“Whole Blood? Seriously?” That is the reaction Dr. Mark Yazer gets when he talks about his current favorite blood product. He is on a mission to change your mind about this “old school” product!

In the remote history of transfusion medicine, life was simple. We had exactly one product. Someone could call and say, “hey, my patient needs red cells,” and our response: “Great, we’ve got some nice whole blood for ya!” Or, “this guy could really use some plasma.” Blood bankers: “We’ve got just the thing: Whole blood!”

However, around 50 years ago, we started separating whole blood into red cells, plasma, and platelets, and the age of “component therapy” was born. Hardly anyone used whole blood (except the military, where such use continued throughout numerous US combat campaigns).

Back to the Future

In 2017, as we learn more and more about what works and what doesn’t in trauma resuscitation, some are looking again at whole blood. Dr. Mark Yazer is helping to lead the charge toward the use of this product, specifically low-titer group O cold-stored whole blood, which he calls “the ideal pre- and early in-hospital resuscitation fluid!” In this episode, Mark returns to outline his case for that outrageous statement, making the following points (with time-stamps for where you can hear the points in the discussion):

  • There is a long history of transfusing whole blood [17:48]
  • It simplifies the logistics of resuscitation [25:10]
  • It is more concentrated than components [29:03]
  • Cold-stored platelets might be great! [33:37]
  • Nobody hemolyzes! [39:48]
  • Outcomes are not worse compared to component therapy [47:53]
