Blood Collection and Transfusion Department

The section “Purchasing and processing of blood” is intended for receiving blood from donors in medical institutions of hospital collectors. It takes into account the indicators of collected blood. The donated blood is then moved around the unit for further distribution and transfusion to patients in need. Among the possible diseases, in particular for which blood and its components are prepared: - anemia of chronic diseases; - acquired hemolytic disease of newborns; - acute massive blood loss; — defects in the production of donor blood; - injury; — disturbances of electrolyte metabolism; - bacterial infections; - severe toxic damage; - oncohematological diseases.

The blood procurement and transfusion department is a division of a sorting and evacuation hospital or the main “blood sorting” hospital, engaged in the procurement of blood and its components, their storage, and delivery to medical institutions. The main unit is called the hospital's transfusion and distribution center.

Every year, doctors use about 2,500 tons of blood. Up to 70% of its composition is erythrocytes, all other cells (plasma, leukocytes, platelets) make up 30%. Of course, this blood not only saves lives, but also allows significant financial savings. This is why it is so important to stock up on blood.

Any surgical intervention involves blood loss. This means that doctors take a certain amount of donor blood from patients during the operation: the more it is lost, the larger the portion needed. If the patient has lost a lot of blood, much more is taken, up to 900 ml. When bleeding, blood is taken in several stages, increasing the portion over time. Accordingly, sometimes the surgeon spends much more time on one individual operation than on the entire postoperative period. And if the patient suddenly urgently needs additional surgery, the doctor may be faced with the fact that there will not be enough donor blood, because supplies are always limited by the number of portions. Such cases are recorded extremely rarely, so doctors tend to take an average amount of blood during surgery: not very little, but not very much. As a rule, this is approximately 400–500 ml per operation.
