Continuous Renal Replacement Therapies (CRRT) - Comparison - Continuous Veno-venous Hemofiltration (CVVH) utilizes convection. Replacement fluid is administered to maintain euvolemia and dilute the plasma concentration of solutes not present in the replacement fluid (i.e. urea nitrogen, creatinine). - Continuous Veno-Venous Hemodialysis (CVVHD) utilizes diffusion and convection. Replacement fluid is not used in CVVHD. - Continuous Veno-Venous Hemodiafiltration (CVVHDF) uses a combination of convection and diffusion. Replacement fluid is also used to maintain euvolemia as in CVVH. Samira Farouk, MD, MS, FASN @ssfarouk #Continuous #Renal #Replacement #Therapies #CRRT #Comparison #Nephrology
