Fresh frozen plasma lessens pulmonary endothelial inflammation and hyperpermeability after hemorrhagic shock and is associated with loss of syndecan-1

BACKGROUND We have recently demonstrated that injured patients in hemorrhagic shock shed syndecan-1 and that the early use of fresh frozen plasma (FFP) in these patients is correlated with improved clinical outcomes. As the lungs are frequently injured after trauma, we hypothesized that hemorrhagic shock-induced shedding of syndecan-1 exposes the underlying pulmonary vascular endothelium to injury resulting in inflammation and hyperpermeability, and that these effects would be mitigated by FFP.
