Blood Products and Transfusion: July 2006

Hello all. It’s been a while between projects – here’s a new FAQ article on blood: components, transfusion, bleeding situations, coag- and anti-coagulation – you get the idea. For this one we asked for audience participation, which came mostly from two sources (who also seem to enjoy this kind of self-torture) – SF and Becky. The material after their answers is mine, and I did the editing, so any errors in this article only come from me. They get a lot of thanks for going over the questions in detail, and taking the time to provide their own answers. They may not yak as much as I do, but they’ve both been there, done that, and wear the t-shirt. (“My mom transfuses blood in emergencies, and all I got was this lousy t-shirt.”) Thanks, ladies.

As usual, please remember that these articles are not meant to be official references, but to represent what an experienced ICU preceptor passes on to a new RN orientee. (Plus some homework to fill in the gaps.) Let us know when you find errors or omissions, and we’ll fix them right away. Thanks!
