If a patient with cerebral infarction is in a coma, it is considered a more serious condition. If there is no combination of other complications, and the patient with cerebral infarction is merely comatose, he or she can survive for a long time after treatment. If the patient cannot eat and life cannot be sustained, the diet can be strengthened by nasal feeding, or the nutrition can be increased by intravenous infusion. If there are no complications, they can survive for a long time, for example, they can live for 10-20 years. However, in the acute stage, we must pay attention to the appropriate application of oral or intravenous drugs, for example, we can inject drugs to improve the blood supply to the brain in the gastric tube, and we can also treat for cerebral edema, for example, mannitol is an effective dehydration agent, which can have a better effect.
