The causes of syncope caused by cervical spondylosis include vertebral artery compression and sympathetic nerve stimulation, etc. According to the causes, vasodilators, closure therapy and other treatments can be used. 1. Vasodilator: patients with cervical spondylosis can compress or stimulate vertebral artery due to cervical spine degeneration, causing insufficient blood supply to the brain and thus fainting. Therefore, vasodilators such as Flunarizine can be used to relieve the symptoms. Flunarizine can appear depression, motor ankylosis and other adverse reactions, allergic to this drug, pregnant and lactating women are prohibited. 2. Closed treatment: cervical degeneration stimulates the sympathetic nerves around the carotid artery, causing nerve excitation, which can also lead to vasospasm. Generalized lidocaine, vitamin B12 and other drugs for closed treatment, can lift the vasospasm, improve the blood supply to the brain. Lidocaine has adverse reactions such as dizziness and convulsions, and is contraindicated in those who are allergic to the drug. Vitamin B12 has adverse reactions such as hypokalemia and hyperuricemia. 3. Other treatments: The stimulation of cervical vertebrae on cervical blood vessels and nerves can be reduced by reducing neck activities and neck traction, thus preventing syncope. When the symptoms are serious, surgery can be performed. All of the above medications should be taken as prescribed by the doctor. If cervical spondylosis is diagnosed, early standardized treatment is recommended to reduce the adverse effects of the disease.
