Q

ischemic penumbra

A

surrounding ischemic areas
Cells receive enough oxygen to remain alive for a limited time
Can be salvaged

protect the penumbra by increasing oxygen transport through surgery or medication

infarcted core

A

severe local ischemia
Tissue necrosis

17
Q

f-tPA

A

recombinant tissue plasminogen activator

Clot Buster

18
Q

when pt is a candidate for clot buster

A

onset is less than six hours
CT negative for hemorrhage
Not anticoagulated INR is less than 1.5

Keep blood pressure less than 185/110
hours since onset
<3 hours- IV TPA is substantial
3-4.5 hours - iv tPA moderate
4.5-6 hours - intra arterial tPA moderate

19
Q

when pt is not candidate for clot buster

A

keep bp <220/120
aspirin 325 mg chewed
DVT prophylaxis
-Heparin 5000 SQ BID
