Analyzing the dangerous factors of the prognosis of fulminant hepatic failure (FHF).

To explore the dangerous factors of the bad prognosis of fulminant hepatic failure. We analyzed the relation between prognosis and age, etiologic feature, complication, index of laboratory examination. When the patients who were more young, the survival rate were more higher.The serum levels of AST/ALT,TBil/DBil,TBA were significantly higher in the blood samples from the death group than from the survivor group. The level of Tch was contrary. The survival rate was significantly higher in patients whose PTA 40% , and similar result was obtained in patients whose APTT 45 seconds. The age, the complication and the index of the laboratory examination are the important factors in judging the prognosis of fulminant hepatic failure.
