What is a Stroke?

“Stroke” is a term used to describe
neurological changes lasting more
than 24 hours caused by an
interruption in the blood supply to a
part of the brain. If the blood flow
ceases for an extended period of time,
the cerebral tissues involved die
causing permanent neurological
deficits.

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

narrow enough to block its
passage

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
