When treating liver failure, the following points need to be noted: 1. Avoid intake of drugs and foods that are damaging to the liver; 2. Liver protection, enzyme-lowering therapy, and drug therapy to improve and repair liver cells are needed; 3. Three main problems occur when liver failure occurs, one is an increase in bilirubin, which is the phenomenon of bilirubin separation; second, blood glucose continues to drop, and even lower blood glucose is more difficult to correct, because when liver function is impaired Third, coagulation dysfunction occurs because the liver is an important coagulation factor synthesis organ, such as vitamin K1-like coagulation factors, fibrinogen, and prothrombin are all synthesized through the liver, and when liver failure occurs, coagulation factor synthesis Impaired clotting factor synthesis can cause bleeding, resulting in the occurrence of diffuse intravascular coagulation. If bilirubin is high, the artificial liver system can be used to remove bilirubin from the blood; continuous hypoglycemia should be supplemented in time to prevent further damage to brain function caused by hypoglycemia; if coagulation dysfunction occurs due to liver failure, exogenous supplementation of coagulation factors, such as fresh frozen plasma, fibrinogen, and prothrombin complex, is needed to reduce bleeding. The first treatment of renal failure should pay attention to avoiding, reducing or not using drugs that are damaging to the kidney. When acute renal failure occurs, renal failure mainly causes water-electrolyte acid-base disorder, water retention and acidosis, so bedside blood purification therapy is needed in renal failure. Bedside blood purification therapy can improve excessive water retention in the body, can reduce the situation of potassium ion increase, and correct Acidosis.
