Abstract: 【Abstract】Continuous renal replacement therapy (CRRT) has the roles of ultrafiltration to remove excess water, convection to clear medium and small molecular solutes, and adsorption to eliminate inflammatory mediators. The therapeutic models of CRRT are developed progressively, such as continuous venous-venous hemofiltration (CVVH), continuous venous- venous hemodiafiltration (CVVHDF), high- volume hemofiltration (HVHF), continuous plasma filtration adsorption (CPFA), and slow continuous ultrafiltration (SCUF). CVVH is the most commonly used model, usually as an adjuvant method for refractory heart failure, severe acute pancreatitis, rhabdomyolysis, and many others; CVVHDF has been widely used for the treatment of sepsis;
HVHF is a treatment often for severe sepsis and septic shock; CPFA can be used in severe inflammatory response syndrome and sepsis; SCUF is often used in patients with refractory heart failure, edema, and overload of extracellular fluid volume. Every CRRT technology has its own characteristics, and the selection of therapeutic model and dosage must be individualized based on clinical situation of the patient.
