I;ve just learned of this site today and I find it to be very informative. I have to present to a group of doctors and nurses in a hospital about the different alternatives to blood transfusions and I found quit difficult to find precises information on what I am looking for. If anyone could help me I would greatly appreciate it. I need information on the different alternatives, maybe not all, but the most popular ones; the risks involved in each such as complications and side effects, the benefits and anything else that might be important. I've been to different web-sites and it's hard to get exact information. We need to educate the medical field about the alternatives that are out there. If I can get some information on the DPA's I would appreciate that also.
