Microcirculation During Haemodialysis

* SDF is validated by measuring changes in microcirculation in sepsis patients with MOF (Boerma studies). * SDF is validated by measuring changes in microcirculation in stable chronic hemodialysis patients (NDT 2009 Bemelmans). * Ultrafiltration in stable chronic hemodialysis leads to a decrease in sublingual microcirculatory flow (NDT 2009 Bemelmans). * Trendelenburg position improves the sublingual microcirculatory flow at the end of hemodialysis treatment (NDT 2009 Bemelmans). * Hemodialysis with ultrafiltration leads to a significant reduction of myocardial perfusion and cardiac output (NDT 2009 Dasselaar) * Cardiac output measurement during dialysis is not practical. * BVM is a validated method for hypotension due to ultrafiltration to prevent the amount of ultrafiltration online change based on the measured haemoconcentration (ref Dasselaar et al NDT 2005). * BCM is a validated measurement to the dry weight in hemodialysis patients measured by a bioimpedance technique (NDT Passauer et al 2009).
