Serum chromatographic pattern in different dialysis strategies.
In different dialysis strategies (hemodialysis with Gambro 1.5 m2, RP6 1 m2, Vita 2 1.2 m2), sequential ultrafiltration with RP 6 (1 hour ultrafiltration followed by 3 hours of hemodialysis and hemoperfusion with Absorba 300 C) serum chromatographic pattern and medium size molecules were studied with Sephadex G 15 chromatography. The removal of the studied medium size molecules is not different from one dialyzer to another. Serum levels were generally halved by the dialysis. In the ultrafiltration fluid a considerable amount of medium size molecules was found. There is no difference between RP 6 in open or in closed system. The absorbing capacity of the Absorba 300 C was blocked after one hour for medium size molecules in the patient under study.
