Liver failure is categorized into acute liver failure, subacute liver failure and chronic liver failure. 1. Acute Liver Failure: Acute Liver Failure refers to the development of coma, severe jaundice, impaired coagulation mechanism, hemorrhage, and ascites in a short period of time, i.e., within one or two weeks. 2. Subacute liver failure: Subacute liver failure takes a little longer. In our country, it is more often referred to as slow plus acute liver failure, which refers to the original chronic hepatitis or cirrhosis, but the liver function is still maintained at the normal level, and then suddenly there is a sharp deterioration of liver function in a short period of time. 3. Chronic liver failure: chronic liver failure refers to the end stage of liver cirrhosis, jaundice, coagulation mechanism disorder, bleeding, ascites, etc. is not a sudden aggravation, but a slow aggravation process. In addition, patients with hepatic and renal insufficiency are recommended to go to the hospital in time to avoid delay.
