What is the effectiveness of the treatment for subacute liver failure? We all know that the common causes of liver failure are mostly seen in advanced hepatitis cirrhosis, drug toxic liver failure, advanced alcoholic cirrhosis, autoimmune diseases of the liver, etc. Generally speaking, subacute liver failure refers to the onset of 15 days to 26 weeks, often with an acute onset, often showing jaundice, impaired coagulation mechanism, abdominal and abdominal fluid, elevated transaminases and bilirubin indicators, etc. Treatment should emphasize early diagnosis, early treatment, and targeted treatment for different etiologies of patients. At present, the diagnosis of subacute liver failure lacks precise and effective clinical treatment methods, and often patients do not seek medical attention in time, which can lead to serious consequences and crisis patients’ lives. The most common clinical treatment, firstly, is nutritional support therapy to enhance the patient’s resistance and reduce liver cell damage. Secondly, drug therapy is beneficial for faster recovery of damaged liver cells. Again, oral probiotics such as lactulose are administered to keep the stool open, maintain the intestinal barrier and reduce the occurrence of primary peritonitis. Finally, artificial liver therapy can reduce the absorption of toxins in the body and reduce the burden on the liver. Liver transplantation can be considered for end-stage liver failure, but due to the tight liver supply and long-term immunosuppressive drugs after surgery, the long-term survival rate of patients is low.
