1. Monitor the abnormalities of consciousness, respiration, blood pressure and pulse rate, and provide symptomatic treatment to ensure the stability of vital signs. 2.Ensure unobstructed airway, and possibly perform tracheotomy if necessary 3.Sedation and anticonvulsion 4.Supplementation of water-electrolyte and nutrition and prevention of complications 5.Treatment of cerebral edema and improvement of cerebral perfusion 6.Early bedside rehabilitation treatment? In the acute phase of cerebral infarction, the principle of not lowering blood pressure even if it is elevated is a must. The rise of blood pressure in the acute phase of cerebral infarction can maintain cerebral blood flow and inhibit the expansion of the infarcted area. The acute treatment of atherosclerotic cerebral infarction focuses on: 1. prevention of deterioration 2. reduction of cerebral edema 3. treatment of complications and underlying diseases. Currently, the effective treatment for cerebral infarction is considered to be: 1. oral aspirin 2. thrombolytic therapy within 3 hours after onset 3. rehabilitation therapy 3. emergency treatment of cerebral hemorrhage The basic medical treatment for cerebral hemorrhage is anti-cerebral edema treatment, while surgical removal of hematoma needs to be chosen according to the specific conditions of the patient. The focus of treatment in the acute phase is: 1. anti-cerebral edema treatment 2. prevention of hematoma enlargement 3. selection of patients suitable for surgical treatment 3. treatment of systemic complications and underlying diseases 4. emergency treatment of subarachnoid hemorrhage The fundamental treatment of subarachnoid hemorrhage is neurosurgery and neurointerventional treatment. The focus of treatment in the acute phase is: 1. prevention of rebleeding 2. anti-cerebral vasospasm treatment 3. anti-brain edema treatment 4. treatment of intracranial complications 5. prevention and treatment of systemic complications
