DIETARY SALT RESTRICTION AND REDUCTION OF DIALYSATE SODIUM TO CONTROL HYPERTENSION IN MAINTENANCE HAEMODIALYSIS PATIENTS

Abstract

This study was conducted on thirty hypertensive haemodialysis patients with controlled dry weight. They were divided into 2 groups: the 1'1 group subjected to dietary Na reduction and gradual reduction of

dialysate Na and the 2"d group without reduction. All patients were subjected to x-ray chest echocardiography and analysis ofNa, K, Ca, Ph, urea, creatinine and CBC. It was found a significant lowering of pre-dialysis and post-dialysis mean blood pressure in 151 group as compared to 2"d group. Also, we found significant reduction of serum Na (P=0.023) in the

1'1 group as coll!pared to 2"d group.

In addition, there was significant correlation in echocardiography left ventricular end diastolic, ejection fraction and left atrial diameter findings and chest x-ray. No significant correlation was found between the two groups as regards calcium, phosphorous, potassium, urea, creatinine and complete blood count, We concluded that control of hypertension in hemodialysis patients by dietary Na reduction and low dialysate Na is effective. It is also recommended to fUI1her study the correlation of other factor such as anaemia) uremic toxins, and using low dialysate Na in controlling hypertension.
