|JJ ABEL 1857 – 1938|
Plasmapheresis is the therapeutic procedure in which the blood plasma is removed, purified and returned to the donor. Phlebotomy is the outpatient procedure of the withdrawal of an small amount of blood (about 1/2 lt) while at the same time a predetermined amount of intravenous fluid is administered (volume replacement). When relatively small amounts of plasma (about 600 ml) are removed the term plasmapheresis is appropriate but when more than this amount is removed then it is reccomended to infuse a colloid compound and for this the procedure is called plasma exchange.
