[Polymeric sorbents for hemoperfusion]

Applications of various sorbents and ion-exchange resins to hemoperfusion are reviewed. With respect to the type of processes accompanying removal of toxines from blood, the fillings of hemoperfusion columns are classified into the group of: sorbents, iono-sorbents and ion-exchangers, immunoadsorbents. Possibilities of improving hemocompatibility of polymeric materials used in hemoperfusion columns by a sorptive or covalent covering their surfaces with natural materials-heparin and/or albumin are discussed.
