[Electroencephalographic changes in children dialyzed according to various protocols].

A study of electroencephalographic changes in six children during hemodialysis sessions was done in order to evaluate the effects of four different dialysis strategies: acetate or bicarbonate dialysates (sodium 142 mEq/1), acetate dialysate with high sodium concentration (148-150 mEq/1), and hemodiafiltration. There are basic activity alterations in all cases except during bicarbonate dialysis sessions. Alterations are, however, less pronounced during dialysis sessions with high sodium concentration dialysate. No strict concordance between clinical manifestations and electroencephalographic changes was observed. However, better tolerance of bicarbonate dialysis sessions is assessed with respect to clinical symptoms as well as electroencephalograms.
