“…Guirao et al [10] found that during CRRT, the venous extracorporeal circulation line pressure of the bedside hemo ltration machine was negatively correlated with the service time of supporting pipes and lters. Ejaz et al [11] suggested that the reduced mean lter lifespan was related to abnormal blood ow (hemodialysis catheter dysfunction).…”

Objective To investigate the effects of different filtration fractions (FFs) during daytime continuous venovenous hemodiafiltration (CVVHDF) post-dilution. Methods From April to December 2021, forty patients who received CVVHDF in the Second Affiliated Hospital of Nanchang University were randomly assigned to the low FF group (FF: 20–25%) or the high FF group (FF: 25–30%) and then compared with each other. The lifespan of the extracorporeal circuit and other performance metrics were compared between the two groups. Results During treatment, there was no statistically significant difference in arterial pressure between the two groups at 2 hours, 6 hours and the end of treatment compared with that at 1 hour of treatment (P = 0.30, 0.27, 0.87). There was no statistically significant difference between the venous pressure at 2 hours, 6 hours and the end of treatment compared with that at 1 hour of treatment (P = 0.55, 0.53, 0.53), and there was also no statistically significant difference in transmembrane pressure (P = 0.55, 0.63, 0.53). There was no statistically significant difference in the clotted filter or the extracorporeal circulation circuit at the end of CRRT between the two groups (P = 0.95, 0.31). There were statistically significant differences in the clearance efficiency of serum creatinine (P = 0.04). Conclusion For patients with daytime CRRT, CVVHDF treatment with FFs < 25% compared with FFs of 25–30% has no statistically significant difference in the risk of coagulation during cardiopulmonary bypass, while the efficacy seems to be significantly different. This study aims to provide supportive data for the criteria for defining FF in clinical practice.

“…El lugar óptimo de inserción vendrá determinado por el riesgo de trombosis e infección y la habilidad técnica del médico que los coloca. De esta manera se utiliza frecuentemente la vía femoral y la vía yugular derecha evitando la subclavia para largas permanencias por el elevado riesgo de estenosis (9,11) .…”

“…Además, la monitorización continua del Kuf (cada 8 horas), su descenso nos indicará una pérdida de superficie efectiva de la membrana. De ahí que una monitorización frecuente nos permita conocer el estado del hemofiltro y una anticipación a la coagulación del mismo (9,11) . El valor de referencia del Kuf para un determinado hemofiltro lo proporciona el propio fabricante, a partir del mismo veremos su progresión descendente.…”

Carretera del Prat nº 32 5º 1ª 08038 Barcelona 2 RESUMEN El fracaso renal agudo afecta a un 25% de los pacientes hospitalizados en las Unidades de Cuidados Intensivos. A pesar de los avances tecnológicos, la mortalidad de estos pacientes sigue siendo elevada debido a las complicaciones asociadas. Uno de los tratamientos del fracaso renal agudo son las técnicas continuas de reemplazo renal ya que permiten tratar las complicaciones y disminuir la mortalidad. El conocimiento y la habilidad de la enfermera en relación a estas técnicas serán decisivos para el éxito de la terapia. Para ello, la formación y la experiencia de la enfermera son el componente clave. El presente artículo tiene como objetivo actualizar los conocimientos sobre las técnicas continuas de reemplazo renal. Para ello se realiza una revisión de los principios físico-químicos como la difusión y la convección, entre otros; una descripción de las modalidades de las técnicas continúas de reemplazo renal; una presentación de los principales accesos vasculares; y una descripción de los cuidados enfermeros y de las complicaciones relacionadas con las técnicas utilizadas.Palabras claves: cuidados intensivos, hemodiálisis, hemodiafiltración, hemofiltración, cuidados de enfermería, complicaciones, lesión renal aguda, acceso vascular ABSTRACTAcute renal failure affects 25% of patients hospitalized in intensive care units. Despite technological advances, the mortality of these patients is still high due to complications associated. One of the treatments of acute renal failure are continuous renal replacement techniques because they allow complications management and decrease mortality. Nurse's knowledge and skills in relation to these techniques will be critical for therapy success. Consequently, nurse experience and training are key components. The objective of this article is to update the knowledge about continuous renal replacement techniques. This is a review of phisical and chemical principles as difussion and convection, among others; description of different continuous renal replacement techniques; description of main vascular access; description of nursing cares and complications related to applied techniques.
