ILoveTTATT: Well, the report says that most of the witnesses rejected ALG... globulin... because they considered it to be a blood product. So either it was banned outright or we had some really stupid JW's who rejected stuff that was already allowed...
Fractions were "allowed" in WT literature as early as 1978. (the study we have been discussing started in 1979)
Watchtower June 15, 1978, Questions from readers:
What, however, about accepting serum injections to fight against disease, such as are employed for diphtheria, tetanus, viral hepatitis, rabies, hemophilia and Rh incompatibility? This seems to fall into a ‘gray area.’ Some Christians believe that accepting a small amount of a blood derivative for such a purpose would not be a manifestation of disrespect for God’s law; their conscience would permit such. (Compare Luke 6:1-5.) Others, though, feel conscientiously obliged to refuse serums because these contain blood, though only a tiny amount. Hence, we have taken the position that this question must be resolved by each individual on a personal basis. We urge each one to strive to have a clear conscience and to be responsive to God’s guidance found in His Word.—Ps. 119:105.
In 1981, Gene Smalley and the WT doctor, Dr. Dixon, published an article that was presented to the medical community (and has been quoted ad nauseum ever since...) that also claimed that acceptance of blood "fractions" was a personal decision:
...Witnesses' religious understanding does not absolutely prohibit the use of components such as albumin, immune globulins, and hemophiliac preparations; each Witness must decide individually if he can accept these.
Dio:
When did they start allowing cell salvage???
When Haemonetics developed the first salvage machine in the mid-70s. Of course, the org claimed that it was only okay if "the blood wasn't stored". How this is even possible is beyond me - storage is always involved - the patient's blood isn't returned to their body right away - of course there is a storage period. It can't be avoided. However, Smalley/Dixon said this to the medical community in 1981:
Techniques for intraoperative collection or hemodilution that involve blood storage are objectionable to them. However, many Witnesses permit the use of dialysis and heart-lung equipment (non-blood-prime) as well as intraoperative salvage where the extracorporeal circulation is uninterrupted; the physician should consult with the individual patient as to what his conscience dictates.
