Rates of heparin adsorption in hemoperfusion devices.
In vitro studies have shown that the rates of adsorption of heparin from saline in commercially available hemoperfusion devices at 100 to 200 ml/min flow rates are intrinsically quite low. Thus the potential for significant heparin removal from blood (and thus a rise in the possibility of clotting problems) in clinical applications seems remote.
