Power Point 2 Stroke And TIA Flashcards
AEIOUTIPS
A- Acidosis Alcohol E- Epilepsy I- Infection O-Overdose U - Uremja T- Trauma, Tumour, Toxin I- Insulin P- Psychosis, Poison S- Stroke , Seizures
What is the third leading cause of death
Stroke
Are strokes more fatal in men or women
Women
Who has more strokes men or women
Men have more until a woman reaches age 70
What is the brain sensitive to changes in
Oxygen, Glucose, Pressure, temperature
What does the motor and frontal lobe function
Motor control, movement,intelligence, personality, memory
What does the somatosensory cortex and parietal lobe function
Reasoning, language, sensation.
What does the occipital bulb control
Vision
What does the cerebellum, spinal cord and brain stem function (3)
Balance, coordination, fine motor control
What does the temporal lobe function
Speech, memory, hearing, emotions
Secondary cause
Problem caused by heart and lungs, the entire brain is effected
Primary Cause
Problem only the brain, then only part of the brain is effected
2 other brain disorders
Infection, Tumour
What is a CVA
Cerebrovascular Accident = Stroke
Ischemic Stroke
Most common type. Caused by embolism or thrombosis.usually atheroscleorsis
Left hemisphere stroke
Aphasia. Effects Brocs Area. Can cause paralysis of right side of body
Right Hemisphere Stroke
Can cause paralysis of left side of body. Can understand language but words may be slurred. Patients often oblivious to problem
Stroke treatments
Fibrinolytics = TPA and EVT. TPA must be given within 6 hours
Hemorrhagic stroke
Not as common. Caused by internal bleeding in brain. High risk groups are stress prone people and very high blood pressure. Very fatal
3 types of brain bleeds
Epidural bleed, subdural bleed (most common), subarachnoid (starts with headache)
3 findings in brain bleeds
Respiratory patterns, vital sign changes (Cushing triad), pupillary changes
Cushing triad 3 key findings
Irregular resps, bradycardia, systolic HYPERtension (widening pulse pressure)
TIA - Transient Ischemic Attack
When the body is able to breakup its own clot and patients symptoms disappear. Often indicates a serious medical condition that can turn fatal
What is a stroke called when symptoms go away on their own in less than 24 hours
TIA
5 conditions that mimic stroke
Hypoglycaemia, postictal state, subdural or epidural bleeding, brain tumor, migraines
Stroke screen criteria are positive when the following 3 criteria are met
- Blood glucose level is greater than 3.0 2. When the last time patient was seen normal to the time taken to stroke centre is less than 6 hours 3. One or more disabling findings are present
Stroke transport time
One scene for less than 15 min, load and go
Embolus vs thrombus stroke
Embolism- travels. Thrombus- remains.
What does the midbrain, pons and medulla control respectively
RAS(Waking and Sleep), RESPS(Breathing),ROM
RAS
Awake and sleep
Resps
Breathing
Rpm
Heart rate
