A car accident that causes brainstem injury requires a risk period of 2-3 weeks. Because within 2-3 weeks, the brainstem will mainly face the barrier of brain edema, and if the brain edema is more serious, the patient’s vital signs may be affected. Comparing a person to a house, the brainstem is equivalent to the foundation of the house, so damage to the brainstem occurs and is usually more serious. Treatment requires ventilator-assisted ventilation, as well as drugs to nourish the nerves and to prevent and treat related complications. For these patients, early rehabilitation is recommended, if the situation permits, to promote maximum recovery from neurological impairment. The main means of rehabilitation treatment include hyperbaric oxygen, Chinese acupuncture, physical therapy, and electrical nerve stimulation.
