Whole Blood in Trauma Resuscitation: What Did TOWAR and SWiFT Change?

Whole blood has made a remarkable comeback in trauma resuscitation. Physiologically, the rationale is compelling, and observational studies have suggested improved survival. But the recent randomized TOWAR and SWiFT trials have challenged the assumption that whole blood is clearly superior to component therapy.

In this episode of Trauma ICU Rounds, we review the rationale for low-titer group O whole blood (LTOWB), the major observational data supporting its use, what TOWAR and SWiFT actually showed, and how these findings should influence contemporary damage-control resuscitation.

Topics include:

•  Low-titer group O whole blood (LTOWB) 
•  Observational versus randomized evidence 
•  TOWAR and SWiFT 
•  Whole blood versus balanced component therapy 
•  Integrating whole blood into massive hemorrhage protocols 
•  Calcium, warming, TXA and hemorrhage control 
•  RhD considerations in females of childbearing potential 

The central question: whole blood clearly works as a resuscitation product—but is it actually better than excellent component therapy?
