If the blood flow ceases for an extended period of time, the cerebral tissues involved die causing permanent neurological deficits. 15 CEREBRAL CIRCULATION LOCATION 17 http://www.nlm.nih.gov/medlineplus/ency/imagepages/18009.htm CLINICAL MANIFESTATIONS COMMON EFFECTS OF A RIGHT HEMISPERIC STROKE Left visual field loss (homonymous hemianopsia) Dysphagia Usually retain language ability but may have difficulty producing speech (dysarthria) Left-sided weakness (hemi paresis) or paralysis (hemiplegia) Sensory impairment Denial of paralysis, “forget” or “ignore” objects or people on their left side (neglect) Impaired ability to judge spatial relationships (misjudge distances and depth leading to falls, unable to guide hands to button a shirt, problems with directions such as up / down, no concept of time) Impaired ability to locate and identify body parts Short-term memory impairments (difficulty remembering new information) and apraxia (inability to carry out learned movement in the absence of weakness or paralysis) Behavioral changes such as impaired judgement or insight into limitations, overestimate physical ability, impulsivity, inappropriateness and difficulty comprehending and expressing emotions COMMON EFFECTS OF A LEFT HEMISPERIC STROKE Right visual field loss (homonymous hemianopsia) Dysphagia May develop aphasia (loss of language including spoken, written, reading and comprehension) but may also have dysarthria Right-sided weakness (hemiparesis) or paralysis (hemiplegia) Sensory impairment Usually have normal perception Usually judgement is intact with good insight into limitations Short-term memory impairments (difficulty remembering new information) and apraxia (inability to carry out learned movement in the absence of weakness or paralysis) Often develop a slow and cautious behavioral style. They need frequent instructions and feedback to complete tasks Better able to comprehend and express emotions TYPES OF STROKE Ischemic 80 - 84% Caused by blockage of the artery resulting in reduction of blood flow and cell death Include thrombotic, lacunar, embolic cryptogenic CT scan negative until a few days post stroke then hypodense area - indicates infarction THROMBOTIC STROKE Atherosclerosis in cerebral arteries Similar to CAD – leading to MI Atherogenesis – decades long process In thrombotic stroke lumen of artery narrows to point of obstruction LACUNAR STROKE Atherosclerosis in cerebral arteries Similar to CAD – leading to MI Atherogenesis – decades long process In thrombotic stroke lumen of artery narrows to point of obstruction EMBOLIC STROKE A clot travels from source outside of brain Encounters vessel with lumen narrow enough to block its passage Clot lodges there, blocking blood flow Most common source - heart Common conditions - atrial fibrillation, valvular disease, ventricular thrombi, atherosclerosis of the proximal aorta HEMORRHAGIC STROKE A clot travels from source outside of brain Encounters vessel with lumen narrow enough to block its passage Clot lodges there, blocking blood flow Most common source - heart Common conditions - atrial fibrillation, valvular disease, ventricular thrombi, atherosclerosis of the proximal aorta EMERGENCY MANAGEMENT Neurological vital signs Blood pressure Glycemic control Control of body temperature Oxygenation Hydration HEMORRHAGIC STROKE Treatment based on the underlying cause of the bleed and the extent of brain damage Treatment includes medication and surgical intervention Management of ICP with antihypertensives or surgical evacuation of hematoma In patients with ruptured aneurysm - clip or embolization Strategies to prevent a stroke -Maintain a healthy weight - eat a reduced-fat diet – – – – – Reduce alcohol intake to 1-2 drinks / day Exercise - 30 minutes 3-4 times / week Become smoke free and drug free Management of hypertension (ACE inhibitors) Management of heart disease (anticoagulants), diabetes and hyperlipidemia (statins) – Carotid endarterectomy may be indicated with stenosis – Antiplatelets for plaque / clot formation NURSING DIAGNOSIS Ineffective tissue perfusion r/t decreased cerebral blood flow or cerebral edema Ineffective airway clearance r/t inability to raise secretions ,ineffective cough Impaired physical mobility r/t neuromuscular and cognitive impairment, decreased muscle strength and control Impaired verbal communication r/t residual aphasia Risk for aspiration r/t inability to protect the airway Altered sensory perceptual r/t altered LOC, impaired sensation and vision. Unilateral neglect r/t visual field deficit and sensory loss on one side of the body Impaired urinary elimination r/t impaired impulse to void or manage tasks of voiding Impaired swallowing r/t weakness or paralysis of affected muscles Situational low self esteem r/t actual or perceived loss of function. NURSING MANAGEMENT Airway management/ventilator management Assessment and evaluation of neurologic status to detect patient deterioration Blood pressure management General supportive care and prevention of complications associated with: – Dysphagia, HTN, hyperglycemia, dehydration, malnourishment, fever, cerebral edema, infection, and DVT, immobility, falls, skin care, bowel and bladder dysfunction. SIGNS OF ↑ ICP Early signs: – Decreased LOC – Deterioration in motor function – Headache – Changes in vital signs Late signs – Pupillary abnormalities – Changes in respiratory pattern – Changes in ABG’s Airway management adequate O2 saturation Preventing increased ICP and providing supportive care. Hourly vitals/neuros including ICP, CPP, CVP. Maintaining BP to ensure adequate CPP Seizure precautions Antibiotic prophylaxis Stabilization Prevention of complications Monitoring neuro status Family support and education REHABILITATION Do with the patient not for the patient Management of impairment disability or handicap Patient family and others Positioning Exercise Skin Communication Swallowing Elimination
