Continuous Renal Replacement Therapy

Background

Continuous renal replacement therapy (CRRT) is commonly used in the intensive care unit (ICU) setting and can consist of continuous venovenous hemodialysis (CVVHD), continuous venovenous hemofiltration (CVVH), or continuous venovenous hemodiafiltration (CVVHDF). Each of these procedures involves the slow passage of blood, continuously (24 hours a day), through a filter to remove various waste products and/or fluid.
