Jehovah's Servants & Medical Personnel. Some Q's regarding blood & medical treatment.?

Also, if you google bloodless surgery you will find much info about Witnesses and their non blood use and substitutes. There is a lot of research being done at Loyola Medical Center close to where I live with substitute blood products. Also, Englewood Hospital in New Jersey has a lot of info. There are much better alternatives than whole blood. Disease free and a lot less expensive. With little or no side effects. Too bad the general public is so close minded to optional treatments. They are stuck in the past. Including many of the small town doctors I see here where I live.
