When I inquired about pre-donating my own blood prior to my AVR several years ago, I was *strongly* discouraged from doing so with assurances that the Blood Supply was MUCH safer than in years past due to more extensive testing, YADA YADA YADA. Apparently there is also a COST involved too, even for your OWN blood. I'm not sure I fully understand this.
As it turned out, I was fairly anemic post-op but just above the level where transfusion was recommended. I was sent home with Iron Pills instead.
I vaguely recall a post discussing this topic where one surgeon told his patient that the heart-lung machine does damage blood cells and by auto-donating before surgery, your own undamaged blood could be readministered after surgery. I've not seen any other such discussions. It seems like a reasonable idea to me. I wonder why it is not recommended more often.
