dc.description	La sobrehidratación presente en los pacientes nefrópatas es factor de riesgo de morbi-mortalidad, por lo que es importante su diagnóstico y tratamiento. Los vectores de impedancia bioeléctrica (VIBE), permiten realizar estimaciones objetivas del estado de hidratación. El objetivo de este estudio fue comparar la eficiencia de VIBE contra los parámetros clínicos convencionales para ajustar el ultrafiltrado y alcanzar el peso seco en pacientes en hemodiálisis.	es_ES
dc.description	The over-hydration in patients with nephropathy is a risk factor for morbidity and mortality, so its diagnosis and treatment is important. Bioelectrical impedance vectors (VIBA) allow objective estimates of hydration status. The purpose of this study was to compare the efficiency of VIBA against conventional clinical parameters to adjust the ultrafiltration and achieve dry weight in hemodialysis patients. The study included 47 adult patients who were randomized into two groups. In group A, the dry weight was adjusted according to BIVA to reach euhydration. In group B, the dry weight was adjusted according to conventional clinical parameters. Monthly measurements of bioelectrical impedance were performed in all patients pre and post hemodialysis for four months. At baseline, no significant differences between groups were found. The basal VIBA pre and post-hemodialysis indicated overhydration, with no significant differences between them. After four months of intervention, the vectors belonging to group A in the post-dialysis showed the achievement of dry weight, as opposed to post-dialysis vectors corresponding to group B , which remained in the bottom of the ellipses (p <0.009 A vs B). A significant difference at baseline and in final vectors in group A (p <0.001) was found. Clinical edema decreased (group A: 95.7% base line vs 0% final, group B: 83.3% base line vs 54.2% final, p <0.001). Initially, 82.6% and 95.8% of patients were overhydrated in group A and B respectively. The dry weight was achieved in 95.7% of patients in group A and 4.2% in group B. Analysis of BIVA is a useful tool to adjust dry weight in hemodialysis patients, being superior to clinical parameters commonly used for this purpose.	es_ES
