Hemoperfusion in chronic uremia

Hemoperfusion is a blood purification technique involving direct contact between blood and adsorbent substances (sorbents). There are three basic kinds of sorbent: activated charcoal, immunoadsorbents, resins. Following our previous experience on charcoal hemoperfusion, a new coated anionic exchange...

Summary:Hemoperfusion is a blood purification technique involving direct contact between blood and adsorbent substances (sorbents). There are three basic kinds of sorbent: activated charcoal, immunoadsorbents, resins. Following our previous experience on charcoal hemoperfusion, a new coated anionic exchange resin for blood purification specifically designed to remove phosphates was experimentally employed in animals. 3 pigs, in which uremia had been surgically induced, underwent 6 extracorporeal hemoperfusion sessions (2 per pig) with a cartridge containing 100 gr of resin. The phosphate clearance proved satisfactory, values being 120 ml/min after 10' and around 80 ml/min after 2 hours. The biocompatibility of the resin and of the coating membrane was satisfactory. The negligible variation in pH and plasma bicarbonate during all sessions confirmed the low absorption by the tested resin of other blood anions competing with phosphate.
