Once paralysis occurs in patients with paralysis, the quality of life is severely diminished and many complications can occur. This affects the prognosis of the patient and the life expectancy of the patient. Patients with paralysis have poor circulation, so they are at increased risk for cerebral thrombosis and also for venous thrombosis of the lower extremities. In addition, paralyzed patients are also prone to complications such as pulmonary infections, decubitus ulcers, and venous thrombosis of both lower extremities, while venous thrombosis of both lower extremities can easily cause pulmonary embolism, which can endanger the patient’s life at any time. Once a patient becomes paralyzed, various complications will follow and often the patient’s life will be affected. The prognosis of paralyzed patients and how long they survive is closely related to the care of their families.
