The preserved blood for transfusion can be kept in a refrigerator at 5°±1°C to 21 days. However, it is not sure that the temperature is being kept all the time at this range because of transportation, operating room procedures or disturbances in the refrigeration systems.
The effects of temperature were determined at 5°, 21° and 37°C from 0 to 48 hours on the properties of red cell membrane resistance, sodium and potassium content in plasma and ATP and 2, 3-DPG contents in blood.
At 37°C the changes are so big that 5 hours correspond to a week storage of the blood and 8 hours to 2 weeks of storage. 8 hours at 21°C correspond to a week of storage. The biggest change was shown on the decrease of 2, 3-DPG content.
