Introduction: Hemorrhage is the most common cause of death among Special Operations Force (SOF) soldiers. Bringing remote damage control resuscitation into the far-forward combat environment is logistically challenging, as it requires blood products that generally require a robust cold chain. Alternatively, lyophilized products such as fibrinogen concentrate, which does not require thawing or blood group compatibility testing before use, might be advantageous in damage control resuscitation in the battlefield...

In severe trauma and hemorrhage the early and empiric use of fresh frozen plasma (FFP) is associated with decreased morbidity and mortality. However, utilization of FFP comes with the significant burden of shipping and storage of frozen blood products. Dried or lyophilized plasma (LP) can be stored at room temperature, transported easily, reconstituted rapidly with ready availability in remote and austere environments. We have previously demonstrated that FFP mitigates the endothelial injury that ensues after hemorrhagic shock (HS)...

BACKGROUND: Early transfusion of high ratio of fresh frozen plasma (FFP) and red blood cells (RBC) is associated with mortality reduction. However, time to reach high ratio is limited by the need to thaw the FFP. French lyophilized plasma (FLYP) used by French army and available in military teaching hospital does not need to be thawed and is immediately available. We hypothesize that the use of FLYP may reduce time to reach a plasma:RBC ratio of 1/1. METHODS: A retrospective study performed in a Level 1 trauma center between January 2012 and December 2015...

Essentials An immediate supply of plasma in case of trauma-induced coagulopathy is required. The Traucc trial compared French Lyophilised Plasma (FLyP) and Fresh Frozen Plasma (FFP). FLyP achieved higher fibrinogen concentrations compared with FFP. FLyP led to a more rapid coagulopathy improvement than FFP. SUMMARY: Background Guidelines recommend beginning hemostatic resuscitation immediately in trauma patients. We aimed to investigate if French lyophilized plasma (FLyP) was more effective than fresh frozen plasma (FFP) for the initial management of trauma-induced coagulopathy...

Hemorrhage is the leading cause of preventable military and civilian trauma death. Damage control resuscitation with concomitant mechanical hemorrhage control has become the preferred in-hospital treatment of hemorrhagic shock. In particular, plasma-based resuscitation with decreased volumes of crystalloids and artificial colloids as part of damage control resuscitation has improved outcomes in the military and civilian sectors. However, translation of these principles and techniques to the prehospital, remote, and austere environments, known as remote damage control resuscitation, is challenging given the resource limitations in these settings...

Traumatic hemorrhage is the leading cause of preventable death after trauma. Early transfusion of plasma and balanced transfusion have been shown to optimize survival, mitigate the acute coagulopathy of trauma, and restore the endothelial glycocalyx. There are a myriad of plasma formulations available worldwide, including fresh frozen plasma, thawed plasma, liquid plasma, plasma frozen within 24 h, and lyophilized plasma (LP). Significant equipoise exists in the literature regarding the optimal plasma formulation...

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 blood loss from noncompressible injuries. Here, we evaluate the hemostatic efficacy of a lyophilized hPDHA in a rhesus macaque model of severe, uncontrolled hemorrhage...

Prothrombin complex concentrate (PCC) is a term to describe pharmacological products that contain lyophilized, human plasma-derived vitamin K-dependent factors (F), FII, FVII, FIX, FX, and various amounts of proteins C and S. PCCs can be rapidly reconstituted in a small volume (20 ml for about 500 international units (IU)) at bedside and administered regardless of the patient's blood type. PCCs are categorized as 4-factor PCC if they contain therapeutic amounts of FVII, and 3-factor PCC when FVII content is low...

OBJECTIVES: Blood transfusion is an aspect of medical care on the battlefield. French assets include: red blood cell units (RBCu), lyophilized plasma (PLYO), fresh whole blood (FWB) but neither fresh-frozen plasma (FFP) nor platelets. French transfusion strategy in military operations follows the evolution of knowledge and resources. We describe the characteristics of the transfusion at the military hospital in Kabul. PATIENTS AND METHODS: Retrospective study of records of patients transfused between October 2010 to December 2011 conducted in Kabul from transfusion register...

BACKGROUND: We performed this study to optimize reconstituted lyophilized plasma (LP) into a minimal volume fluid that provides effective hemostatic resuscitation for trauma while minimizing logistical limitations. METHODS: We performed a prospective, blinded animal study. Plasma was lyophilized following whole blood collection from anesthetized swine. The minimal volume needed for reconstitution was determined, and this solution was evaluated for safe infusion into the swine...

BACKGROUND: Transfusion of plasma is a basic treatment for complex coagulopathies as well as in major blood loss. Early transfusion of plasma after trauma with major hemorrhage has been recommended by retrospective studies. However, the use of plasma is often hampered by the need to maintain a cold chain and the time needed for thawing fresh-frozen plasma (FFP). With freeze-dried (lyophilized) plasma (FDP) both difficulties can be avoided. Here, we describe the production, quality characteristics, and our experiences with FDP...

PURPOSE OF REVIEW: Diagnosis and treatment of trauma-induced coagulopathy (TIC) presents a challenge for trauma care providers. Viscoelastic tests (VETs) including thromboelastometry and thrombelastography are increasingly used to diagnose TIC and guide hemostatic therapy. We summarize the concept of individualized, goal-directed coagulation management using coagulation factor concentrates. RECENT FINDINGS: Early and aggressive treatment is mandatory to improve the survival of severely bleeding trauma patients...

BACKGROUND: Shock and severe tissue injury lead to an endogenous coagulopathy mediated by activation of Protein C and hyperfibrinolysis known as acute traumatic coagulopathy. Together, hemodilution, acidosis, inflammation, and hypothermia result in a global trauma-induced coagulopathy. Coagulopathy in trauma is associated with mortality. Early and effective hemostatic resuscitation is critical in restoring perfusion, correcting coagulopathy, and saving lives in exsanguinating trauma. Lyophilized plasma (LP) provides a logistically superior alternative to fresh frozen plasma (FFP)...

BACKGROUND: Delivery of a high ratio of plasma to packed red blood cells to patients who require massive transfusion is associated with improved survival. Hemorrhagic shock causes increased production of pro-inflammatory cytokines. These are associated with late morbidity and mortality. The use of fresh frozen plasma makes high ratio resuscitation logistically difficult and does not address dysfunctional inflammation. Lyophilized plasma (LP) is a stable powdered form of plasma that is both safe and easily reconstituted...

BACKGROUND: Lyophilized plasma (LP) has been shown to be as effective as fresh frozen plasma (FFP) for resuscitation in polytrauma and hemorrhagic shock. LP reconstituted with ascorbic acid is associated with suppression of cytokines when compared with fresh frozen plasma. We aimed to determine the effect of using alternate LP reconstitution acids on physiologic parameters, blood loss, coagulation, oxidative DNA damage, and proinflammatory cytokines in a polytrauma and hemorrhagic shock model...

BACKGROUND: Trauma-associated coagulopathy carries an extremely high mortality. Fresh-frozen plasma (FFP) is the mainstay of treatment; however, its availability in the battlefield is limited. We have already shown that lyophilized, freeze-dried plasma (FDP) reconstituted in its original volume can reverse trauma-associated coagulopathy. To enhance the logistical advantage (lower volume and weight), we developed and tested a hyperoncotic, hyperosmotic spray-dried plasma (SDP) product in a multiple injuries/hemorrhagic shock swine model...

BACKGROUND: Hemorrhage and coagulopathy are major contributors to death after trauma. The contribution of red blood cells (RBCs) in correcting coagulopathy is poorly understood. Current methods of measuring coagulopathy may fail to accurately characterize in vivo clotting. We aimed to determine the effect of RBCs on clotting parameters by comparing resuscitation regimens containing RBCs and plasma with those containing plasma alone. METHODS: Thirty-two Yorkshire swine were anesthetized, subjected to a complex model of polytrauma and hemorrhagic shock, and resuscitated with either fresh frozen plasma, lyophilized plasma (LP), or 1:1 ratios of fresh frozen plasma:packed RBC (PRBC) or LP:PRBC...

HYPOTHESIS: Lyophilized plasma (LP) is as safe and effective as fresh frozen plasma (FFP) for resuscitation after severe trauma. DESIGN: Multicenter animal study. SETTING: Animal laboratories, 2 level I trauma centers. PARTICIPANTS: Thirty-two Yorkshire crossbred swine. INTERVENTIONS: Lyophilized plasma was analyzed for factor levels and clotting activity before lyophilization and after reconstitution...

BACKGROUND: Trauma-induced coagulopathy is associated with an extremely high mortality. We have recently shown that survival can be improved by correction of coagulopathy through early, aggressive infusion of Fresh Frozen Plasma (FFP). However, FFP is a perishable product, and its use is impractical in challenging environments such as a battlefield. Development of shelf-stable, easy to use, low volume, lyophilized, Freeze-Dried Plasma (FDP) can overcome the logistical limitations. We hereby report the development and testing of such a product...

This study was conducted to determine the possibility of detecting dangerous hypocoagulability in trauma victims given warfarin by measuring plasma activated clotting time (ACT). Sensitivity of the plasma ACT to warfarin was tested using lyophilized plasmas and plasma samples from nontraumatized but anticoagulated patients. Lyophilized plasmas were also used to evaluate the effect of defects in the intrinsic coagulation system on the plasma ACT. The plasma ACT, measured using a 4.4-mM calcium solution, showed satisfactory prolongation when the thrombotest of matched samples was within the therapeutic range for warfarin therapy...
