Patients with hepatic coma usually live for about 1 month, and the survival time is mainly affected by the specifics of hepatocellular failure. 1. If the patient’s liver function status is good. For example, patients with good liver function, patients with early stage of acute drug liver injury, etc., can find the cause of liver failure in patients, and carry out targeted treatment during coma period and get effective control, then the patients’ condition may be recovered better, and may be able to greatly prolong their survival period. 2. If the patient’s liver function is poor. For example, hemorrhage, massive ascites, fulminant hepatic failure. This kind of patients have been unable to effectively control the original disease, the condition is more serious, the survival period is seriously shortened, if not timely and effective control of the disease, or even direct death.
