Document Summary
Elevate head of bed 30 degrees if no symptoms of shock or injury occur. Drugs to lower bp are used only if bp is markedly increased. (metoprolol, cardene) Fluid and electrolyte balance must be controlled carefully. Adequate hydration promotes perfusion and decreases further brain injury. Adequate fluid intake during acute care via oral, intravenous (iv), or tube feedings should be 1500 to 2000 ml/day. Overhydration may compromise perfusion by increasing cerebral edema. Used to reestablish blood flow through a blocked artery to prevent cell death in patients with acute onset of ischemic stroke symptoms. Must be administered within 3 to 4. 5 hours of onset of clinical signs of ischemic stroke. Pt screened before tpa can be given: Non contrast ct or mri scan to rule out hemorrhagic stroke. Screening for recent history of gastrointestinal bleeding, stroke, or head trauma within the past 3 months, or. Aspirin is used within 24 to 48 hours of stroke.
