BACKGROUND We endeavored to develop clinically translatable non-human primate (NHP) models of severe poly-traumatic hemorrhagic shock. METHODS NHPs were randomized into five pressure-targeted severe hemorrhagic shock (PTHS) ± additional injuries scenarios: 30-min PTHS (PTHS-30), 60-min PTHS (PTHS-60), PTHS-60 + soft tissue injury (PTHS-60+ST), PTHS-60+ST(More)
BACKGROUND Hypoperfusion is associated with hyperfibrinolysis and early death from exsanguination, whereas tissue trauma is associated with hypofibrinolysis and delayed death from organ failure. We sought to elucidate the effects of injury patterns on fibrinolysis phenotypes using a nonhuman primate (NHP) model. METHODS NHPs were randomized to three(More)
Hemorrhage is the leading cause of potentially survivable trauma mortality, necessitating the development of improved therapeutic interventions. The objective of this study was to develop and characterize a reproducible clinically translatable nonhuman primate model of uncontrolled severe hemorrhage. Such a model is required to facilitate the development(More)
BACKGROUND Hemorrhage remains the leading cause of potentially survivable trauma mortality. Recent reports indicate that injuries sustained in noncompressible anatomic locations (i.e., truncal and junctional) account for 86.5% of hemorrhage-related deaths. Infusible human platelet-derived hemostatic agents (hPDHAs) represent a promising strategy to reduce(More)
BACKGROUND Uncontrolled hemorrhage (UH), the leading cause of potentially survivable combat-related death, elicits a deleterious inflammatory response. Our group previously reported an increased secretion of pro-inflammatory cytokines in a novel non-human primate model of UH; however, to better understand the molecular profile of the inflammatory response(More)
BACKGROUND Heart rate (HR), systolic blood pressure (SBP) and mean arterial pressure (MAP) are traditionally used to guide patient triage and resuscitation; however, they correlate poorly to shock severity. Therefore, improved acute diagnostic capabilities are needed. Here, we correlated acute alterations in tissue oxygen saturation (StO2) and end-tidal(More)
