Disseminated Intravascular Coagulation (DIC) Correct Ans-activation of thrombin (that
converts fibrinogen to fibrin) to form clot.
- amniotoic fluid embolus
- trauma (exposure of endothelial tissue factor)
- infection/sepsis
- malignancy
,- extensive burns
- leukemia
fibrinogen, prothrombin, PLT F V/VIII reduced due to consumption
circulating thrombin also breaks down clot and produces FDP (fibrin degradation products)
Hemorrhage results from the anticoagulant action of FDP's and the depletion of coagulation
factors. (It really is a nasty trick. it uses up your clotting factors, then produces bleeding by
breaking down the clot that was built with the clotting factors. sort of a pathologic pyramid
scheme)
It really is a rampant activation of thrombin (a thrombin problem). the thrombin activate
fibrinogen, clots ensue, fibrinogen gets used up, PLTS get used up and the body goes on breaking
down the clots.
since the endpoint of the coagulation cascade is fibrin and all of the fibrinogen is being
consumed, lab values such as the INR can be "infinite" and PTT can be massive elevated because
there is no "end point" (fibrin clot) for those values
