Abstract

Patients with chronic renal failure undergoing hemodialysis (HD) need to receive adequate dialysis. Dialysis inadequacy leads to an increase in the side effects and even frequent hospitalizations as well as increased therapeutic costs. Considering the fact that improving the adequacy of dialysis is one of the goals of nursing care in these patients, this study aimed to compare the effect of linear and step-wise sodium-ultrafiltration (UF) profiling on HD adequacy. This study is a clinical trial; a total of 32 patients from two dialysis centers in East Azerbaijan province were selected and randomly divided into two groups. Each patient underwent HD for three sessions by routine method, three sessions by linear sodium profile and UF, and three sessions by the step-wise sodium profile and UF. At the end of each HD method, Kt/V was calculated to determine the adequacy of dialysis. Data analysis was performed using Statistical Package for the Social Sciences software version 13 with generalized estimating equation statistical test. According to the results of this study, there was a statistically significant difference between the mean of adequacy of dialysis (Kt/V) in the three treatment methods (P <0.05), in which the mean score of dialysis adequacy in step-wise method was 0.14 more than the routine method, and in the linear method, it was 0.21 more than the routine method. The mean Kt/V scores were 1.24, 1.31, and 1.10 in the step-wise method, linear method, and routine method, respectively(P <0.05). The results of this study indicate that simultaneous application of sodium and UF profiles is effective in the hemodynamic stability of patients, which reduces uncomfortable complications during dialysis. Therefore, in order to improve dialysis adequacy and prevent the complications, usage of sodium and UF profiles is recommended.
