In case of axonal injury, the treatment effect is generally poor, and some drugs to improve blood circulation or neurotrophic drugs can be applied for treatment. Drugs to improve blood circulation are applied to salvia, safflower, panax ginseng and also intravenous infusion of shuxin, sparing blood, Chuanxiongzin and vincristine, etc. Neurotrophic drugs commonly used clinically are methylcobalamin, adenosylcobalamin, vitamin B1 and vitamin B6, most of which are caused by chronic ischemia and hypoxia. Chronic ischemia and hypoxia may cause nerve demyelination, and in severe cases, axonal lesions may be caused, as well as peripheral neuropathy.
