Ultrafiltration may be considered for patients with refractory congestion not responding to medical therapy (Level of Evidence: C) (Yancy, 2013). Hemodialysis (HD) with ultrafiltration (UF) in chronic renal replacement therapy is associated with hemodynamic instability, morbidity and mortality. "Continuous ultrafiltration therapy for temporary (up to 8 hours) or extended (longer than 8 hours in patients who require hospitalization) use in adult and pediatric patients weighing 20 kilograms or more whose fluid overload is unresponsive to medical management, including The advantage of this treatment is that haemodynamic parameters remain stable in the presence of significant removal of fluid Findings In this secondary analysis of a randomized clinical trial involving 1434 critically ill patients treated with continuous venovenous hemodiafiltration, a net ultrafiltration rate greater than 1.75 mL/kg/h compared with a net ultrafiltration rate less than 1.01 mL/kg/h was significantly associated with lower 90-day risk-adjusted survival. Renal replacement therapy, as with any medical therapy is not without risks. It is the less expensive but more sensitive to pollution due to its manufacturing process. Do a 5-hour dialysis and the ultrafiltration rate drops to 5000 5 100 = 10 mL/Kg/hr (and only just "safe"). The pore size in a UF membrane is mainly responsible for determining the type and size of contaminants removed. During the treatment, excess fluid is collected by filtering blood outside of the body then returning the blood to your body. However, adjustment of ultrafiltration rates to patients' vital signs and renal function has been associated with more effective decongestion and fewer heart failure events. PMID 24512880 4.
