The patient suffered from cerebral infarction. The hospital looked at other people's normal brain CT films, but it was not diagnosed. It took 2 days to find out that the patient was given the correct treatment. If the patient does not leave any sequelae, the hospital will certainly not constitute a medical accident, because there is no consequence, at most it is a small mistake, and generally no compensation is needed. If the patient has left sequelae such as hemiplegia, it is necessary to identify whether this sequela has anything to do with delaying treatment for 2 days and how much it has to do. Generally, this kind of situation is at most a secondary responsibility or a secondary responsibility, and it is rarely recognized that the hospital is the main responsibility.
