chapter 4-3 Flashcards
1
Q
heparin-induced thrombocytopenia
A
plt destruction 2ndary to heparin use
2
Q
DIC
A
widespread microthrombi-ischemia/infarction
LABS- dec plt count, incre PT/PT, dec of fibrinogen. Microagiopathic hemolytic anemia, INCREASE D_DIMER
3
Q
Significant lab finding in DIC differ from
A
D- DImer from splitting of cross linked fibrin NOT fibrinogenin
4
Q
fibrinolysis normally
A
TPA converts plasminogen to plasmin cleaves fiibin and serum fibrinogen and helps with PTT aggregation
5
Q
what activates/inactivates plasmin
A
activates- tpA
inactivates alpha 2 antiplasmin
6
Q
fibrinolysis problems
A
increas PT and PTT = plasmin kils coagulation factors.
increase BT
normal PLts
NO INCREASE IN D-DIMER
