Diner: "I would like a cup of coffee, please."
Waiter: "I'm very sorry, sir, but I'm afraid we're fresh out of coffee today; our coffee maker has been completely exhausted."

Cool-stored blood transfusionIn 1916, blood that had been stored and cooled was used for the first time in a blood transfusion performed by the R.A.M.C. The procedure was very successful. Blood transfusions had been made previously, but this demonstrated the value of cooling to store blood. Until 1913, direct transfusion was the only technique practiced, despite being a difficult and time-consuming method, requiring trained personnel and was impractical for as a procedure in sudden emergencies. In the last two years of World War I, British surgeons benefitted from knowledge derived in the U.S. Use of blood collected and stored in advance of the need as casualties arrived facilitated transfusions as needed.[Image: blood transfusion was a mature procedure to treat casualties in World War II] |
