Acute Stroke Care 2008A Clinical Update 2008 Mary Becker, MD
Acute Stroke Initial Assessment in the ED • Physical Exam • Assess patient’s ability to swallow (or make patient NPO) • NIH Stroke Scale
Acute Stroke Initial Assessment in the ED • Diagnostic Studies • Non contrast CT of the head • Lab work: CBC with diff., BS, PT/INR, PTT (if on coumadin), lytes, BUN/Cr, cardiac enzymes • EKG • For select patients consider: toxicology screen, pregnancy test
Acute Stroke Initial Assessment in the ED • Diagnosis • Consider Stroke Mimics: • Metabolic- hyper/hypoglycemia • Trauma • CNS lesions/tumors • Complicated migraines • Post ictal state (Todd’s paralysis) • Pyschogenic
Acute Stroke in the ED Consults • Consider a neurology consult on any patient who may be a tPA candidate or any patient with an unclear presentation • Call One Call: 1 866-662-6632
Acute Stroke in the ED • Treatment • For tPA refer to the MaineGeneral tPA Guideline • ASA (unless contraindicated)
Acute Stroke in the ED • BLOOD PRESSURE Treatment • For patients NOT receiving lytic therapy: Treat SBP> 220 or DBP> 120 or MAP > 120 • Recommended drugs: LABETALOL 10 MG IV, may repeat dose every 10 minutes to a max of 150 mg if needed • OR • NICARDIPINE (1mg/ml) start at 5mg/hr and titrate (max dose of 15mg/hr) • AVOID LARGE OR RAPID DECREASES IN BP( no more than a 15-25% decrease over 24 hrs)
Acute Stroke in the ED • For patients receiving lytic therapy treat for SBP>185 or DBP >110 • Recommended drugs: • LABETOLOL 10-20 mg iv over 1-2 min, may repeat x1 • Or • NITRO PASTE 1-2 inches • Or • NICARDIPINE drip 5mg/hr, titrate up by 0.25 mg/h at 5-15 min intervals, max dose 15 mg/h; when desired BP achieved reduce to 3mg/h
Acute Stroke in the ED • Treatment, cont. • O2 as needed • Treat hypo/hyperglycemia (>160) as needed
Acute Stroke Day 1 • Additional Diagnostic Studies • If necessary: TEE, MRI/MRA, carotid dopplers, CXR (if not done in ED) • If ECG abnormal, consider cardiac enzymes • Telemetry for first 24 hours of stay • Lipid panel
Acute Stroke Day 1 • For all patients: lipid panel • If no evidence of Htn, increased lipids or older age consider hypercoaguable work-up: • Leiden factor V, Protein C and S, homocysteine, ANA, anticardiolipin antibodies, lupus anticoagulant, ESR, RPR, TSH, RF,
Acute Stroke Day 1 • Treatment • Evaluate for continuation of patient’s prior medications, (especially antihypertensives & antihyperglycemics) • If necessary: IV hydration, treatment of pain • If necessary: lipid lowering therapy • VTE PROPHYLAXIS: (heparin 5000units sc BID (do not combine with iv heparin therapy) • Lovenox 40mg sc qd • if patient’s creatinine clearance less than 30 or patient body weight less than 45 kg use: Lovenox 30mg sc qd
Acute Stroke Day 1 • Treatment, con’t. • Antiplatelet drugs • ASA is gold standard and lowers stroke risk by aprx 15% • Plavix and/or aggrenox may be considered in select cases
Acute Stroke Day 1 • Treatment: Heparin • Possible uses: • Suspected hypercoaguable state • Low blood flow from significant large vessel stenosis • Arterial dissection • Cardiac embolic source with high risk of occurrence
Acute Stroke Day 1 • Treatment: Coumadin • Proven treatment for cardiac embolic source of stroke in a fib patients • Commonly used for c embolic source in patients with LV thrombus, recent MI or cardiomyopathy • Unproven efficacy if no embolic source found
Acute Stroke Day 1 • Contraindications for Heparin/Coumadin • Recent GI bleed • Recent ICH • Vitamin K deficiency • Abnormal platelet level • Frequent falls
Acute Stroke Day 1 • Contraindications for Antiplatelet drugs • Active bleeding • GI lesions (ulcers) • Recent ICH • Allergy • Use caution with liver or kidney impairment
Acute Stroke: • Begin patient and family education early • Begin developing a plan for rehab early • Consider rehab for every patient • Physiatrists are available by phone through New England Rehab Hospital to assist in determining patient appropriateness for rehab.
