impaired cerebral circulation
Dination
When there is less oxygen and glucose reaching the brain which can cause brain damage and neurological problems.
Causes
drowning.
choking.
suffocation.
high altitudes.
pulmonary diseases.
anemia.
Cerebral embolism
:An embolic stroke occurs when a blood clot that forms elsewhere in the body breaks loose , it travels to the brain through the bloodstream.when the clots lodges in an artery & blocks the blood flow thus causing stroke.
Pathophysiology
Embolic strokes are usually caused by a blood clot that forms in the body(embolus) and travels through the blood stream to the brain. this stroke usually result from heart disease or heart surgery and it occurs without warning
signs and symptons
speech difficulties
numbness or weakness of the arm
drooping on one side of the face
face , leg , arm and on each side numbness
Causes
cerebral embolism is a blood clot (thrombus) that starts from the hear or blood vessel where clots originate and sto in an artery that lead to or rests within the brain
nursing management
Position the patient to prevent contractures, relieve pressure, attain good body alignment and prevent compressive neurophathy
Administer medication as prescribed
Cerebral thrombosis
A stroke-like attack that, despite resolving within minutes and sometimes hours, require immediate medical attention to differantiate from the actual stroke
Pathophysiology
underlying cause of a TIA often is a buildup of cholesterolcontaining fatty deposits called plaques (atherosclerosis) in an artery that supplies oxygen and nutrients to the brain .Plaques can reduce the flow of blood throuh the artery or lead to the formation of clot
Causes
This blockage is usually caused by a blood clot that's formed in the body and travel to the blood vessels that supply the brain, it may also be caused by the pieces of fatty material or air bubbles
Clinical manifestation
walking difficulties, muscle weakness, problems with coordination
feeling faint, light-headedness, or vertigo
slurred speech or impaired voice
blurred vision or loss of sight
muscle weakness or numbness
difficulty swallowing, mental confusion
NURSING MANAGEMENT
Maintain a comfortable, quiet and relaxing environment ffor the patient
Avoid activities that could cause blood pressure fluctuations such as physical exercise
Administration of medication as ordered by the doctor
Cerebral thrombosis
Pathophysiology
Cerebral venous thrombosis (CVT) is a blood clot of a cerebral vein in the brain.This vein is for draing blood from and to the brain, if the blood collected in this vein it begins to leak into the brain tissues causing heamorrhage or severe brain
causes
Collagen vascular diseases like lupus, Wegener's granulomatosis and bechet syndrome.Obesity, low blood pressure and inflamatory bowel disease such as ulcerative colitis
Clinical manifestations
Blurred vision
Fainting or loss of consciousness.
Loss of control over movement in part of the body.
Seizures
Headache
Nursing management
Encourage the patient to maintain balance in a sitting position, and standing and try walking if the balance is adequate
Position the patient to prevent contractures and to relieve pressure, attain good body alignment to prevent compressive neurophathys
Apply splint at night to prevent flexion of affected area
Encourage personal hygiene
