    Study Notes

    Cerebrovascular Disease

    • Most common neurological disorder among adults.
    • 3rd leading cause of morbidity and mortality in the U.S., following heart disease and cancer.
    • Involves pathological disorders of brain blood vessels, including thrombosis, embolism, and hemorrhage.

    Stroke Overview

    • Leading cause of permanent disability, impacting daily living and socialization.
    • Approximately 15% of stroke patients require institutionalization, 30% need assistance for daily activities, and 60% report decreased socialization.
    • Estimated annual financial burden of $15-20 billion due to stroke and related conditions.

    Stroke Etiology

    • Vascular obstruction primarily from thrombi or emboli (75% of cases), leading to ischemia and infarction.
    • Hemorrhagic stroke (25% of cases) can result from hypertensive vascular disease, ruptured aneurysms, or arteriovenous malformations.

    Stroke Epidemiology

    • Annually, around 750,000 strokes occur in the U.S.
    • Higher incidence in men compared to women.
    • Common risk factors include smoking, hypertension, obesity, cardiac disease, high cholesterol, diabetes, and the use of birth control pills.

    Prevention and Treatment

    • Lifestyle modifications recommended for stroke prevention.
    • Anticoagulants like warfarin or aspirin are advised for patients with atrial fibrillation.

    Infarct vs Ischemic Stroke

    • Infarct results from thrombus or embolus causing oxygen deprivation in cerebral tissue.
    • Ischemic stroke results from a decline in cerebral blood flow, leading to potential irreversible damage and an area called the ischemic penumbra that can still be salvaged.

    Clinical Manifestations

    • Sudden neurological impairment characterized by focal weakness, dysphagia, and aphasia.
    • Symptoms may resolve within 24 hours, indicating a transient ischemic attack (TIA).

    Diagnosis

    • Rapid diagnosis is crucial to identify candidates for thrombolytic therapy.
    • Time from symptom onset to treatment ("time to needle") should be within 3 hours.

    Diagnostic Tests

    • CT scan without contrast is the primary imaging technique.
    • Neurological exam utilizing the National Institutes of Health Stroke Scale (NIHSS) assesses severity through various factors such as level of consciousness and motor function.

    Clinical Management Goals

    • Key objectives include restoration of cerebral blood flow, prevention of recurrent strokes, neuroprotection, and supportive care.

    Pharmacological Management

    • t-PA (tissue plasminogen activator) should be administered within 3 hours of symptom onset in eligible patients.
    • Other medications include anti-platelets, anti-coagulants, and gradual antihypertensive treatments to avoid rapid blood pressure drops.

    Nursing Responsibilities

    • Monitor for neurological changes and administer t-PA as ordered.
    • Oversee oxygen and glucose levels while preventing complications like UTIs, bedsores, and thrombophlebitis.
    • Collaborate with various professionals for comprehensive care.

    Intracranial Pressure (ICP) Monitoring

    • Essential for managing pressures within the skull; prevents cerebral ischemia and potential brain herniation.
    • Intraventricular catheter (IVC) is the most common ICP monitoring method.

    ICP Measurement Standards

    • Normal ICP ranges from 0-10 mmHg, with upper limits at 15 mmHg.
    • Readings can temporarily spike to 100 mmHg during coughing or straining.
    • Symptoms arise when levels exceed 20-25 mmHg, necessitating vigilant monitoring for catheter obstruction.

    Indications for ICP Monitoring

    • Head injuries assessed via Glasgow Coma Scale (GCS) can prompt the need for ICP evaluation.

    Cerebrovascular Disease

    • Most common neurological disorder among adults.
    • 3rd leading cause of morbidity and mortality in the U.S., following heart disease and cancer.
    • Involves pathological disorders of brain blood vessels, including thrombosis, embolism, and hemorrhage.
