Dear Kristi:
I will only tell you of what happened to my husband.
He was pretty sick before his surgery, and his surgeon also thought he should donate his own blood. We went to the Red Cross for the first donation, and frankly that went OK. Two weeks later, he was actually even sicker, we went in, and they refused to take his blood, as his pulse was "thready". They strongly suggested that I take him immediately to the ER. He refused to go. I then drove to his PCP's office, and insisted his Dr. check him out, as he was due for the surgery in ten days. The Dr. then called his cardio, they gave him oxygen for about two hours, and sent him home. He was anemic by this point. We were eventually charged $500.00 for the one unit of blood, which they did not use during the surgery. Needless to say he was VERY anemic after the surgery, and remains slightly anemic to this day. He absolutely did not want anyone else's blood except his own, or mine if need be. I think he would have been in better condition going in to the surgery had he NOT donated his own blood. He would have been stronger.
That's my two cents!
