Insufficient blood supply caused by cervical spondylosis is called vertebral artery cervical spondylosis, which is due to the hyperplasia of the cervical vertebral joint or foraminal stenosis of the vertebral artery, resulting in extrusion and stimulation of the vertebral artery, leading to a decrease in blood supply to the brain from the vertebral artery, resulting in vertigo, nausea, vomiting and other related manifestations, the following measures can be taken: 1. Strict bed rest must be taken, avoiding cold in the neck and violent head turning and head lowering for too long. The pillow must be of appropriate height to maintain the normal physiological curvature of the cervical spine to avoid further aggravation. 2. Intravenous injection of guipizidine maleate, betahistine hydrochloride, tensin injection, and hemosiderin injection can be given to increase the blood supply to the brain from the vertebral artery and improve the symptoms of vertigo. 3. Intramuscular injection of metoclopramide hydrochloride can be given to improve gastrointestinal reactions and reduce the symptoms of nausea and vomiting. 4. 4.Warm water bags can be used to increase the local temperature and blood vessels can be dilated to help increase the blood supply to the brain from the vertebral artery and relieve the symptoms.
