Abstract
Background: Fluid overload increases the risk of cardiovascular events and all-cause mortality in hemodialysis patients. Remote dielectric sensing (ReDS) is a newly wearable device which can evaluate the volumetric status via the ratio of fluid and air in pulmonary tissue. In this study we explored whether ReDS can be used in evaluation of volume status in dialysis patients.
Methods: We involved maintenance hemodialysis patients in the cross-sectional study and obtained both pre- and post-dialysis ReDS values. We also collected pre- and post-dialysis over hydration values by bioelectrical impedance analysis and biochemistry indicators like brain natriuretic peptide and analyzed their correlations with ReDS values to explore whether ReDS was feasible in fluid assessment for hemodialysis patients.
Results: 115 maintenance hemodialysis patients were enrolled. The average pre-dialysis ReDS reading was 27.47% ± 4.88% (range from 16.00% to 39.00%), and the median post-dialysis ReDS value was 24% (range from 16% to 37%). ReDS can distinguish fluid overload patients (pre-dialysis over hydration value≥2.5L, p<0.001). ReDS value has a positive correlation with over hydration value (pre-dialysis: R=0.38, p<0.001) and a negative correlation with left ventricular ejection fraction (R=-0.333, p=0.018). ROC analysis showed that cut-off of pre-dialysis ReDS value to discriminate pre-dialysis over hydration value≥2.5L was 26.5%.
Conclusion: ReDS has potential in fluid evaluation for maintenance hemodialysis patients and can serve as a useful tool to assist in clinical hydration status assessment.
期刊介绍:
Practical information on hemodialysis, hemofiltration, peritoneal dialysis and apheresis is featured in this journal. Recognizing the critical importance of equipment and procedures, particular emphasis has been placed on reports, drawn from a wide range of fields, describing technical advances and improvements in methodology. Papers reflect the search for cost-effective solutions which increase not only patient survival but also patient comfort and disease improvement through prevention or correction of undesirable effects. Advances in vascular access and blood anticoagulation, problems associated with exposure of blood to foreign surfaces and acute-care nephrology, including continuous therapies, also receive attention. Nephrologists, internists, intensivists and hospital staff involved in dialysis, apheresis and immunoadsorption for acute and chronic solid organ failure will find this journal useful and informative. ''Blood Purification'' also serves as a platform for multidisciplinary experiences involving nephrologists, cardiologists and critical care physicians in order to expand the level of interaction between different disciplines and specialities.
