[HSF] old vs new blood

[Tea Acuff]

There are a lot of things going on here. Standardization, need for quantity, convenience, bias of fear of contamination over hope of effectiveness, bureaucratic inertia, etc. Regulation, also known as remote protocol, locks us into one  dominate option.

There is no way of decreasing the permissible shelf life of red blood cells without decreasing the supply and the blood banks are having difficulty already meeting the demand. We can help by decreasing the demand by not using so much blood. Maybe there is some way of altering the preservation processes to reduce the risks described in the NEJM. Paradoxically, the reduction of other risks associated with blood transfusion, i.e. hepatitis, AIDS, have led to increase in use of blood transfusion and the extension of shelf life limits was made to increase the supply.

Anyone see this weeks NEJM article from the CCF

conclusions:  "....transfusion of red cells that had been stored for more
than two weeks was associated with a significantly increased risk of
complications and worse short/long term survival"


no surprise, but is there anything we can do about it?

comments?
