Adding Urea to the Final Dialysis Fluid

ESRD Clinical Trial

Official title: Adding Urea to the Final Dialysis Fluid in Order to Prevent Dialysis Disequilibrium in Patients Who Need Aggressive Dialysis for Electrolyte Abnormalities

Status Not yet recruiting

Clinical Trial Summary

At times patients with advanced renal failure present with severe hyperkalemia or acidosis and very high serum blood urea nitrogen (BUN) concentrations. These patients cannot be dialyzed aggressively as the lowering of serum BUN may results in disequilibrium syndrome but on the other hand they need aggressive dialysis in order to lower their serum potassium or fix their severe acidosis. If one is able to add urea to the dialysis fluid, one can prevent the rapid lowering of serum BUN and osmolality at the same time as doing aggressive dialysis to lower serum potassium and/or fix the metabolic acidosis.

Clinical Trial Description

Ure-Na 15 gram tablets would be used to add to the dialysis fluid How much urea to add would be a simple calculation based on the 45X dialysis system and the patients serum urea concentration. The dialysate fluid urea concentration would be made to be about 15-40 mg/dL lower than the serum concentration. The patients labs/vitals and symptoms would be closely monitored throughout the dialysis treatment. ;
