Abstract
Function in 31 types of dialyser in vivo was evaluated from the clearance studies of urea, creatinine, uric acid and phosphate and the rate of ultrafiltration (UFR) under the condition of QB200ml/min, QD500ml/min and 250mmHg in transmembrane pressure. The dialyser with large surface area (1.8-2.5m2) has higher clearance of small molecules than the dialyser with standard surface area.Correlation between clearance of small molecules and UFR was high in dialyser with cuprophane membrane, but not always found in dialyser with other membrane material.
These results is considered to be dependent of membrane material and membrane thickness.
