A longer duration increases the risk of bacterial growth. If the transfusion due to heart failure or fluid overload must be given slowly, so the units should be divided from the blood bank in smaller quantities. For children, a unit of blood can be used in smaller, sterile bottled amounts that can be used for several days. Thereby, the exposure to different donors is reduced. The patient should, especially during the first 15 minutes of transfusion, be closely monitored. This includes the recording of temperature, blood pressure, pulse and breathing rate. The periodic monitoring is continued during and after the Transfusion, wherein the fluid balance is detected. The patient should also be kept warm. can freeze a sign of a transfusion reaction be.
