A couple of months ago, my mother (in her mid-80s) had internal bleeding. The doctors at the hospital could not locate the source of the bleeding, and my mother made it clear that she would not accept transfusions. I found out that this was happening when I got a call from her the next morning, where she was basically saying her good-byes because the doctors feared that she would be dead before the day was out.
They managed to save her by giving her fluids and a medication that apparently can slow internal bleeding, which they use after certain surgeries (first I ever heard of this!). By the end of the day, the bleeding (which they never did locate the source of) stopped and she slowly began to recover her red blood cell count. She left the hospital a couple of days later.
So, it seems as if the no-blood transfusion edict remains as it is. JWs can get almost any part of blood if it is isolated, but not blood itself. Although, to be honest, I think that if they decided that transfusions were okay, she would probably not want to get one. Too much time believing in the old stance to accept any changes.
