Delivery of fetus ASAP
Why does hemolysis take place in severe preeclampsia?
Vasospasms in the CV system → destruction of RBCs AKA hemolysis
Why do liver enzymes become elevated take place in severe preeclampsia?
vasospasms cause a decrease in blood flow to the liver → tissue ischemia (low O2) and hemorrhagic necrosis
Why do platelets decrease in severe preeclampsia?
in response to endothelial damage caused by vasospasms (small openings develop in the vessels) → platelets aggregate at the site and a fibrin network is set up → leads to a decrease in circulating platelets
DIC
