When advanced liver cancer patients have symptoms such as inability to eat and difficulty in breathing, they can cooperate with doctors to improve their symptoms by intravenous infusion and puncture drainage. 1. Intravenous infusion: If patients with advanced liver cancer cannot eat, they can replenish corresponding nutrients through intravenous infusion, and at the same time need to replenish corresponding water, electrolytes and vitamins. 2. Puncture and drainage: patients with advanced liver cancer often have a large amount of fluid in the abdominal cavity, which will easily affect abdominal respiration and cause symptoms of respiratory difficulty. After abdominal puncture and drainage of ascites, dyspnea will be relieved. If patients with advanced liver cancer have difficulty in eating and breathing, they need to clarify the cause of the disease through relevant examinations in time, treat the cause and make a nutritional intake plan under doctor’s advice as much as possible.
