Prehospital Antibiotic Administration for Suspected Open Fractures: Joint COT/OTA/ACEP/NAEMSP/NAEMT Position Statement. PREHOSP EMERG CARE 2024:1-13. [PMID: 39356234 DOI: 10.1080/10903127.2024.2409380] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2024] [Revised: 08/29/2024] [Accepted: 09/15/2024] [Indexed: 10/03/2024]
Abstract
One of the primary concerns associated with open fractures is the development of a fracture-related infection (FRI). To minimize the risk of developing an FRI and subsequent morbidity, prophylactic antibiotics should be administered to patients with open fractures as soon as possible. While the antibiotic recommendations for severe open fractures are somewhat debatable, the use of a cephalosporin remains a mainstay of prophylactic treatment. Though administration of prehospital antibiotics does represent an expansion of EMS responsibilities, there have been several other treatment expansions in the prehospital setting, such as the administration of tranexamic acid and the application of pelvic binders. The administration of antibiotics, specifically cefazolin, is inexpensive, technically simple, and does not require special storage. The following recommendations are supported by and represent consensus of the COT, OTA, ACEP, NAEMSP and NAEMT with regards to prehospital antibiotic prophylaxis for suspected fractures:In a responsive patient with no history of penicillin or cephalosporin allergy, the administration by EMS of a 1st generation cephalosporin should be performed after the management of life threats. This intervention should not delay transport.In an obtunded patient, the administration by EMS of a 1st generation cephalosporin should be performed after the management of life-threats. This intervention should not delay transport.In a responsive patient with a documented penicillin allergy, the administration by EMS of a 1st generation cephalosporin should be performed with close monitoring after the management of life-threats. This intervention should not delay transport.

Abstract
INTRODUCTION Tranexamic acid (TXA) is a potent antifibrinolytic drug that inhibits the activation of plasmin by plasminogen. While not a new medication, TXA has quickly gained traction across a variety of surgical subspecialties to prevent and treat bleeding. Knowledge on the use of this drug is essential for the modern surgeon to continue to provide excellent care to their patients. METHODS A comprehensive review of the PubMed database was conducted of articles published within the last 10 y (2014-2024) relating to TXA and its use in various surgical subspecialties. Seminal studies regarding the use of TXA older than 10 y were included from the author's archives. RESULTS Indications for TXA are not limited to trauma alone, and TXA is utilized across a variety of surgical subspecialties from neurosurgery to hepatic surgery to control hemorrhage. Overall, TXA is well tolerated with common dose-dependent adverse effects, including headache, nasal symptoms, dizziness, nausea, diarrhea, and fatigue. More severe adverse events are rare and easily mitigated by not exceeding a dose of 50 mg/kg. CONCLUSIONS The administration of TXA as an adjunct to treat trauma saves lives. The ability of TXA to induce seizures is dose dependent with identifiable risk factors, making this serious adverse effect predictable. As for the potential for TXA to cause thrombotic events, uncertainty remains. If this association is proven to be real, the risk will likely be small, since the use of TXA is still advantageous in most situations because of its efficacy for a more common concern, bleeding.

Abstract
INTRODUCTION To improve rural and austere trauma care, hospital-based testing performed at the point of injury may shorten the time lapsed from injury to intervention. This study aimed to evaluate the use of the TEG6s device (Haemonetics(R), Clinton, PA) in a rotary wing aircraft. Prior attempts suffered from limitation related to lack of vibration mitigation. METHODS This was an investigator-initiated, industry-supported study. Haemonetics provided a TEG6s analyzer. The device underwent a standard validation. It was secured in place on the aircraft using shipping foam for vibration mitigation. Donors provided two tubes of sample blood in one sitting. Paired studies were performed on the aircraft during level flight and in the hospital, using the Global Hemostasis with Lysis Cartridge(Haemonetics (R), Clinton, PA). Both normal and presumed pathologic samples were tested in separate phases. Paired t tests were performed. RESULTS For normal donors, the mean R for laboratory compared with the aircraft was 6.2 minutes versus 7.2 minutes ( p = 0.025). The mean ± SD Citrated Rapid TEG Maximum Amplitude (CRT MA) was 59.3 ± 5.6 mm and 55.9 ± 7.3 mm ( p < 0.001) for laboratory and aircraft ( p < 0.001). Among normal donors, R was within normal range for 17 of 18 laboratory tests and 18 of 18 aircraft tests ( p > 0.99). During the testing of pathologic samples, the mean R time was 14.8 minutes for laboratory samples and 12.6 minutes for aircraft ( p = 0.02). Aircraft samples were classified as abnormal in 78% of samples; this was not significantly different than laboratory samples ( p = 0.5). CONCLUSION The use of the TEG6s for inflight viscoelastic testing appears promising. While statistically significant differences are seen in some results, these values are not considered clinically significant. Classifying samples as normal or abnormal demonstrated a higher correlation. Future studies should focus on longer flight times to evaluate for LY30, takeoff, and landing effects. Overall, this study suggests that TEG6s can be used in a prehospital environment, and further study is warranted. LEVEL OF EVIDENCE Diagnostic Tests or Criteria; Level III.

Abstract
Tranexamic acid (TXA) is a synthetic antifibrinolytic agent that has been used for several decades to reduce blood loss during surgery and after trauma. TXA was traditionally used to reduce bleeding in various clinical settings such as menorrhagia, hemophilia, or other bleeding disorder. Numerous studies have demonstrated the efficacy of TXA in reducing blood loss and the need for transfusions. Interest in the potential applications of TXA beyond its traditional use has been growing recently, with studies investigating the use of TXA in postpartum hemorrhage, cardiac surgery, trauma, neurosurgery, and orthopedic surgery. Despite its widespread use and expanding indications, data regarding the safe and appropriate use of TXA is lacking. Recent clinical trials have found various potential risks and limitations in the long-term benefits of TXA. This narrative review summarizes the clinical applications and limitations of TXA.

Abstract
STUDY OBJECTIVES Tranexamic acid (TXA) is an antifibrinolytic that is widely used to reduce surgical bleeding. However, TXA occasionally causes seizures and the risk might be especially great after neurosurgery. We therefore tested the hypothesis that TXA does not meaningfully increase the risk of postoperative seizures within 7 days after intracranial tumor resections. DESIGN Randomized, double-blind, placebo-controlled, non-inferiority trial. SETTING Beijing Tiantan Hospital, Capital Medical University. PATIENTS 600 patients undergoing supratentorial meningioma resection were included from October 2020 to August 2022. INTERVENTIONS Patients were randomly assigned to a single dose of 20 mg/kg of TXA after induction (n = 300) or to the same volume of normal saline (n = 300). MEASUREMENT The primary outcome was postoperative seizures occurring within 7 days after surgery, analyzed in both the intention-to-treat and per-protocol populations. Non-inferiority was defined by an upper limit of the 95% confidence interval for the absolute difference being <5.5%. Secondary outcomes included incidence of non-epileptic complication within 7 days, changes in hemoglobin concentration, estimated intraoperative blood loss. Post hoc analyses included the types and timing of seizures, oozing assessment, and a sensitivity analysis for the primary outcome in patients with pathologic diagnosis of meningioma. MAIN RESULTS All 600 enrolled patients adhered to the protocol and completed the follow-up for the primary outcome. Postoperative seizures occurred in 11 of 300 (3.7%) of patients randomized to normal saline and 13 of 300 (4.3%) patients assigned to tranexamic acid (mean risk difference, 0.7%; 1-sided 97.5% CI, -∞ to 4.3%; P = 0.001 for noninferiority). No significant differences were observed in any secondary outcome. Post hoc analysis indicated similar amounts of oozing, calculated blood loss, recurrent seizures, and timing of seizures. CONCLUSION Among patients having supratentorial meningioma resection, a single intraoperative dose of TXA did not significantly reduce bleeding and was non-inferior with respect to postoperative seizures after surgery. REGISTRY INFORMATION This trial was registered at clinicaltrials.gov (NCT04595786) on October 22, 2020, by Dr.Yuming Peng.

Abstract
Tranexamic acid (TXA) is an antifibrinolytic drug that reduces bleeding by inhibiting plasminogen activation and fibrin clot degradation. Its role in prehospital trauma management remains unclear. This article aims to systematically review the current evidence on the effect of prehospital TXA administration on mortality in adult and pediatric trauma patients. A literature search was conducted of PubMed, Web of Science, Scopus, and Cochrane databases from March 2023 to August 2023 for studies evaluating the impact of prehospital TXA use on trauma mortality. Inclusion criteria were articles published in the English language in the past 20 years focusing on clinical outcomes of prehospital TXA administration. Data on all-cause mortality, thromboembolic events, and time to TXA administration were extracted. In adult trauma, prehospital TXA appears to reduce early all-cause mortality when given within three hours of injury without increasing thromboembolic risks. Some studies found decreased delayed mortality, while others found no difference. In pediatric trauma, preliminary evidence suggests TXA may lower in-hospital mortality in hemodynamically unstable patients, though higher doses may increase seizure risk. Early prehospital administration of TXA within three hours of adult trauma may reduce mortality through improved hemorrhage control. Potential benefits in pediatric trauma warrant further investigation, balancing efficacy against safety risks such as seizures from high doses. Well-designed randomized trials are needed to validate optimal TXA dosing strategies across age groups and injury severity levels.

Abstract
Background Prehospital tranexamic acid (TXA) may hold substantial benefits for trauma patients; however, the data underlying its efficacy and safety is scarce. Methods We searched PubMed, Embase, the Cochrane Library, and ClinicalTrials.gov from inception to July 2023 for all randomized controlled trials (RCTs) investigating prehospital TXA in trauma patients as compared to placebo or standard care without TXA. Data were pooled under a random-effects model using RevMan 5.4 with risk ratio (RR) and mean difference (MD) as the effect measures. Results A total of three RCTs were included in this review. Regarding the primary outcomes, prehospital TXA reduced the risk of 1-month mortality (RR 0.82, 95% CI 0.69-0.97) but did not increase survival with a favorable functional outcome at 6 months (RR 1.00, 95% CI 0.93-1.09). Prehospital TXA also reduced the risk of 24-h mortality but did not affect the risk of mortality due to bleeding and traumatic brain injury. There was no significant difference between the TXA and control groups in the incidence of RBC transfusion, and the number of ventilator- and ICU-free days. Prehospital TXA did not increase the risk of adverse events except for a small increase in the incidence of infections. Conclusion Prehospital TXA is useful in reducing mortality in trauma patients without a notable increase in the risk of adverse events. However, there was no effect on the 6-month favorable functional status. Further large-scale trials are required to validate the aforementioned findings. Systematic review registration PROSPERO (CRD42023451759).

Abstract
Prehospital resuscitation is a dynamic field now being energized by new technologies and a shift in thinking regarding intravascular resuscitation. Growing evidence discourages use of intravenous (IV) crystalloid and colloid solutions in trauma, whereas blood products, particularly whole blood, are becoming preferred. Although randomized clinical trials validating definitive resuscitative protocols are still lacking, most preclinical and clinical indicators support this approach. In addition, emerging technologies such as external and endovascular hemorrhage control devices and extracorporeal perfusion are now being used routinely, even in the prehospital setting in many countries, generating new lines of emerging investigations for trauma specialists.

Abstract
There are situations in the pre-hospital setting where gaining intravenous or intraosseous access is impossible or delayed. This can delay the administration of tranexamic acid to bleeding trauma patients, which may reduce its effectiveness. We sought to investigate whether some patients would benefit from early administration of tranexamic acid via the intramuscular route. Relevant observational and interventional studies were identified and summarised using a BestBET format. The current evidence supports clinicians considering intramuscular tranexamic acid in trauma patients at risk of haemorrhage when there may be significant delay in administration via intravenous or intraosseous routes.

Abstract
During trauma and surgery, bleeding is a major concern. One of the crucial strategies for hemostasis is the use of biological hemostatic material. Herein, we reported an amino acid-based hydrogel FmocF-ADP hydrogel, which consisted of N-[(9H-fluoren-9-ylmethoxy) carbonyl]-3-phenyl-L-alanine (FmocF) and adenosine diphosphate (ADP) sodium solution. The hydrogel was created by FmocF self-assembling to nanofiber in ADP sodium solution and then cross-linking to hydrogel. FmocF-ADP hydrogel showed good in vitro coagulation activity as measured by whole blood clotting assays, platelet clotting assays, platelet activation assays, and platelet adhesion assays. Further, it was noted to reveal an exceptional in vivo hemostatic effect in a mouse liver bleeding model. Together with the previous report of the good biocompatibility and antimicrobial activity of FmocF hydrogel, our study would extend the biomedical application of FmocF hydrogel. In conclusion, the present study would provide a constructive strategy for the development of new antimicrobial and hemostatic materials or develop a potential hemostatic material.

Abstract
Tranexamic acid (TXA) is a common haemorrhage control agent in both emergency department (ED) settings and intra-operatively. While efficacy and potential harms are well-studied, there are no overviews of reviews completed on TXA efficacy in the ED setting. We set out to provide an overview of systematic reviews on TXA efficacy in trauma, gastrointestinal bleeding, and subarachnoid haemorrhage in the ED setting, with outcomes including short and long-term mortality, thromboembolic (TE) events, and whether bleeding continued. Our review is guided by the PRIOR statement. We searched Pubmed, Medline, and EMBASE using broad search terms for systematic reviews, and calculated pooled relative-risk ratios using random and fixed-effects modelling from these studies. A risk-of-bias assessment was also completed for each review. We identified 13 systematic reviews for inclusion, with a variety of different outcomes. We identified improvements in 24-h mortality for trauma (RR 0.88, 95% CI 0.84-0.92) and gastrointestinal bleeds (RR 0.30, 95% CI 0.23-0.39), and decreased long-term gastrointestinal bleed mortality (RR 0.57, 95% CI 0.48-0.69). We also identified an increase in TE risk in gastrointestinal bleeding scenarios (RR 1.45, 95% CI 1.09-1.94), but no other clinical scenarios. TXA is effective in reducing mortality following trauma and gastrointestinal bleeds, however, there is limited evidence at this time to support TXA administration in the context of subarachnoid haemorrhage. TE risk is elevated when used in gastrointestinal bleeds. Selective use in high-risk patients may be warranted. TXA should strongly be considered in management in ED and prehospital settings.

Abstract
PURPOSE OF REVIEW Transfusion of blood products is lifesaving in the trauma ICU. Intensivists must be familiar with contemporary literature to develop the optimal transfusion strategy for each patient. RECENT FINDINGS A balanced ratio of red-blood cells to plasma and platelets is associated with improved mortality and has therefore become the standard of care for resuscitation. There is a dose-dependent relationship between units of product transfused and infections. Liquid and freeze-dried plasma are alternatives to fresh frozen plasma that can be administered immediately and may improve coagulation parameters more rapidly, though higher quality research is needed. Trauma induced coagulopathy can occur despite a balanced transfusion, and administration of prothrombin complex concentrate and cryoprecipitate may have a role in preventing this. In addition to balanced ratios, viscoelastic guidance is being increasingly utilized to individualize component transfusion. Alternatively, whole blood can be used, which has become the standard in military practice and is gaining popularity at civilian centers. SUMMARY Hemorrhagic shock is the leading cause of death in trauma. Improved resuscitation strategy has been one of the most important contemporary advancements in trauma care and continues to be a key area of clinical research.

Abstract
Tranexamic acid (TXA) is a potent antifibrinolytic with documented efficacy in reducing blood loss and allogeneic red blood cell transfusion in several clinical settings. With a growing emphasis on patient blood management, TXA has become an integral aspect of perioperative blood conservation strategies. While clinical applications of TXA in the perioperative period are expanding, routine use in select clinical scenarios should be supported by evidence for efficacy. Furthermore, questions regarding optimal dosing without increased risk of adverse events such as thrombosis or seizures should be answered. Therefore, ongoing investigations into TXA utilization in cardiac surgery, obstetrics, acute trauma, orthopedic surgery, neurosurgery, pediatric surgery, and other perioperative settings continue. The aim of this review is to provide an update on the current applications and limitations of TXA use in the perioperative period.

Abstract
Tranexamic acid (TXA) reduces the risk of bleeding trauma death without altering the need for blood transfusion. We examined the effects of TXA on coagulation and fibrinolysis dynamics and the volume of transfusion during the early stage of trauma. This subanalysis of a prospective multicenter study of severe trauma included 276 patients divided into propensity score-matched groups with and without TXA administration. The effects of TXA on coagulation and fibrinolysis markers immediately at (time point 0) and 3 hours after (time point 3) arrival at the emergency department were investigated. The transfusion volume was determined at 24 hours after admission. TXA was administered to the patients within 3 hours (median, 64 minutes) after injury. Significant reductions in fibrin/fibrinogen degradation products and D-dimer levels from time points 0 to 3 in the TXA group compared with the non-TXA group were confirmed, with no marked differences noted in the 24-hour transfusion volumes between the 2 groups. Continuously increased levels of soluble fibrin, a marker of thrombin generation, from time points 0 to 3 and high levels of plasminogen activator inhibitor-1, a marker of inhibition of fibrinolysis, at time point 3 were observed in both groups. TXA inhibited fibrin(ogen)olysis during the early stage of severe trauma, although this was not associated with a reduction in the transfusion volume. Other confounders affecting the dynamics of fibrinolysis and transfusion requirement need to be clarified.

Abstract
Introduction: Hemorrhage is responsible for up to 40% of all traumatic deaths. The seminal CRASH-2 trial demonstrated a reduction in overall mortality following early tranexamic acid (TXA) administration to bleeding trauma patients. Following publication of the trial results, TXA has been incorporated into many prehospital trauma protocols. However, the cost-effectiveness of widespread TXA adoption by EMS is unknown.Objective: To estimate the cost-effectiveness of statewide implementation of a TXA protocol.Methods: The North Carolina Trauma Registry was queried to identify potential TXA patients using the a priori criteria of age ≥18 years, suspected hemorrhage, penetrating or blunt injury, and prehospital blood pressure <90 mmHg and heart rate >110 bpm. Using life tables adjusted for age, sex, and race, and the absolute risk reductions in mortality with early TXA administration reported in the literature, the life-years gained were calculated for each potential life saved. Implementation costs consisted of initial stocking, training, and replacement costs. Projected reduction in hospitalization costs were based on estimates reported in the literature. Economic analyses were conducted from societal and state EMS system perspectives. To assess the robustness of the model, univariate and bivariate sensitivity analyses were performed on selected input variables.Results: Based on the TXA inclusionary criteria, 159 patients could potentially receive TXA per year. In the base-case scenario with a projected absolute mortality reduction of 3%, an additional 4.8 lives per year in NC would be saved, with an estimated 191 total life-years gained. The statewide implementation and operation cost was $305,122 in year 1, and continued operating costs were $6,042 in years 2 and 3, yielding a cost per life saved of $63,967 in year 1 and $1,267 in years 2 and 3. The cost per life-year gained was $1,595 in year 1 and $32 in years 2 and 3. Annual hospitalization costs would potentially be reduced by $1,828,072.Conclusion: Previous studies have demonstrated the clinical effectiveness of early TXA administration to patients with hemorrhage. Our modeling of the financial implications and clinical benefits of implementing a statewide TXA protocol suggests that prehospital TXA is a cost-effective treatment.

Abstract
BACKGROUND Improved outcomes with early tranexamic acid (TXA) following trauma hemorrhagic shock (T/HS) may be related to its antifibrinolytic, as well as anti-inflammatory properties. Previous in vitro studies have shown that early TXA administration protects against T/HS endothelial barrier dysfunction and associated glycocalyx degradation. An intact endothelial glycocalyx may protect against subsequent neutrophil mediated tissue injury. We postulated that early TXA administration would mitigate against glycocalyx damage and resultant neutrophil adherence and transmigration through the endothelial barrier. This was studied in vitro using a microfluidic flow platform. METHODS Human umbilical vein endothelial cell monolayers were subjected to control or shock conditions (hypoxia + epinephrine) followed by administration of TXA 90 minutes or 180 minutes later. RESULTS "Early" TXA administration protected against glycocalyx degradation, biomarkers of increased permeability and the development of a fibrinolytic phenotype. This was associated with decreased neutrophil endothelial adherence and transmigration. There were no differences in low versus high TXA concentrations. The protective effects were only significant with "early" TXA administration. CONCLUSION There was a concentration and temporal effect of TXA administration on endothelial glycocalyx degradation. This was associated with "vascular leakiness" as indexed by the relative ratio of Ang-2/1 and polymorphonuclear neutrophil transmigration. Tranexamic acid if administered in patients with T/HS should be administered "early"; this includes in the prehospital setting.

Abstract
IMPORTANCE Tranexamic acid is widely available and used off-label in patients with bleeding traumatic injury, although the literature does not consistently agree on its efficacy and safety. OBJECTIVE To examine the association of tranexamic acid administration with mortality and thromboembolic events compared with no treatment or with placebo in patients with traumatic injury in the literature. DATA SOURCES On March 23, 2021, PubMed, Embase, and the Cochrane Library were searched for eligible studies published between 1986 and 2021. STUDY SELECTION Randomized clinical trials and observational studies investigating tranexamic acid administration compared with no treatment or placebo among patients with traumatic injury and traumatic brain injury who were 15 years or older were included. Included studies were published in English or German. The electronic search yielded 1546 records, of which 71 were considered for full-text screening. The selection process was performed independently by 2 reviewers. DATA EXTRACTION AND SYNTHESIS The study followed the Cochrane Handbook for Systematic Reviews of Interventions and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Data were extracted by 2 independent reviewers and pooled using the inverse-variance random-effects model. MAIN OUTCOMES AND MEASURES Outcomes were formulated before data collection and included mortality at 24 hours and 28 and 30 days (1 month) as well as the incidence of thromboembolic events and the amount of blood products administered. Owing to missing data, overall mortality was added and the amount of blood products administered was discarded. RESULTS Thirty-one studies with a total of 43 473 patients were included in the systematic review. The meta-analysis demonstrated that administration of tranexamic acid was associated with a significant decrease in 1-month mortality compared with the control cohort (risk ratio, 0.83 [95% CI, 0.71-0.97]; I2 = 35%). The results of meta-analyses for 24-hour and overall mortality and thromboembolic events were heterogeneous and could not be pooled. Further investigations on clinical heterogeneity showed that populations with trauma and trial conditions differed markedly. CONCLUSIONS AND RELEVANCE These findings suggest that tranexamic acid may be beneficial in various patient populations with trauma. However, reasonable concerns about potential thromboembolic events with tranexamic acid remain.

Abstract
OBJECTIVE Tranexamic acid (TXA) has demonstrated a reduction in all-cause mortality in trauma patients with hemorrhage. Administering TXA in the prehospital setting presents unique challenges because the identification of bleeding is based on clinical suspicion without advanced imaging or diagnostic tools. The objective of this study was to examine whether prehospital suspicion of bleeding is validated by in-hospital computed tomographic imaging and examination and to determine if patients received TXA in the absence of hemorrhage. The study was conducted at a level 1 trauma center supported by air medical transport services. METHODS This is a retrospective cohort study examining 88 trauma patients receiving prehospital TXA to treat suspected hemorrhage. Adult trauma patients who received TXA during the study period and were transported to our level 1 trauma center were included. A panel of trauma surgeons reviewed CT imaging and examination findings to retrospectively identify significant hemorrhage. RESULTS Forty-three percent of patients who received TXA during air medical transport did not have confirmed hemorrhage upon arrival. CONCLUSION TXA was given to a significant number of patients who did not have confirmed hemorrhage upon arrival. We recommend that institutions using TXA perform this internal validation to ensure they are accurately identifying hemorrhage in the prehospital setting.

Abstract
INTRODUCTION Growing evidence recommends antifibrinolytic agent tranexamic acid (TXA) to reduce blood loss and transfusions rate in various surgical settings. However, postoperative seizure, as one of the major adverse effects of TXA infusion, has been a concern that restricts its utility in neurosurgery. METHODS AND ANALYSIS This is a randomised, placebo-controlled, non-inferiority trial. Patients with supratentorial meningiomas and deemed suitable for surgical resection will be recruited in the trial. Patients will be randomised to receive either a single administration of 20 mg/kg TXA or a placebo of the same volume with a 1:1 allocation ratio after anaesthesia induction. The primary endpoint is the cumulative incidence of early postoperative seizures within 7 days after craniotomy. Secondary outcomes include the incidence of non-seizure complications, changes of haemoglobin level from baseline, intraoperative blood loss, erythrocyte transfusion volume, Karnofsky Performance Status, all-cause mortality, and length of stay, and total hospitalisation cost. ETHICS AND DISSEMINATION This trial is registered at ClinicalTrial.gov and approved by the Chinese Ethics Committee of Registering Clinical Trials (ChiECRCT20200224). The findings will be disseminated in peer-reviewed journals and presented at national or international conferences relevant to subject fields. TRIAL REGISTRATION NUMBER NCT04595786.

Abstract
BACKGROUND Trauma is a major cause of morbidity and mortality in older adults and will become more common as the population ages. Tranexamic acid (TXA) is a lysine analogue frequently used in the setting of significant trauma with hemorrhage. The aim of this study is to investigate the heterogeneity of treatment effect of TXA as it relates to patient age during trauma care. METHODS We included patients from the CRASH-2 trial who were randomized within 3 h of injury. Patients were stratified into age groups <26 years, 26 to 35 years, 36 to 45 years, 46 to 55 years, and >55 years. Multiple logistic regression models were utilized to evaluate adjusted odds ratios (OR) with 95% confidence intervals (CI) for mortality. Heterogeneity of treatment effect was evaluated using Akaike and Bayesian information criteria to determine the optimum logistic regression model after which a Wald Chi-square test was utilized to evaluate statistical significance. RESULTS On univariate analysis, TXA administration decreased mortality within the <26 years cohort (decrease of 2.1%, 95% CI 0.2 to 4.0), 46 to 55 years cohort (decrease 6.7%, 95% CI 2.7 to 10.7), and >55 years cohort (decrease of 5.3%, 95% CI 0.4 to 10.3). On adjusted analysis, when compared to the 36 to 45 years cohort, the <26 year cohort experienced a decreased mortality (OR 0.72, 95% CI 0.62 to 0.85) whereas the >55 year cohort experienced increased mortality (OR 1.8, 95% CI 1.5 to 2.2). Assessment for heterogeneity of treatment effect of TXA administration between groups approached but did not reach statistical significance (p = 0.11). CONCLUSIONS Mortality related to trauma increases with age, however, there does not appear to be heterogeneity of treatment effect for TXA administration among different age groups.

Abstract
Background Prehospital administration of tranexamic acid (TXA) to injured patients is increasing worldwide. However, optimal TXA dose and need of a second infusion on hospital arrival remain undetermined. We investigated the efficacy and safety of the second in-hospital dose of TXA in injured patients receiving 1 g of TXA in the prehospital setting. We hypothesized that a second in-hospital dose of TXA improves survival of trauma patients. Methods A prospective, double-blind, placebo-controlled randomized, clinical trial included adult trauma patients receiving 1 g of TXA in the prehospital settings. Patients were then blindly randomized to Group I (second 1-g TXA) and Group II (placebo) on hospital arrival. The primary outcome was 24-h (early) and 28-day (late) mortality. Secondary outcomes were thromboembolic events, blood transfusions, hospital length of stay (HLOS) and organs failure (MOF). Results A total of 220 patients were enrolled, 110 in each group. The TXA and placebo groups had a similar early [OR 1.000 (0.062–16.192); p = 0.47] and late mortality [OR 0.476 (95% CI 0.157–1.442), p = 0.18].The cause of death (n = 15) was traumatic brain injury (TBI) in 12 patients and MOF in 3 patients. The need for blood transfusions in the first 24 h, number of transfused blood units, HLOS, thromboembolic events and multiorgan failure were comparable in the TXA and placebo groups. In seriously injured patients (injury severity score > 24), the MTP activation was higher in the placebo group (31.3% vs 11.10%, p = 0.13), whereas pulmonary embolism (6.9% vs 2.9%, p = 0.44) and late mortality (27.6% vs 14.3%, p = 0.17) were higher in the TXA group but did not reach statistical significance. Conclusion The second TXA dose did not change the mortality rate, need for blood transfusion, thromboembolic complications, organ failure and HLOS compared to a single prehospital dose and thus its routine administration should be revisited in larger and multicenter studies.

Effectiveness and Safety of Tranexamic Acid Use in Acute Traumatic Injury in the Prehospital and In-hospital Settings: A Systematic Review and Meta-Analysis of Randomized Controlled Trials. ANNALS OF SURGERY OPEN 2021; 2:e105. [PMID: 37637875 PMCID: PMC10455131 DOI: 10.1097/as9.0000000000000105] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2021] [Accepted: 09/26/2021] [Indexed: 11/26/2022] Open
Abstract
Background and Objectives This systematic review and meta-analysis of randomized controlled trials (RCTs) aims to assess efficacy and safety of tranexamic acid (TXA) use in acute traumatic injuries. Methods PubMed and Cochrane libraries were searched for relevant RCTs published between January 2011 and January 3, 2021. Cohen's Q Test for heterogeneous effects was used to determine the appropriateness of fixed versus random effects models. Results Twenty-two studies met inclusion criteria. Meta-analysis of relative risk of mortality between treatment and placebo groups in the in-hospital, and perioperative settings was not significant. However, the risk of mortality is significantly lower in the treatment versus placebo group when TXA was given as loading dose only. Ten of the 11 studies evaluating perioperative use of TXA included in systematic review found significantly lower blood loss in the treatment compared with placebo groups, but results of meta-analysis showed no significant difference. Results of meta-analysis indicate that the risk of venous thromboembolism (VTE) in the in-hospital treatment group is greater than that of the placebo. In subset analysis of studies using only a single loading dose, there were no significant differences in VTE. Conclusions Systematic review supports TXA benefits are most evident when given shortly after injury and meta-analysis supports TXA reduces mortality as a single loading dose. Systematic review supports perioperative use of TXA when large volume blood loss is anticipated. Meta-results showed no significant difference in risk of thromboembolism in single-dose TXA treatment compared with placebo. These findings suggest that TXA is safe and effective for control of traumatic bleeding.

The impact of prehospital tranexamic acid on mortality and transfusion requirements: match-pair analysis from the nationwide German TraumaRegister DGU®. CRITICAL CARE : THE OFFICIAL JOURNAL OF THE CRITICAL CARE FORUM 2021; 25:277. [PMID: 34348782 PMCID: PMC8336395 DOI: 10.1186/s13054-021-03701-7] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/25/2021] [Accepted: 07/20/2021] [Indexed: 12/14/2022]
Abstract
Background Outcome data about the use of tranexamic acid (TXA) in civilian patients in mature trauma systems are scarce. The aim of this study was to determine how severely injured patients are affected by the widespread prehospital use of TXA in Germany. Methods The international TraumaRegister DGU® was retrospectively analyzed for severely injured patients with risk of bleeding (2015 until 2019) treated with at least one dose of TXA in the prehospital phase (TXA group). These were matched with patients who had not received prehospital TXA (control group), applying propensity score-based matching. Adult patients (≥ 16) admitted to a trauma center in Germany with an Injury Severity Score (ISS) ≥ 9 points were included. Results The matching yielded two comparable cohorts (n = 2275 in each group), and the mean ISS was 32.4 ± 14.7 in TXA group vs. 32.0 ± 14.5 in control group (p = 0.378). Around a third in both groups received one dose of TXA after hospital admission. TXA patients were significantly more transfused (p = 0.022), but needed significantly less packed red blood cells (p ≤ 0.001) and fresh frozen plasma (p = 0.023), when transfused. Massive transfusion rate was significantly lower in the TXA group (5.5% versus 7.2%, p = 0.015). Mortality was similar except for early mortality after 6 h (p = 0.004) and 12 h (p = 0.045). Among non-survivors hemorrhage as leading cause of death was less in the TXA group (3.0% vs. 4.3%, p = 0.021). Thromboembolic events were not significantly different between both groups (TXA 6.1%, control 4.9%, p = 0.080). Conclusion This is the largest civilian study in which the effect of prehospital TXA use in a mature trauma system has been examined. TXA use in severely injured patients was associated with a significantly lower risk of massive transfusion and lower mortality in the early in-hospital treatment period. Due to repetitive administration, a dose-dependent effect of TXA must be discussed.
