为了阐明膜表面、膜组成、透析液缓冲液和对流传递对透析去除无机磷酸盐(Pi)的影响，对11名尿毒症患者进行了研究。每个患者都接受了 7 种不同的透析技术：使用醋酸盐缓冲液和不同表面或膜成分的传统血液透析、碳酸氢盐透析和“软”血液透析滤过（也称为生物滤过），稀释后输注 4 升。治疗时间固定为4小时。我们的研究表明，透析器表面积和超滤速率是透析无机磷（Pi）去除的主要因素。透析液缓冲液不会改变透析 Pi 的去除，但可能会影响反弹现象。
In order to clarify the influence of membrane surface, membrane composition, dialysate buffer and convective transfer on the dialytic removal of inorganic phosphate (Pi), 11 uremic patients were studied. Each patient underwent 7 different dialysis techniques: conventional hemodialysis with acetate buffer and different surface or composition of the membrane, bicarbonate dialysis and a “soft” hemodiafiltration, also termed biofiltration, with post-dilution infusion of 4 liters. The treatment time was fixed at 4 hours. Our study showed that the dialyzer surface area and the ultrafiltration rate were the major factors in dialytic inorganic phosphorus (Pi) removal. The dialysate buffer does not modify dialytic Pi removal but may influence the rebound phenomenon.
