Stroke Flashcards
Definition
Sudden non-traumatic vascular insult to the brain. May be ischemic (embolic) or haemorrhagic (spontaneous bleeding)
Goal of Care
Identify reversible conditions, timely scene management and transport
Causes of CVA
- most common - ischemic (plaque or clot)
- spontaneous / hemorrhagic
TIAs
TIA (Transient Ischemic Attack) is a dramatic warning that the pt is at risk for stroke within days
It can be thought of as the neurological equivalent to unstable angina in the cardiovascular system
(often referred to as a “warning stroke”)
Conditions presenting w/ stroke like symptoms
Any condition that decreases blood flow to the brain
- symptomatic arrhythmia hypotension from GI bleeding or trauma
- hypoglycemia
- seizure disorders
Guiding Principles
Accurate recognition, timely scene management, transport, and notification are key principles in caring for stroke pts
Recognition - vital to determine the time of onset for symptoms - if not “last seen normal time” or woke up w/ symptoms
Timely transport - check BGL and correct before initiating transport
preferentially transported to emerge w/ CT imaging
Notify - at least 15mins to activate EVT (endovascular therapy)
Hot Stroke Definition
- Screen for stroke using the FAST-VAN tool
- Time since onset is less than 6 hours
or pt woke up w/ symptoms
Document finding and time of onset on the pt care record
Special Notes
- a pt may test normal on the FAST exam and still be having a stroke
(e. g c/o vision loss in both eyes affecting only part of their vision) - If a pt is on Coumadin, inform the treating physician immediately on arrival
the “thinness” of the blood (INR) is an important component in determining the treatment
Intervention Guidelines
EMR
- position pt
- supp O2
- IPPV if required
- Assess stroke symptoms
FAST VAN tool - Correct hypoglycemia
Glucogel 1 package - Ascertain onset or “last seen normal” time
- Minimize scene time
- Facilitate transport w/ notifications
PCP - FRONTIER trial enrollment, if indicated - Correct hypoglycemia Glucagon 1mg IM Dextrose 10-25mg D10W IV
