatment of protamine-induced pulmonary hypertension.
The reversal of heparin by protamine may cause severe hemodynamic deterioration, characterized by systemic hypotension, pulmonary hypertension, and bronchoconstriction. A case report is presented concerning the administration of ketanserin in the treatment of pulmonary vasoconstriction and right ventricular failure following the infusion of protamine in a patient undergoing coronary artery bypass surgery and mitral valve replacement. The potential role of serotonin in the development of this serious complication is discussed.
