In general patients, blood pressure should be in the normal range, high pressure is systolic pressure in the 90-140mmHg, low pressure is diastolic pressure 60-90mmHg can be. Of course, if the patient was hypertensive before, this is also considered normal as long as the original blood pressure is kept within the normal range. If the patient’s blood pressure is high, the first thing to consider is whether the patient has cerebral edema or rebleeding in the surgical area, which causes the cranial pressure to increase and occupy, so we should review the head CT in time. Then, we should check the blood count, whether the hemoglobin is within the normal range, and whether the red blood cell pressure is within the normal range. Blood pressure after meningioma surgery is mainly controlled within the normal range. If it is not feasible to have high or low blood pressure, it is necessary to find out the cause of it in time for symptomatic treatment.
