Stroke Flashcards
sudden onset of focal neurologic deficit caused by disruption in the blood supply to the brain lasting >24 hours
stroke, CVA, brain attack
sudden onset of focal neurologic deficit caused by disruption in the blood supply to the brain lasting
TIA
cause of ischemic stroke
thrombosis or embolis
cause of hemorrhagic stroke
subarachnoid or intracerebral bleeds
people with these 2 things are at high risk for embolic stroke
chronic a-fib
prosthetic heart valves
people with these disorders are at high risk for thrombolic stroke
atherosclerosis, DM, HTN
sxs of stroke
numbness of face, arm or leg
trouble seeing
confusion, trouble speaking or understanding
trouble with walking, dizziness, loss of balance or coordination
sudden severe HA
acute management goals for stroke pt
maintain life
prevent further brain damage
reduce disabilities
maximum time after onset of sxs that tPA can be given
3 hours
must have a score of what on the stroke scale to get tPA
> 22
you can see this type of stroke on a CT initially
hemorrhagic
tPA cannot be given for these reasons
taking coumadin surgical procedure within last 14 days aneurysm neoplasm head injury/surgery in last 3 mo. GI/GU bleeding
blood glucose must be above what to given tPA and why
50 or above because hypoglycemia can mimic signs of stroke
following a stroke, pts will be given these meds
antiHTN heparin/coumadin antiplatelet dilantin (reduce seizure) decadron nimodipine
prior to giving tPA you must make sure all what have been completed
invasive procedures
these factors increase the risk of hemorrhagic stroke
HTN
alcohol/drug use
anticoagulants
blood clotting disorders
sxs of subarachnoid hemorrhage
usually none but some may be: "worst HA of my life" V/N photophobia stiff neck loss of consciousness
