AuntBee: bloodless medicine hospitals...the receptionist that answered - to me, totally seemed like a JW...
There aren't really "bloodless medicine hospitals". There are "bloodless centres" that are basically admin centers attached to hospitals. At one time all of these bloodless centres were founded and staffed by JWs and most still are.
The bloodless industry consists of JWs and their medical cronies. It is mostly based on ideology rather than good science, regardless of it's somewhat spurious claims.
Bloodless surgery relies on blood transfusion technology and blood fractions. There are limitations to the practice and to the type of patient that qualifies for it.
