Effect of Renal Haemodialysis on the Concentration of Sodium and Potassium

Abstract

In this study, 80 patients (47 men and 33 women) of different ages, with chronic renal failure on heamodialysis were selected to asses the effect of dialysis on the concentration of plasma electrolytes (sodium & potassium). All patients were seen at Khartoum Center for Dialysis and Kidney Transplantation. Tow samples from each patient were taken, pre and post dialysis. Then the concentration of plasma electrolytes (sodium & potassium), were estimated so as to know the impact (influence) of the renal heamodialysis on the concentration of sodium and potassium. And 20 healthy volunteer samples for comparison. The study show that, the concentration of sodium was not affected by the dialysis, and remain in the normal range before and after heamodialysis. on the other hand the concentration of potassium was found to be more affected by heamodialysis, was remarkably high before dialysis and significantly reduced after the dialysis. The prelimary studies showed most of patients were presented with other diseases such as hypertension, diabetes millets and hepatitis B virus, renal stones and tuber culosis. From this study the age of chronic renal failure patients had no effect on the concentration of sodium after the heamodialysis while the potassium concentration ‫‪was affected by the age, it was found to be more reduced‬‬ ‫.‪in age group of more than 30 years‬‬
