The complication of massive blood transfusion is:
The complications especially associated with massive blood transfusion are:
Dilutional coagulopathies (especially thrombocytopenia) and DIC.
Metabolic alkalosis: With standard transfusion (1-2 units) there may be acidosis or alkalosis but with massive transfusion there is always alkalosis due to citrate intoxication (1 molecule of citrate liberates 3 molecules of bicarbonate).
Hyponatremia (dilutional) is not the usual complication of blood transfusion but there is theoretical possibility after massive transfusion as stored blood does not have sodium.
