    Abstract:
    The effects of prostacycline (PGI2), the most powerful known platelet antiaggregant on platelet count and function during cardiopulmonary bypass, were assessed in a double blind study. One group of 13 patients received 2,5 mg/Kg of Heparin with an infusion of 25 ng/Kg/min of prostacycline instituted 15 minutes before the Heparin, continued at the beginning of cardiopulmonary bypass at a dose of 50 ng/Kg/min and terminated at the end of bypass. A second group of 15 patients were studied by the same protocol with a placebo infusion. The platelet count was significantly higher at the end of cardiopulmonary bypass in the Prostacycline group. Platelet aggregation was reduced by comparison with the control group from the beginning of Prostacycline infusion. The active thrombin time was significantly longer in the Prostacycline group. However, blood loss did not differ significantly between the two groups although it was less in the study group. The platelet count and function during cardiopulmonary bypass with Prostacycline was therefore increased and resulted in a reduction in Heparin consumption.
