Clinical Approach to Stroke (Hon) Flashcards
What are the subtypes of stroke?
Which is more common?
1) Hemorrhagic Stroke
2) Ischemic Stroke (more common)
What are risk factors for atherosclerosis?
1) HTN
2) Smoking
3) Diabetes Mellitus
4) Hyperlipidemia
What cardiac dysrhythmia is a risk factor for stroke?
Atrial Fibrillation
Abuse of what drugs are risk factors for stroke?
1) IV drugs
2) Cocaine
3) Amphetamines
What are sx of Left Hemisphere stroke
Aphasia
Right sided sensory sx
Right sided motor sx
Right visual field cut
What are the sx of Right Hemisphere Stroke
Left Hemineglect (don’t recognize left side of body)
Left sided sensory sx
Left sided motor sx
Left visual field cut
What are the sx of cerebellar stroke?
Ipsilateral Ataxia, Vertigo, Nystagmus
What Sx are in Brainstem stroke?
Cranial Nerve findings with Contralateral hemisensory/hemimotor Sx, and Vertigo
What is common in acute ischemic stroke and in most cases should not be treated?
Why should it not be treated?
1) Acute HTN
2) Decreasing Blood pressure would decrease perfusion leading to further ischemia and thus infarction
What should the IV fluids not include in stroke patients because it is associated with worse neurologic outcomes?
Glucose
*ALL STROKE PATIENTS NEED IV ACCESS
Determining where the patient is on the NIH stroke scale is important for?
If using tPA or intra-arterial intervention
What does a score of < 10 on the NIH stroke scale entail?
A score > 20?
What are the main evaluation/Tx of stroke?
1) 2-3% risk of hemorrhage
2) 17% risk of hemorrhage
3) ABC, Elevate HOB to 30 Degrees, O2
What are some other causes that can present like stroke?
1) Seizure
2) Migraine
3) Hypoglycemia
4) Hepatic issues
When should tPA be given to a stroke patient?
Within 3-4.5 hours of the onset of symptoms
What are clinical situations in which warfarin (or one of the newer generation anticoagulants) is generally indicated?
1) Atrial Fibrillation
2) Prosthetic Valve
3) M.I.
4) Atrial septal defect
5) Hypercoagulable state
6) Large vessel disease
7) Aortic arch disease
