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.
