Flashcards in Acute stroke managment Deck (23):
1

stroke risk with age

doubles every deade after 55

2

def of stroke

clinical syndrome of sudden onset focal neuro deficift presumed to be due to vascular

3

4 questions for stroke diagnosis

1. is it stroke?
2. where is lesion
3. type of lesions (ischemia Vs. hemmorage
4. what is etiology

4

5 steps if stroke diagnosis

1. Hx and exam
2. labs (CXR, INR, CBC, HBA1C)
3. image brain
4. image vessels
5. rule out cardiac source

5

5 stroke mimics

1. any focal lesion (tumor, demylenations)
2. post ictal
3. old stroke
4. hysterical conversions
5. migraine

6

def of TIA

sudden onset of focal neuro that resolve within 24 hours AND no evidence of infarct on imaging

7

5 signs of carotid stroke

1. retinal ischemia
2. aphasia
3. cortical sensory loss
4. apraxia
5. sensory motor deficit

8

5 signs of verti-basilar

1. diploplia
2. coma
3. crosss sensory loss
4. bilateral motor signs
5. isolated field defect

9

what are prevalence of stroke types

1. 80 ischemic
2. 10 sub arach
3. 10 into parenchyma

10

*** what shows on CT in 2 types

hemor- shows blood
isch - very subtle

11

what are only 3 wihte things on CT

1. blood
2. contrast
3. calcified tissues

12

5 goals in acute isch stroke mgmt

1. make rapid and acc. diagnosis
2. reduce infarct size
3. avoud secondary complications - sepsis, embolism
4. secondary prevention
5. educate and rehab

13

what happens as ischemis prgresses

synaptic failure>membrane failure

14

what is penumbra

area that can still be saved around the infarct

15

what is treatment window

4.5 hours

16

what are physical neuroprotection measures

1. hypothermia
2. avoid hypotension, hyperglycemia, fever

17

drugs to retard ischemic cascade

1. gluatmate antag.
2. free radical scavengers
3. NO synthase antag

18

what is risk of TPA

hemmorage

19

what is TPA NNT

10

20

4 primary stoke risk factors

1. hypertensiokn
2. diabetes
3. dyslipidemia
4. smoking

21

what is risk of stroke post -TIA

90 days ~ 10%

22

5 possible secondary preventions

1. antiplatelets
2. anticoagulants
3.carotid endartectomy
4. carotid angio

23

4 signs of stroke that can be mixed

1. dysarthia
2. dysphagia
3. pure motor
4. pure sensory
