Abstract
INTRODUCTION Gastrointestinal bleeding is a common life-threatening problem, causing significant mortality, costs and resource allocation. Its management requires a dynamic multidisciplinary approach that directs diagnostic and therapeutic priorities appropriately. MATERIALS AND METHODS Articles published within the past 15 years, related to gastrointestinal bleeding, were reviewed through MEDLINE search, in addition to current guidelines and standards. RESULTS Decisions of ICU admission and blood transfusion must be individualized based on the extent of bleeding, hemodynamic profile and comorbidities of the patient and the risk of rebleeding. A secure airway may be required to optimize oxygenation and to prevent aspiration. Doses of induction agents must be reduced due to the changes in volume of distribution. Volume replacement is the cornerstone of resuscitation in profuse bleeding, but nontargeted aggressive fluid resuscitation must be avoided to allow clot formation and to prevent increased bleeding. Decision to give blood transfusion must be based on physiologic triggers rather than a fixed level of hemoglobin. Coagulopathy must be corrected and hypothermia avoided. Need for massive transfusion must be recognized as early as possible, and a 1:1:1 ratio of packed red blood cells, fresh frozen plasma and platelets is recommended to prevent dilutional coagulopathy. Tromboelastography can be used to direct hemostatic resuscitation. Transfusion related lung injury (TRALI) is a significant problem with a mortality rate approaching 40%. Prevention of TRALI is important in patients with gastrointestinal bleeding, especially among patients having end-stage liver disease. Preventive strategies include prestorage leukoreduction, use of male-only or never-pregnant donors and avoidance of long storage times. Management of gastrointestinal bleeding requires delicately tailoring resuscitation to patient needs to avoid nonspecific aggressive resuscitation. "Functional hemodynamic monitoring" requires recognition of indications and limitations of hemodynamic measurements. Dynamic indices like systolic pressure variation are more reliable predictors of volume responsiveness. Noninvasive methods of hemodynamic monitoring and cardiac output measurement need further verification in patients with gastrointestinal bleeding. CONCLUSIONS Management of gastrointestinal bleeding requires a dynamic multidisciplinary approach. The mentioned advances in management of hemorrhagic shock must be considered in resuscitation and monitoring of patients with GI bleeding.

Abstract
SUMMARY: This report contains the data collected in 2008 and 2009, pursuant to Section 21 German Transfusion Act as well as an overview of the supply situation during the last 10 years. In 2009, blood donation services reported a total of 7.5 million donations - the largest amount since 2000. At the same time, more than 4.7 million red blood cell (RBC) concentrates and more than 500,000 platelet concentrates were available. The number of therapeutic single plasma units decreased to 1.1 million units in 2009. The loss rate for RBC concentrates is still between 3 and 4% for the users while for the manufacturers it has decreased slightly to 1.4%. The loss rate, for platelet concentrates, on the other hand, increased in 2009, especially-what is noteworthy-for manufacturers of pooled platelet concentrates. The loss rate for apheresis platelet concentrates accounted for 5.2% compared to 17.5% for pooled platelet concentrates. As far as the users were concerned, loss rates for platelet concentrates largely remained unchanged with rates between 5 and 6%. Based on the data collected, the supply with blood components for transfusion can be regarded as assured. Nearly 2.9 million 1 of plasma for fractionation were collected in Germany in 2009. According to reports from the pharmaceutical industry, out of these, 2.6 million 1 remained on the German market, out of which only 56% were fractionated in this country. Many plasma derivatives are not manufactured in Germany, despite the large amounts of plasma collected. The supply with these products, however, is assured by imports. Overall, 16,409 autologous and 9,435 allogeneic stem cell preparations were manufactured in 2009, out of which 3,382 allogeneic preparations were exported. 3,181 autologous and 2,374 allogeneic preparations were transplanted; 187 of these products from imports. The large number of exported stem cells and the small number of imported ones suggest that no serious shortages are to be expected for the supply with these products.

Abstract
PURPOSE Massive blood transfusios are uncommon. The goal of this study was to propose an ideal ratio for the blood component of massive hemorrhage treatment after review of five years of massive transfusion practice, in order to have the best possible clinical outcomes. MATERIALS AND METHODS We defined a 'massive transfusion' as receiving 10 or more units of red blood cells in one day. A list of patients receiving a massive transfusion from 2004 to 2008 was generated using the electronic medical records. For each case, we calculated the ratio of blood components and examined its relationship to their survival. RESULTS Three hundred thirty four patients underwent massive transfusion during the five years of the study. The overall seven-day hospital mortality for massive transfusion patients was 26.1%. Factors independently predictive of survival were a fresh-frozen plasma (FFP)/packed red blood cell (pRBC) ratio ≥ 1.1 with an odds ratio (OR) of 1.96 (1.03-3.70), and elective admission with an OR of 2.6 (1.52-4.40). The receiver operation characteristic (ROC) curve suggest that a 1 : 1 : 1 ratio of pRBCs to FFP to platelets is the best ratio for survival. CONCLUSION Fixing blood-component ratios during active hemorrhage shows improved outcomes. Thus, the hospital blood bank and physician hypothesized that a fixed blood component ratio would help to reduce mortality and decrease utilization of the overall blood component.

Abstract
BACKGROUND AND OBJECTIVES Primary resuscitation for massive haemorrhage often occurs in emergency departments or operating theatres, with ongoing resuscitation in the intensive care unit (ICU). The aim of the study was to retrospectively review transfusion practice in the pre-ICU phase and ICU for patients with massive haemorrhage. MATERIALS AND METHODS From 1998 to 2006, we developed an electronically linked database of blood and blood product usage and laboratory data with clinical outcome. All patients who received 10 or more units of red cells and required ICU admission were included. RESULTS Of 238 patients who required massive transfusion, 40 died early (within 24 h of massive transfusion), out of which 16 died in pre-ICU and 24 died in ICU. Comparatively this group of patients presented in the pre-ICU phase and on ICU admission, respectively, with coagulopathy (median international normalized ratio 1.6 and 2.1) and acidosis (median base deficit -11.5 and -14 mmol/l). These patients had median ratios of fresh frozen plasma (FFP) to red blood cells of 1:3.3 and 1:1.3 in the pre-ICU and ICU phases, respectively. Severity of coagulopathy indicated by INR at ICU admission [P = 0.04; area under receiver operator curve (ROC) = 0.69] and RBC transfused (P = 0.01) in 24 h associated with mortality. CONCLUSIONS Patients who died early were coagulopathic before and on ICU admission and did not correct their coagulopathy. This study also shows that coagulopathy is associated with an increased risk of mortality. Early and aggressive correction of coagulopathy for patients presenting with coagulopathy may be effective in improving mortality.

Abstract
Developments in the resuscitation of the severely injured trauma patient in the last decade have been through the increased understanding of the early pathophysiological consequences of injury together with some observations and experiences of recent casualties of conflict. In particular, the recognition of early derangements of haemostasis with hypocoagulopathy being associated with increased mortality and morbidity and the prime importance of tissue hypoperfusion as a central driver to this process in this population of patients has led to new resuscitation strategies. These strategies have focused on haemostatic resuscitation and the development of the ideas of damage control resuscitation and damage control surgery continuum. This in turn has led to a requirement to be able to more closely monitor the physiological status, of major trauma patients, including their coagulation status, and react in an anticipatory fashion.

Abstract
BACKGROUND AND OBJECTIVES The empiric use of a high plasma to packed red-blood-cell [fresh frozen plasma:red-blood-cells (FFP:RBC)] ratio in trauma resuscitation for patients with massive bleeding has become well accepted without clear or objective indications. Increased plasma transfusion is associated with worse outcome in some patient populations. While previous studies analyse only patients who received a massive transfusion, this study analyses those that are at risk to receive a massive transfusion, based on the trauma-associated severe haemorrhage (TASH) score, to objectively determine which patients after severe trauma would benefit or have increased complications by the use of a high FFP:RBC ratio. METHODS Multicentre retrospective study from the Trauma Registry of the German Trauma Society. Multivariate logistic regression and statistical risk adjustments utilized in analyses. RESULTS A high ratio of FFP:RBC in the ≥15 TASH group was independently associated with survival, with an odds ratio of 2·5 (1·6-4·0), while the <15 TASH group was associated with increased multi-organ failure, 47% vs. 38%, (P<0·005). CONCLUSIONS A predictive model of massive transfusion upon admission might be able to rapidly identify which severe trauma patients would benefit or have increased complications from the immediate application of a high ratio of FFP:RBCs. This study helps to identify the appropriate population for a prospective, interventional trial.

Abstract
Systematic reviews are accepted as a robust and less biased means of appraising and synthesizing results from high-quality studies. This report collated and summarized all the systematic review evidence relating to the diagnosis and management of trauma-related coagulopathy and transfusion, thereby covering the widest possible body of literature. We defined 4 key clinical questions: (1) What are the best methods of predicting and diagnosing trauma-related coagulopathy? (2) Which methods of clinical management correct coagulopathy? (3) Which methods of clinical management correct bleeding? and (4) What are the outcomes of transfusion in trauma? Thirty-seven systematic reviews were identified through searches of MEDLINE (1950-July 2010), EMBASE (1980-July 2010), The Cochrane Library (Issue 7, 2010), National Guidelines Clearing House, National Library for Health Guidelines Finder, and UKBTS SRI Transfusion Evidence Library (www.transfusionevidencelibrary.com). The evidence from the systematic review literature was scanty with many gaps, and we were not able to conclusively answer any of our 4 questions. Much more needs to be understood about how coagulopathy and bleeding in trauma are altered by transfusion practices and, most importantly, whether this translates into improved survival. There is a need for randomized controlled trials to answer these questions. The approach described in this report provides a framework for incorporating new evidence.

Abstract
BACKGROUND Resuscitation of rapidly bleeding trauma patients with units of red blood cells (RBCs) and plasma given in a 1:1 ratio has been associated with improved outcome. However, demonstration of a benefit is confounded by survivor bias, and past work from our group has been unable to demonstrate a benefit. STUDY DESIGN AND METHODS We identified 438 adult direct primary trauma admissions at risk for massive transfusion who received 5 or more RBC units in the first 24 hours and had a probability of survival of 0.010 to 0.975. We correlated survival with RBC and plasma use by hour, both as a ratio (units of plasma/units of RBC) and as a plasma deficit (units of RBC - units of plasma) in the group as a whole and among those using 5 to 9 and more than 9 units of RBCs. RESULTS Resuscitation was essentially complete in 58.3% by the end of the third hour and 77.9% by the end of the sixth hour. Mortality by hour was significantly associated with worse plasma deficit status in the first 2 hours of resuscitation (p < 0.001 and p < 0.01) but not with plasma ratio. In a subgroup with a Trauma Revised Injury Severity Score of 0.200 to 0.800, early plasma repletion was associated with less blood product use independently of injury severity (p < 0.001). CONCLUSIONS 1) The efficacy of plasma repletion plays out in the first few hours of resuscitation, 2) plasma deficit may be a more sensitive marker of efficacy in some populations, and 3) early plasma repletion appears to prevent some patients from going on to require massive transfusion.

Abstract
PURPOSE The management of trauma patients suffering from active bleeding has improved with a better understanding of trauma-induced coagulopathy. The aim of this manuscript is to give recommendations for coagulation management. METHODS A systematic literature search in the PubMed database was performed for articles published between January 2000 and August 2009. A total of 230 articles were included in the present systematic review. CONCLUSIONS The "coagulopathy of trauma" is a discrete disease which has a decisive influence on survival. Diagnosis and therapy of deranged coagulation should start immediately after admission to the emergency department. A specific protocol for massive transfusion should be introduced and continued. Loss of body temperature should be prevented and treated. Acidaemia should be prevented and treated by appropriate shock therapy. If massive transfusion is performed using fresh frozen plasma (FFP), a ratio of FFP to pRBC (packed red blood cells) of 1:2-1:1 should be achieved. Fibrinogen should be substituted at levels of <1.5 g/L. For patients suffering from active bleeding, permissive hypotension (i.e. mean arterial pressure ~65 mmHg) may be aimed for until surgical cessation of bleeding. This option is contraindicated in injuries of the central nervous system and in patients with coronary heart disease, or with known hypertension. Thrombelastography or -metry may be performed to guide coagulation diagnosis and substitution. Hypocalcaemia <0.9 mmol/L should be avoided and may be treated. For actively bleeding patients, pRBC may be given at haemoglobin <10 g/L (6.2 mmol/L) and haematocrit may be targeted at 30%.

Abstract
Early recognition and differentiation of shock, as well as goal-directed resuscitation, are fundamental principles in the care of the critically ill or injured patient. Substantial progress has been made over the last decade in the understanding of both shock and resuscitation. Specific areas of advancement, particularly pertaining to hemorrhagic shock, include a heightened appreciation of dynamic measurements of preload responsiveness (e.g., respiratory-induced pulse pressure and venous diameter variability), an improved awareness of the detrimental effects of blood product transfusion, and better recognition of the complications of overzealous volume expansion. However, several areas of controversy remain regarding the optimal resuscitation strategy. These include the optimal targets for perfusion pressure and oxygen delivery, endpoints of resuscitation, resuscitative fluid, and transfusion strategies for packed red blood cells and blood products. This article reviews the diagnosis and differentiation of shock, measurements of tissue perfusion, current evidence regarding various resuscitative techniques, and complications of resuscitation.

Abstract
Damage control surgery emphasizes limited operations with control of bleeding and contamination. Traditional management centered upon correction of acidosis and hypotension with crystalloids. Damage control resuscitation (DCR) is permissive hypotension and early hemostatic resuscitation combined identified and corrects coagulopathy with fresh-frozen plasma (FFP), restricting use of crystalloids. We hypothesize a survival advantage in patients managed with DCR when compared with a historical cohort of patients. During the 2-year retrospective review, a 1-year period after institution of DCR was compared with a historical control. Resuscitation strategies were analyzed and stratified into emergency department (ED) resuscitation and intraoperative resuscitation. Univariate analysis of continuous data was done with Student's t test followed by multiple logistic regression. Fifty-seven and 61 patients were managed during the Non DCR and DCR periods respectively. Baseline demographic patient characteristics and physiologic variables were similar between groups. ED DCR patients received less crystalloids: 1.1 versus 4.7 liters ( P = 0.0001), more FFP: 1.8 versus 0.5 ( P = 0.001). NonDCR had a lower initial systolic pressure in the operating room when compared with DCR: 81 mm Hg versus 95 mm Hg ( P = 0.03). DCR patients received less intraoperative crystalloids: 5.7 versus 15.8 liters ( P = 0.0001) and more FFP: 15.1 versus 6.2 ( P = 0.0001). DCR conveyed a survival benefit (Odds Ratio; 95% confidence interval: 0.40 (0.18-0.90), P = 0.024). NonDCR group had 13.2 days longer hospital length of stay. Damage control resuscitation, beginning in the ED, used more packed red blood cells and FFP minimizing crystalloids. DCR was associated with a survival advantage and shorter length of stay in patients with severe hemorrhage.

Abstract
The collaboration of blood transfusion service in the management of severely combat-injured individuals has proved to be an essential factor for the successful treatment of these patients. While the operating and anesthesiology teams are engaged in maintaining the vital signs and controlling blood loss of the injured, the transfusion service representatives follow the information on the amount of blood products given and the latest laboratory tests, as well as provide consultations regarding further blood component requirements on the basis of data obtained. A major effort of the treating team should be aimed at diagnosis and correction of coagulopathy, acidosis, and hypothermia. For the massively bleeding combat trauma injured, which can amount to as high as 8% of all trauma patients, a generous use of plasma at a one-to-one ratio with packed cells, along with the early addition of platelets and cryoprecipitates, should be considered. Early point-of-care thromboelastography is helpful for identification of coagulopathies. The use of a preset massive transfusion protocol is beneficial; however, it should be tailored according to the patient’s actual needs, depending on the type of injury and the individual’s general condition.

The outcomes of interest included immediate postoperative coagulation laboratory test results, postoperative surgical drain output, and the number of unique blood donor exposures incurred. BACKGROUND We recently changed our intraoperative transfusion strategy in children undergoing craniofacial reconstruction surgery to one in which blood loss is replaced with donor-matched reconstituted blood rather than traditional blood component therapy. METHODS We performed a query of our prospective craniofacial surgery perioperative registry for children who underwent fronto-orbital advancement or posterior cranial vault reconstruction. Registry data from this query were compared to data from a historical cohort. RESULTS Data for 46 registry cases were compared to 150 historical cohort cases. The median number of unique donor exposures for the reconstituted blood group was 2 vs 3 in the historical cohort (P=0.004). The reconstituted blood group had a decreased incidence of postoperative derangements in soluble clotting factor tests (fibrinogen, PT, or aPTT; 2% vs 24%, P=0.001), while there was no evidence for a difference in the incidence of thrombocytopenia. There was no evidence for differences in postoperative surgical drain output in the reconstituted blood group and historical cohort over the first 12, 24, and 48 h. CONCLUSIONS Prophylactic administration of FFP in the form of donor-matched reconstituted blood in children undergoing craniofacial reconstruction was associated with improved postoperative coagulation parameters, reduced blood donor exposures, and unchanged postoperative surgical drain output.

Abstract
Severe tissue trauma is frequently associated with hemorrhagic shock and subsequent pronounced coagulopathy [1]. Uncontrolled bleeding is the second most common cause of death, and hemorrhage is directly responsible for 40 % of all trauma-related deaths [2]. Coagulopathy can be detected with standard coagulation tests immediately after arrival in the emergency room (ER) in approximately 25–35 % of all trauma patients [1], [2]. Moreover, early trauma-induced coagulopathy is associated with a 4-fold increase in mortality [1]. Blood coagulation monitoring is essential in order to assess the underlying coagulation disorder and to tailor hemostatic treatment. Thromboelastometry (TEM) and thrombelastography (TEG) are promising point-of-care technologies providing rapid information on the initiation process of clot formation, clot quality, and stability of the clot [3].

Abstract
BACKGROUND The purpose of this study was to evaluate the ability of uncrossmatched transfusions in the emergency department (ED) to predict early (< 6 hr) massive transfusion (MT) of red blood cells (RBCs) and blood components. STUDY DESIGN AND METHODS All patients admitted to a Level 1 trauma center between July 2005 and June 2007 who received any transfusions and were transported directly from the scene of injury were included. Early MT was defined as the need for 10 U or more or RBCs in the first 6 hours. Early MT plasma was defined as 6 U or more of plasma in the first 6 hours. Early MT platelets (PLTs) were defined as two or more apheresis transfusions in the first 6 hours. Univariate and multivariate analyses were performed. RESULTS A total of 485 patients (34%) received ED transfusions (ED RBC+) and 956 (66%) did not receive ED transfusions (ED RBC-). ED RBC+ patients were younger, were more likely to be male, and arrived with more severe injuries. Multivariate regression identified ED transfusion of uncrossmatched RBC as an independent predictor of requiring early MT of RBCs (odds ratio [OR], 3.5; 95% confidence interval [CI], 1.36-7.59; p = 0.001), plasma (OR, 2.7; 95% CI, 1.66-4.39; p < 0.001), and PLTs (OR, 1.9; 95% CI, 1.08-3.41; p = 0.025). CONCLUSION Patients receiving uncrossmatched RBCs in the ED are more than three times more likely to receive early MT of RBCs. Additionally, patients transfused with ED RBCs are more likely to receive 6 units or more of plasma and two or more apheresis PLT transfusions. Given these findings, ED transfusion of uncrossmatched RBCs should be considered a potential trigger for activation of an institution's MT protocol.

Abstract
The understanding of post injury multiple organ failure (MOF) has evolved considerably since it was first described more than 30 years ago. Improved trauma care has decreased the mortality of single organ injury, although these patients may go on to MOF. There has been significant investigation in both the basic science and clinical understanding of MOF. This research has altered management strategies thereby decreasing the incidence and mortality related to MOF. Despite this MOF remains the greatest contributor to late trauma death and morbidity. This review defines essential terminology, examines the historical perspective of MOF, describes common scoring systems, describes the changes in epidemiology, discusses the aetiology and pathophysiology, reviews current prevention, resuscitation and treatment strategies and provides future direction for research.

Abstract
Hemorrhagic shock in the pediatric trauma patient is an uncommon but fundamental problem for the treating clinician. Current management of hemorrhagic shock involves initial resuscitation with crystalloid fluids followed by infusion of blood components as necessary. In management of the adult trauma patient, many institutions have implemented massive transfusion protocols to guide transfusion in situations requiring or anticipating the use of greater than 10 U of packed red blood cells. In the pediatric population, guidelines for massive transfusion are vague or nonexistent. Adult trauma transfusion protocols can be applied to children until a pediatric protocol is validated. Here, we attempt to identify certain principles of transfusion therapy specific to pediatric trauma and outline a sample pediatric massive transfusion protocol that may be used to guide resuscitation. Also, adjuncts to transfusion, such as colloid fluids, other plasma expanders or hemoglobin substitutes, and recombinant activated factor VII, are discussed.

Abstract
BACKGROUND Clinical studies have shown that resuscitation with fresh frozen plasma (FFP) is associated with improved outcome after severe hemorrhagic shock (HS). We hypothesized that in addition to its effects on hemostasis, FFP has protective and stabilizing effects on the endothelium that translate into diminished endothelial cell (EC) permeability and improved resuscitation in vivo after HS. We further hypothesized that the beneficial effects of FFP would diminish over 5 days of routine storage at 4 degrees C. METHODS EC permeability was induced by hypoxia and assessed by the passage of 70-kDa Dextran between monolayers. Thrombin generation time and coagulation factor levels or activity were assessed in FFP. An in vivo rat model of HS and resuscitation was used to determine the effects of FFP on hemodynamic stability. RESULTS Thawed FFP inhibits EC permeability in vitro by 10.2-fold. Protective effects diminish (to 2.5-fold) by day 5. Thrombin generation time is increased in plasma that has been stored between days 0 and 5. In vivo data show that day 0 FFP is superior to day 5 FFP in maintaining mean arterial pressure in rats undergoing HS with resuscitation. CONCLUSION Both in vitro and in vivo studies show that FFP has beneficial effects on endothelial permeability, vascular stability, and resuscitation in rats after HS. The benefits are independent of hemostasis and diminish between days 0 and 5 of storage.

Abstract
The majority of trauma patients (>90%) do not require any blood product transfusion and their mortality is <1%. However, 3% to 5% of civilian trauma patients will receive a massive transfusion (MT), defined as >10 units of packed red blood cells (PRBC) in 24 hours. In addition, more than 25% of these patients will arrive to emergency departments with evidence of trauma-associated coagulopathy. With this combination of massive blood loss and coagulopathy, it has become increasingly more common to transfuse early the trauma patients and with a combination of PRBC, plasma, and platelets. Given the inherent uncertainties common early in the care of patients with severe injuries, the efficient administration of massive amounts of PRBC and clotting factors tends to work best in a predefined, protocol driven system. Our purpose here is to (1) define the problem of massive hemorrhage and coagulopathy in the trauma patient, (2) identify which group of patients this type of protocol should be applied, (3) describe the extensive coordination required to implement this multispecialty MT protocol, (4) explain in detail how the MT was developed and implemented, and (5) emphasize the need for a robust performance improvement or quality improvement process to monitor the implementation of such a protocol and to help identify problems and deliver feedback in a "real-time" fashion. The successful implementation of such a complex process can only be accomplished in a multispecialty setting. Input and representation from departments of Trauma, Critical Care, Anesthesiology, Transfusion Medicine, and Emergency Medicine are necessary to successfully formulate (and implement) such a protocol. Once a protocol has been agreed upon, education of the entire nursing and physician staff is equally essential to the success of this effort. Once implemented, this process may lead to improved clinical outcomes and decreased overall blood utilization with extremely small wastage of vital blood products.

Abstract
PURPOSE OF REVIEW Trauma patients requiring massive transfusion represent a population at high risk for potentially preventable death. This review describes recent advances in the early recognition and treatment of the coagulopathy of trauma, as well as ongoing work to define optimal resuscitation strategies. RECENT FINDINGS Damage control resuscitation involves the rapid correction of hypothermia and acidosis, direct treatment of coagulopathy, and early transfusion in trauma patients. Recent evidence demonstrates improved mortality and lower overall blood product usage with higher ratios of plasma and platelets to red blood cells transfused. Adjuncts to damage control resuscitation such as factor VIIa may also be beneficial. Thrombelastography and advances in point-of-care testing may provide timely measurements to help guide massive transfusion in patients based on their individual needs. SUMMARY As optimal resuscitation strategies continue to evolve, recent efforts have focused on early and aggressive treatment of coagulopathy, with higher ratios of plasma and platelets to red blood cells transfused. Early evidence suggests that such strategies have a beneficial outcome in regards to trauma-related mortality.

Abstract
Trauma is the third leading cause of death in the U.S. Timely acute care anesthetic management of patients following traumatic injury may improve outcome. Recognition of highly-mortal injuries to the brain, heart, lungs, liver, and pelvis should guide trauma-specific management strategies. Rapid intraoperative treatment of life-threatening conditions following injury includes the use of 'controlled-under resuscitation' of fluid administration until surgical hemorrhage control, early factor replacement in addition to transfusion of packed red blood cells, and use of adjuvant therapies such as recombinant factor VIIa. These treatment strategies, other recent developments in acute trauma resuscitation, and a review of associated co-existing medical conditions that may impact mortality, are presented.

Abstract
During trauma resuscitation involving massive transfusion, the best fresh-frozen plasma to packed red blood cells ratio is unknown. No randomised controlled trial (RCT) is available on this subject, although there are plenty of observational studies suggesting that the ratio should be about 1:1. This ratio also makes more physiological sense, and we suggest that in patients with massive and ongoing bleeding, it is a sensible strategy with which to start resuscitation.

Abstract
Clinical studies support the use of perioperative fresh frozen plasma (FFP) in patients who are actively bleeding with multiple coagulation factor deficiencies and for the prevention of dilutional coagulopathy in patients with major trauma and/or massive haemorrhage. In these settings, current FFP dosing recommendations may be inadequate. However, a substantial proportion of FFP is transfused in non-bleeding patients with mild elevations in coagulation screening tests. This practice is not supported by the literature, is unlikely to be of benefit and unnecessarily exposes patients to the risks of FFP. The role of FFP in reversing the effects of warfarin anticoagulation is dependent on the clinical context and availability of alternative agents. Although FFP is commonly transfused in patients with liver disease, this practice needs broad reconsideration. Adverse effects of FFP include febrile and allergic reactions, transfusion-associated circulatory overload and transfusion-related acute lung injury. The latter is the most serious complication, being less common with the preferential use of non-alloimmunised, male-donor predominant plasma. FP24 and thawed plasma are alternatives to FFP with similar indications for administration. Both provide an opportunity for increasing the safe plasma donor pool. Although prothrombin complex concentrates and factor VIIa may be used as alternatives to FFP in a variety of specific clinical contexts, additional study is needed.

Abstract
Progressive postinjury coagulopathy remains the fundamental rationale for damage control surgery, but the decision to abort operative intervention must occur before laboratory confirmation of coagulopathy. Current massive transfusion protocols have embraced pre-emptive resuscitation strategies emphasizing administration of packed red blood cells, fresh frozen plasma, and platelets in ratios approximating 1:1:1 during the first 24 hours postinjury, based on US military retrospective experience and recent noncontrolled civilian data. This policy, termed "damage control resuscitation" assumes that patients presenting with life threatening hemorrhage at risk for postinjury coagulopathy should receive component therapy in rations approximating those found in whole blood during the first 24 hours. While we concur with the concept of pre-emptive coagulation factor replacement, and initially suggested this in 1982, we remain concerned for the continued unbridled administration of fresh frozen plasma and platelets without objective evidence of their specific requirement. A major limitation of current massive transfusion protocols is the lack of real time assessment of coagulation function to guide evolving blood component requirements. Existing laboratory coagulation testing was originally designed for evaluation of hemophilia and subsequently used for monitoring anticoagulation therapy. Consequently, the applicability of these tests in the trauma setting has never been proven and the time required to conduct these assays is incompatible with prompt correction of the coagulopathy in the trauma setting. This review examines the current approach to postinjury coagulopathy, including identification of patients at risk, resuscitation strategies, design and implementation of institutional massive transfusion protocols, and the potential benefits of goal-directed therapy by real time assessment of coagulation function via point of care rapid thromboelastography.

Abstract
BACKGROUND For trauma patients requiring massive blood transfusion, aggressive plasma usage has been demonstrated to confer a survival advantage. The aim of this study was to evaluate the impact of plasma administration in nonmassively transfused patients. STUDY DESIGN Trauma patients admitted to a Level I trauma center (2000-2005) requiring a nonmassive transfusion (<10 U packed RBC [PRBC] within 12 hours of admission) were identified retrospectively. Propensity scores were calculated to match and compare patients receiving plasma in the first 12 hours with those who did not. RESULTS The 1,716 patients (86.1% of 1,933 who received PRBC transfusion) received a nonmassive transfusion. After exclusion of 31 (1.8%) early deaths, 284 patients receiving plasma were matched to patients who did not. There was no improvement in survival with plasma transfusion (17.3% versus 14.1%; p = 0.30) irrespective of the plasma-to-PRBC ratio achieved. However, the overall complication rate was significantly higher for patients receiving plasma (26.8% versus 18.3%, odds ratio [OR] = 1.7; 95% CI, 1.1-2.4; p = 0.016). As the volume of plasma increased, an increase in complications was seen, reaching 37.5% for patients receiving >6 U. The ARDS rate specifically was also significantly higher in patients receiving plasma (9.9% versus 3.5%, OR = 3.0; 95% CI, 1.4-6.2; p = 0.004]. Patients receiving >6 U plasma had a 12-fold increase in ARDS, a 6-fold increase in multiple organ dysfunction syndrome, and a 4-fold increase in pneumonia and sepsis. CONCLUSIONS For nonmassively transfused trauma patients, plasma administration was associated with a substantial increase in complications, in particular ARDS, with no improvement in survival. An increase in multiple organ dysfunction, pneumonia, and sepsis was likewise seen as increasing volumes of plasma were transfused. The optimal trigger for initiation of a protocol for aggressive plasma infusion warrants prospective evaluation.

Abstract
Introduction The appropriate strategy for trauma-induced coagulopathy management is under debate. We report the treatment of major trauma using mainly coagulation factor concentrates. Methods This retrospective analysis included trauma patients who received ≥ 5 units of red blood cell concentrate within 24 hours. Coagulation management was guided by thromboelastometry (ROTEM®). Fibrinogen concentrate was given as first-line haemostatic therapy when maximum clot firmness (MCF) measured by FibTEM (fibrin-based test) was <10 mm. Prothrombin complex concentrate (PCC) was given in case of recent coumarin intake or clotting time measured by extrinsic activation test (EXTEM) >1.5 times normal. Lack of improvement in EXTEM MCF after fibrinogen concentrate administration was an indication for platelet concentrate. The observed mortality was compared with the mortality predicted by the trauma injury severity score (TRISS) and by the revised injury severity classification (RISC) score. Results Of 131 patients included, 128 received fibrinogen concentrate as first-line therapy, 98 additionally received PCC, while 3 patients with recent coumarin intake received only PCC. Twelve patients received FFP and 29 received platelet concentrate. The observed mortality was 24.4%, lower than the TRISS mortality of 33.7% (P = 0.032) and the RISC mortality of 28.7% (P > 0.05). After excluding 17 patients with traumatic brain injury, the difference in mortality was 14% observed versus 27.8% predicted by TRISS (P = 0.0018) and 24.3% predicted by RISC (P = 0.014). Conclusions ROTEM®-guided haemostatic therapy, with fibrinogen concentrate as first-line haemostatic therapy and additional PCC, was goal-directed and fast. A favourable survival rate was observed. Prospective, randomized trials to investigate this therapeutic alternative further appear warranted.

METHODS Records of all patients who underwent craniofacial surgery at the Children's Hospital of Philadelphia between December 1, 2001 and January 1, 2006 were reviewed. Data were collected from the electronic anesthesia record, intensive care unit (ICU) progress notes, and discharge summary. All intraoperative laboratory values and all laboratory values obtained upon arrival in the ICU were recorded. A multivariable analysis was performed to evaluate associations between elements of intraoperative management and the following clinical outcomes: intraoperative hypotension, intraoperative metabolic acidosis, presence of a postoperative coagulation test abnormality, and postoperative administration of hemostatic blood products. RESULTS Data for 159 patients were reviewed. The mean volume of packed red blood cells transfused intraoperatively was 51 ml x kg(-1). Multivariable analysis revealed that intraoperative administration of albumin was strongly correlated with both an increased incidence of postoperative coagulation derangements and postoperative administration of hemostatic blood products (Odds Ratio 5.9, 2.8, respectively), while intraoperative fresh frozen plasma (FFP) administration was associated with an opposite effect (Odds Ratio 0.94, 0.97, respectively). CONCLUSIONS In pediatric CFR procedures where the volume of blood loss routinely exceeds one blood volume, intraoperative administration of FFP favorably impacted postoperative laboratory coagulation parameters.

Abstract
OBJECTIVES While hospital length of stay (LOS) has been used as a surrogate injury outcome when more detailed outcomes are unavailable, it has not been validated. This project sought to validate LOS as a proxy measure of injury severity and resource use in heterogeneous injury populations. METHODS This observational study used four retrospective cohorts: patients presenting to 339 California emergency departments (EDs) with a primary International Classification of Diseases, Ninth Revision (ICD-9), injury diagnosis (years 2005-2006); California hospital injury admissions (a subset of the ED population); trauma patients presenting to 48 Oregon EDs (years 1998-2003); and injured Medicare patients admitted to 171 Oregon and Washington hospitals (years 2001-2002). In-hospital deaths were excluded, as they represent adverse outcomes regardless of LOS. Duration of hospital stay was defined as the number of days from ED admission to hospital discharge. The primary composite outcome (dichotomous) was serious injury (Injury Severity Score [ISS] >or= 16 or ICD-9 ISS <or= 0.90) or resource use (major surgery, blood transfusion, or prolonged ventilation). The discriminatory accuracy of LOS for identifying the composite outcome was evaluated using receiver operating characteristic (ROC) analysis. Analyses were also stratified by age (0-14, 15-64, and >or=65 years), hospital type, and hospital annual admission volume. RESULTS The four cohorts included 3,989,409 California ED injury visits (including admissions), 236,639 California injury admissions, 23,817 Oregon trauma patients, and 30,804 Medicare injury admissions. Composite outcome rates for the four cohorts were 2.1%, 29%, 27%, and 22%, respectively. Areas under the ROC curves for overall LOS were 0.88 (California ED), 0.74 (California admissions), 0.82 (Oregon trauma patients), and 0.68 (Medicare patients). In general, the discriminatory value of LOS was highest among children, tertiary trauma centers, and higher volume hospitals, although this finding differed by the injury population and outcome assessed. CONCLUSIONS Hospital LOS may be a reasonable proxy for serious injury and resource use among injury survivors when more detailed outcomes are unavailable, although the discriminatory value differs by age and the injury population being studied.

Abstract
PURPOSE OF REVIEW Care of the injured patient is a dynamic process. Hemorrhage remains the primary cause of preventable death after trauma. Rapid and effective early care can improve survival and outcomes. Emerging therapies to address traumatic hemorrhage will be discussed. RECENT FINDINGS Current concepts in trauma care include damage control resuscitation with rapid surgical correction of bleeding; prevention of the development of the lethal triad; limitation of crystalloid administration and application of high ratios of plasma and platelets to packed red blood cells. Prehospital resuscitation strategies can effect care of the hemorrhaging trauma patient, as well. The goal should be to preserve vital functions without increasing the risk for further bleeding. The concept of hypotensive resuscitation has been formulated to address this issue. The type of resuscitation fluid also plays an important role, with novel fluids currently being studied for routine use. Compressible hemorrhage constitutes an important component of potentially survivable injury. Hemostatic dressings and tourniquets can prove essential to the management of combat and civilian wounds. SUMMARY Given the potential to preserve life with appropriate attention applied to the bleeding trauma victim, it is vitally important to explore the options currently available and continue to make improvements in care.

Abstract
Fresh frozen plasma (FFP) is indicated for the management of massive bleedings. Recent audits suggest physician knowledge of FFP is inadequate and half of the FFP transfused in critical care is inappropriate. Trauma is among the largest consumers of FFP. Current trauma resuscitation guidelines recommend FFP to correct coagulopathy only after diagnosed by laboratory tests, often when overt dilutional coagulopathy already exists. The evidence supporting these guidelines is limited and bleeding remains a major cause of trauma-related death. Recent studies demonstrated that coagulopathy occurs early in trauma. A novel early formula-driven haemostatic resuscitation proposes addressing coagulopathy early in massive bleedings with FFP at a near 1:1 ratio with red blood cells. Recent retrospective reports suggest such strategy significantly reduces mortality, and its use is gradually expanding to nontraumatic bleedings in critical care. The supporting studies, however, have bias limiting the interpretation of the results. Furthermore, logistical considerations including need for immediately available universal donor AB plasma, short life after thawing, potential waste and transfusion-associated complications have challenged its implementation. The present review focuses on FFP transfusion in massive bleeding and critically appraises the evidence on formula-driven resuscitation, providing resources to allow clinicians to develop informed opinion, given the current deficient and conflicting evidence.

Abstract
PURPOSE OF REVIEW Bleeding and death from hemorrhage remain a leading cause of morbidity and mortality in the trauma population. Early resuscitation of these gravely injured patients has changed significantly over the past several years. The concept of damage control resuscitation has expanded significantly with the experience of the US military in southwest Asia. This review will focus on this resuscitation strategy of transfusing blood products (red cells, plasma, and platelets) early and often in the exsanguinating patient. RECENT FINDINGS In trauma there are no randomized controlled trials comparing the current damage control hematology concept to more traditional resuscitation methods. But the overwhelming conclusion of the data available support the administration of a high ratio of plasma and platelets to packed red blood cells. Several large retrospective studies have shown ratios close to 1: 1 will result in higher survival. SUMMARY The current evidence supports that the acute coagulopathy of trauma is present in a high percentage of trauma patients. Patients who will require a massive transfusion will have improved outcomes the earlier that this is identified and the earlier that damage control hematology is instituted. Current evidence does not describe the best ratio but the preponderance of the data suggests it should be greater than 2: 3 plasma-to-packed red blood cells.

Abstract
Injury is rapidly becoming the leading cause of death worldwide, and uncontrolled hemorrhage is the leading cause of potentially preventable death. In addition to crystalloid and/or colloid based resuscitation, severely injured trauma patients are routinely transfused RBCs, plasma, platelets, and in some centers either cryoprecipitate or fibrinogen concentrates or whole blood. Optimal timing and quantity of these products in the treatment of hypothermic, coagulopathic and acidotic trauma patients is unclear. The immediate availability of these components is important, as most hemorrhagic deaths occur within the first 3-6h of patient arrival. While there are strongly held opinions and longstanding traditions in their use, there are little data within which to logically guide resuscitation therapy. Many current recommendations are based on euvolemic elective surgery patients and incorporate laboratory data parameters not widely available in the first few minutes after patient arrival. Finally, blood components themselves have evolved over the last 30 years, with great attention paid to product safety and inventory management, yet there are surprisingly limited clinical outcome data describing the long term effects of these changes, or how the components have improved clinical outcomes compared to whole blood therapy. When focused on survival of the rapidly bleeding trauma patient, it is unclear if current component therapy is equivalent to whole blood transfusion. In fact data from the current war in Iraq and Afghanistan suggest otherwise. All of these factors have contributed to the current situation, whereby blood component therapy is highly variable and not driven by long term patient outcomes. This review will address the issues raised above and describe recent trauma patient outcome data utilizing predetermined plasma:platelet:RBC transfusion ratios and an ongoing prospective observational trauma transfusion study.

Abstract
INTRODUCTION Recent retrospective studies have found high fresh frozen plasma (FFP) to packed red blood cell (PRBC) ratios during trauma resuscitation to be associated with improved mortality. Whilst this association may be related to a mortality bias present in these studies, there has been an overall tendency towards a 1:1 FFP:PRBC ratio in massive transfusion guidelines worldwide. The aim of this study was to retrospectively review the administration of FFP in patients undergoing massive transfusion during trauma resuscitation, to add to the evidence base for massive transfusion guidelines. MATERIALS AND METHODS Multi-trauma patients who were administered blood transfusions of 5units or more of packed red blood cells (PRBCs) in the first 4h were included in this study. Mortality was the primary endpoint with length of hospital stay, ICU hours and mechanically ventilated hours secondary endpoints. RESULTS There were 331 patients included in this study with a median Injury Severity Score (ISS) of 36 (25-50) and a mortality of 29.9%. There was little change in the ratio of FFP:PRBC transfused per patient from 2005 to 2008. A low FFP:PRBC ratio in the first 4h of resuscitation, older age, low initial GCS and coagulopathy on presentation were significant independent factors associated with mortality. When deaths in the first 24h were excluded, the FFP:PRBC ratio had no association with mortality. DISCUSSION This study has shown increased initial survival in association with higher FFP:PRBC ratios during massive transfusion in a population with a high proportion of blunt injuries. The association is difficult to interpret because of an inherent survival bias. The optimal ratio of FFP:PRBC during massive transfusion may be different to 1:1 and further prospective research is required. There is now an increasing need for well designed randomised controlled trials to determine the best FFP:PRBC ratio for the resuscitation of blunt multi-trauma patients.

Abstract
Massive transfusion (MT) is used for the treatment of uncontrolled hemorrhage. Earlier definitive control of life-threatening hemorrhage has significantly improved patient outcomes, but MT is still required. A number of recent advances in the area of MT have emerged, including the use of "hypotensive" or "delayed" resuscitation for victims of penetrating trauma before hemorrhage is controlled and "hemostatic resuscitation" with increased use of plasma and platelet transfusions in an attempt to maintain coagulation. These advances include the earlier use of hemostatic blood products (plasma, platelets, and cryoprecipitate), recombinant factor VIIa as an adjunct to the treatment of dilutional and consumptive coagulopathy, and a reduction in the use of isotonic crystalloid resuscitation. MT protocols have been developed to simplify and standardize transfusion practices. The authors of recent studies have advocated a 1:1:1 ratio of packed RBCs to fresh frozen plasma to platelet transfusions in patients requiring MT to avoid dilutional and consumptive coagulopathy and thrombocytopenia, and this has been associated with decreased mortality in recent reports from combat and civilian trauma. Earlier assessment of the exact nature of abnormalities in hemostasis has also been advocated to direct specific component and pharmacologic therapy to restore hemostasis, particularly in the determination of ongoing fibrinolysis.

Abstract
Recent military experience suggests that transfusing fresh frozen plasma and packed red cells in a 1:1 ratio may improve survival in exsanguinating trauma patients. We report the case of a single patient who required massive transfusion after suffering a single gunshot wound. Initially, the patient received FFP:PRBC in 1:2 ratio, but this did not correct laboratory parameters except for INR and clotting factor VII level, which were likely normalized by treatment with recombinant activated factor VII. After receiving FFP:PRBC in a 4:5 ratio, he continued to bleed and his coagulation profile showed no appreciable improvement. In the final phase, he received FFP:PRBC in a 7:5 ratio and his laboratory parameters of coagulopathy normalized, except for factor V level which was improved. He also clinically stopped bleeding.

Abstract
The transfusion approach to massive hemorrhage has continually evolved since it began in the early 1900s. It started with fresh whole blood and currently consists of virtually exclusive use of component and crystalloid therapy. Recent US military experience has reinvigorated the debate on what the most optimal transfusion strategy is for patients with traumatic hemorrhagic shock. In this review we discuss recently described mechanisms that contribute to traumatic coagulopathy, which include increased anti-coagulation factors and hyperfibrinolysis. We also describe the concept of damage control resuscitation (DCR), an early and aggressive prevention and treatment of hemorrhagic shock for patients with severe life-threatening traumatic injuries. The central tenants of DCR include hypotensive resuscitation, rapid surgical control, prevention and treatment of acidosis, hypothermia, and hypocalcemia, avoidance of hemodilution, and hemostatic resuscitation with transfusion of red blood cells, plasma, and platelets in a 1:1:1 unit ratio and the appropriate use of coagulation factors such as rFVIIa and fibrinogen-containing products (fibrinogen concentrates, cryoprecipitate). Fresh whole blood is also part of DCR in locations where it is available. Additional concepts to DCR since its original description that can be considered are the preferential use of "fresh" RBCs, and when available thromboelastography to direct blood product and hemostatic adjunct (anti-fibrinolytics and coagulation factor) administration. Lastly we discuss the importance of an established massive transfusion protocol to rapidly employ DCR and hemostatic resuscitation principles. While the majority of recent trauma transfusion papers are supportive of these general concepts, there is no Level 1 or 2 data available. Taken together, the preponderance of data suggests that these concepts may significantly decrease mortality in massively transfused trauma patients.

Abstract
BACKGROUND Recent data from military and civilian centers suggest that mortality is decreased in massive transfusion patients by increasing the transfusion ratio of plasma and platelet (PLT) products, and fibrinogen in relationship to red blood cell (RBC) products during damage control resuscitation and surgery. This study investigates the relationship of plasma:RBC, PLT:RBC, and cryoprecipitate:RBC transfusion ratios to mortality in massively transfused patients at a civilian Level 1 trauma center. STUDY DESIGN AND METHODS Demographic, laboratory, transfusion, and outcome data were collected prospectively from February 1, 2007, to January 31, 2009, and retrospectively from February 1, 2005, to January 31, 2007, on all injured patients who underwent massive transfusion (defined as >or=10 RBC products within 24 hr). Mortality was analyzed in relation to the plasma:RBC, PLT:RBC, and cryoprecipitate:RBC transfusion ratios using both univariate and multivariate analyses. RESULTS A total of 214 patients received massive transfusion secondary to traumatic injury. High versus low transfusion ratios were associated with improved 30-day survival: plasma:RBC 59% versus 44%, p = 0.03; PLT:RBC 63% versus 33%, p < 0.01; and cryoprecipitate:RBC 66% versus 41%, p < 0.01. By multivariable stepwise logistic regression analysis, increased plasma:RBC (p = 0.02) and PLT:RBC (p = 0.02), and decreased age (p = 0.02), ISS (p < 0.01) and total RBCs (p = 0.03) were statistically associated with improved 30-day survival. CONCLUSIONS In the civilian setting, plasma, PLT, and cryoprecipitate products significantly increased 30-day survival in trauma patients. Future prospective randomized clinical trials are required to determine the optimal transfusion ratios.
