Introduction: Changes in plasma sodium concentration (pNa, expressed in mEq/L) are common in hemodialysis (HD) patients. Hemodialysis monitors can estimate pNa by using an internal algorithm based on ion dialysance measurements. The present study studies the accuracy of the correlation between the pNa estimated by the dialysis monitor and that measured by the biochemistry laboratory at our center. Material and methods: A single-centre prospective observational study in patients on a chronic HD program with the 6008 CAREsystem monitor and standard sodium (138 mmol/L) and bicarbonate (32 mmol/L) prescriptions. Venous blood samples were drawn from each patient before and after each HD session to ensure inter- and intra-individual validity. The pNa was measured in the biochemistry laboratory using indirect potentiometry and simultaneously the estimated pNa by the HD monitor was recorded at the beginning and at the end of the HD session. For statistical analysis, a scatterplot was made, and Spearman’s correlation quotient was calculated. In addition, the differences between both methods were represented as Bland-Altman diagrams. Results: The pre-dialysis pNa measured in the laboratory was 137.49 ± 3.3, and that of the monitor, 137.96 ± 2.91, with a correlation with R2 value of 0.683 (p |
