RODRIGUEZ CABRERA, MJ. et al. Assessment of the average dose of dialysis with the On line Clarification Monitor (OCM) and the Daugirdas 93 Kt/v: Its practical application in a hemodialysis unit. Rev Soc Esp Enferm Nefrol [online]. 2004, vol.7, n.1, pp.50-54. ISSN 1139-1375.

Introduction: The morbimortality rate of patients undergoing hemodialysis treatment depends on, among other things, age, base illness and the quality of treatment. The Kt/V index is the reference parameter for the measurement of the dose of dialysis. The method of ionic dialysis (OCM, FMC) determines the Kt/V in real time, by clarifying the electrolytes. The objective of this study was theevaluation of the relationship between average Kt/V by OCM and by the Daugirdas 93. Material and Methods: 24 anuric patients were studied, of ages 64.75 ±18.24, 16.7% women and 20.8% diabetics. The membranes used were highly permeable polysulsphone (1.8m2) and helixone(1.4m2) The calculation of the Kt/V by the Daugirdas 93 was carried out in accordance with NFK-DO-QI and that of the OCM was determined in the intermediate session for 3 consecutive weeks. The data were processed with the SPSS 11.0 using lineal regression, analysis of the variables and t-student. p<0.05 was considered statistically significant. The Bland-Altman test was used to validate the method. Results: The OCM has a close relation to theKt/V of Daugeris 93 (1.29±0.2 vs. 1.32±0.2,p<0.001, r2=0.96, SEE: 0.08). The Bland-Alt-man test showed r2=0.05. We did not find significant differences in the other parameters. Conclusions: The average dose determined by OCM correlates with the Kt/V of Daugirdas 93.Its application, which does not involve excessive work, permits adequate control of dialysis. It improves the quality of treatment and consequently diminishes the morbimortality rate.
