Infusion for cerebral insufficiency is useful, but not all patients with cerebral insufficiency require infusion therapy. Usually, in neurology and neurosurgery, infusion is only considered for severe cerebral artery insufficiency, or for acute attacks of cerebral artery insufficiency, when patients have severe clinical symptoms and most of them have obvious gastrointestinal symptoms such as nausea and vomiting that prevent them from taking medications. For such patients, aggressive intravenous infusion therapy is usually taken. The main drugs for infusion include low molecular dextrose, salvia powder injection, vincristine injection, nimatoprost injection, and even other drugs to improve cerebral circulation.
