<h3>Importance</h3> Severely injured patients experiencing hemorrhagic shock often require massive transfusion. Earlier transfusion with higher blood product ratios (plasma, platelets, and red cells), defined as damage control resuscitation, has been associated improved outcomes; however, there have no large multicenter clinical trials. <h3>Objective</h3> To determine the effectiveness safety of transfusing severe trauma major bleeding using plasma, cells in a 1:1:1 ratio compared 1:1:2...

Background: The importance of early and aggressive management trauma- related coagulopathy remains poorly understood. We hypothesized that a trauma exsanguination protocol (TEP) systematically provides specified numbers types blood components immediately upon initiation resuscitation would improve survival reduce overall product consumption among the most severely injured patients. Methods: recently implemented TEP, which involves immediate continued release products from bank in predefined...

Background The resuscitation of severely injured bleeding patients has evolved into a multi-modal strategy termed damage control (DCR). This guideline evaluates several aspects DCR including the role massive transfusion (MT) protocols, optimal target ratio plasma (PLAS) and platelets (PLT) to red blood cells (RBC) during DCR, recombinant activated factor VII (rVIIa) tranexamic acid (TXA). Methods Using Grading Recommendations Assessment, Development Evaluation (GRADE) methodology,...

In Brief Objective: To determine whether implementation of damage control resuscitation (DCR) in patients undergoing laparotomy (DCL) translates into improved survival. Background: DCR aims at preventing coagulopathy through permissive hypotension, limiting crystalloids and delivering higher ratios plasma platelets. Previous work has focused only on the impact (1:1:1). Methods: A retrospective cohort study was performed all DCL admitted between January 2004 August 2010. Patients were divided...

Introduction: Massive transfusion (MT) protocols have been shown to improve survival in severely injured patients. However, others noted that these higher fresh frozen plasma (FFP):red blood cell (RBC) ratios are associated with increased risk of organ failure. The purpose this study was determine whether MT failure and complications. Methods: Our institution’s exsanguination protocol (TEP) involves the immediate delivery products a 3:2 ratio RBC:FFP 5:1 for RBC:platelets. All patients...

Injury and shock lead to alterations in conventional coagulation tests (CCTs). Recently, rapid thrombelastography (r-TEG) has become recognized as a comprehensive assessment of abnormalities. We have previously shown that admission r-TEG results are available faster than CCTs predict pulmonary embolism. hypothesized r-TEGs more reliably blood component transfusion CCTs.Consecutive patients admitted between September 2009 February 2011 who met the highest-level trauma activations were...

Despite recent attention and impressive results with damage control resuscitation, the appropriate ratio of blood products to be transfused has yet defined. The purpose this study was evaluate whether suggested product ratios yield superior survival rates.After IRB approval, a retrospective evaluation performed on all trauma exsanguination protocol (TEP, n = 118) activations from February 1, 2006 July 31, 2007. A comparison cohort (pre-TEP, 140) selected admissions between August 2004...

Prediction of massive transfusion (MT) among trauma patients is difficult in the early phase management. Whole-blood thromboelastometry (ROTEM®) tests provide immediate information about coagulation status acute bleeding patients. We investigated their value for prediction MT.This retrospective study included admitted to AUVA Trauma Centre, Salzburg, Austria, with an injury severity score ≥16, from whom blood samples were taken immediately upon admission emergency room (ER). ROTEM® analyses...

Hyperfibrinolysis (HF) has been reported to occur in a range of 2% 34% trauma patients. Using rapid thromboelastography (r-TEG), we hypothesized that HF is (1) rarely present at admission on patients with severe injury and (2) associated crystalloid hemodilution. To further strengthen this hypothesis, created an vitro hemodilution model improve our mechanistic understanding the early HF.The registry was queried for who were highest-level activations admitted directly from scene (October...

Background: Recognition of trauma-induced coagulopathy by conventional coagulation testing (CCT) is limited their slow results, incomplete characterization, and poor predictive nature. Rapid thrombelastography (r-TEG) delivers a more comprehensive assessment the system but has not been prospectively validated in trauma patients.

In Brief Objectives: To determine whether resuscitation of severely injured patients with modified whole blood (mWB) resulted in fewer overall transfusions compared component (COMP) therapy. Background: For decades, (WB) was the primary product for resuscitating hemorrhagic shock. After dramatic advances banking 1970s, donor centers began supplying hospitals individual components [red cell (RBC), plasma, platelets] and removed WB as an available product. However, no studies efficacy or...

Objective. Earlier use of plasma and red blood cells (RBCs) has been associated with improved survival in trauma patients substantial hemorrhage. We hypothesized that prehospital transfusion (PHT) thawed and/or RBCs would result patient coagulation status on admission survival. Methods. Adult records were reviewed for demographics, shock, coagulopathy, outcomes, product utilization from September 2011 to April 2013. Patients arrived by either ground or two different helicopter companies. All...
