Dizziness with low cranial pressure can be improved by rehydration therapy, caffeine, corticosteroid alcohol and other drugs symptomatic treatment, and low cranial pressure caused by secondary causes needs to be treated for the causes. 1. Rehydration therapy: low cranial pressure dizziness is due to the reduction of cerebrospinal fluid, you can carry out a large amount of rehydration fluid to raise the cranial pressure and reduce the symptoms of low cranial pressure. The amount of rehydration fluid reaches at least 3,000 milliliters per day, mainly saline. 2. Sodium benzoate caffeine: caffeine can block adenosine receptors, make intracranial vasoconstriction, increase cerebrospinal fluid pressure and relieve headache. If necessary, caffeine can be injected subcutaneously or intramuscularly to relieve the symptoms of low cranial pressure syndrome. However, continuous use of this drug can produce dependence, need to be used with caution. 3. Corticosteroids: Corticosteroids, such as prednisolone tablets, may help negative feedback regulation of the nervous and immune systems and improve the symptoms of low cranial pressure, but their use is controversial. 4. Etiologic treatment: Depending on the secondary cause, autologous epidural blood patches, percutaneous fibroglue placement, dural tear repair, duroplasty, and other treatments are possible. Patients with low cranial pressure and dizziness need to go to the hospital for treatment, and do not blindly self-medication.
