If you pay attention, the jws always focus on things like planned surgery when discussing the blood issue. Yes, it is possible to plan and execute a surgery without using blood transfusions. It is still much more of a risk to the patient, however.
When you have a trauma with massive blood loss, there is no way to keep a person alive without blood transfusions. The body cannot survive if the oxygen carrying capacity is reduced below a certain level. Volume expanders will not help.
This is what started my exit from the jws. They are dishonest when talking about bloodless medicine. It is really bloodless surgery they are talking about and there is no guarantee on that either.
It is not a peaceful death to die of massive blood loss. The heart beats at an extreme rate tring to get oxygen to the brain and vital organs. There is accompanied by horrific chest pain as the heart cannot get enough oxygen. The breathing follows suit, as the body tries to get more oxygen, until the person is in severe respiratory distress (gasping horribly for air).
I believe every jw should be required to watch a death caused by blood loss before they can sign away their right to use blood in an emergency and that of their children.
The society uses the bait and switch technique with the blood doctrine. They lie to their followers. They will have to answer for this.
