Nimodipine can be used to treat or prevent cerebral vasospasm after brain tumor surgery. Generally speaking, oral or intravenous nimodipine can prevent or treat cerebral vasospasm after brain tumor surgery. It is recommended that Nimodipine should be used in the early stage of onset of the disease or after surgery under doctor’s instruction in a timely manner, and meanwhile, the acid-base balance of the patient’s body fluids as well as the blood volume should be paid close attention to, so as to avoid acid-base imbalance or hypovolemia and other situations. There is no specific treatment for cerebral vasospasm after brain tumor surgery, generally only symptomatic treatment. In addition, actively preventing cerebral vasospasm and making good preoperative and intraoperative preparations can effectively reduce the probability of postoperative cerebral hemospasm, such as maintaining the patient’s normal blood pressure, washing the blood in the ventricles during the operation, and opening the pathway of cerebrospinal fluid circulation.
