Heparin-Bonded Cardiopulmonary Bypass Circuits Reduce the Rate of Red Blood Cell Transfusion During Elective Coronary Artery Bypass Surgery

Conclusions: The heparin-bonded cardiopulmonary bypass-treated patients in this study received fewer pRBCs than did the control group. A nonsignificant reduction in the pRBC transfusion rate was found between those with heparin-bonded bypass circuits and those with standard circuits who received ϵ-aminocaproic acid.
