Cerebral insufficiency of blood supply is a common clinical manifestation, including cerebral insufficiency of blood supply and cerebellar insufficiency of blood supply. Most of the conditions are not serious and can be seen in a variety of causes, such as severe hypotension and hypovolemia when it can be caused. If there is cerebral atherosclerosis, hyperlipidemia, diabetes mellitus, hypertension, it is also easy to occur. The main thing is to actively control the cause of the disease, including controlling the patient’s blood lipids, blood sugar and blood pressure to prevent the patient from developing atherosclerosis, which can be done by taking oral aspirin to anti-platelet aggregation and oral statins to regulate lipids and stabilize plaque, commonly used are simvastatin, resulvastatin and atorvastatin. If the patient’s blood pressure is too low, he or she can take oral raw vein drink. In case of severe hypovolemia, the etiology should be actively analyzed and the corresponding etiological treatment should be carried out, and if necessary, volume-expanding drugs such as intravenous infusion of 706 plasma substitute can also be used, which can also cause cerebral infarction when the cerebral blood supply is severely insufficient.
