A 0.6-Protamine/Heparin Ratio in Cardiac Surgery Is Associated With Decreased Transfusion of Blood Products
Goedhart et al. investigated the effect of different heparin/protamine ratios on the amount of blood transfusions following standard cardiac surgery. In the group of patients receiving 0.6/1 protamine/heparin ratio, the fraction of patients without the need of transfusion was higher and the total blood loss was lower compared to patients treated with a 0.8/1 protamine/heparin ratio. In their patient collective, the 0.6/1 protamine/ heparin ratio proved safe and superior.
