Trauma blood management: avoiding the collateral damage of trauma resuscitation protocols.

Abstract

The use of high ratios of red blood cells to platelets and plasma in trauma resuscitation protocols is quickly gaining favor in civilian trauma centers. The use of higher ratios of coagulation factors to red blood cells has been shown to improve outcomes in both military and civilian centers, but does the evidence support the use of a 1:1:1 ratio, as has been suggested? There is growing evidence that the use of such high ratios may be excessive and potentially harmful, and there has not been enough emphasis on the other components of evidence-based "damage control" resuscitation.
