[Behavior of the blood calcium in operations during extracorporeal circulation].

The Authors analyse the variation of the calcium plasmatic concentration during extra corporeal circulation (E.C.C.). The Authors remind the importance of the calcium plasmatic concentration preserving a good cardiac output. They say that amount of calcium given assures a good plasmatic concentration and aid the cardiac output after E.C.C. The possible hypercalcemia after A.C.D. blood transfusion doesn't compromit the cardiovascular function.
