title: [Prevention of negative hemodynamic effects of protamine sulfate by simultaneous infusion of microdoses of adrenaline].
abstract: Two groups of coronary patients subjected to revascularization of the myocardium were examined in order to detect the negative hemodynamic effects of protamine sulfate (PS) and the possibility of their correction by simultaneous infusion of adrenaline microdoses. In group 1 (27 pts.) heparin was neutralized by infusion of PS alone (6 mg/kg) and in group 2 (27 pts.) by simultaneous infusion of PS and adrenaline (15 ng/kg/min). The functions of the right and left ventricles were evaluated by catheterization of the pulmonary artery by a Swan-Ganz catheter and transesophageal Doppler echocardiography. These methods provided volume and velocity characteristics of the right and left compartments of the heart. PS deteriorated the systolic function of the right ventricle, particularly in patients with initial dysfunction of the right heart. Infusion of adrenaline simultaneously with PS leveled its negative effects, thus preventing myocardial dysfunction.
