Djaja YP, Silitonga J, Dilogo IH, Mauffrey OJ. The management of pelvic ring fractures in low-resource environments: review. EUROPEAN JOURNAL OF ORTHOPAEDIC SURGERY & TRAUMATOLOGY : ORTHOPEDIE TRAUMATOLOGIE 2023; 33:515-523. [PMID: 36333484 DOI: 10.1007/s00590-022-03420-x] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/30/2022] [Accepted: 10/20/2022] [Indexed: 11/06/2022]
Abstract
Although improvement of pelvic trauma care has been successful in decreasing mortality rates in major trauma centers, such changes have not been implemented in low-resource environments such as low-middle-income countries (LMICs). This review details the evaluation and management of pelvic ring fractures and recommends improvements for trauma care in low-resource environments. Prehospital management revolves around basic life support techniques. Application of non-invasive pelvic circumferential compression devices, such as bed sheet or pelvic binders, can be performed as early as the scene of the accident. Upon arrival at the emergency department, rapid clinical evaluation and immediate resuscitation should be performed. Preperitoneal pelvic packing and external fixation devices have been considered as important first-line management tools to achieve bleeding control in hemodynamically unstable patients. After patient stabilization, immediate referral is mandated if the hospital does not have an orthopedic surgeon or facilities to perform complex pelvic/acetabular surgery. Telemedicine platforms have emerged as one of the key solutions for informing decision-making. However, unavailable referral systems and inaccessible transportation systems act as significant barriers in LMICs. Tendencies toward more "old-fashioned" protocols and conservative treatments are often justified especially for minimally displaced fractures. But when surgery is needed, it is important to visualize the fracture site to obtain and maintain a good reduction in the absence of intraoperative imaging. Minimizing soft tissue damage, reducing intraoperative blood loss, and minimizing duration of surgical interventions are vital when performing pelvic surgery in a limited intensive care setting.

Abstract
Purpose Adequate resuscitation and definitive hemostasis are both important in the management of hemorrhage related to pelvic fracture. The goal of this study was to analyze the relationship between the amount of blood transfused before transcatheter arterial embolization (TAE) and the clinical outcome later in the disease course. Methods Patients with pelvic fractures who underwent TAE for hemostasis from January 2018 to December 2019 were studied. The characteristics of patients who received blood transfusions of >2 U (1000 mL) and ≤2 U before TAE were compared. The mortality rate, blood transfusion-related complications, and length of stay were compared between these two groups. Results Among the 75 studied patients, 39 (52.0%) received blood transfusions of ≤2 U before TAE, and the other 36 (48.0%) patients received blood transfusions of >2 U before TAE. The incidence rates of systemic inflammatory response syndrome, sepsis, and coagulopathy were significantly higher in the >2 U group (97.2% vs 81.1%, P = .027; 50.0% vs 27.0%, P = .045; and 44.4% vs 5.4%, P < .01, respectively). After nonsurvivors were excluded, the >2 U group had a significantly higher proportion (43.8% vs 14.7%, P < .001) of prolonged intensive care unit (ICU) length of stay (7 days or more) and a longer hospital length of stay (33.8 ± 15.1 vs 21.9 ± 94.0, P < .01) than the ≤2 U group. Pre-TAE blood transfusion >2 U serves as an independent risk factor for prolonged ICU length of stay and increased hospital length of stay. Conclusion Early hemostasis for pelvic fracture-related hemorrhage is suggested to prevent pre-TAE blood transfusion-associated adverse effects of blood transfusion.

Abstract
Early recognition of coagulopathy is necessary for its prompt correction and successful management. Novel approaches, such as point-of-care testing (POC) and administration of coagulation factor concentrates (CFCs), aim to tailor the haemostatic therapy to each patient and thus reduce the risks of over- or under-transfusion. CFCs are an effective alternative to ratio-based transfusion therapies for the correction of different types of coagulopathies. In case of major bleeding or urgent surgery in patients treated with vitamin K antagonist anticoagulants, prothrombin complex concentrate (PCC) can effectively reverse the effects of the anticoagulant drug. Evidence for PCC effectiveness in the treatment of direct oral anticoagulants-associated bleeding is also increasing and PCC is recommended in guidelines as an alternative to specific reversal agents. In trauma-induced coagulopathy, fibrinogen concentrate is the preferred first-line treatment for hypofibrinogenaemia. Goal-directed coagulation management algorithms based on POC results provide guidance on how to adjust the treatment to the needs of the patient. When POC is not available, concentrate-based management can be guided by other parameters, such as blood gas analysis, thus providing an important alternative. Overall, tailored haemostatic therapies offer a more targeted approach to increase the concentration of coagulation factors in bleeding patients than traditional transfusion protocols.

Abstract
BACKGROUND Platelet transfusion during major hemorrhage is important and often embedded in massive transfusion protocols. However, the optimal ratio of platelets to erythrocytes (platelet-rich plasma [PLT]/red blood cell [RBC] ratio) remains unclear. We hypothesized that high PLT/RBC ratios, as compared with low PLT/RBC ratios, are associated with improved survival in patients requiring massive transfusion. METHODS Four databases (Pubmed, CINAHL, EMBASE, and Cochrane) were systematically screened for literatures published until January 21, 2021, to determine the effect of PLT/RBC ratio on the primary outcome measure mortality at 1 hour to 6 hours and 24 hours and at 28 days to 30 days. Studies comparing various PLT/RBC ratios were included in the meta-analysis. Secondary outcomes included intensive care unit length of stay and in-hospital length of stay and total blood component use. The study protocol was registered in PROSPERO under number CRD42020165648. RESULTS The search identified a total of 8903 records. After removing the duplicates and second screening of title, abstract, and full text, a total of 59 articles were included in the analysis. Of these articles, 12 were included in the meta-analysis. Mortality at 1 hour to 6 hours, 24 hours, and 28 days to 30 days was significantly lower for high PLT/RBC ratios as compared with low PLT/RBC ratios. CONCLUSION Higher PLT/RBC ratios are associated with significantly lower 1-hour to 6-hour, 24-hour, 28-day to 30-day mortalities as compared with lower PLT/RBC ratios. The optimal PLT/RBC ratio for massive transfusion in trauma patients is approximately 1:1. LEVEL OF EVIDENCE Systematic review and meta-analysis, therapeutic Level III.

Abstract
Pelvic ring injuries (PRI) are among the most difficult injuries to deal with in orthopedic trauma. When these injuries are accompanied by hemodynamic instability their management becomes significantly more complex. A methodical assessment and expeditious triage are required for these patients followed by adequate resuscitation. A major triage decision is whether these patients should undergo arterial embolization in the angiography suit or prompt packing and pelvic stabilization in the operating room. Patient characteristics, fracture type and injury characteristics are taken into consideration in the decision-making process. In this review we discuss the acute evaluation, triage and management of PRIs associated with hemodynamic instability. An evidence based and protocol driven approach is necessary in order to achieve optimal outcomes in these patients.

Abstract
BACKGROUND Hemorrhage, especially when complicated by coagulopathy, is the most preventable cause of death in trauma patients. We hypothesized that assessing hemostatic function using rotational thromboelastometry (ROTEM) or conventional coagulation tests can predict the risk of mortality in patients with severe trauma indicated by an injury severity score greater than 15. METHODS We retrospectively reviewed trauma patients with an injury severity score >15 who were admitted to the emergency department between November 2015 and August 2017 in a single level I trauma center. Patients with available ROTEM and conventional coagulation data (partial thromboplastin time [PTT], prothrombin time [PT], and international normalized ratio) were included in the study cohort. Logistic regression was performed to assess the relationship between coagulation status and mortality. RESULTS The study cohort included 301 patients with an average age of 47 y, and 75% of the patients were males. Mortality was 23% (n = 68). Significant predictors of mortality included abnormal APTEM (thromboelastometry (TEM) assay in which fibrinolysis is inhibited by aprotinin (AP) in the reagent) parameters, specifically a low APTEM alpha angle, a high APTEM clot formation time, and a high APTEM clotting time. In addition, an abnormal international normalized ratio significantly predicted mortality, whereas abnormal PT and PTT did not. CONCLUSIONS A low APTEM alpha angle, an elevated APTEM clot formation time, and a high APTEM clotting time significantly predicted mortality, whereas abnormal PT and PTT did not appear to be associated with increased mortality in this patient population. Viscoelastic testing such as ROTEM appears to have indications in the management and stabilization of trauma patients.

Early administration of fibrinogen concentrate is associated with improved survival among severe trauma patients: a single-centre propensity score-matched analysis. World J Emerg Surg 2020; 15:7.

Abstract
Background Fibrinogen plays an important role in haemostasis during the early phase of trauma, and low fibrinogen levels after severe trauma are associated with haemostatic impairment, massive bleeding, and poor outcomes. Aggressive fibrinogen supplementation may improve haemostatic function, as fibrinogen levels deteriorate before other routine coagulation parameters in this setting. Therefore, we evaluated whether early administration of fibrinogen concentrate (FC) was associated with improved survival in severe trauma patients. Methods This single-centre retrospective study evaluated patients with severe trauma (injury severity score ≥ 16) who were admitted to our emergency department between January 2010 and July 2018. The exclusion criteria included age < 18 years, cardiac arrest before emergency department arrival, cervical spinal cord injury not caused by a high-energy accident, and severe burn injuries. The FC and control groups included trauma patients who received and did not receive FC within 1 h after emergency department arrival, respectively. Propensity scores were used to balance the two groups based on the trauma and injury severity score (TRISS), heart rate at emergency department admission, and age. The primary outcome was the in-hospital survival rate. Results The propensity scoring model had a c-statistic of 0.734, the Hosmer-Lemeshow chi-squared value was 7.036 (degrees of freedom = 8), and the non-significant p value of 0.533 indicated a good model fit. The propensity score matching created 31 matched pairs of patients, who had appropriately balanced characteristics. The FC group had a significantly higher in-hospital survival rate than the control group (log-rank p = 0.013). The FC group also used significantly higher amounts of red blood cells and fresh frozen plasma within 6 h after emergency department admission. However, the two groups had similar transfusion amounts between 6 and 24 h after emergency department admission. Conclusions The present study revealed that early FC administration was associated with a favourable survival rate among severe trauma patients. Therefore, FC may be useful for the early management of trauma-induced coagulopathy and may improve outcomes in this setting.

Ten-year evolution of a massive transfusion protocol in a level 1 trauma centre: have outcomes improved? ANZ J Surg 2019; 89:1470-1474.

Abstract
Background We aimed to evaluate the evolution and implementation of the massive transfusion protocol (MTP) in an urban level 1 trauma centre. Most data on this topic comes from trauma centres with high exposure to life‐threatening haemorrhage. This study examines the effect of the introduction of an MTP in an Australian level 1 trauma centre. Methods A retrospective study of prospectively collected data was performed over a 14‐year period. Three groups of trauma patients, who received more than 10 units of packed red blood cells (PRBC), were compared: a pre‐MTP group (2002–2006), an MTP‐I group (2006–2010) and an MTP‐II group (2010–2016) when the protocol was updated. Key outcomes were mortality, complications and number of blood products transfused. Results A total of 168 patients were included: 54 pre‐MTP patients were compared to 47 MTP‐I and 67 MTP‐II patients. In the MTP‐II group, fewer units of PRBC and platelets were administered within the first 24 h: 17 versus 14 (P = 0.01) and 12 versus 8 (P < 0.001), respectively. Less infections were noted in the MTP‐I group: 51.9% versus 31.9% (P = 0.04). No significant differences were found regarding mortality, ventilator days, intensive care unit and total hospital lengths of stay. Conclusion Introduction of an MTP‐II in our level 1 civilian trauma centre significantly reduced the amount of PRBC and platelets used during damage control resuscitation. Introduction of the MTP did not directly impact survival or the incidence of complications. Nevertheless, this study reflects the complexity of real‐life medical care in a level 1 civilian trauma centre.

Abstract
D-dimer is a potential biomarker for the detection of traumatic brain injury (TBI). However, the mechanisms that trigger elevation of D-dimer in TBI remain unclear. The purpose of this study was to evaluate the reliability of D-dimer in blood as a biomarker for TBI and to determine the mechanisms involved in regulating its blood levels. Nine patients with moderate to severe isolated TBI (Glasgow Coma Scale [GCS] score 7–13) were admitted to our hospital from May 2013 to June 2014. Blood samples were collected from systemic arteries on arrival and at 1, 3, 5, and 7 days after injury. Blood levels of neuron specific enolase (NSE), D-dimer, and soluble tissue factor (sTF) were measured. NSE (33.4 ng/ml: normal <12.0 ng/ml) and D-dimer (56.1 μg/ml: normal <1.0 μg/ml) were elevated at admission and declined on day 1 after injury. At admission, there were significant correlations of D-dimer levels with NSE (R = 0.727, P = 0.026) and sTF (R = 0.803, P = 0.009) levels. The blood level of D-dimer accurately reflects the degree of brain tissue damage indicated by NSE levels. Our data suggest that release of sTF induced by brain tissue damage may activate the coagulation cascade, leading to elevation of D-dimer.

Abstract
A 53-year-old female was admitted to the emergency department with an exsanguinating bleed from the rectum which was of unclear origin. In what could be considered an ultramassive transfusion, 60 units packed red blood cells, 23 units fresh frozen plasma, 20 units platelets, 6 units cryoprecipitate, 30 L of crystalloids, 2 L of colloids, and 4 g of tranexamic acid were transfused over the course of 7 h. An arterio-enteric fistula was diagnosed and treated by an interventional radiologist. The patient recovered rapidly thereafter without any major neurologic, pulmonary, cardiac, or hematologic complications.

Abstract
Objective This study aimed to determine the precision dose of Chinese universal pooled plasma (CUPP) developed by our laboratory, and the stability of plasma proteins and factors. Methods A total of 100 single fresh-frozen plasma (FFP) units were selected to test plasma proteins, including total protein, albumin, fibrinogen, factor V, factor VIII, antithrombin-III, and protein C. Different pooling protocols with 20, 40, 60, 80, and 100 units were used to optimize the number of pooled units. The pooled plasma was then used to further evaluate the optimal storage conditions and duration at 22°C, 4°C, and −20°C. Results There were considerable differences in plasma protein levels among single units of FFP. After different pooling protocols, the mean value of plasma proteins did not significantly change. However, with a larger number of pooled samples, plasma proteins were more stable with a smaller standard deviation. Acceptable storage for CUPP was achieved with storage for 1 day at 22°C, 4 days at 4°C, and 3 months at −20°C. Conclusion A uniform level of plasma proteins and factors in CUPP appears to support establishment of a precise dose of plasma.

Abstract
The advent of massive transfusion protocols (MTP) has had a significant positive impact on hemorrhaging trauma patient morbidity and mortality. Nevertheless, societal MTP guidelines and individual MTPs at academic institutions continue to circulate opposing recommendations on topics critical to MTPs. This narrative review discusses up-to-date information on 2 such topics, the initiation and termination of an MTP. The discussion for each begins with a review of the recommendations and supporting literature presented by MTP guidelines from 3 prominent societies, the American Society of Anesthesiologists, the American College of Surgeons, and the task force for Advanced Bleeding Care in Trauma. This is followed by an in-depth analysis of the main components within those recommendations. Societal recommendations on MTP initiation in hemorrhaging trauma patients emphasize the use of retrospectively validated massive transfusion (MT) prediction score, specifically, the Assessment of Blood Consumption and Trauma-Associated Severe Hemorrhage scores. Validation studies have shown that both scoring systems perform similarly. Both scores reliably identify patients that will not require an MT, while simultaneously overpredicting MT requirements. However, each scoring system has its unique advantages and disadvantages, and this review discusses how specific aspects of each scoring system can affect widespread applicability and statistical performance. In addition, we discuss the often overlooked topic of initiating MT in nontrauma patients and the specific tools physicians have to guide the MT initiation decision in this unique setting. Despite the serious complications that can arise with transfusion of large volumes of blood products, there is considerably less research pertinent to the topic of MTP termination. Societal recommendations on MTP termination emphasize applying clinical reasoning to identify patients who have bleeding source control and are adequately resuscitated. This review, however, focuses primarily on the recommendations presented by the Advanced Bleeding Care in Trauma's MTP guidelines that call for prompt termination of the algorithm-guided model of resuscitation and rapidly transitioning into a resuscitation model guided by laboratory test results. We also discuss the evidence in support of laboratory result-guided resuscitation and how recent literature on viscoelastic hemostatic assays, although limited, highlights the potential to achieve additional benefits from this method of resuscitation.

Abstract
Hemorrhage is the most important contributing factor of acute-phase mortality in trauma patients. Previously, traumatologists and investigators identified iatrogenic and resuscitation-associated causes of coagulopathic bleeding after traumatic injury, including hypothermia, metabolic acidosis, and dilutional coagulopathy that were recognized as primary drivers of bleeding after trauma. However, the last 10 years has seen a widespread paradigm shift in the resuscitation of critically injured patients, and there has been a dramatic evolution in our understanding of trauma-induced coagulopathy. Although there is no consensus regarding a definition or an approach to the classification and naming of trauma-associated coagulation impairment, trauma itself and/or traumatic shock-induced endogenous coagulopathy are both referred to as acute traumatic coagulopathy (ATC), and multifactorial trauma-associated coagulation impairment, including ATC and resuscitation-associated coagulopathy is recognized as trauma-induced coagulopathy. Understanding the pathophysiology of trauma-induced coagulopathy is vitally important, especially with respect to the critical issue of establishing therapeutic strategies for the management of patients with severe trauma.

Abstract
OBJECTIVE To determine the effectiveness of blood component therapy in the correction of trauma-induced coagulopathy during hemorrhage. BACKGROUND Severe hemorrhage remains a leading cause of mortality in trauma. Damage control resuscitation strategies target trauma-induced coagulopathy (TIC) with the early delivery of high-dose blood components such as fresh frozen plasma (FFP) and platelet transfusions. However, the ability of these products to correct TIC during hemorrhage and resuscitation is unknown. METHODS This was an international prospective cohort study of bleeding trauma patients at three major trauma centers. A blood sample was drawn immediately on arrival and after 4, 8 and 12 packed red blood cell (PRBC) transfusions. FFP, platelet and cryoprecipitate use was recorded during these intervals. Samples were analyzed for functional coagulation and procoagulant factor levels. RESULTS One hundred six patients who received at least four PRBC units were included. Thirty-four patients (32 %) required a massive transfusion. On admission 40 % of patients were coagulopathic (ROTEM CA5 ≤ 35 mm). This increased to 58 % after four PRBCs and 81 % after eight PRBCs. On average all functional coagulation parameters and procoagulant factor concentrations deteriorated during hemorrhage. There was no clear benefit to high-dose FFP therapy in any parameter. Only combined high-dose FFP, cryoprecipitate and platelet therapy with a high total fibrinogen load appeared to produce a consistent improvement in coagulation. CONCLUSIONS Damage control resuscitation with standard doses of blood components did not consistently correct trauma-induced coagulopathy during hemorrhage. There is an important opportunity to improve TIC management during damage control resuscitation.

Abstract
Traumatic injuries represent a major health problem all over the world. In recent years we have witnessed profound changes in the paradigm of severe trauma patient resuscitation, new concepts regarding acute coagulopathy in trauma have been proposed, and there has been an expansion of specific commercial products related to hemostasis, among other aspects. New strategies in severe trauma management include the early identification of those injuries that are life threatening and require surgical hemostasis, tolerance of moderate hypotension, rational intravascular volume replacement, prevention of hypothermia, correction of acidosis, optimization of oxygen carriers, and identification of those factors required by the patient (fresh frozen plasma, platelets, tranexamic acid, fibrinogen, cryoprecipitates and prothrombin complex). However, despite such advances, further evidence is required to improve survival rates in severe trauma patients.

Abstract
PURPOSE Recent studies have shown increased survival benefits when a high fresh frozen plasma (FFP) to packed red blood cell (PRBC) ratio is used during trauma resuscitation. However, some reports have raised questions about the effect of higher FFP:PRBC transfusion ratios. The aim of this study was to examine the efficacy of high FFP:PRBC ratios in injured patients with regard to survival and morbidity in a single tertiary emergency center in Japan. METHODS This study examined severe trauma patients who received 10 or more PRBC units during the first 24 h of admission. We examined the relationship between the FFP:PRBC ratios during the first 6 h and the patient outcome. RESULTS The severity was similar among all groups. The mortality rate was 44.4% in the high (>1:1.5), 16.7% in the middle (1:1.5-1:2) and 33.3% in the low (<1:2) F:P ratio groups. Only one patient in the high group developed sepsis, and none of the patients developed ARDS. CONCLUSIONS The current results indicate that the FFP:PRBC ratios during the first 6 h after admission might not affect the mortality or morbidity. However, differences between trauma care systems in Japan and other countries, along with other study limitations, necessitate that a subsequent prospective multicenter study be undertaken before any definitive conclusions can be made.

Abstract
PURPOSE Massive transfusion has recently been given a dynamic definition, namely, the replacement of more than four red cell concentrates within an hour. The purpose of this continuing professional development module is to review the pathophysiology of hemorrhagic shock in the trauma patient and the current management strategies of the massively bleeding trauma patient. PRINCIPAL FINDINGS The massively bleeding trauma patient requires concurrent hemorrhage control and blood replacement therapy. Although there are many complications of massive transfusions, such as acid-base disturbances, electrolyte abnormalities, and hypothermia, perhaps the most difficult aspect to manage is acute trauma coagulopathy. Historically, coagulopathy was attributed to dilution of coagulation factors; however, recent accumulated evidence indicates that it is a multifactorial process associated with hypoperfusion, factor consumption, and hyperfibrinolysis. In an attempt to minimize acute trauma coagulopathy, massive transfusion protocols with equal ratios of red cell concentrates, frozen plasma, and platelets have been proposed. This type of hemostatic resuscitation, with near equal ratios of blood and blood products, has improved survival, but it is not without risk. In addition to the rapid and effective restoration of blood volume, the specific goal of transfusion management should be to maintain the patient's oxygen carrying capacity, hemostasis, and biochemistry. CONCLUSION The current literature does not permit firm conclusions to be drawn regarding optimal transfusion ratios. It remains appropriate, however, to devise a massive transfusion protocol at the institutional level that provides treating physicians with rapid delivery of a reasonable initial ratio of products. This would permit patient-centred management with an emphasis on surgical control of bleeding, maintenance of normothermia, avoidance of electrolyte abnormalities, acid-base balance, and the timely delivery of blood products. OBJECTIVES After reading this module, the reader should be able to: 1. Enumerate the complications associated with massive transfusion in the trauma context; 2. Understand how the coagulopathy present in the trauma patient differs from that seen in the elective setting; 3. Identify the modifications suggested by the recent literature for the management of massive transfusion in the trauma setting; 4. Appreciate the evidence for the institution of massive transfusion protocols.

Abstract
Severe trauma-related bleeding is associated with high mortality. Standard coagulation tests provide limited information on the underlying coagulation disorder. Whole-blood viscoelastic tests such as rotational thromboelastometry or thrombelastography offer a more comprehensive insight into the coagulation process in trauma. The results are available within minutes and they provide information about the initiation of coagulation, the speed of clot formation, and the quality and stability of the clot. Viscoelastic tests have the potential to guide coagulation therapy according to the actual needs of each patient, reducing the risks of over- or under-transfusion. The concept of early, individualized and goal-directed therapy is explored in this review and the AUVA Trauma Hospital algorithm for managing trauma-induced coagulopathy is presented.

Abstract
OBJECTIVE To identify an appropriate diagnostic tool for the early diagnosis of acute traumatic coagulopathy and validate this modality through prediction of transfusion requirements in trauma hemorrhage. DESIGN Prospective observational cohort study. SETTING Level 1 trauma center. PATIENTS Adult trauma patients who met the local criteria for full trauma team activation. Exclusion criteria included emergency department arrival >2 hrs after injury, >2000 mL of intravenous fluid before emergency department arrival, or transfer from another hospital. INTERVENTIONS None. MEASUREMENTS Blood was collected on arrival in the emergency department and analyzed with laboratory prothrombin time, point-of-care prothrombin time, and rotational thromboelastometry. Prothrombin time ratio was calculated and acute traumatic coagulopathy defined as laboratory prothrombin time ratio >1.2. Transfusion requirements were recorded for the first 12 hrs following admission. MAIN RESULTS Three hundred patients were included in the study. Laboratory prothrombin time results were available at a median of 78 (62-103) mins. Point-of-care prothrombin time ratio had reduced agreement with laboratory prothrombin time ratio in patients with acute traumatic coagulopathy, with 29% false-negative results. In acute traumatic coagulopathy, the rotational thromboelastometry clot amplitude at 5 mins was diminished by 42%, and this persisted throughout clot maturation. Rotational thromboelastometry clotting time was not significantly prolonged. Clot amplitude at a 5-min threshold of ≤35 mm had a detection rate of 77% for acute traumatic coagulopathy with a false-positive rate of 13%. Patients with clot amplitude at 5 mins ≤35 mm were more likely to receive red cell (46% vs. 17%, p < .001) and plasma (37% vs. 11%, p < .001) transfusions. The clot amplitude at 5 mins could identify patients who would require massive transfusion (detection rate of 71%, vs. 43% for prothrombin time ratio >1.2, p < .001). CONCLUSIONS In trauma hemorrhage, prothrombin time ratio is not rapidly available from the laboratory and point-of-care devices can be inaccurate. Acute traumatic coagulopathy is functionally characterized by a reduction in clot strength. With a threshold of clot amplitude at 5 mins of ≤35 mm, rotational thromboelastometry can identify acute traumatic coagulopathy at 5 mins and predict the need for massive transfusion.

Abstract
The severely injured trauma patient often arrives in the emergency department bleeding, coagulopathic and in need of a blood transfusion. The diagnosis and management of these patients has vastly improved with a better understanding of acute traumatic coagulopathy (ATC). In the emergency setting, traditional laboratory coagulation screens are of limited use in the diagnosis and management of life-threatening bleeding. Whole blood assays, such as thrombelastography (TEG) and rotational thrombelastometry (ROTEM) provide a rapid evaluation of clot formation, strength and lysis. Rapid diagnosis of ATC and aggressive haemostatic transfusion strategies utilizing early high doses of plasma are associated with improved outcomes in trauma. At present there is no accurate guide for transfusion in trauma, therefore blood and clotting products are administered on an empiric basis. Targeted transfusion therapy for major trauma haemorrhage based on comprehensive and rapid measures of coagulation e.g. TEG/ROTEM may lead to improved outcomes while optimizing blood utilization. Evidence for the clinical application of TEG and ROTEM in trauma is emerging with a number of studies evaluating their ability to diagnose coagulopathy early and facilitate goal-directed transfusion. This review explores current controversies and best practice in the diagnosis and management of major haemorrhage in trauma.

Abstract
This retrospective study evaluates changes in transfusion practice and modified blood product utilisation that occurred over the course of eleven years in patients receiving massive transfusion. The mean number of fresh frozen plasma units transfused increased from 9.0 ± 7.9 in 1998 to 11.3 ± 6.7 in 2008 (p=0.03). The mean number of platelet units increased from 1.9 ± 1.3 in 1998 to 2.6 ± 1.7 in 2008 (p=0.02). The proportion of cryoprecipitate increased from 0.03 ± 0.19 in 1998 to 1.3 ± 1.6 in 2008 (p=0.001). Along with these changes was a trend toward decreased mortality (p=0.05).

Abstract
Transfusion medicine for the resuscitation of patients with massive hemorrhage has recently advanced from reactive, supportive treatment with crystalloid and red blood cell therapy to use of standardized massive transfusion protocols (MTPs). Through MTPs, medical facilities are able to standardize the most effective posthemorrhage treatments and execute them rapidly while reducing potential waste of blood products. Damage control resuscitation is an example of an MTP, where patients are (1) allowed more permissive hypotension, (2) spared large volumes of crystalloid/colloid therapy (through low volume resuscitation), and (3) transfused with blood products preemptively using a balanced ratio of plasma and platelets to red blood cells. This focused approach improves the timely availability of blood components during resuscitation. However, the use of MTPs remains controversial. This review describes published experiences with MTPs and illustrates the potential value of several MTPs currently utilized by academic transfusion services.

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
BACKGROUND Severe bleeding and coagulopathy as a result of massive transfusion are serious clinical conditions that are associated with high mortality. Thromboelastography (TEG) and thromboelastometry (ROTEM) are increasingly used to guide transfusion strategy but their roles remain disputed. OBJECTIVES To systematically assess the benefits and harms of a TEG or ROTEM guided transfusion strategy in randomized trials involving patients with severe bleeding. SEARCH STRATEGY Randomized clinical trials (RCTs) were identified from electronic databases: Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2010, Issue 9); MEDLINE; EMBASE; Science Citation Index Expanded; International Web of Science; CINAHL; LILACS; and the Chinese Biomedical Literature Database (up to 31st October 2010). We contacted trial authors, authors of previous reviews, and manufacturers in the field. SELECTION CRITERIA We included all RCTs, irrespective of blinding or language, that compared transfusion guided by TEG or ROTEM to transfusion guided by clinical judgement and standard laboratory tests, or both. DATA COLLECTION AND ANALYSIS Two authors independently abstracted data; they resolved any disagreements by discussion. We presented pooled estimates of the intervention effects on dichotomous outcomes as relative risks (RR) and on continuous outcomes as mean differences, with 95% confidence intervals (CI). Our primary outcome measure was all cause mortality. We performed subgroup and sensitivity analyses to assess the effect of TEG or ROTEM in adults and children on various clinical and physiological outcomes. We assessed the risk of bias through assessment of trial methodological components and the risk of random error through trial sequential analysis. MAIN RESULTS We included nine RCTs with a total of 776 participants; only one trial had a low risk of bias. We found two ongoing trials but were unable to retrieve any data from them. Compared with standard treatment, TEG or ROTEM showed no statistically significant effect on overall mortality (3.78% versus 5.11%, RR 0.77, 95% CI 0.35 to 1.72; I(2) = 0%) but only five trials provided data on mortality. Our analyses demonstrated a statistically significant effect of TEG or ROTEM on the amount of bleeding (MD -85.05 ml, 95% CI -140.68 to -29.42; I(2) = 26%) but failed to show any statistically significant effect on other predefined outcomes. AUTHORS' CONCLUSIONS There is an absence of evidence that TEG or ROTEM improves morbidity or mortality in patients with severe bleeding. Application of a TEG or ROTEM guided transfusion strategy seems to reduce the amount of bleeding but whether this has implications for the clinical condition of patients is still uncertain. More research is needed.

Abstract
BACKGROUND Damage control resuscitation targets acute traumatic coagulopathy with the early administration of high-dose fresh frozen plasma (FFP). FFP is administered empirically and as a ratio with the number of packed red blood cells (PRBC). There is controversy over the optimal FFP:PRBC ratio with respect to outcomes, and their hemostatic effects have not been studied. We report preliminary findings on the effects of different FFP:PRBC ratios on coagulation. METHODS This is a prospective observational cohort study of trauma patients requiring >4 U of PRBCs. Blood was drawn before and after each 4-U PRBC interval for prothrombin time and analysis by rotational thromboelastometry. Interval change in coagulation parameters were compared with the FFP:PRBC ratio received during each interval. RESULTS Sixty 4-U PRBC intervals from 50 patients were available for analysis. All measures of coagulation deteriorated with low FFP:PRBC ratios (<1:2). Maximal hemostatic effect was observed in the 1:2 to 3:4 group: 12% decrease in prothrombin time (p=0.006), 56% decrease in clotting time (p=0.047), and 38% increase in maximum clot firmness (p=0.024). Transfusion with ≥1:1 ratio did not confer any additional improvement. There was a marked variability in response to FFP, and hemostatic function deteriorated in some patients exposed to 1:1 ratios. The beneficial effects of plasma were confined to patients with coagulopathy. CONCLUSIONS Interim results from this prospective study suggest that FFP:PRBC ratios of ≥1:1 do not confer any additional advantage over ratios of 1:2 to 3:4. Hemostatic benefits of plasma therapy are limited to patients with coagulopathy.

Abstract
INTRODUCTION The massive-transfusion concept was introduced to recognize the dilutional complications resulting from large volumes of packed red blood cells (PRBCs). Definitions of massive transfusion vary and lack supporting clinical evidence. Damage-control resuscitation regimens of modern trauma care are targeted to the early correction of acute traumatic coagulopathy. The aim of this study was to identify a clinically relevant definition of trauma massive transfusion based on clinical outcomes. We also examined whether the concept was useful in that early prediction of massive transfusion requirements could allow early activation of blood bank protocols. METHODS Datasets on trauma admissions over a 1 or 2-year period were obtained from the trauma registries of five large trauma research networks. A fractional polynomial was used to model the transfusion-associated probability of death. A logistic regression model for the prediction of massive transfusion, defined as 10 or more units of red cell transfusions, was developed. RESULTS In total, 5,693 patient records were available for analysis. Mortality increased as transfusion requirements increased, but the model indicated no threshold effect. Mortality was 9% in patients who received none to five PRBC units, 22% in patients receiving six to nine PRBC units, and 42% in patients receiving 10 or more units. A logistic model for prediction of massive transfusion was developed and validated at multiple sites but achieved only moderate performance. The area under the receiver operating characteristic curve was 0.81, with specificity of only 50% at a sensitivity of 90% for the prediction of 10 or more PRBC units. Performance varied widely at different trauma centers, with specificity varying from 48% to 91%. CONCLUSIONS No threshold for definition exists at which a massive transfusion specifically results in worse outcomes. Even with a large sample size across multiple trauma datasets, it was not possible to develop a transportable and clinically useful prediction model based on available admission parameters. Massive transfusion as a concept in trauma has limited utility, and emphasis should be placed on identifying patients with massive hemorrhage and acute traumatic coagulopathy.

Abstract
INTRODUCTION Based on relatively recent clinical work, considerable enthusiasm has been generated for the increased use of plasma and platelet in the earlier resuscitation of massively transfused patients. The aim of this review was to examine the currently available evidence for the increase in plasma/platelet to red cell transfusion ratio during massive transfusion. METHODS In May of 2009, a systematic review of studies reporting the effects of plasma and platelet to red cell component transfusion ratio on mortality outcome was performed. RESULTS There were no prospective randomized controlled trials on this topic. Eleven retrospective studies were identified evaluating the effects of plasma : red cell ratio on mortality in massive transfusion after trauma. Most studies demonstrated a survival advantage of increased plasma ratio in massive transfusion. While the majority of the studies suggested the optimal plasma : red cell ratio to be 1 : 2 or higher, others demonstrated the optimal ratio to be lower. Three of these studies also demonstrated a survival advantage with increased platelet : red cell transfusion ratio. CONCLUSION Although there is some evidence to support the increase use of plasma and platelets in massive transfusion, the true efficacy of such practice has not yet been proven by prospective randomized controlled trials. The available retrospective studies raise many important questions that need to be addressed in future clinical trials.

Abstract
BACKGROUND In trauma patients with significant hemorrhage, it is hypothesized that failure to normalize prothrombin time (PT) after recombinant activated factor VII (rFVIIa) treatment predicts poor clinical outcomes and potentially indicates a need for additional therapeutic interventions. METHODS To assess the value of PT to predict outcomes after rFVIIa or placebo therapy, we performed a post hoc analysis of data from 169 severely injured, critically bleeding trauma patients who had 1-hour postdose PT measurements from two randomized clinical trials. Baseline characteristics and outcome parameters were compared between subjects with 1-hour postdose PT >or=18 seconds and PT <18 seconds. RESULTS In rFVIIa-treated subjects, prolonged postdose PT values >or=18 seconds were associated with significantly higher 24-hour mortality (60% vs. 3%; p < 0.001) and 30-day mortality, increased incidence of massive transfusion, and fewer intensive care unit-free days compared with postdose PT values <18 seconds. Recombinant rFVIIa-treated subjects with postdose PT >or=18 seconds had significantly lower baseline hemoglobin levels, fibrinogen levels, and platelet counts than subjects with postdose PT values <18 seconds even though they received similar amounts of blood products before rFVIIa dosing. Placebo-treated subjects with postdose PT >or=18 seconds had significantly increased incidence of massive transfusion, significantly decreased intensive care unit-free days, and significantly lower levels of fibrinogen and platelets at baseline compared with subjects with postdose PT values <18 seconds. CONCLUSIONS The presence of prolonged PT after rFVIIa or placebo therapy was associated with poor clinical outcomes. Because subjects with postdosing PT >or=18 seconds had low levels of hemoglobin, fibrinogen, and platelets, this group may benefit from additional blood component therapy.

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.

Abstract
Recent observational studies have identified an acute coagulopathy in trauma victims that is present on arrival in the emergency room. It has been associated with a four-fold increase in mortality and increased incidence of organ failure. Conventional trauma resuscitation and transfusion protocols are designed for dilutional coagulopathy and appear inadequate in the management of acute traumatic coagulopathy and massive transfusion. Acute Coagulopathy of Trauma Shock (ACoTS) is caused by a combination of tissue injury and shock, and may occur without significant fluid administration, clotting factor depletion or hypothermia. The mechanism through which acute coagulopathy develops is unclear but activation of the protein C pathway has been implicated. Standard coagulation tests do not identify cases in a timely fashion and ACoTS should be suspected in any trauma patient with a significant magnitude of injury and shock, as evidenced by an abnormal admission base deficit on blood gas. Development of point of care coagulometers and whole blood coagulation analysers, such as rotational thromboelastometry, may enable earlier laboratory identification of this group. Retrospective studies performed by the American military indicate that resuscitation of severely injured patients with higher ratios of plasma given early may improve outcome and reduce overall blood product use. The place of adjunctive pharmaceutical agents within this strategy remains unclear. There is an acute coagulopathy associated with trauma and shock that is an independent predictor of outcomes. Delineation of this entity, with directed management protocols should lead to a reduction in avoidable deaths from haemorrhage after trauma.

Abstract
To evaluate transfusion practices in multiple injured patients and to demonstrate changes in the pattern of packed red blood cell (pRBC) transfusions over the last one-and-half decade (1993-2006). A retrospective analysis using the German Trauma Registry database (DGU-Traumaregister) including 29 353 multiple injured patients was conducted. The study population included primary admissions presenting to the emergency room (ER) with clinical and laboratory signs of active haemorrhage [haemoglobin < 9 g x dL(-1), platelets < 90000 xmicroL(-1) and prothrombin time (Quick-value) < 60%]. The pattern of pRBC transfusions was followed from ER to intensive care unit (ICU) admission. A total of 5389 patients with complete data sets were divided into the following three groups according to the year of treatment and analysed: (a) group 1: 1993-1998 (n = 870), (b) group 2: 1999-2002 (n = 2044) and (c) group 3: 2003-2006 (n = 2475). Patients had a mean age of 40.5 (+/-20) years and were predominantly male (67.2%). All patients were substantially injured (mean injury severity score = 32 +/- 15.5) and in 93% the mechanism of injury was blunt. The percentage of patients who received pRBC transfusions between ER and ICU dropped from 72% in 1993-1998 to 54% in 2003-2006 (P < 0.005). Similarly, the percentage of patients receiving mass transfusions (> 10 pRBC units) dropped from 51.3 to 17.1%. This decline was accompanied by lower incidence rates for septic complications, ventilator days, ICU length-of-stay and mortality. pRBC transfusion practices in acute trauma care have changed substantially over the last one-and-half decade and were associated with better outcome.

Abstract
BACKGROUND Modern publications on response to single explosive events are from non-US hospitals, predate current resuscitation guidelines and lack detail on surgical and intensive care unit (ICU) requirements. The objective of this study is to provide a contemporary account of surge response to multiple casualty incidences following explosive events managed at a US trauma hospital in Iraq. METHODS Observational study and retrospective chart review of 72-hour transfusion, operating room, and ICU resource utilization from 3 multiple casualty incidences managed at the US Air Force Theater Hospital, Balad AB, Iraq between February and April 2008. RESULTS Fifty patients were treated with a mean injury severity score of 19. Forty-eight percent (n = 24) of casualties required blood transfusion with 4 patients receiving 43% (N = 74 units) of the packed red blood cells (pRBC). An average of 3.5 and 3.8 units of pRBC and plasma, respectively, was transfused per casualty (pRBC:plasma ratio of 1:1.1). Seventy-six percent (n = 38) of patients required immediate operation upon initial presentation. A total of 191 procedures were performed in parallel during 75 operations (3.8 procedures per casualty). Fifty percent (n = 25) of patients required ICU admission with nearly the same number (n = 24) requiring mechanical ventilator support beyond that required for operation. All cause, in-hospital mortality was 8% (n = 4). CONCLUSIONS Results from this study provide a contemporary assessment of transfusion, surgical, and intensive care resource requirements after a single explosive event. Data from this experience may translate into useful guidelines for emergency planners worldwide.

Abstract
BACKGROUND Blood transfusion in the management of severely injured patients can be lifesaving. These patients are susceptible to developing early coagulopathy, thus perpetuating bleeding. OBJECTIVES This article presents recent advances in both the civilian and military clinical arena to improve the treatment of trauma patients with severe hemorrhage, the use of agents to support coagulation, perspectives on restrictive transfusion strategies, and transfusion-related risks. DISCUSSION Massive blood transfusion is an adjunct to surgical care. The volume of blood products transfused and the ratio of blood components have been associated with increased morbidity and mortality rates. The adverse clinical effects of transfusion and the limited supply of blood products have resulted in modern resuscitation protocols to limit the volume of blood transfused. CONCLUSION A restrictive blood transfusion strategy and the use of hemostatic agents may decrease morbidity and mortality in trauma patients, but insufficient data are available for their use in trauma patients. Massive transfusion should reflect an equal ratio of packed red cells and plasma to limit coagulopathy. Prospective randomized trials are needed to standardize an effective protocol.
