Allergic reactions? They are SO BORING! Not so fast, my fine learners! New information suggests otherwise.Dr. Will Savage from Harvard University joins Dr. Chaffin to discuss Allergic Transfusion Reactions (ATRs).
Allergic reactions have become pretty widely known as “nuisance reactions” to blood bankers and clinical staff (“Dang it! Another patient with hives!”), and it’s easy to think that we fully understand them. However, Dr. Savage and his colleagues (primarily from his previous position at Johns Hopkins University) have spent the last few years studying allergic reactions in-depth, and they have shown in numerous recent publications that we don’t yet fully “get it” with ATRs. In fact, what he has to say may surprise you! Dr. Chaffin says, “Speaking personally, the work that Will has been involved in (much of which is referenced in the links at the bottom of this page) has completely changed the way I look at these reactions! Yes, they are a nuisance, but they are a nuisance that really impacts patients to a much greater degree than I understood in the past.”
