Heparin-coated equipment reduces complement activation during cardiopulmonary bypass in the pig.

Complement activation was studied during cardiopulmonary bypass (CPB) in the pig. One group of animals was perfused for 2 h using a standard extracorporeal circuit including a hollow fiber membrane oxygenator with full systemic heparinization. Another group was treated in the same way, except that bypass was performed through a heparin-coated CPB circuit… CONTINUE READING
