Our July, 2019 Quick Question was directed to trauma centers, and attracted 22 responses. The question was…
How does your institution manage trauma-induced coagulopathy?
- Crystalloid plasma expanders 3 (14%)
- pRBCs 2 (9%)
- 1:1:1 components 12 (54%)
- Whole blood 2 (9%)
- Tranexamic acid 3 (14%)
Thank you for your answers. Arising from military experience, a handful of facilities are returning to group O or group-specific whole blood, reasoning that whole blood provides all the components in the right proportion. It appears that the platelets in refrigerated whole blood provide activity in vivo even though they may not respond to aggregometry agonists.
Most trauma centers have moved from crystalloid plasma expanders and pRBCs, which raise the ristk of trauma-induced coagulopathy, to 1:1:1 ratio of pRBCs, plasma, and platelet concentrate. Trauma centers have built the 1:1:1 ratio into their massive transfusion protocols, reckoning that a pheresis platelet concentrate unit is the eequivalent of 6 whole blood-expressed “random” platelet concentrate. The update is based on a series of publications arising first from data collected during the Iraq and Afghanistan wars and extending to the present.
Tranexamic acid seems to be a successful substitute or adjunt to 1:1:1 therapy, reducing the need for the standard components.
