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.
