Donor survey to assess facial flushing during automated red cell collections and medication use
2011
Background: We conducted a donor survey to assess the occurrence of
facial flushingand other symptoms during automated 2-U red cell collections (2RBC) and
plateletpheresis(PLT) procedures and evaluated the possible association of the reactions with angiotensin-converting enzyme (
ACE)
inhibitorsor with the collection technology. Methods: An online survey was developed using Zoomerang to capture details of the donors' experience and medication use after 2RBC or PLT donations in regional blood centers of the American Red Cross. Results: Between 12/16/09 and 4/19/10, 1,299 donors in five American Red Cross blood center regions completed an online survey (739 2RBC, 4.2% total registrations; 560 PLT, 2.3% total registrations).
Facial flushingwas reported by 29 donors, and was more likely associated with 2RBC than PLT procedures (3.0% vs. 1.3%, P = 0.03).
Facial flushingwith 2RBC donation was reported by eight of 72 (11%) donors on
ACE inhibitors; and 14 of 667 (2%) donors who were not taking
ACE inhibitors(P = 0.001). The incidence of
facial flushingreactions with PLT donation was less than 2% whether donors reported ACEI inhibitor use or not. More than 95% of the donors reported their intent to donate again, regardless of symptoms. Conclusion:
Facial flushingwas more often reported by 2RBC donors taking
ACE inhibitorsthan other donors [11% vs. 2%; P = 0.001]; and was uncommon among PLT donors, irrespective of
ACE inhibitoruse (<2%). All blood donors should be informed of the potential for common, minor side effects of the collection procedure and the possible but rare occurrence of more medically serious complications. J. Clin. Apheresis, 2011. © 2011 Wiley-Liss, Inc.
