Children with fulminant hepatic failure are in critical condition and high mortality. Blood purification technology as the most frequently used devices of non-biological artificial liver plays an effective role in helping children through the liver failure risk, liver cell regeneration and survive to liver transplantation. Artificial liver has been used for more than 50 years. New blood purification models which based on plasma exchange, hemoperfusion, hemodiafiltration andother methods have been widely used in clinical practice and become one of the important therapies for fulminant hepatic failure. Artificial liver has been used in children, but multi-center studies are needed.
