STROKE Flashcards
What is stroke
Sudden global or focal neurological
deficit resulting from spontaneous hemorrhage or infarction of the
central nervous system, with objective evidence of an infarction or hemorrhage, irrespective of the duration of clinical symptoms
……….. or …………….. is required to make the diagnosis and exclude other intracranial lesions that could present similarly
CT or
MRI scan
What is TIA
is a transient
episode of neurologic dysfunction caused by focal brain, spinal cord, or retinal ischemia.
There is no objective evidence of acute infarction in the affected region of brain or retina in TIA . T/F
T
Causes of cerebral infarction
Thrombosis
Embolism
Important risk factors of stroke in children
sickle cell disease
cyanotic heart disease
Risk factors of stroke
hypertension
diabetes
dyslipidemia
atrial fibrillation
smoking
Causes of stroke
Cerebral infarction
Intracerebral hemorrhage
Subarachnoid hemorrhage
Symptoms of stroke
Weakness of one side of the body including the face
Inability to rise up from a sitting or lying position
Sudden fall/collapse
Loss of speech
Loss of vision
Unconsciousness in some patients
Seizures
Severe headache and/or neck pain is seen in ……………..
subarachnoid hemorrhage
What is hemianopia
loss of one-half of visual field
Neck stiffness is seen in …………..
Subarachnoid hemorrhage
Signs of stroke
Paralysis of a limb
Facial paralysis
Initial flaccidity of limbs, but later spasticity and exaggerated reflexes
Hemianopia
Hemi-anaesthesia
Extensor plantar response
Dysarthria/dysphasia
Neck stiffness (in subarachnoid haemorrhage
What is Hemi-anaesthesia
loss of sensation of one-half of body
Treatment objectives in stroke
To limit the area of brain damage
To protect patients from the dangers of unconsciousness and immobility
To prevent aspiration
To treat the underlying cause if possible
To identify and manage modifiable risk factors
To institute measures to improve functional recovery To support and rehabilitate patients who survive with residual disability
To minimize adverse effects of drug therapy
Investigations in stroke
FBC, ESR
Blood glucose
Serum lipid profile
BUE/Cr
Uric acid
ECG
CT scan/MRI of the head
Chest X-ray
Non-pharmacological management of stroke
- Monitoring
- Establish adequate airway in unconscious patients
- Swallowing test in an upright position
- Insert nasogastric tube
5.Nurse in the lateral position with suctioning where necessary - Elevate head of bed
- Prevent pressure sores by regular turning (every 2 hours) in bed
- Maintain adequate hydration
- Keep patient clean and dry by frequent use of bedpan/urine pot, diapers, condom catheter as required. Urethral catheter should be used only if absolutely necessary
- Start physiotherapy as soon as practicable
How often should a stroke patient’s vital signs and neurological signs be monitores
Every 4 hours
