Abstract
PURPOSE OF REVIEW The diagnosis and treatment of patients with severe traumatic bleeding and subsequent trauma-induced coagulopathy (TIC) is still inconsistent, although the implementation of standardized algorithms/treatment pathways was repeatedly linked to improved outcome. Various evidence-based guidelines for these patients now exist, three of which have recently been updated. RECENT FINDINGS A synopsis of the three recently updated guidelines for diagnosis and treatment of seriously bleeding trauma patients with TIC is presented: (i) AWMF S3 guideline 'Polytrauma/Seriously Injured Patient Treatment' under the auspices of the German Society for Trauma Surgery; (ii) guideline of the European Society of Anesthesiology and Intensive Care (ESAIC) on the management of perioperative bleeding; and (iii) European guideline on the management of major bleeding and coagulopathy after trauma in its 6th edition (EU-Trauma). SUMMARY Treatment of trauma-related bleeding begins at the scene with local compression, use of tourniquets and pelvic binders and rapid transport to a certified trauma centre. After arrival at the hospital, measures to record, monitor and support coagulation function should be initiated immediately. Surgical bleeding control is carried out according to 'damage control' principles. Modern coagulation management includes individualized treatment based on target values derived from point-of-care viscoelastic test procedures.

Effects of Transport to Trauma Centers on Survival Outcomes Among Severe Trauma Patients in Korea: Nationwide Age-Stratified Analysis. J Korean Med Sci 2024; 39:e60. [PMID: 38374629 PMCID: PMC10876434 DOI: 10.3346/jkms.2024.39.e60] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/21/2023] [Accepted: 12/14/2023] [Indexed: 02/21/2024] Open
Abstract
BACKGROUND Previous studies showed that the prognosis for severe trauma patients is better after transport to trauma centers compared to non-trauma centers. However, the benefit from transport to trauma centers may differ according to age group. The aim of this study was to compare the effects of transport to trauma centers on survival outcomes in different age groups among severe trauma patients in Korea. METHODS Cross-sectional study using Korean national emergency medical service (EMS) based severe trauma registry in 2018-2019 was conducted. EMS-treated trauma patients whose injury severity score was above or equal to 16, and who were not out-of-hospital cardiac arrest or death on arrival were included. Patients were classified into 3 groups: pediatrics (age < 19), working age (age 19-65), and elderly (age > 65). The primary outcome was in-hospital mortality. Multivariable logistic regression analysis was conducted to evaluate the effect of trauma center transport on outcome after adjusting of age, sex, comorbidity, mechanism of injury, Revised Trauma Score, and Injury Severity Score. All analysis was stratified according to the age group, and subgroup analysis for traumatic brain injury was also conducted. RESULTS Overall, total of 10,511 patients were included in the study, and the number of patients in each age group were 488 in pediatrics, 6,812 in working age, and 3,211 in elderly, respectively. The adjusted odds ratio (95% confidence interval [CI]) of trauma center transport on in-hospital mortality from were 0.76 (95% CI, 0.43-1.32) in pediatrics, 0.78 (95% CI, 0.68-0.90) in working age, 0.71(95% CI, 0.60-0.85) in elderly, respectively. In subgroup analysis of traumatic brain injury, the benefit from trauma center transport was observed only in elderly group. CONCLUSION We found out trauma centers showed better clinical outcomes for adult and elderly groups, excluding the pediatric group than non-trauma centers. Further research is warranted to evaluate and develop the response system for pediatric severe trauma patients in Korea.

Abstract
The institution of massive transfusion protocols (MTPs) has improved the timely delivery of large quantities of blood products and improves patient outcomes. In recent years, the cost of blood products has increased, compounded by significant blood product shortages. There is practical need for identification of a transfusion volume in trauma patients that is associated with increased mortality, or a threshold after which additional transfusion is futile and associated with nonsurvivability. This transfusion threshold is often described in the setting of an ultramassive transfusion (UMT). There are few studies defining what constitutes amount or outcomes associated with such large volume transfusion. The purpose of this narrative review is to provide an analysis of existing literature examining the effects of UMT on outcomes including survival in adult trauma patients and to determine whether there is a threshold transfusion limit after which mortality is inevitable. Fourteen studies were included in this review. The data examining the utility of UMT in trauma are of poor quality, and with the variability inherent in trauma patients, and the surgeons caring for them, no universally accepted cutoff for transfusion exists. Not surprisingly, there is a trend toward increasing mortality with increasing transfusions. The decision to continue transfusing is multifactorial and must be individualized, taking into consideration patient characteristics, institution factors, blood bank supply, and most importantly, constant reevaluation of the need for ongoing transfusion rather than blind continuous transfusion until the heart stops.

Understanding Regional Trauma Centers and managing a trauma care system in South Korea: a systematic review. Ann Surg Treat Res 2023; 104:61-70. [PMID: 36816735 PMCID: PMC9929433 DOI: 10.4174/astr.2023.104.2.61] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2022] [Revised: 11/21/2022] [Accepted: 12/06/2022] [Indexed: 02/10/2023] Open
Abstract
The Korean government initiated a plan to designate and establish Regional Trauma Centers to reduce the preventable trauma death rate to <20% so as to be on par with advanced countries by 2020. This initiative was undertaken because the reported preventable trauma death rate was close to 40% in South Korea from 1997 to 2009. This review aimed to provide an overview of these Regional Trauma Centers and discuss further development of the trauma care system to assess its performance. As of September 2021, 15 Regional Trauma Centers had been established through a metropolitan-based designation process. Each center has been equipped with Level-I facilities. These Regional Trauma Centers have had 2 positive effects; namely, an increase in the number of severely injured patients attending these centers and a decrease in the national preventable trauma death rate from 30.5% in 2015 to 19.9% in 2017. The establishment of Regional Trauma Centers can lead to improved performance, maximal efficiency, and reduction of preventable deaths in trauma patients. They can also play a key role in prehospital triage and transportation in the trauma care system.

A Cohort Study in Intensive Care Units: Health Decisions Related to Blood Transfusion during the COVID-19 Pandemic. J Clin Med 2022; 11:jcm11154396. [PMID: 35956012 PMCID: PMC9368991 DOI: 10.3390/jcm11154396] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2022] [Revised: 07/05/2022] [Accepted: 07/26/2022] [Indexed: 02/04/2023] Open
Abstract
Critically ill polytrauma patients with hemorrhage require a rapid assessment to initiate hemostatic resuscitation in the shortest possible time with the activation of a massive transfusion or a critical hemorrhage management protocol. The hospital reality experienced during the COVID-19 pandemic in all countries was critical, as it was in Spain; according to the data published daily by the Ministry of Health on its website, during the period of this study, the occupancy rate of intensive care units (ICUs) by patients diagnosed with the novel coronavirus disease (COVID-19) rose to 23.09% in Spain, even reaching 45.23% at the end of January 2021. We aimed to analyze the changes observed during the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic period regarding the effectiveness of Spanish ICUs in terms of mortality reduction. We present a cross-sectional study that compares two cohorts of patients admitted to ICUs across all autonomous communities of Spain with a diagnosis of polytrauma. Results: Only age was slightly higher at admission during the first wave of the pandemic (47.74 ± 18.65 vs. 41.42 ± 18.82 years, p = 0.014). The transfusion rate during the pandemic increased by 10.4% compared to the previous stage (p = 0.058). Regarding hemostatic components, the use of tranexamic acid increased from 1.8% to 10.7% and fibrinogen concentrates from 0.9% to 1.9%. In the case of prothrombin complex concentrates, although there was a slight increase in their use, there were no significant differences during the pandemic compared to the previous period. Conclusion: Mortality showed no difference before and during the pandemic, despite the observed change in the transfusion policy. In summary, the immediate and global implementation of patient blood management (PBM) based on clinical transfusion algorithms should be mandatory in all hospitals in our country.

Impact of establishing a level-1 trauma center for lower extremity trauma: a 4-year experience. BMC Emerg Med 2022; 22:123. [PMID: 35799105 PMCID: PMC9264558 DOI: 10.1186/s12873-022-00682-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2021] [Accepted: 06/13/2022] [Indexed: 11/29/2022] Open
Abstract
Purpose A multidisciplinary approach is essential for trauma patients’ treatment, particularly for cases with open lower extremity fractures, which are considered major traumas requiring a comprehensive approach. Recently, the social demand for severe-trauma centers has increased. This study analyzed the clinical impact of establishing a trauma center for the treatment of open lower extremity fractures. Methods A retrospective chart review was conducted for trauma patients admitted to our hospital. Patients were classified into two groups: before (January 2014–December 2015, 178 patients) and after establishment of a Level-1 trauma center (January 2017–December 2018, 125 patients). We included patients with open fracture below the knee level and Gustilo type II/III, but excluded those with life-threatening trauma that affected the treatment choice. Results Total 273 patient were included in this study, initial infection was significantly more common and external fixator application significantly less in post-center establishment group. The time to emergency operation decreased significantly from 13.89 ± 17.48 to 11.65 ± 19.33 h post-center setup. By multivariate analysis, the decreased primary amputation and increased limb salvage was attributed to establishment of the trauma center. Conclusion With the establishment of the Level-1 trauma center, limbs of patients with open lower extremity fractures could be salvaged, and the need for primary amputation was decreased. Early control of initial open wound infection and minimizing external fixator use allowed early soft tissue reconstruction. The existence of the center ensured a shorter interval to emergency operation and facilitated interdepartmental cooperation, which promoted active limb salvage and contributed to patients’ quality of life.

Abstract
OBJECTIVES Children have a larger reserve for traumatic hemorrhagic shock, requiring a score that uses physiologic variables other than hypotension. Recently, the BIG score comprising admission base deficit, international normalized ratio, and the Glasgow Coma Scale has been reported to predict traumatic mortality. We aimed to validate the performance of the BIG score in mortality prediction of normotensive children with trauma. METHODS We reviewed 1046 injured children (<18 years) who visited a Korean academic hospital from 2010 to 2018, excluding those with age-adjusted hypotension. In-hospital mortality, the BIG score and its predicted mortality, Revised Trauma Score, and Pediatric Trauma Score were calculated. We compared areas under the curve (AUCs) for in-hospital mortality of the 3 scores and did in-hospital and BIG-predicted mortalities. RESULTS Of the 1046 children, 554 were enrolled with a 4.9% in-hospital mortality rate. The median BIG score was higher in the nonsurvivors (6.4 [interquartile range, 4.4-9.2] vs 20.1 [16.5-24.8]; P < 0.001). The AUC of the BIG score was 0.94 (95% confidence interval [CI], 0.92-0.96), which was higher than that of Pediatric Trauma Score (0.87 [95% CI, 0.84-0.90]; P < 0.001). The AUC of the BIG score tended to be higher than that of Revised Trauma Score without statistical significance (0.90 [95% CI, 0.87-0.92]; P = 0.130). We noted a parallel between in-hospital and BIG-predicted mortalities. The hemorrhage-related nonsurvivors showed higher median base deficit and BIG score than did the isolated traumatic brain injury-related ones. CONCLUSIONS The BIG score can predict mortality with excellent accuracy in normotensive children with trauma.

Infrastructure, logistics and clinical practice management of acute trauma hemorrhage and coagulopathy: a survey across German trauma centers. Eur J Trauma Emerg Surg 2021; 48:4461-4472. [PMID: 34564733 DOI: 10.1007/s00068-021-01788-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2021] [Accepted: 09/16/2021] [Indexed: 10/20/2022]
Abstract
PURPOSE Early detection and management of acute trauma hemorrhage and coagulopathy have been associated with improved outcomes, but local infrastructure, logistics and clinical strategies may differ. METHODS To assess local differences in infrastructure, logistics and clinical management of acute trauma hemorrhage and coagulopathy we have conducted a web-based survey amongst clinicians working in DGU®-certified supraregional, regional and local trauma centers. RESULTS 137/1875 respondents completed the questionnaire yielding a response rate of 7.3%. The majority specified to work as head of department or senior consultant (95%) in trauma/orthopedic surgery (80%) of supraregional (38%), regional (34%) or local (27%) trauma centers. Conventional coagulation assays are most frequently used to monitor bleeding trauma patients. Only half of the respondents (53%) rely on extended coagulation tests, e.g. viscoelastic hemostatic assays. Tests to assess preinjury use of direct oral anticoagulants and platelet inhibitors are still not widely available and vary according to level of care. Conventional blood products are widely available but there remain differences between trauma centers of different level of care to access other hemostatic therapies, e.g. coagulation factor concentrates. Trauma centers of higher level of care are more likely to implement treatment protocols. CONCLUSION This survey confirms still existing differences in infrastructure, logistics and clinical practice management for the detection of acute trauma hemorrhage and coagulopathy amongst DGU®-certified supraregional, regional and local trauma centers. Further work is recommended to locally implement diagnostics, therapies and treatment algorithms compliant to current guidelines to ensure the best possible outcomes in bleeding trauma patients.

Abstract
OBJECTIVE The aim of this study was to identify the effects of recent innovations in trauma major hemorrhage management on outcome and transfusion practice, and to determine the contemporary timings and patterns of death. BACKGROUND The last 10 years have seen a research-led change in hemorrhage management to damage control resuscitation (DCR), focused on the prevention and treatment of trauma-induced coagulopathy. METHODS A 10-year retrospective analysis of prospectively collected data of trauma patients who activated the Major Trauma Centre's major hemorrhage protocol (MHP) and received at least 1 unit of red blood cell transfusions (RBC). RESULTS A total of 1169 trauma patients activated the MHP and received at least 1 unit of RBC, with similar injury and admission physiology characteristics over the decade. Overall mortality declined from 45% in 2008 to 27% in 2017, whereas median RBC transfusion rates dropped from 12 to 4 units (massive transfusion rates from 68% to 24%). The proportion of deaths within 24 hours halved (33%-16%), principally with a fall in mortality between 3 and 24 hours (30%-6%). Survivors are now more likely to be discharged to their own home (57%-73%). Exsanguination is still the principal cause of early deaths, and the mortality associated with massive transfusion remains high (48%). Late deaths are now split between those due to traumatic brain injury (52%) and multiple organ dysfunction (45%). CONCLUSIONS There have been remarkable reductions in mortality after major trauma hemorrhage in recent years. Mortality rates continue to be high and there remain important opportunities for further improvements in these patients.

The European Perspective on the Management of Acute Major Hemorrhage and Coagulopathy after Trauma: Summary of the 2019 Updated European Guideline. J Clin Med 2021; 10:jcm10020362. [PMID: 33478011 PMCID: PMC7835990 DOI: 10.3390/jcm10020362] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2020] [Revised: 12/09/2020] [Accepted: 12/14/2020] [Indexed: 12/16/2022] Open
Abstract
Non-controlled hemorrhage with accompanying trauma-induced coagulopathy (TIC) remains the most common cause of preventable death after multiple injury. Rapid identification followed by aggressive treatment is the key for improved outcomes. Treatment of trauma hemorrhage begins at the scene, with manual compression, the use of tourniquets and (non) commercial pelvic slings, and rapid transfer to an adequate trauma center. Upon hospital admission, coagulation monitoring and support are to be initiated immediately. Bleeding is controlled surgically following damage control principles. Modern coagulation management includes goal-oriented, individualized therapies, guided by point-of-care viscoelastic assays. Idarucizumab can be used as an antidote to the thrombin inhibitor dabigatran, andexanet alpha as an antidote to factor Xa inhibitors. This review summarizes the key recommendations of the 2019 updated European guideline on the management of major bleeding and coagulopathy following trauma. These evidence-based recommendations may form the backbone of algorithms adapted to local logistics and infrastructure.

Abstract
BACKGROUND Trauma mortality review is the first step in assessing the quality of the trauma treatment system and provides an important basis for establishing a regional inclusive trauma system. This study aimed to obtain a reliable measure of the preventable trauma death rate in a single province in Korea. METHODS From January to December 2017, a total of 500 sample cases of trauma-related deaths from 64 hospitals in Gyeonggi Province were included. All cases were evaluated for preventability and opportunities for improvement using a multidisciplinary panel review approach. RESULTS Overall, 337 cases were included in the calculation for the preventable trauma death rate. The preventable trauma death rate was estimated at 17.0%. The odds ratio was 3.97 folds higher for those who arrived within "1-3 hours" than those who arrived within "1 hour." When the final treatment institution was not a regional trauma center, the odds ratio was 2.39 folds higher than that of a regional trauma center. The most significant stage of preventable trauma death was the hospital stage, during which 86.7% of the cases occurred, of which only 10.3% occurred in the regional trauma center, whereas preventable trauma death was more of a problem at emergency medical institutions. CONCLUSION The preventable trauma death rate was slightly lower in this study than in previous studies, although several problems were noted during inter-hospital transfer; in the hospital stage, more problems were noted at emergency medical care facilities than at regional trauma centers. Further, several opportunities for improvements were discovered regarding bleeding control.

The effect of massive transfusion protocol implementation on the survival of trauma patients: a systematic review and meta-analysis. BLOOD TRANSFUSION = TRASFUSIONE DEL SANGUE 2020; 18:434-445. [PMID: 32955420 DOI: 10.2450/2020.0065-20] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Subscribe] [Scholar Register] [Received: 03/15/2020] [Accepted: 06/22/2020] [Indexed: 02/03/2023]
Abstract
BACKGROUND Massive transfusion protocol (MTP) has been widely adopted for the care of bleeding trauma patients but its actual effectiveness is unclear. An earlier meta-analysis on the implementation of MTP for injured patients from 1990 to 2013 reported that only 2 out of 8 studies showed statistical improvement in survival. This study aimed to conduct an updated systematic review and meta-analysis to evaluate the effect of implementing an MTP on the mortality of trauma patients. MATERIALS AND METHODS MEDLINE, PubMed, Cochrane Library and Google scholar databases were systematically searched for relevant studies published from 1st January 2008 to 30th September 2019 using a combination of keywords and additional manual searching of reference lists. Inclusion criteria were: original study in English, study population including trauma patients, and comparison of mortality outcomes before and after institutional implementation of an MTP. Primary outcomes were 24-hour, 30-day, and overall mortality. RESULTS Fourteen studies met inclusion criteria, analysing outcomes from 3,201 trauma patients. There was a wide range of outcomes, patient populations, and process indicators utilised by the different authors. MTP significantly reduced the overall mortality for trauma patients (OR 0.71 [0.56-0.90]). No significant reduction was seen in either the 24-hour mortality (OR 0.81 [0.57-1.14]) or the 30-day mortality (OR 0.73 [0.46-1.16]). However, when mortality timing was unspecified, mortality was statistically reduced (OR 0.69 [0.55-0.86]). DISCUSSION The present study found a significant reduction in mortality following MTP implementation and thus it should be recommended to all institutions managing acutely injured patients. To better identify which elements of an MTP contribute to this effect, we encourage the use of standard nomenclature, indicators, protocols and patient populations in all future MTP studies.

Abstract
BACKGROUND Uncontrolled bleeding with trauma-induced coagulopathy (TIC) is still the most common avoidable cause of death in multiple trauma. The aging of the population has led to an increasing number of bleeding trauma patients with pre-existing anticoagulation. Such patients are not treated uniformly, even in major trauma centers. METHODS This review is based on a selective search of the literature (Medline/PubMed, Cochrane Reviews) and summarizes current treatment recommendations, including those of the newly revised European trauma guidelines. RESULTS The treatment of traumatic hemorrhage begins at the site of the accident, with compression, tourniquets, pelvic binders, and rapid transport to a certified trauma center. The early use of tourniquets was shown to lessen the trans- fusion requirement (packed red blood cells: 2.0 ± 0.1 vs. 9.3 ± 0.6; p < 0.001; fresh frozen plasma concentrates: 1.4 ± 0.08 vs. 6.2 ± 0.4; p < 0.001), while external pelvic stabilization was shown to reduce mortality (19.1% vs. 33.3%). Upon the patient's arrival in the hospital, steps are taken to measure, monitor, and support clotting function. Bleeding is controlled surgically according to the principles of damage control. Modern clotting management consists of goal-oriented, individualized therapy, including the use of point-of-care viscoelastic test procedures. Idarucizumab can be used as an antidote to the thrombin inhibitor dabigatran, andexanet alpha as an antidote to factor Xa inhibitors. CONCLUSION The evidence-based treatment of patients with hemorrhage from severe trauma, in accordance with the existing guidelines, can improve the clinical outcome. Corresponding algorithms, adapted to local logistics and infrastructure, must be developed and implemented.

Abstract
BACKGROUND Damage control laparotomy (DCL) is a lifesaving technique to minimize the lethal triad of coagulopathy, hypothermia, and acidosis. The government has nominated and supported our center as one of the regional trauma centers of South Korea since 2014. This study aimed to investigate the improving outcomes of patients undergoing DCL before and after the establishment of the trauma center. METHOD The period from January 2011 to December 2017 was divided into pre-trauma center (pre-TC) (2011-2013) and trauma center (TC) (2014-2017) periods. Multivariable logistic regression was performed to identify the risk factors and risk-adjusted cumulative sum (RA-CUSUM), and graphs were used to monitor the change in mortality. RESULT Of the 485 patients who underwent trauma laparotomy, DCL was performed for 119 patients (24.5%). The operation time (99 vs. 80 min, p = 0.022), time from admission to operation (125 vs. 112 min, p = 0.010), time from admission to first treatment (119 vs. 99 min, p = 0.004), and time from admission to first transfusion (70 vs. 52 min, p = 0.009) were significantly shortened in the TC period. The ratio of plasma to packed red blood cells in massive transfusions (≥PRBCs 10 units within the first 24 h) was significantly increased in the TC period (0.56 vs. 0.72, p = 0.004). RA-CUSUM curves revealed that the risk-adjusted 30-day mortality improved and then plateaued in the TC period. CONCLUSION After the implementation of a trauma center, more prompt intervention and damage control resuscitation could be achieved. Moreover, risk-adjusted mortality of DCL was improved.

Abstract
BACKGROUND Despite the presence of highly reliable data, studies on packed red blood cells (pRBC):fresh frozen plasma (FFP) ratio suffer from limited sample size and the presence of survivor bias. We sought to study the association between FFP:pRBC and early mortality in the hemorrhaging trauma patient. STUDY DESIGN This was a retrospective nationwide cohort that included all TQIP participating hospitals (2013 to 2016). We included all trauma patients who were transfused ≥10 pRBCs and ≥1 FFP within 24 hours. We excluded transferred patients and those who died in the emergency department or had missing/inaccurate transfusion data. Patients were assigned to 7 FFP:pRBC cohorts (range 1:1 to 1:6, and 1:6+) only if the ratio was similar at 4 and 24 hours and, to avoid survival bias, were excluded otherwise. Multivariable analyses correcting for all available confounders (age, demographics, comorbidities, vital signs, Injury Severity Score [ISS] and mechanism, procedures performed) were derived to study the independent relationship between FFP:pRBC and 24-hour mortality. RESULTS Of 1,002,595 patients, 4,427 patients were included. Mean age was 41 years, 79% were males, 61% had blunt trauma, and median ISS was 29. Most patients were transfused in a 1:1, 1:2, or 1:3 ratio (31%, 41%, and 11%, respectively); mortality ranged between 28% for 1:1 and 62% for 1:4. In multivariable analyses, the odds of mortality independently and incrementally increased to 1.23 (95% CI 1.02 to 1.48) for a 1:2 ratio, 2.11 (95% CI 1.42 to 3.13) for 1:4, and as high as 4.11 (95% CI 2.31 to 7.31) for 1:5 (all p < 0.05). CONCLUSIONS A 1:1 FFP:pRBC ratio is associated with the lowest mortality in the hemorrhaging trauma patient, and mortality increases with decreasing ratios.
