Lewisohn knew that sodium citrate was used to prevent clotting in specimens sent for pathologic investigation, and proved that it was safe for human blood transfusion in a concentration of 0.2% where a transfusion of 5g was not exceeded.
Which chemical was added to blood so it could be stored longer in 1916?
At the Rockefeller Institute in New York, Peyton Rous and J.R. Turner Jr. found that adding dextrose (sugar) to the citrate extended the storage time to four weeks.

How were blood banks used in ww1?
During World War I, Peyton Rous (1879-1970), together with J.R. Turner, Jr., developed a simple method for preserving whole blood so that it could be used for transfusion. At that time, blood transfusions in hospitals were done by directly connecting a blood vessel of a donor to one of a recipient.
Who invented blood banks?
Charles R. Drew
Charles R. Drew, the internationally famous inventor of the blood bank, had died because a White hospital refused to give him a blood transfusion.
When was the first blood depot created?

What is SAGM in blood bank?
Background and objectives: A dramatic decrease in the level of 2,3-diphosphoglycerate (2,3-DPG) takes place during the storage of whole blood (WB) in CPDA (citrate-phosphate-dextrose-adenine) and a similar decrease occurs during the storage of red blood cells (RBCs) in SAGM (saline-adenine-glucose-mannitol).
Is donated blood wasted?
More than 200 000 units of whole blood had to be thrown away after Americans donated 500 000 extra units in September and October. Donated blood is discarded if it remains unused after 42 days. It also says that all blood banks should keep a minimum 7-day supply of red blood cells in all communities at all times.

Why is Richard Lewisohn important?
Richard Lewisohn (July 12, 1875 in Hamburg – August 11, 1961 in New York) was a German-American surgeon. Working independently, Lewisohn’s contribution, in 1915, was to determine the optimal concentration of sodium citrate for preserving blood products without inducing toxicity (0.2% for transfusions not exceeding 5g).
