There are many causes of cerebral ischemia and hypoxia, the common ones being heart disease, narrowing of blood vessels in the brain, insufficient blood supply to the carotid arteries, and cerebral atherosclerosis. The key to treatment is to find the cause of the disease and then treat it according to the cause. Early treatment is beneficial to prevent the aggravation of cerebral ischemia and prevent further development of diseases such as cerebral infarction and vascular dementia. Mitigation measures need to be decided according to specific causes: I. General treatment: 1. Adjustment of living habits: maintain emotional comfort and adequate sleep, avoid overwork, eat more vitamin-containing foods, such as fresh vegetables and fruits; 2. Treatment of the original disease: if cerebral ischemia and hypoxia are caused by diseases such as vertebral artery cervical spondylosis and heart disease, the original disease needs to be treated in time to avoid missing the best treatment period and symptoms aggravate. Second, drug treatment: 1, anticoagulants: commonly used drugs include aspirin, clopidogrel, warfarin, etc. The application of anticoagulant drugs is beneficial to prevent thrombosis and properly relieve the symptoms of dizziness and headache caused by cerebral ischemia and hypoxia; 2, vasodilator drugs: such drugs are beneficial to expand cerebral blood vessels, improve blood circulation in the brain and relieve cerebral ischemia and hypoxia, commonly used drugs such as nimodipine and vincristine, of which Nimodipine has a relieving effect on cerebral vascular spasm, and can also protect nerve cells, which can reduce ischemic brain damage. Surgical treatment: If the patient is suffering from cerebral ischemia and hypoxia due to insufficient blood supply caused by vascular stenosis, it may be necessary to perform suitable carotid endarterectomy or carotid angioplasty and stent implantation when the degree of stenosis is severe. Chinese medicine: Qingkailing injection, Waking Brain Jing injection, suitable for patients with phlegm-heat signs and cerebral orifice paralysis. Panaxia tianma pill is suitable for wind-phlegm obstruction. Acupuncture: Baihui, Fengchi, Hegu, Waiguan, Quchi, Hand Sanli, Diaphragm Yu, Kidney Yu, Fenglong, Taichong, Qihai, Foot Sanli and Sanyinjiao are often used to relieve the symptoms of cerebral ischemia and hypoxia. In addition, during the treatment period, if the patient has severe symptoms of cerebral hypoxia, a breathing machine should be used to continuously supply oxygen to the patient’s brain to avoid the threat to the patient’s life safety due to prolonged cerebral hypoxia.
