For patients with advanced liver cancer, the time left for life is not too long, basically 3-6 months. If hepatic coma is combined with hepatic encephalopathy, which is the most serious stage of hepatic encephalopathy, the infection and upper gastrointestinal bleeding must be controlled in time to avoid rapid and massive potassium drainage and diuresis, or ascites release. It is important to correct the water, electrolytes, and acid-base imbalance. If these are slowly relieved, the patient will slowly come to consciousness again. If these conditions are not corrected in a timely manner, the patient’s life may soon become life-threatening.
