A blood bank is a center where blood collected as a result of blood donation is stored and retained for later use in blood transfusion. The term "blood bank" typically refers to a division of a hospital where blood storage occurs and where appropriate testing is performed (to reduce the risk of transfusion-related adverse events). However, sometimes it refers to a collection center, and in fact some hospitals also perform collection.
For blood donor agencies in several countries, see the list of blood donor agencies and the list of blood donor agencies in the United States. All blood or blood with RBC is transfused to a patient with iron deficiency anemia. It also helps to improve oxygen saturation in the blood. It can be stored at 1.0 ° C-6.0 ° C for 35-45 days. It is transfused to those suffering from low platelate count. This can be stored at room temperature for 5-7 days. This is indicated for patients with hepatic impairment, severe infections or severe burns. Fresh frozen plasma can be stored at a very low temperature of -25 ° C for 12 months.
While the first blood transfusions were made directly from the donor to the recipient prior to coagulation, it was discovered that by adding anticoagulant and cooling the blood it was possible to store it for a few days, thus opening the way for the development of blood banks. John Braxton Hicks was the first to experiment with chemical methods to prevent blood clotting at St Mary's Hospital in London in the late 19th century. His attempts, using soda phosphate, however, were unsuccessful.
The first non-direct transfusion was performed on 27 March 1914 by the Belgian doctor Albert Hustin, although it was a diluted solution of blood. Argentine physician Luis Agote used a much less diluted solution in November of the same year. Both used sodium citrate as an anticoagulant.
