hemolysis
What is a reasonable lower threshold for platelet infusion? 40000 70000 100000 130000 150000
70000
not usually required until platelet count >50000
A pool of platelets raises platelet count by how much?

If a trauma pt is undergoing emergent laparotamy and receives and recieves 10 cell saver units plus 12 prbcs and no clots are in surgical field and venipuncture sites have begun to bleed, what’s the problem?
dilutional thrombocytopenia
What is the earliest coagulation disturbance seen in massively transfused patients?
hypofibrinigemia
What fibrinogen level is associated with coagulopathies?

b is IX
conditions producing decreased response to heparin
heparin bids and upregulates ATIII. ATIII then inhibits IX,X,XI, and XII
hepatic insufficiency-ATIII deficiency, ateriosclerotic disease, septicemia, pregnancy, HIT,
drugs-heparin, NTG interaction
