Emergency Medical Care for Neurologic Emergencies • • Provide reassurance. Ensure proper airway and breathing. Place the patient in a position of comfort. If you suspect stroke, transport immediately and notify hospital. • Assess and care for any injuries if you suspect any type of trauma.

Management of acute ischemic stroke l Systemic thrombolysis: Intravenous recombinant tissue plasminogen activator (rt-PA): Within 3 hrs of onset of stroke. Dose 0. 9 mg/kg, max 90 mg. l Antiplatelet agents: Aspirin 160 -300 mg within 2448 hrs (not during first 24 hrs following thrombolytic therapy). Clopidogrel a potential alternative. Combination of clopidogrel and aspirin currently being evaluated

Management of acute ischemic stroke (CONTD) l Anticoagulants: Heparin/LMWH are not recommended in acute treatment of ischemic stroke. Recommended in setting of atrial fibrillation, acute MI risk, prosthetic valves, coagulopathies and for prevention of DVT. l Intra-arterial thrombolytics: An option for treatment of selected patients with major stroke of < 6 hrs duration due to large vessel occlusion.

Management of acute ischemic stroke (CONTD) l l l BP management: Should be kept within higher normal limits since low BP could precipitate perfusion failure. Markedly elevated BP (>220/110 mm. Hg) managed with nitroglycerin, clonidine, labetalol, sodium nitroprusside. More aggressive approach is taken if thrombolytic therapy is instituted Blood glucose management: Should be kept within physiological levels using oral or IV glucose (in case of hypoglycemia)/insulin (in case of hyperglycemia) Elevated body temperature management: Antipyretics and use of cooling device can improve the prognosis

Management of Acute hemorrhagic stroke l Analgesics/Antianxiety agents: To relieve headache. Analgesics having sedative properties are beneficial for patients having sustained trauma (e. g. morphine sulphate) l Antihypertensives: (e. g. sodium nitroprusside, labetolol) l Hyperosmotic agents (e. g. mannitol, glycerol, furosemide): To reduce cerebral edema, and raised intracranial pressure. l Adequate hydration is necessary l Surgical intervention may occasionally be life saving

Management of TIA l Evaluation within hours after onset of symptoms l CT scan is necessary in all patients l Antiplatelet therapy with aspirin (50 -325 mg/d), consider use of clopidogrel, ticlopidine, or aspirin-dipyridamole in patients who are intolerant to aspirin or those who experience TIA despite aspirin use

Secondary prevention of stroke l Recurrence: Annual risk is 4. 5 to 6%. Five year recurrence rates range from 24 to 42%; one-third occur within first 30 days, hence high priority should be given to secondary prevention. l Patients with TIA or stroke have an increased risk of MI or vascular event. l Management of hypertension (goal <140/85 mm Hg) l Diabetes control (goal<126 mg/d. L) l Lipid management: Statins (goal cholesterol<200 mg/d. L, LDL<100 mg/d. L) l Antiplatelet agents: Aspirin (50 -325 mg), clopidogrel (75 mg). A fixed dose combination of the two drug may also be used l Anticoagulants: Warfarin (target INR 2 to 3); esp. recommended in patients with cardioembolic stroke l Appropriate life style modification (cessation of smoking, exercise, diet etc)
