Effect of magnesium gradient concentration between plasma and dialysate on magnesium variations induced by hemodialysis.
The magnesium gradient concentration between plasma and dialysate was found to be the main factor responsible for the magnesium decrease induced by hemodialysis with a high-flux membrane using a dialysate magnesium concentration of 0.76 mmol.l-1. The changes in magnesium were negatively correlated to the predialysate magnesium concentration difference between plasma and dialysate. The magnesium changes tended to be less pronounced in the presence of an intradialysate protein increase greater than 9.6 g.l-1, reflecting loss of plasma water by ultrafiltration.
