The most important plasma protein is albumin, solutions of which are widely used in surgical practice. Experience shows that the use of albumin solutions is the "gold standard" for transfusion therapy of critical conditions caused by hypovolemia and intoxication.
For quite a long time preserved donor blood was considered the most efficient and versatile means for treating hemorrhagic anemia, hypovolemic states, disorders of various etiologies protein metabolism, etc.
Packed red blood cells (EM) - a blood component that comprises red blood cells (70-80%) and plasma (20- 30%) with impurity of leukocytes and platelets (hematocrit - 65- 80%). By one dose of the content of the erythrocytes red cell (270 ± 20 ml) is equivalent to a single dose (510 ml) of blood.
More than 23 million doses of blood components per year are poured into the United States.
