Pain in decompensated cirrhosis may be caused by the presence of abdominal fluid, infection, bleeding after varicose veins, etc., which should be treated with hemostasis, anti-infection, fluid extraction, etc. 1. Abdominal fluid accumulation: diuretics (such as spironolactone combined with furosemide, etc.), aspiration by laparotomy, transjugular intrahepatic portal vein shunt, etc. can be used. 2. Infection: the body’s immunity decreases, the intestinal mucosal barrier function decreases, abnormal glucose metabolism, etc., prone to infections, such as bacterial peritonitis, biliary tract infections, etc., which can cause pain, and antibiotics can be used, such as cefoperazone, sulphadiazine and levofloxacin. 3. Bleeding: esophagogastric fundal varices are the most common, causing severe abdominal pain, hemostasis should be carried out, drugs can be used (e.g. otitrexate, growth inhibitor, etc.), endoscopic ligation, balloon compression, etc. to stop bleeding. Cirrhosis in the decompensated stage usually has a rapid change in condition and needs to be treated as soon as possible.
