If a patient has high blood pressure and is unconscious, he or she should quickly call 120 and should remain calm and let the 120 doctor come to the home with professional equipment to give resuscitation. After arriving at the hospital, quickly improve the head CT and MRI to rule out whether hypertension, resulting in hypertensive crisis and hypertensive encephalopathy, leads to cerebral hemorrhage and acute cerebral infarction. In the case of cerebral hemorrhage, the patient should be given mannitol and other drugs to rapidly dehydrate and lower the intracranial pressure while preparing for surgery. In the case of acute cerebral infarction, when applying dehydrating drugs to lower intracranial pressure, apply certain drugs to improve cerebral blood supply and antihypertensive drugs, and send the patient to the monitoring room for systematic monitoring of heart rate, blood pressure, pulse rate, oxygen saturation, etc., and regularly lower the blood pressure.
