After hepatocellular carcinoma intervention, the puncture site is released from compression, at this time, the perioperative observation is basically over and the patient can get out of bed for normal activities, but cannot be discharged. Because there are some complications after interventional surgery, such as nausea, vomiting, fever, right upper abdominal pain, etc., which need further treatment, it is recommended to observe for one week and discharge if there are no special symptoms. Whether there is any damage to liver cells, kidney function, brain infarction or heart discomfort needs further observation. After hepatocellular carcinoma intervention, it is necessary to focus on observing the liver function, such as whether there is any increase in jaundice, transaminases, and whether there is any obvious damage to kidney function. Most of the contrast agent is excreted through the kidney, while a small part is excreted through the liver and biliary tract. It should be observed whether there is any significant effect on coagulation function, whether there is significant bone marrow suppression by chemotherapy drugs, and whether there is any significant decrease in white blood cells, all of which need to be further observed and can be discharged if there are no significant complications.
