The infusion treatment of facial palsy should be carried out according to the cause, for example, if the patient has peripheral facial palsy, the medication should be selected according to the condition during the acute phase. 1. If the patient has a heavy degree of facial palsy, intravenous infusion of hormone is needed to improve the swelling of facial nerve, such as dexamethasone. If there is a viral infection, the patient should use acyclovir antiviral, and at the same time give the patient oral mecobalamin, adenosylcobalamin, vitamin B12 and other drugs for nerve nutrition treatment. 2. If the patient’s facial palsy is caused by central facial palsy, such as cerebral infarction, the patient needs to use drugs to activate blood circulation and improve blood circulation in the brain for treatment, such as using sparing blood, vincristine, prostaglandin, edaravone for treatment. The drugs should also be selected according to the cause of the patient’s onset and the time of onset, such as the use of rt-PA thrombolysis, argatroban anticoagulation, edaravone cerebral protection, or the use of bactrim for fibre-lowering treatment, all of which need to be selected according to the patient’s condition.
