No benefit to pre-meds before transfusions

By  |  November 12, 2008 | 

This is the largest double-blind randomized controlled trial designed to determine the utility of tylenol and diphenhydramine in reducing the incidence of allergic or febrile non-hemolytic transfusion reactions (abstract). Included patients were those admitted to a leukemia or BMT unit with no prior transfusion reaction, and all transfusions were leukoreduced. They found the incidence of reactions was 1.5/100 transfusions in the placebo group and 1.4/100 transfusions in the intervention group. Based on this (and other smaller and older trials), there is no benefit to pre-meds in cancer patients receiving leukoreduced transfusion products. As an editorialist states, it would be nice to see corroboration in a more general medical population, but for now, routine pre-med use should be discouraged (editorial)

  As you can see, no glamour shots for this month’s post. I knew it would come at some point, and my first hospitalization related to my CLL came in a big way in mid-July. Given my interest in global health, it was only fitting that I managed to get sick while out of the […]

This large multicenter trial randomized patients with acute VTE to apixaban (10mg BID for 1 week, followed by 5mg BID for 6 months) versus conventional therapy (lovenox-warfarin). The primary outcome was similar between groups (symptomatic VTE or death related to VTE), but major and minor bleeding occurred significantly less often with apixaban. Apixaban is a […]
