N/A kidney disease. Intervention 1: Patients in the control group treated with routine method (sodium dialysis solution 138 meq per liter in total duration of dialysis) for three sessions of dialysis and then both intervention and control groups for a week routine dialysis were (Wash Out) using cross over of patients in the two groups will change and both groups for one week (three days) dialysis will be in both patients twice a week dialysis during the three sessions of dialysis evaluated fall. Intervention 2: Intervention group patients on hemodialysis with the gradual reduction of sodium dialysis solution (starting with 150 meq per liter and cut it every 15 minutes, and then maintain this concentration) for one week (three days) will be dialysis. Both intervention and control groups for a week routine dialysis were (Wash Out) then using a cross over of patients in both groups will change and both groups for one week (three days) Dialysis and will both groups of patients who are on dialysis twice a week during the three sessions of dialysis evaluated.
