Presentation Transcript

  1. General Care After Stroke, Including Stroke Units and Prevention and Treatment of Complications of Stroke

  2. Reasons for Admission • Serious illness • Potentially life-threatening disease • Risk for medical or neurological complications • Neurological deterioration • Observation, evaluation and treatment

  3. Organization of Stroke Care • Acute Stroke Units • Concentrate admissions to a specialized facility with skilled care and monitoring. • Shorten hospitalizations and reduce death and disability. • Reduce complications and promote rehabilitation.

  4. Organization of Stroke Care • Stroke Teams • Coordinated teams of health care professionals to coordinate efficient and effective care for stroke patients. • Stroke Teams play a part in the hyperacute, the acute and the rehabilitation phases of stroke care. • Involve the multidisciplinary team.

  5. Stroke Centers • Primary Stroke Centers • Use the cardiac/trauma model of delivering care. • Major elements: patient care and support services. • Define institutions where appropriate care can be given.

  6. Goals of Treatment After Admission • Continue care started in emergency department. • Observe for and prevent or control neurological and medical complications. • Start rehabilitation and discharge planning. • Evaluate for cause of stroke and start therapies to prevent recurrent stroke.

  7. Neurological Complications • Progression of thrombosis • Recurrent embolism • Brain edema • Hydrocephalus • Increased intracranial pressure • Hemorrhagic transformation • Seizures

  8. Medical Complications Myocardial infarction Pneumonia Congestive heart failure Airway obstruction Cardiac arrhythmias Hypertension Deep vein thrombosis Bladder infections Pulmonary embolus Depression Gastrointestinal bleeding Electrolyte disturbance

  9. After Admission • Initially treated with bed rest; mobilization begins as soon as the patient’s condition is stable • Pulse oximetry first 24-48 hours • Cardiac monitoring first 24 hours

  10. After Admission • Frequent assessments of vital signs and neurological status by nursing staff. • Protection of airway, especially if depressed consciousness or signs of brain stem dysfunction. • Supplemental oxygen if patient is hypoxic. • Assessment for cause of hypoxia.

  11. Heart Disease and Stroke • Heart disease often is the cause of stroke. • Most patients with stroke have heart disease. • Stroke, especially intracranial hemorrhage, can cause myocardial ischemia or cardiac arrhythmias. • Many persons will have cardiac arrhythmias or electrocardiographic abnormalities after stroke.

  12. Heart Disease and Stroke Sinus bradycardia Sinoatrial arrhythmia Ventricular tachycardia Atrial fibrillation Ventricular fibrillation PVC Idioventricular rhythms PSVT Torsades de pointes AV block

  13. ECG Changes and Stroke • ST-T segment elevation/depression • Pathological Q waves • Negative T waves • Abnormal U waves • QT prolongation

  14. Hypertension in Stroke • Arterial hypertension is common among persons with stroke: • risk factor for stroke • consequence of stroke • Usually declines spontaneously • Secondary to pain, vomiting, stress, anxiety • Secondary to increased intracranial pressure

  15. Treatment of Arterial Hypertension • Oral agents preferred • Continue or re-institute antihypertensive medications • Goal of lowering pressure by 15% during first 24 hours • If parenteral medications are used, prefer short-acting drugs

  16. Initial Management of Acute Stroke • Treat fever and search for the cause of fever; suspect pulmonary or urinary tract infections • Maintain hydration with intravenous fluids • Treat hyperglycemia and hypoglycemia • Assess swallowing before starting oral feedings • If necessary, consider enteral feedings

  17. Mobilization After Stroke • Early mobilization • positive for morale • expedites rehabilitation • lessens risk of pulmonary, skin, musculoskeletal complications • Watch for hypotension or neurological worsening • Protect against falls

  18. Prevention of DVT and Pulmonary Embolism • Mobilization • Heparin • LMW heparins/heparinoids • Oral anticoagulants • Aspirin • Alternating pressure stockings

  19. Brain Edema and Increased Intracranial Pressure • Peaks within one week of stroke • Earlier with hemorrhagic stroke • A leading cause of death • Seen with large multi-lobar strokes • Can be secondary to hydrocephalus or mass effect of a hematoma

  20. Brain Edema and Increased Intracranial Pressure • Common cause of neurological worsening • progression of stroke • secondary brain ischemia • herniation syndromes • Hallmark is depression of consciousness • Vital signs unstable and arterial hypertension

  21. Management of Brain Edema and Increased Intracranial Pressure • Restrict fluids moderately • Avoid hypo-osmolar fluids • Control fever, hypoxia, hypercarbia • Elevate head of bed by 30% • Monitor intracranial pressure

  22. Trial of Dexamethasone for Supratentorial Intracerebral Hemorrhage Dexamethasone Placebo n=46 n=47 Good Recovery 8 5 Poor Survivor 17 21 Dead 21 21 Infectious Complications 13 6 Pougvarin, et al. New England Journal of Medicine 1987;316:1229-1233..

  23. Intracranial Pressure • Hyperventilation to a pCO2 of approximately 28-30 mm Hg • Corticosteroids are not recommended • Mannitol, 0.25-1 g/kg intravenously given every 6 h maximum osmolarity 310 • Furosemide 40 mg intravenously

  24. Surgical Management of Brain Edema and ICP • Drainage of CSF fluid • Evacuation of hematoma • Resection of infarcted tissue • Hemicraniectomy

  25. Evaluation for Cause of Stroke • Magnetic resonance imaging of brain • Magnetic resonance angiography • Spiral CT imaging • Carotid duplex • Transcranial Doppler • Transthoracic echocardiography • Transesophageal echocardiography

  26. Prevention of Recurrent Stroke Cardioembolic Stroke • Oral anticoagulants • prosthetic valves: INR 2.5-3.5 • other causes: INR 2.0-3.0 • Stroke despite adequate anticoagulation • add aspirin • add dipyridamole • Contraindication for anticoagulation • Aspirin

  27. Prevention of Recurrent Stroke • Carotid endarterectomy if ipsilateral high-grade stenosis, acceptable risk, and skilled surgeon • Antiplatelet aggregating drugs • Aspirin • Ticlopidine • Aspirin and dipyridamole

  28. Rehabilitation • Critical part of care after stroke • Begin as soon as patient is stable and while the patient is still in an acute care bed • Tailor to individual patient’s needs • Progress in a step-wise progression • Maximize patient’s independence

  29. Decisions About Rehabilitation Influence Discharge Planning • In-patient rehabilitation unit • attached to acute hospital • free-standing hospital • Outpatient care • Home care • Skilled nursing facility

  30. Discharge Planning Considerations • Cognitive and functional status • Family and caregivers’ support • Financial resources • Patient and family education • Follow-up medical care, rehabilitation • Identify safe place of residence • Community support or resources
