Overview
Acute liver failure is classified into hyperacute , acute and subacute depending upon the time lapsed between appearance of jaundice to encephalopathy. It is also classified into fulminant an subfulminant basing upon the time lapsed from start if illness to onset of encephalopathy.
Classification
1) The 1993 classification defines [1] It reflects the fact that the pace of disease evolution strongly influence prognosis. Underlying aetiology is the other significant determinant of outcome.[2]
- Hyperacute as within 1 week,
- Acute as 8-28 days and
- Subacute as 4-12 weeks
2) Acute liver failure may be fulminant or subfulminant. Both the forms have poor prognosis
- Fulminant hepatic failure - Development of hepatic encephalopathy within 2 months after the onset of acute liver disease.
- Subfulminant hepatic failure - Development of hepatic encephalopathy within 2 months to 6 months after the onset of acute liver disease
