Seven parameters model study for adequacy of dialysis in a hemodialysis unit

Abstract

Two methods generally used to assess dialysis adequacy are URR and Kt/V . The Kt/V is more accurate than the URR in measuring how much urea is removed during dialysis, primarily because the Kt/V also considers the amount of urea removed with excess fluid.

Dialysis delivery should be adequate to not only improve quality of life and also to prolong survival. The aims of dialysis are thus, to decrease morbidity, improve quality of life and prolong life span. To achieve these aims, dialysis must be performed effectively, effective (HD) is one of important factors that plays a role in decreasing morbidity and mortality of patients, and ineffective dialysis is one of factors causing high mortality of these patients.There are many surveys that indicate the relationship between dose of dialysis and mortality of patients; they concluded that inadequate dose of dialysis increase duration of hospitalization and overall cost of care and complications.

Hemodialysis can only be adequate when all symptoms and signs of uremia are eradicated, the patient is fully rehabilitated and the kidney failure does not interrupt activities of daily living. From clinical perspective, probably the best marker of adequacy is a physically active, well nourished, non-anemic, normotensive with no complaint .
