WHAT IS CVA/STROKE? CVA is the medical term for a stroke. A stroke
occurs when there is ischemia(inadequate
blood flow) to a part of the brain or
Hemorrhage into the brain that results in
Death of brain cells.
Functions like movement,sensation or
emotions that were controlled by the affected
area of the brain are lost or impaired<br>
03
incidence In India, 40 to 270 per 100,000 in the general population.
Third biggest killer in India after heart attacks and cancers.
In 2005, it is estimated that 5.7 million people died from stroke
Percentage is higher for people aged 65 and older.
Of those who survive, 50% to 70% will be functionally independent, 15-30% will live with permanent disability, 20% requires long term care after 3 months.<br>

pathophysiology 1.Regulation of cerebral blood flow
Impairment of cerebral autoregulation
Cerebral ischemia
Transient ischemic attack(Tia) TIA is a temporary focal loss of neurologic function caused by ischemia of one of the vascular territories of the brain, lasting<24hrs and often lasting <15mins
May be due to microemboli that temporarily block the blood flow
TIAs are a warning sign of progressive cerebrovascular disease
Signs include – numbness or loss of sensation,sudden inability to speak,diplopia,ataxia.
CT scan
Aspirin,clopidogrel,anticoagulants(e.g warfarin)<br>
Clinical manifestations Motor function – mobility,respiratory function, swallowing and speech,gag reflex
Communication – aphasia,dysphasia,dysarthria
Affect – disturbed emotional responses, depression or anxiety
Intellectual function – impaired memory and judgement
Spatial-perceptual alterations – incorrect perception of self,agnosia,apraxia
Elimination – urinary and bowel<br>
Collaborative care 1. Prevention:
Control of Hypertension
Control of Diabetes Mellitus
Treatment of underlying cardiac problems
No smoking
Limiting alcohol intake
Stenting of carotid artery
Transluminal angioplasty
Anticoagulation therapy for patients with atrial fibrillation<br>

2. Acute care:
Maintenance of airway
Fluid therapy
Treatment of cerebral edema
Ischemic stroke : merci retriever,tissue plasminogen activator(tPA)
Hemorrhagic stroke : surgical decompression, clipping/ wrapping/coiling of aneurysm
Embolic stroke : treatment of underlying cause<br>

Merci retriever<br>

Coiling and clipping of aneurysm<br>

Nursing management Ineffective tissue perfusion r/t decreased cerebral blood flow secondary to thrombus,embolus as evidence by decreasing GCS score and altered respiratory patern
Ineffective airway clearance r/t inability to raise secretions as evidenced by diminished breath sounds,ineffective cough
Impaired physical mobility r/t neuromuscular and cognitive impairment
Impaired verbal communication r/t residual aphasia as evidenced by refusal or inability to speak<br>
