Randomized Controlled Trial Comparative Study Clinical Trial
Disparity in blood activation by two different heparin-coated cardiopulmonary bypass systems.
Several studies have indicated reduced "blood activation" in heparin-coated cardiopulmonary bypass systems. The present study compares the effect of two different heparin coatings on different blood activation indices. ⋯ Both heparin coatings reduce blood activation, probably more so with Carmeda Biological Active Surface than with Duraflo II.
