My father nearly died twice because of the ban on blood transfusions. The second time he was saved ironically because of me being on this site. At the time he was admitted to the hospital, he had not signed his blood card yet (thank god). When the doctor heard he was a JW, he looked horrified and said to my mother and me "you realize he is probably going to die if he doesn't get a blood transfusion." I told the doctor that there were some things that JWs were allowed to take now and he said "is plasma one of them?" I thought it was and I said "I think so". He didn't bother waiting till we knew for sure and he administered the plasma which saved my father's life.
My brother-n-law died just over 4 years ago in part due to the ban on blood. He had a particularly horrific form of leukemia and there was no way he was going to survive it without blood transfusions keeping his counts up until he could get the stem cell transplant. With his red and white counts bottoming out, the idiots at the hospital administered a very concentrated bag of septra to him 2 days in a row (it was supposed to be diluted and it wasn't). Because his lungs were starting to break down because of the lack of oxygen, the septra went to the weakest part of his body---his lungs---and fried them. He was in a drug induced coma for a month before he died.
Even if the hospital hadn't screwed up, he would have been dead within a month or two anyway. With his red count being down to 71 (which is less than half of what it should be), there wasn't enough oxygen being circulated in his lungs and the tissue was breaking down. He eventually would have had a heart attack from lack of oxygen and died.
How these pricks at Crooklyn sleep at night knowing that this damn doctrine is needlessly murdering their own people is beyond me.
