Abstract

Background: Disruption of the vascular endothelium and endothelial glycocalyx (EG) has been described after severe trauma. Plasma has been suggested to restore microvascular integrity by preservation and repair of the EG. We sought to evaluate whether plasma administered in a 1:1:1 ratio was associated with less endothelial marker circulation than a 1:1:2 ratio.

Methods: This is a secondary analysis of the PROPPR trial, which investigated post-traumatic resuscitation with platelets, plasma, and red blood cells in a 1:1:1 ratio compared with a 1:1:2 ratio. Syndecan-1, soluble thrombomodulin (sTM), and receptor for advanced glycation end products (RAGE) were quantified for each treatment group on admission and at 2 hours, 4 hours, 6 hours, 12 hours, 24 hours, 48 hours, and 72 hours. Patients were excluded if they did not survive longer than 3 hours or had data from fewer than two time points.

Results: Three hundred eight patients in the 1:1:1 group and 291 in the 1:1:2 group were analyzed. There were no statistically significant differences in syndecan-1, sTM, or RAGE between treatment groups at any time point ( p > 0.05). Patients who developed acute respiratory distress syndrome, acute kidney injury, and death had significantly elevated biomarker expression at most time points when compared with patients who did not develop these sequelae ( p < 0.05).

Conclusion: Administration of FFP in a 1:1:1 ratio does not consistently affect circulation of endothelial biomarkers following significant trauma when compared with a 1:1:2 ratio. The development of post-traumatic ARDS, AKI, and death was associated with increased endothelial biomarker circulation.

Level of evidence: Therapeutic/Care Management; Level III.
