Subarachnoid hemorrhage requires general treatment such as monitoring vital signs and avoiding emotional stress, as well as medication and surgery depending on the condition. 1. General treatment includes close monitoring of the patient’s vital signs, maintaining the normal function of the circulatory and respiratory systems, avoiding emotional stress, and restricting the amount of fluid intake. 2. Drug treatment includes preventing rebleeding (aminoglycolic acid and other hemostatic drugs), preventing hydrocephalus (mannitol and other drugs for lowering cranial pressure), sedative drugs (diazepam and other drugs), and preventing cerebral vasospasm (nimodipine and other drugs). Drugs should be used under the guidance of a doctor. 3. Surgery, if the hematoma is large, surgery is needed to remove the hematoma. If the diagnosis of subarachnoid hemorrhage is confirmed, targeted treatment should be carried out as soon as possible, such as interventional surgery to embolize or clip the aneurysm or brain tumor resection, etc., and if hydrocephalus occurs, it can be used for puncture drainage. Early medical intervention can improve the prognosis of patients with subarachnoid hemorrhage to a certain extent.
