Management of Patients with Neurological disorders Prepared By: Hanaa Farahat Ibrahim Clinical Instructor in MubarakKhol Institute of Nursing Under supervision of: Prof. Dr. Magda Abd El Aziz Prof. of Medical Surgical Nursing Department Faculty of Nursing Ain-Shams University 2010 Cerebrovascular accident disorders (Strokes) “Stroke is the clinical term for acute loss of perfusion to vascular supply of the brain, resulting in ischemia and a corresponding loss of neurologic function. Classified as either hemorrhagic or ischemic, strokes typically manifest with the sudden onset of focal neurologic deficits, such as weakness, sensory deficit, or difficulties with language. Incidence of Stroke: The World Health Organization estimates that 15 million people suffer a stroke worldwide each year, resulting in 5 million deaths and 5 million people permanently disabled. While in the United States approximately 795,000 strokes occur each year (American Heart Association 2006). Risk factors of Stroke Nonmodifiable Modifiable • • • • •Life style habits Age Sex Race Heredity ( Alcohol intake – cigarette smoking – obesity – high fatty diet- drug abuse). •Pathological conditions (Cardiac diseases- diabeteshypertension) Etiology & Pathophysiology To ensure optimal cerebral functions and prevent neurologic deficits the blood flow must be maintained at 750 to 1000 ml/min. (55 ml/100 g brain tissue) or 20% of the cardiac output. If the blood flow to the brain is totally interrupted, neurologic metabolism is altered in 30 seconds, metabolism stops in 2 minutes, and cellular death occurs in 5 minutes. Etiology & Pathophysiology CONT.. • Factors that affect the blood flow is divided to : • Extracranial factors • Intracranial factors • Atherosclerosis Factors that affect the blood flow Extracranial factors Viscosity Intracranial factors Cardiac output Metabolic factors •High CO2 •Low O2 tension •High Hydrogen ion Atherosclerosis Systemic blood pressure Mean BP fall below 70 mm Hg or raise above 160 mm Hg Blood vessels Increase intracranial pressure •Congenital anomalies •Stroke , Neoplasm Collateral circulation •Inflammation, Trauma •Hydrocephalus Types of stroke Ischemic stroke Hemorrhagic stroke Ischemic stroke • Ischemic stroke or brain attack is a sudden loss of function resulting from disruption of the blood supply to a part of the brain. • Ischemic stroke are subdivided into five different types based on the cause : • Large artery thrombosis • Small penetrating artery thrombosis • Carcinogenic embolic stroke • Cryptogenic strokes, which have unknown cause. • Strokes from other causes, such as coagulopthies, migraine, and spontaneous dissection of the carotid artery. Patophysiology of ischemic stroke Ischemia Energy failure Sign POD Iron imbalance Acidosis Intracellular calcium increased Glutamate Depolarization Cell membranes and protein break down formation of free radical protein production Cell damage Smeltzer & Bare 2009 Clinical manifestations of ischemic stroke • Numbness or weakness of the face, or leg, especially on one side of the body • Confusion or change on mental status • Trouble speaking or understanding speech • Visual disturbance • Difficulty walking, dizziness, or loss of balance or coordination. • Sudden sever headache. Neurologic deficits of stroke Neurologic deficits Manifestations Visual field deficits •Loss of halve of the visual field •Unaware of persons or objects on side of visual loss •Neglect of one side of the body Difficulty judging distance •Loss of peripheral vision •Difficulty seeing at night. •Unaware of objects or the border of the objects •Diplopia Double vision Neurologic deficits of stroke Cont.. Neurologic deficits Manifestations Motor deficits •Hemiparesis •Weakness of the face, arm, and leg on the same side due to lesion on the opposite hemisphere •Hemiplegia •Paralysis of one side •Ataxia •Unsteady gait •Dysarthria •Difficulty in forming words •Dysphagia •Difficulty in swallowing Neurologic deficits of stroke Cont.. Neurologic deficits Manifestations Sensory deficits •Paresthesia •Numbness and tingling of extremity Verbal deficits •Expressive aphasia •Unable to form words that are understandable •Receptive aphasia •Unable to comprehend and spoken words •Global aphasia •Combination of both receptive and expressive aphasia Neurologic deficits of stroke Cont.. Neurologic deficits Manifestations Cognitive deficits •Short and long memory loss •Decreased attention span •Impaired ability to concentrate •Poor abstract reasoning •Altered judgment Emotional deficits •Loss of concept - Emotional labiality •Decrease tolerance to stress situation - depression - withdrawal •Fear-hostility-anger-isolated •Unable to form words that are understandable •Expressive aphasia Hemorrhagic stroke Intracerbral hemorrhage Subarchnoid hemorrhage Sites Bleeding occurs most commonly in the cerebral lobes, basal ganglia, thalamus, brain stem, and cerebellum may lead to rupture the wall of lateral ventricle and cause intraventriular hemorrhage which is fetal. Hemorrhage into the subarchnoid space. Causes Caused by hypertension brain tumor – trauma thrombolitic drugs and rupture aneurysms. Aneurysms, arteriovenous malformations, trauma, and hypertension. Hemorrhagic stroke Intracerbral hemorrhage Manifestations •Occur without prodromal symptom and during activity. •Severe headache – nausea vomiting. •Weakness of one side – slurred speech- hemiplegia – coma – hyperthermia - death Prognosis •Is poor 70% of patient die after stroke. •The extent of the symptoms various depending on the amount and duration of the bleeding. Subarchnoid hemorrhage •The patient may exhibit prodromal symptoms if the dilatation of the artery make compression on the brain tissues. Headache – lethargy – confusion – nausea – vomiting – neck pain -feverparalysis – coma – death. •Prognosis of patients is guarded because many patients experience another bleed within 2 weeks of the first occurrence. Temporal development of cerebrovascular accident Transient Ischemic attacks (TIA) • is characterized by brief episodes of neurologic manifestations, which clear completely in less than 24 hr. • It is though that the TIAS are a result of microemboli from atherosclerotic plaques found in extracranial arteries that lead to temporary cerebral ischemia. • Patients should consider TIAs as a warning sign of progressing cerebrovascular diseases. S & according to the site affected. • If the carotid artery is involved the patient may report loss of vision – transient hemiparesis – sudden inability to speak. Diagnostic studies • MRI or a CT scan • Brain scan • Lumbar puncture • Carotid ultrasound Diagnostic studies cont.. • Opthalmoscopy • Cerebral angiography • EEG • Other lab tests as urine analysis – coagulation profile – CBC – serum osmolarity – electrolyte – glucose – lipid profile creatinine and blood urea nitrogen. Managements of patient with stroke I-Medical managements - collaborative managements - Drug used - Rehabilitation care II- Surgical managements III- Nursing managements I- Medical managements • I- Collaborative care: 1-1 Prevention include: 1-1 stroke risk screening and health management for the well individual, management of modifiable risk factors, prevention of stroke for those with history of TIA, and prevention of addiction and • Health management focuses on healthy diet – weight control- regular exercises – no smoking- limiting alcohol consumption, routine health assessment, proper health management for patient with hypertension – diabetes, and cardiac problems. 1- Collaborative care cont….. 1-2 Drug therapy • Low dose of aspirin is used prophylactically because of its antiplatelet effects. • Daily use of platelets aggregation inhibitors such as Ticlopidine (Ticlid) as effective as aspirin in reducing the incidence of stroke. 1-3 Surgical therapy Surgical for the patient with TIA A- Carotid endarterectomy B- Transluminal angioplasty C- Extracranial – intracranial by pass 1-3 Surgical therapy Surgical for the patient with TIA A- Carotid endarterectomy( CEA) The atheromatous lesion is removed from the carotid artery to improve blood flow. CEA surgery is associated with reduction of stroke and vascular death. B- Transluminal angioplasty Is the insertion of a balloon to open a stenosed artery to permit increase blood flow. Is used to treat patients with stenosis in the carotid artery. Surgical therapy cont.. C- Extracranial – intracranial bypass (EC-IC) bypass is used for intracranial problems when obstruction cannot be removed directly the procedure involves anastomosing a branch for of an intracranial artery to an intracranial artery beyond the area of obstruction. Following the procedure these patients are at high risk for stroke and require closed, long – term assessment and management. 2- Acute care: A- Goal for collaborative care during the acute phase are: • Preservation of life • Prevention for further brain damage • Reduction in the level of disability B- To achieve this goals you should make initial assessment which includes assessment of : • ABC • Altered level of consciousness by use Glasgow coma scaleweakness, numbness, and paralysis of one side of the body • Speech or visual disturbance- unequal pupil • Sever headache - vital signs ( increased or decreased heart rate – respiratory distress- hypertension) • Facial drooping on affected side • Difficulty in swallowing • Seizure • Bladder or bowel incontinence • Nausea and vomiting C- Acute managements 1- Maintain air way patent by • Ensure patent air way • Remove denture • Elevate head of bed 30 degrees if no symptoms or shock. 2- Provide the patient with adequate oxygenation through nasal cannual – mask or intubation and mechanical ventilation 3- Establish IV access with normal saline to maintain blood pressure 4- fluid and electrolyte replacement must be controlled carefully • adequate fluid intake during acute care should be 1500 to 2000ml/day to promote perfusion to the brain and prevent overehydration • patient with ischemic stroke may be treated with hypervolmic hemodilution and volume expansion with crystalloids or colloids to decrease blood viscosity • Monitor urine output for the patient with stroke to detect urine retention caused by excessive secretion of Antiduritic hormone • IV solution with glucose and water are avoided to prevent increase of intracranial pressure and brain edema 5- management of increased ICP includes: • • • • • • • • Elevation of head Maintain head and neck in alignment position Avoidance of hip flexion Avoidance of hyperthermia to limit cerebral tissue metabolism and vasodilatation Treatment of pain Provide patient with laxative to prevent constipation Mannitol and furosemide medication may be used to reduce hypervolemia Dexamethasone may be used for patient with brain edema. I-2- Drugs managements of stroke • Thrombolitic therapy as tissue plasminogen activator • Platelet inhibition/anticoagulant as heparin – warfarinaspirin and ticlid • Other drugs: • as acetaminophen to treat hyperthermia • Anti seizure medication such as phenytoin • Calcium channel blockers as nimodipine to decrease effect of vasospasm and minimize tissues damage for patient with subarchnoid hemorrhage. Drug managements of stroke cont.. drugs action uses Side effects and nursing role Tissue plasminogen activator (t-PA) Produce localized fibrinolysis by binding to the fibrin in the thrombi •Is used to reestablish blood flow and prevent cell death for patient with ischemic stroke •Is effective if used within 3 hours of the stroke occurrence as defined by the onset of clinical manifestation •Patients should be screened carefully before treatment initiation . This include blood test for coagulation disorders – GI bleeding and CT or MRI to exclude hemorrhagic stroke -Cerebral hemorrhage -Frequent monitor vital signs to assess improvement or deterioration related to intracerebral hemorrhage -Control blood pressure is critical during treatment and 24 hours following treatment -No anticoagulants or antiplatelet drugs are administered for 24 hours after t-PA treatment. II- Surgical therapy Craniotomy surgery • for evacuation of hematoma if the diameter exceeds 3 cm and the Glasgow coma scale score decreases for patient with intracerebellar hemorrhage or aneurysm – induced hematomas. II- Surgical therapy CONT.. • Surgical clipping has been the traditional method for treatment of brain aneurysms. This method requires a neurosurgeon to perform a craniotomy (removal of part of the skull) to access the brain and blood vessels. The surgeon blocks blood flow to the aneurysm by applying a metal clip to its base, redirecting the blood flow away from the aneurysm. Then the wound is sealed again and closed. • Endovascular Coil Therapy Endovascular Coiling Therapy is a less invasive treatment method that produces better outcomes than surgical clipping in certain patients with cerebral aneurysm. • A catheter (small tube) is inserted into the patient’s femoral artery and advanced through the body until the aneurysm is accessed from the inside. • Small, soft platinum coils are inserted through the catheter into the aneurysm. Endovascular Coil Therapy (cont.) • The coils are packed into the aneurysm to block the flow of blood into the aneurysm. • By blocking the flow, the pressure on the aneurysm is reduced. • Over time, new tissue will grow at the opening of the aneurysm and blood flow will be diverted away from the aneurysm. The procedure is performed in under the guidance of fluoroscopic X-rays. The fluoroscopy allows the physician to visualize the vasculature and properly place the coils. • For patients with subarchnoid and intracerebral hemorrhage can involve bleeding into the ventricle of the brain. • Ventriculostomy and drainage relive hydrocephalus, which further damages brain tissue from increased intracranial pressure Rehabilitation care Rehabilitation team Nurse Physician Pharmacist Occupational therapy Physical therapy Speech pathologist Social worker Patient and family Vocational counselor Recreation al therapist Psychologist Nursing managements of patient with stroke 1- Subjective data: 1-Important health information: • Past health history ( cardiac problems – hypertension – diabetes) • Medication used ( oral contraceptive – anticoagulant- antihypertensive) 2- Functional health status: • Health perception-health management (positive family history- alcohol and smoking) • Nutritional – metabolic (anorexia, vomiting, dysphagia) • Elimination ( change in bowel and bladder patterns) • Activity – exercise ( loss of movement and sensation – weakness on one side • Cognitive perceptual ( numbness, tingling of one side of the body, loss of memory, alteration in speech, pain, headache, visual disturbance 2- Objective data: • General ( emotional liability, lethargy, apathy, and fever) • Respiration ( airway occlusion, labored or irregular respiration, tachypnea, apnea, loss of cough reflex. • Cardiovascular ( hypertension, tachycardia) • Gastrointestinal ( loss of gag reflex, bowel incontinence, decreased or absent bowel sounds, constipation) • Urinary ( urinary frequency, urgency, incontinence) • Neurologic assessment ( level of consciousness, cognition, motor ability, cranial nerve function, sensation, cerebrall abilities , deep tendon reflex.
