title: Effect of dialysate buffer on potassium removal during haemodialysis.
abstract: There is a linear relationship between potassium removal during haemodialysis and plasma potassium (Kp). Kp falls rapidly during the first hour of dialysis but very little during the last two hours of a five hour dialysis. There is a fairly constant movement of potassium from the intracellular to extracellular space throughout dialysis. Total potassium removal is best predicted by pre-dialysis Kp, but change in Kp is related to the impact of dialysis on acid-base status. The choice of acetate or bicarbonate buffered dialysate does not effect potassium removal during dialysis.
