I think that the change of view concerning ANH is explain in a very sublte way on the wiki of NoBlood.org (strange name when we consider the reality !!!)
Take a look at http://www.noblood.org/wiki/Acute_Normovolemic_Hemodilution
Explaining the current procedure of ANH it is said:
" Step 5 Once a whole blood bag is full, it must be disconnected, the tubing sealed, the bag labeled and kept in a safe location in the OR. (Figure 6) The blood bags must remain under the purview of the anesthesiologist at all times, ensuring that administrative error does not occur. This blood is typically stored at room temperature (20 degrees C) for up to 6 hours. After 6 hours, this blood product should be refrigerated at zero degrees C, in accord with American Association of Blood Banks (AABB) guidelines. The bags should be intermittently agitated to ensure that sludging or clumping of red blood cells or platelets does not occur."
After that he explain the now old view of JW concerning ANH:
"When perforning ANH for patients with religious-based objections to allogeneic blood, such as Jehovah's Witnesses, ANH can be performed with special modifications. The whole blood collection circuit and fluid administration system have to remain continuous with the patient's intravascular compartment."
But after the explaination of the concept of 1989, it is added the new concept:
"It should also be noted that a closed circuit system may not be absolutely required in all situations. During ANH some Jehovah's Witnesses might allow the blood to be withdrawn and held close by for reinfusion toward the end of the procedure. This is considered a matter of personal choice or conscience."
So return now to Step 5 !!! it is so a real storage of few unit of whole blood even after 6 hours, the "transfusion" here is called "reinfusion" of whole blood. Technically it is true, but in the view of the theology of JW before 2005 or perhaps 2000, it should be called a blood transfusion !!!
