Thank you Richard Oliver for doing your best to clarify in your posts what "Bloodless Surgery" means when hospitals refer to a medical technique that they use- as Bloodless Surgery.
I hope that my linked videos that explain and illustrate what "Bloodless Surgery" in fact is, clears up any misconceptions or colorful views on "Bloodless Surgery" to everyone.
All Bloodless Surgery means when a Hospital or doctor uses the term, is that the hospital will use as little blood as possible. And if possible zero blood, but that is not always the case.
So, a person trying to avoid a blood transfusion as much as possible during surgery, may opt to use this technique, but doctors do not guarantee that they won't use blood. They won't use blood if they don't need to but they will if they have to, and if they have to, they will try to use as little as possible -a fraction. And regardless of whether or not blood is used in the medical procedure, hospitals still use the term "Bloodless" to describe the therapy.
Some JW that want to avoid a blood transfusion may opt for this procedure with zero guarantee from the hospital that the hospital will not use blood, but with the assurance from the hospital that if blood is needed, the hospital will only use a fraction using this technique.
