How long a paralyzed patient can live is determined by the severity of the disease and the degree of post-care. If the patient is younger and the paralysis is a sequel of cerebral thrombosis, he should do turning the patient frequently and eat more vitamin and protein-rich food, and the general survival time is about 20 years. It should be noted that during the care process, try not to make the patient over-eat fatty food, and you can cooperate with the use of thrombosis, aspirin and other drugs to prevent the increase of blood viscosity and the recurrence of cerebrovascular disease. If the patient is older, the degree of disease is more serious, and there are more underlying diseases, the survival time is generally less, about 5-10 years. If the patient has a recurrence of cerebral infarction, the survival time is even shorter. If a patient with late stage diabetes is complicated by paralysis, the survival time will be even shorter because of the high blood sugar in the body, which will gradually cause edema and even ulceration of the lower limbs and complications of serious infections.
