Witzenhausen M, Hossfeld B, Kulla M, Beltzer C. Impact of "hypotension on arrival" on required surgical disciplines and usage of damage control protocols in severely injured patients. Scand J Trauma Resusc Emerg Med 2024; 32:44. [PMID: 38745198 PMCID: PMC11094980 DOI: 10.1186/s13049-024-01187-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2023] [Accepted: 02/16/2024] [Indexed: 05/16/2024] Open
Abstract
BACKGROUND For trauma patients with subsequent immediate surgery, it is unclear which surgical disciplines are most commonly required for treatment, and whether and to what extend this might depend on or change with "hypotension on arrival". It is also not known how frequently damage control protocols are used in daily practice and whether this might also be related to "hypotension on arrival". METHODS A retrospective analysis of trauma patients from a German level 1 trauma centre and subsequent "immediate surgery" between 01/2017 and 09/2022 was performed. Patients with systolic blood pressure > 90 mmHg (group 1, no-shock) and < 90 mmHg (group 2, shock) on arrival were compared with regard to (a) most frequently required surgical disciplines, (b) usage of damage control protocols, and (c) outcome. A descriptive analysis was performed, and Fisher's exact test and the Mann‒Whitney U test were used to calculate differences between groups where appropriate. RESULTS In total, 98 trauma patients with "immediate surgery" were included in our study. Of these, 61 (62%; group 1) were normotensive, and 37 (38%, group 2) were hypotensive on arrival. Hypotension on arrival was associated with a significant increase in the need for abdominal surgery procedures (group 1: 37.1 vs. group 2: 54.5%; p = 0.009), more frequent usage of damage control protocols (group 1: 59.0 vs. group 2: 75.6%; p = 0.019) and higher mortality (group 1: 5.5 vs. group 2: 24.3%; p 0.027). CONCLUSION Our data from a German level 1 trauma centre proof that abdominal surgeons are most frequently required for the treatment of trauma patients with hypotension on arrival among all surgical disciplines (> thoracic surgery > vascular surgery > neurosurgery). Therefore, surgeons from these specialties must be available without delay to provide optimal trauma care.

Abstract
Trauma-induced coagulopathy (TIC) is a leading contributor to preventable mortality in severely injured patients. Understanding the molecular drivers of TIC is an essential step in identifying novel therapeutics to reduce morbidity and mortality. This study investigated multiomics and viscoelastic responses to polytrauma using our novel swine model and compared these findings with severely injured patients. Molecular signatures of TIC were significantly associated with perturbed coagulation and inflammation systems as well as extensive hemolysis. These results were consistent with patterns observed in trauma patients who had multisystem injuries. Here, intervention using resuscitative endovascular balloon occlusion of the aorta following polytrauma in our swine model revealed distinct multiomics alterations as a function of placement location. Aortic balloon placement in zone-1 worsened ischemic damage and mitochondrial dysfunction, patterns that continued throughout the monitored time course. While placement in zone-III showed a beneficial effect on TIC, it showed an improvement in effective coagulation. Taken together, this study highlights the translational relevance of our polytrauma swine model for investigating therapeutic interventions to correct TIC in patients.

Abstract
BACKGROUND Activated protein C (APC) is one of the mechanisms contributing to coagulopathy, which is associated with high mortality. The counteraction of the APC pathway could help ameliorate bleeding. However, patients also transform frequently from a hemorrhagic state to a prothrombotic state at a later time. Therefore, a prohemostatic therapeutic intervention should take this thrombotic risk into consideration. OBJECTIVES CT-001 is a novel factor VIIa (FVIIa) with enhanced activity and desialylated N-glycans for rapid clearance. We assessed CT-001 clearance in multiple species and its ability to reverse APC-mediated coagulopathic blood loss. METHODS The N-glycans on CT-001 were characterized by liquid chromatography-mass spectrometry. Three species were used to evaluate the pharmacokinetics of the molecule. The potency and efficacy of CT-001 under APC pathway-induced coagulopathic conditions were assessed by coagulation assays and bleeding models. RESULTS The N-glycosylation sites of CT-001 had high occupancy of desialylated N-glycans. CT-001 exhibited 5 to 16 times higher plasma clearance in human tissue factor knockin mice, rats, and cynomolgus monkeys than wildtype FVIIa. CT-001 corrected the activated partial thromboplastin time and thrombin generation of coagulopathic plasma to normal in in vitro studies. In an APC-mediated saphenous vein bleeding model, 3 mg/kg of CT-001 reduced bleeding time in comparison with wildtype FVIIa. The correction of bleeding by CT-001 was also observed in a coagulopathic tail amputation severe hemorrhage mouse model. The efficacy of CT-001 is independent of the presence of tranexamic acid, and the combination of CT-001 and tranexamic acid does not lead to increased thrombogenicity. CONCLUSION CT-001 corrected APC pathway-mediated coagulopathic conditions in preclinical studies and could be a potentially safe and effective procoagulant agent for addressing APC-mediated bleeding.

Abstract
INTRODUCTION Tranexamic acid (TXA) is a standard component of Tactical Combat Casualty Care. Recent retrospective studies have shown that TXA use is associated with a higher rate of venous thromboembolic (VTE) events in combat-injured patients. We aim to determine if selective administration should be considered in the prolonged field care environment. MATERIALS AND METHODS We performed a systematic review using the 2020 Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines. Clinical trials and observational studies of combat casualties published between January 1, 1960, and June 20, 2022, were included. We analyzed survival and VTE outcomes in TXA recipients and non-recipients. We discussed the findings of each paper in the context of current and future combat environments. RESULTS Six articles met criteria for inclusion. Only one study was powered to report mortality data, and it demonstrated a 7-fold increase in survival in severely injured TXA recipients. All studies reported an increased risk of VTE in TXA recipients, which exceeded rates in civilian literature. However, five of the six studies used overlapping data from the same registry and were limited by a high rate of missingness in pertinent variables. No VTE-related deaths were identified. CONCLUSIONS There may be an increased risk of VTE in combat casualties that receive TXA; however, this risk must be considered in the context of improved survival and an absence of VTE-associated deaths. To optimize combat casualty care during prolonged field care, it will be essential to ensure the timely administration of VTE chemoprophylaxis as soon as the risk of significant hemorrhage permits.

Abstract
ABSTRACT Introduction : COVID-19-induced coagulopathy (CIC) can increase the risk of thromboembolism without underlying clotting disorders, even when compared with other respiratory viruses. Trauma has a known association with hypercoagulability. Trauma patients with concurrent COVID-19 infection potentially have an even greater risk of thrombotic events. The purpose of this study was to evaluate venous thromboembolism (VTE) rates in trauma patients with COVID-19. Methods : This study reviewed all adult patients (≥18 years of age) admitted to the Trauma Service from April through November 2020 for a minimum of 48 hours. Patients were grouped based off COVID-19 status and compared for inpatient VTE chemoprophylaxis regimen, thrombotic complications defined as deep vein thrombosis, pulmonary embolism, myocardial infarction, and cerebrovascular accident, intensive care unit (ICU) length of stay, hospital length of stay, and mortality. Results : A total of 2,907 patients were reviewed and grouped into COVID-19-positive (n = 110) and COVID-19-negative (n = 2,797) groups. There was no difference in terms of receiving deep vein thrombosis chemoprophylaxis or type, but a longer time to initiation in the positive group ( P = 0.0012). VTE occurred in 5 (4.55%) positive and 60 (2.15%) negative patients without a significant difference between the groups, as well as no difference in type of VTE observed. Mortality was higher ( P = 0.009) in the positive group (10.91%). Positive patients had longer median ICU LOS ( P = 0.0012) and total LOS ( P < 0.001). Conclusion : There were no increased rates of VTE complications between COVID-19-positive and -negative trauma patients, despite a longer time to initiation of chemoprophylaxis in the COVID-19-positive group. COVID-19-positive patients had increased ICU LOS, total LOS, and mortality, which are likely due to multifactorial causes but primarily related to their underlying COVID-19 infection.

Effects of hemodilution on coagulation function during prolonged hypotensive resuscitation in a porcine model of severe hemorrhagic shock. Trauma Surg Acute Care Open 2023; 8:e001052. [PMID: 37213865 PMCID: PMC10193089 DOI: 10.1136/tsaco-2022-001052] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2022] [Accepted: 04/27/2023] [Indexed: 05/23/2023] Open
Abstract
Background Although hemorrhage remains the leading cause of survivable death in casualties, modern conflicts are becoming more austere limiting available resources to include resuscitation products. With limited resources also comes prolonged evacuation time, leaving suboptimal prehospital field care conditions. When blood products are limited or unavailable, crystalloid becomes the resuscitation fluid of choice. However, there is concern of continuous crystalloid infusion during a prolonged period to achieve hemodynamic stability for a patient. This study evaluates the effect of hemodilution from a 6-hour prehospital hypotensive phase on coagulation in a porcine model of severe hemorrhagic shock. Methods Adult male swine (n=5/group) were randomized into three experimental groups. Non-shock (NS)/normotensive did not undergo injury and were controls. NS/permissive hypotensive (PH) was bled to the PH target of systolic blood pressure (SBP) 85±5 mm Hg for 6 hours of prolonged field care (PFC) with SBP maintained via crystalloid, then recovered. Experimental group underwent controlled hemorrhage to mean arterial pressure 30 mm Hg until decompensation (Decomp/PH), followed by PH resuscitation with crystalloid for 6 hours. Hemorrhaged animals were then resuscitated with whole blood and recovered. Blood samples were collected at certain time points for analysis of complete blood counts, coagulation function, and inflammation. Results Throughout the 6-hour PFC, hematocrit, hemoglobin, and platelets showed significant decreases over time in the Decomp/PH group, indicating hemodilution, compared with the other groups. However, this was corrected with whole blood resuscitation. Despite the appearance of hemodilution, coagulation and perfusion parameters were not severely compromised. Conclusions Although significant hemodilution occurred, there was minimal impact on coagulation and endothelial function. This suggests that it is possible to maintain the SBP target to preserve perfusion of vital organs at a hemodilution threshold in resource-constrained environments. Future studies should address therapeutics that can mitigate potential hemodilutional effects such as lack of fibrinogen or platelets. Level of evidence Not applicable-Basic Animal Research.

Abstract
OBJECTIVE The aim: We study vascular-platelet hemostasis peculiarities in patients with severe trauma. PATIENTS AND METHODS Materials and methods: We included 50 patients, who were divided into control (n=15) and study (n=35) groups. The control group included patients without traumatic injuries, study group - patients with severe trauma. The study group was divided into the I subgroup (patients received 1 g tranexamic acid IV at the prehospital stage), and the II subgroup (1 g tranexamic acid IV after hospital admission). RESULTS Results: The main changes in the I subgroup started on the 3rd day, while in the II subgroup - on the 1st day. Patients of both subgroups on the 1st and 3rd days had a normal number of platelets in venous blood, however, on the 3rd day, there was a decreasing level of discocytes whereas the level of discoechinocytes, spherocytes, spheroechinocytes, and the sum of active forms of platelets were increased in comparison with the control group (p<0.05). CONCLUSION Conclusions: The changes in vascular-platelet hemostasis in patients appeared in the I subgroup on the 3rd day, while in the II subgroup - on the 1st day. For the I subgroup was the decreasing level of discocytes, whereas the level of discoechinocytes, spherocytes, spheroechinocytes, and the sum of active forms of platelets were increased. For the II subgroup on the 1st day, there was an increasing sum of active forms of platelets, on the 3rd day - the level of discocytes was decreased, and levels of discoechinocytes, spherocytes, spheroechinocytes, and the sum of active forms of platelets were increased.

Is ROTEM Diagnostic in Trauma Care Associated with Lower Mortality Rates in Bleeding Patients?—A Retrospective Analysis of 7461 Patients Derived from the TraumaRegister DGU®. J Clin Med 2022; 11:jcm11206150. [PMID: 36294471 PMCID: PMC9605144 DOI: 10.3390/jcm11206150] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2022] [Revised: 10/08/2022] [Accepted: 10/14/2022] [Indexed: 12/02/2022] Open
Abstract
Introduction: Death from uncontrolled trauma haemorrhage and subsequent trauma-induced coagulopathy (TIC) is potentially preventable. Point-of-care devices such as rotational thromboelastometry (ROTEM®) are advocated to detect haemostatic derangements more rapidly than conventional laboratory diagnostics. Regarding reductions in RBC transfusion, the use of ROTEM has been described as being efficient and associated with positive outcomes in several studies. Objective: The effect of ROTEM use was assessed on three different outcome variables: (i) administration of haemostatics, (ii) rate of RBC transfusions and (iii) mortality in severely injured patients. Methods and Material: A retrospective analysis of a large data set of severely injured patients collected into the TraumaRegister DGU® between 2009 and 2016 was conducted. The data of 7461 patients corresponded to the inclusion criteria and were subdivided into ROTEM-using and ROTEM-non-using groups. Both groups were analysed regarding (i) administration of haemostatics, (ii) rate of RBC transfusions and (iii) mortality. Results: A lower mortality rate in ROTEM-using groups was observed (p = 0.043). Furthermore, more patients received haemostatic medication when ROTEM was used. In ROTEM-using groups, there was a statistically relevant higher application of massive transfusion. Conclusions: In this retrospective study, the use of ROTEM was associated with reduced mortality and an increased application of haemostatics and RBC transfusions. Prospective evidence is needed for further evidence-based recommendations.

Abstract
INTRODUCTION Trauma patients who develop indications for therapeutic anticoagulation (TAC) present a challenge due to concern for bleeding. Transfusion requirement has been described as a common complication of TAC after trauma but its clinical relevance is unclear. OBJECTIVE Determine risk factors for and clinical outcomes associated with transfusion requirement on TAC after trauma. METHODS All trauma patients admitted to an academic urban level I trauma center from January 2010 to August 2020 who received TAC were included in this retrospective cohort study. Data included injury characteristics; TAC indication and timing; transfusions; and interventions. Patients who required transfusion after TAC were compared to those who did not. RESULTS Eighty-two patients were included. The most common reasons for TAC were deep vein thrombosis (67.1%) and pulmonary embolism (31.7%). Two (2.4%) patients developed gastrointestinal bleeding. One (1.2%) underwent endoscopic intervention. Two patients (4.9%) had intracranial hemorrhage progression. Blood transfusion after TAC initiation was required in 43.9% of patients. Patients who were transfused started TAC more quickly after traumatic injury (5.5 vs 10.0 days, P = .03), had fewer hospital-free days (54 vs 64 days, P < .01), ICU-free days (8.5 vs 16.5 days, P = .01), and higher mortality (13.9% vs 2.1%, P = .04). CONCLUSION Transfusions are common after starting TAC in trauma patients. Requiring transfusion after starting TAC was associated with shorter time from injury to starting TAC, higher mortality, and fewer ICU and hospital-free days.

Abstract
Purpose It has been shown that abnormalities of coagulation and fibrinolysis system are involved in the pathogenesis of necrotizing enterocolitis (NEC), but not well studied challenge in the context of early detection of disease progression. The present study mainly explores the predictive significance of coagulation parameters at the time of NEC diagnosis in identifying the patients who eventually received surgery and/or NEC-related deaths. Methods The retrospective study of 114 neonates with NEC was conducted with assessments of demographic data, laboratory results at the time of NEC diagnosis, treatment methods and prognosis. According to treatment methods, patients were divided into surgical intervention group and medical treatment group. Predictive factors were put forward and determined by receiver operating characteristic (ROC) curve analysis. An analysis of the surgical intervention and prognosis was performed. Results Of 114 patients, 46 (40.4%) cases received surgical intervention and 14 (12.3%) deaths. prothrombin time (PT), PT international normalized ratio, activated partial thromboplastin time (APTT), fibrinogen and platelet count at the time of NEC diagnosis were independently associated with surgical NEC. The APTT could identify patients at high risk for surgical NEC, with 67.39% sensitivity, 86.76% specificity, better than that of other serological parameters. Coagulopathy was found in 38.6% of all patients. For surgical intervention, the area under the ROC curve (AUC) of coagulopathy was 0.869 (95% confidence interval [CI]: 0.794 ~ 0.944, P < 0.001), with 82.61% sensitivity and 91.18% specificity, outperformed APTT (95% CI: 0.236 ~ 0.173, P = 0.001). Furthermore, the AUC for coagulopathy to predict mortality was 0.809 (95% CI: 0.725 ~ 0.877, P < 0.001), with 92.86% sensitivity and 69.0% specificity. Conclusion Coagulation parameters at the time of NEC diagnosis were conducive to early prediction of surgical NEC and -related deaths, which should be closely monitored in neonates at high risk of NEC and validated as a clinical decision-making tool.

Abstract
OBJECTIVES To assess the impact of plasma and platelet ratios and deficits in injured children with life-threatening bleeding. DESIGN Secondary analysis of the MAssive Transfusion epidemiology and outcomes In Children study dataset, a prospective observational study of children with life-threatening bleeding events. SETTING Twenty-four childrens hospitals in the United States, Canada, and Italy. PATIENTS Injured children 0-17 years old who received greater than 40 mL/kg total blood products over 6 hours or were transfused under activation of massive transfusion protocol. INTERVENTION/EXPOSURE Weight-adjusted blood product volumes received during the bleeding event were recorded. Plasma:RBC ratio (plasma/RBC weight-adjusted volume in mL/kg) and platelet:RBC ratio (platelet/RBC weight-adjusted volume in mL/kg) were analyzed. Plasma deficit was calculated as RBC mL/kg - plasma mL/kg; platelet deficit was calculated as RBC mL/kg - platelet mL/kg. MEASUREMENTS AND MAIN RESULTS Of 191 patients analyzed, median (interquartile range) age was 10 years (5-15 yr), 61% were male, 61% blunt mechanism, and median (interquartile range) Injury Severity Score was 29 (24-38). After adjusting for Pediatric Risk of Mortality score, cardiac arrest, use of vasoactive medications, and blunt mechanism, a high plasma:RBC ratio (> 1:2) was associated with improved 6-hour survival compared with a low plasma:RBC ratio (odds ratio [95% CI] = 0.12 [0.03-0.52]; p = 0.004). Platelet:RBC ratio was not associated with survival. After adjusting for age, Pediatric Risk of Mortality score, cardiac arrest, and mechanism of injury, 6-hour and 24-hour mortality were increased in children with greater plasma deficits (10% and 20% increased odds of mortality for every 10 mL/kg plasma deficit at 6 hr [p = 0.04] and 24 hr [p = 0.01], respectively); 24-hour mortality was increased in children with greater platelet deficits (10% increased odds of 24-hr mortality for every 10 mL/kg platelet deficit [p = 0.02)]). CONCLUSIONS In injured children, balanced resuscitation may improve early survival according to this hypothesis generating study. Multicenter clinical trials are needed to assess whether clinicians should target ratios and deficits as optimal pediatric hemostatic resuscitation practice.

Abstract
Despite the manifold recent efforts to improve patient outcomes, trauma still is a clinical and socioeconomical issue of major relevance especially in younger people. The systemic immune reaction after severe injury is characterized by a strong pro- and anti-inflammatory response. Besides its functions as energy storage depot and organ-protective cushion, adipose tissue regulates vital processes via its secretion products. However, there is little awareness of the important role of adipose tissue in regulating the posttraumatic inflammatory response. In this review, we delineate the local and systemic role of adipose tissue in trauma and outline different aspects of adipose tissue as an immunologically active modifier of inflammation and as an immune target of injured remote organs after severe trauma.

Front Med (Lausanne) 2022; 9:783234. [PMID: 35242774 PMCID: PMC8885730 DOI: 10.3389/fmed.2022.783234] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2021] [Accepted: 01/12/2022] [Indexed: 12/12/2022] Open
Abstract
BACKGROUND The incidence of coagulopathy, which was responsible for poor outcomes, was commonly seen among patients with sepsis. In the current study, we aim to determine whether the presence of sepsis-associated coagulopathy (SAC) predicts the clinical outcomes among critically ill patients with postoperative sepsis. METHODS We conducted a single-center retrospective cohort study by including patients with sepsis admitted to surgical ICU of Chinese PLA General Hospital from January 1, 2014 to December 31, 2018. Baseline characteristics and clinical outcomes were compared with respect to the presence of SAC. Kaplan-Meier analysis was applied to calculate survival rate, and Log-rank test was carried out to compare the differences between two groups. Furthermore, multivariable Cox and logistic and linear regression analysis were performed to assess the relationship between SAC and clinical outcomes, including hospital mortality, development of septic shock, and length of hospital stay (LOS), respectively. Additionally, both sensitivity and subgroup analyses were performed to further testify the robustness of our findings. RESULTS A total of 175 patients were included in the current study. Among all included patients, 41.1% (72/175) ICU patients were identified as having SAC. In-hospital mortality rates were significantly higher in the SAC group when compared to that of the No SAC group (37.5% vs. 11.7%; p < 0.001). By performing univariable and multivariable regression analyses, presence of SAC was demonstrated to significantly correlate with an increased in-hospital mortality for patients with sepsis in surgical ICU [Hazard ratio (HR), 3.75; 95% Confidence interval (CI), 1.90-7.40; p < 0.001]. Meanwhile, a complication of SAC was found to be the independent predictor of the development of septic shock [Odds ratio (OR), 4.11; 95% CI, 1.81-9.32; p = 0.001], whereas it was not significantly associated with prolonged hospital LOS (OR, 0.97; 95% CI, 0.83-1.14; p = 0.743). CONCLUSION The presence of SAC was significantly associated with increased risk of in-hospital death and septic shock among postoperative patients with sepsis admitted to ICU. Moreover, there was no statistical difference of hospital LOS between the SAC and no SAC groups.

Development and Internal Validation of a Nomogram to Predict Mortality During the ICU Stay of Thoracic Fracture Patients Without Neurological Compromise: An Analysis of the MIMIC-III Clinical Database. Front Public Health 2022; 9:818439. [PMID: 35004604 PMCID: PMC8727460 DOI: 10.3389/fpubh.2021.818439] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2021] [Accepted: 12/03/2021] [Indexed: 11/13/2022] Open
Abstract
Background: This study aimed to develop and validate a nomogram for predicting mortality in patients with thoracic fractures without neurological compromise and hospitalized in the intensive care unit. Methods: A total of 298 patients from the Medical Information Mart for Intensive Care III (MIMIC-III) database were included in the study, and 35 clinical indicators were collected within 24 h of patient admission. Risk factors were identified using the least absolute shrinkage and selection operator (LASSO) regression. A multivariate logistic regression model was established, and a nomogram was constructed. Internal validation was performed by the 1,000 bootstrap samples; a receiver operating curve (ROC) was plotted, and the area under the curve (AUC), sensitivity, and specificity were calculated. In addition, the calibration of our model was evaluated by the calibration curve and Hosmer-Lemeshow goodness-of-fit test (HL test). A decision curve analysis (DCA) was performed, and the nomogram was compared with scoring systems commonly used during clinical practice to assess the net clinical benefit. Results: Indicators included in the nomogram were age, OASIS score, SAPS II score, respiratory rate, partial thromboplastin time (PTT), cardiac arrhythmias, and fluid-electrolyte disorders. The results showed that our model yielded satisfied diagnostic performance with an AUC value of 0.902 and 0.883 using the training set and on internal validation. The calibration curve and the Hosmer-Lemeshow goodness-of-fit (HL). The HL tests exhibited satisfactory concordance between predicted and actual outcomes (P = 0.648). The DCA showed a superior net clinical benefit of our model over previously reported scoring systems. Conclusion: In summary, we explored the incidence of mortality during the ICU stay of thoracic fracture patients without neurological compromise and developed a prediction model that facilitates clinical decision making. However, external validation will be needed in the future.

Abstract
BACKGROUND The massive transfusion protocol (MTP) is designed to quickly provide blood products at a fixed ratio for the exsanguinating patient. At our academic medical center, the frequency of MTP activation increased over 10-fold between 2008 and 2015, putting inordinate stress on our transfusion service. STUDY DESIGN AND METHODS Gathering a large number of relevant stakeholders, we performed a multidisciplinary root cause analysis (RCA) in response to the acute clinical need to reform our MTP. RESULTS Through the RCA, we identified four principal opportunities for improvement (OFI) associated with our MTP: education, stewardship, process improvement, and communication. Through the deployment of new approaches to each of these OFI, we reduced MTP activations, blood product waste, and transfusion service technologist stress. CONCLUSION The MTP is amenable to improvement, and, although time intensive, the RCA process yields significant favorable effects: improving communication with colleagues, reducing stress within the transfusion service, and improving resource utilization. Activation of the MTP at our institution is now more aligned with its primary purpose: rapidly providing large quantities of blood products to exsanguinating patients.

Am J Emerg Med 2021; 46:404-409. [PMID: 33143960 DOI: 10.1016/j.ajem.2020.10.027] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2020] [Revised: 10/06/2020] [Accepted: 10/15/2020] [Indexed: 11/18/2022] Open
Abstract
BACKGROUND AND PURPOSE Previous studies have identified that the reverse shock index multiplied by the Glasgow Coma Scale score (rSIG) is a good predictor of mortality in trauma patients. However, it is unknown if rSIG has utility as a predictor for massive transfusion (MT) in trauma patients. The present study evaluated the ability of rSIG to predict MT in trauma patients. METHODS This was a retrospective, observational study performed at a level 1 trauma center. Consecutive patients who presented to the trauma center emergency department between January 2016 and December 2018 were included. The predictive ability of rSIG for MT was assessed as our primary outcome measure. Our secondary outcome measures were the predictive ability of rSIG for coagulopathy, in-hospital mortality, and 24-h mortality. We compared the prognostic performance of rSIG with the shock index, age shock index, and quick Sequential Organ Failure Assessment. RESULTS In total, 1627 patients were included and 117 (7.2%) patients received MT. rSIG showed the highest area under the receiver operating characteristic (AUROC) curve (0.842; 95% confidence interval [CI], 0.806--0.878) for predicting MT. rSIG also showed the highest AUROC for predicting coagulopathy (0.769; 95% CI, 0.728-0.809), in-hospital mortality (AUROC 0.812; 95% CI, 0.772-0.852), and 24-h mortality (AUROC 0.826; 95% CI, 0.789-0.864). The sensitivity of rSIG for MT was 0.79, and the specificity of rSIG for MT was 0.77. All tools had a high negative predictive value and low positive predictive value. CONCLUSION rSIG is a useful, rapid, and accurate predictor for MT, coagulopathy, in-hospital mortality, and 24- h mortality in trauma patients.

Abstract
BACKGROUND Although early coagulopathy increases mortality in adults with traumatic brain injury (TBI), less is known about pediatric TBI. OBJECTIVE To describe the prothrombin time (PT), activated partial thromboplastin time (APTT), and platelet levels of children with moderate to severe TBI to identify predictors of early coagulopathy and study the association with clinical outcomes. METHODS Using the Pediatric Acute and Critical Care Medicine Asian Network (PACCMAN) TBI retrospective cohort, we identified patients <16 yr old with a Glasgow Coma Scale (GCS) ≤13. We compared PT, APTT, platelets, and outcomes between children with isolated TBI and multiple trauma with TBI. We performed logistic regressions to identify predictors of early coagulopathy and study the association with mortality and poor functional outcomes. RESULTS Among 370 children analyzed, 53/370 (14.3%) died and 127/370 (34.3%) had poor functional outcomes. PT was commonly deranged in both isolated TBI (53/173, 30.6%) and multiple trauma (101/197, 51.3%). Predictors for early coagulopathy were young age (adjusted odds ratio [aOR] 0.94, 95% CI 0.88-0.99, P = .023), GCS < 8 (aOR 1.96, 95% CI 1.26-3.06, P = .003), and presence of multiple trauma (aOR 2.21, 95% confidence interval [CI] 1.37-3.60, P = .001). After adjusting for age, gender, GCS, multiple traumas, and presence of intracranial bleed, children with early coagulopathy were more likely to die (aOR 7.56, 95% CI 3.04-23.06, P < .001) and have poor functional outcomes (aOR 2.16, 95% CI 1.26-3.76, P = .006). CONCLUSION Early coagulopathy is common and independently associated with death and poor functional outcomes among children with TBI.

Abstract
BACKGROUND The effect of alcohol on the outcome and fibrinolysis phenotype in trauma patients remains unclear. Hence, we performed this study to determine whether alcohol is a risk factor for mortality and fibrinolysis shutdown in trauma patients. MATERIALS AND METHODS A total of 686 patients who presented to our trauma center and underwent rotational thromboelastometry were included in the study. The primary outcome was in-hospital mortality. Logistic regression analysis was performed to determine whether alcohol was an independent risk factor for in-hospital mortality and fibrinolysis shutdown. RESULTS The rate of in-hospital mortality was 13.8% and blood alcohol was detected in 27.7% of the patients among our study population. The patients in the alcohol-positive group had higher mortality rate, higher clotting time, and lower maximum lysis, more fibrinolysis shutdown, and hyperfibrinolysis than those in the alcohol-negative group. In logistic regression analysis, blood alcohol was independently associated with in-hospital mortality (odds ratio [OR] 2.578; 95% confidence interval [CI], 1.550-4.288) and fibrinolysis shutdown (OR 1.883 [95% CI, 1.286-2.758]). Within the fibrinolysis shutdown group, blood alcohol was an independent predictor of mortality (OR 2.168 [95% CI, 1.030-4.562]). CONCLUSIONS Alcohol is an independent risk factor for mortality and fibrinolysis shutdown in trauma patients. Further, alcohol is an independent risk factor for mortality among patients who experienced fibrinolysis shutdown.

Jiang RM, Pourzanjani AA, Cohen MJ, Petzold L. Associations of longitudinal D-Dimer and Factor II on early trauma survival risk. BMC Bioinformatics 2021; 22:122. [PMID: 33714270 PMCID: PMC7955634 DOI: 10.1186/s12859-021-04065-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2020] [Accepted: 03/03/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Trauma-induced coagulopathy (TIC) is a disorder that occurs in one-third of severely injured trauma patients, manifesting as increased bleeding and a 4X risk of mortality. Understanding the mechanisms driving TIC, clinical risk factors are essential to mitigating this coagulopathic bleeding and is therefore essential for saving lives. In this retrospective, single hospital study of 891 trauma patients, we investigate and quantify how two prominently described phenotypes of TIC, consumptive coagulopathy and hyperfibrinolysis, affect survival odds in the first 25 h, when deaths from TIC are most prevalent. METHODS We employ a joint survival model to estimate the longitudinal trajectories of the protein Factor II (% activity) and the log of the protein fragment D-Dimer ([Formula: see text]g/ml), representative biomarkers of consumptive coagulopathy and hyperfibrinolysis respectively, and tie them together with patient outcomes. Joint models have recently gained popularity in medical studies due to the necessity to simultaneously track continuously measured biomarkers as a disease evolves, as well as to associate them with patient outcomes. In this work, we estimate and analyze our joint model using Bayesian methods to obtain uncertainties and distributions over associations and trajectories. RESULTS We find that a unit increase in log D-Dimer increases the risk of mortality by 2.22 [1.57, 3.28] fold while a unit increase in Factor II only marginally decreases the risk of mortality by 0.94 [0.91,0.96] fold. This suggests that, while managing consumptive coagulopathy and hyperfibrinolysis both seem to affect survival odds, the effect of hyperfibrinolysis is much greater and more sensitive. Furthermore, we find that the longitudinal trajectories, controlling for many fixed covariates, trend differently for different patients. Thus, a more personalized approach is necessary when considering treatment and risk prediction under these phenotypes. CONCLUSION This study reinforces the finding that hyperfibrinolysis is linked with poor patient outcomes regardless of factor consumption levels. Furthermore, it quantifies the degree to which measured D-Dimer levels correlate with increased risk. The single hospital, retrospective nature can be understood to specify the results to this particular hospital's patients and protocol in treating trauma patients. Expanding to a multi-hospital setting would result in better estimates about the underlying nature of consumptive coagulopathy and hyperfibrinolysis with survival, regardless of protocol. Individual trajectories obtained with these estimates can be used to provide personalized dynamic risk prediction when making decisions regarding management of blood factors.

Abstract
INTRODUCTION Plasma thrombin generation kinetics as measured by the calibrated automated thrombogram (CAT) assay is a predictor of symptomatic venous thromboembolism after trauma. We hypothesized that data from a new prototype assay for measurement of thrombin generation kinetics in fresh whole blood (near patient testing of thrombin generation), will correlate with the standard CAT assay in the same patients, making it a potential tool in the future care of trauma patients. METHODS Patients were enrolled from June 2018 to February 2020. Within 12 hours of injury, blood samples were collected simultaneously for both assays. Variables compared and correlated between assays were lag time, peak height, time to peak, and endogenous thrombin potential. Data are presented as median with interquartile range (IQR). Spearman and Pearson correlations were estimated and tested between both assays; a P value of <0.05 was considered to be significant. RESULTS A total of 64 trauma patients had samples analyzed: injury severity score = 17 (IQR), 10-26], hospital length of stay = 7.5 (IQR), 2-18) days, age = 52 (IQR, 35-63) years, 71.9% male, and 42.2% of patients received a transfusion within 24 hours of injury. Thrombin generation parameters between plasma and whole blood were compared and found that all parameters of the two assays correlate in trauma patients. CONCLUSION In this pilot study, we have found that a novel point-of-care whole blood thrombin generation assay yields results with modest but statistically significant correlations to those of a standard plasma thrombin generation assay. This finding supports studying this device in a larger, adequately powered study.

Abstract
BACKGROUND Despite the prevalence of hypocoagulability after injury, the majority of trauma patients paradoxically present with elevated thrombin generation (TG). Although several studies have examined plasma TG post injury, this has not been assessed in whole blood. We hypothesize that whole blood TG is lower in hypocoagulopathy, and TG effectively predicts massive transfusion (MT). STUDY DESIGN Blood was collected from trauma activation patients at an urban Level I trauma center. Whole blood TG was performed with a prototype point-of-care device. Whole blood TG values in healthy volunteers were compared with trauma patients, and TG values were examined in trauma patients with shock and MT requirement. RESULTS Overall, 118 patients were included. Compared with healthy volunteers, trauma patients overall presented with more robust TG; however, those arriving in shock (n = 23) had a depressed TG, with significantly lower peak thrombin (88.3 vs 133.0 nM; p = 0.01) and slower maximum rate of TG (27.4 vs 48.3 nM/min; p = 0.04). Patients who required MT (n = 26) had significantly decreased TG, with a longer lag time (median 4.8 vs 3.9 minutes, p = 0.04), decreased peak thrombin (median 71.4 vs 124.2 nM; p = 0.0003), and lower maximum rate of TG (median 15.8 vs 39.4 nM/min; p = 0.01). Area under the receiver operating characteristics (AUROC) analysis revealed lag time (AUROC 0.6), peak thrombin (AUROC 0.7), and maximum rate of TG (AUROC 0.7) predict early MT. CONCLUSIONS These data challenge the prevailing bias that all trauma patients present with elevated TG and highlight that deficient thrombin contributes to the hypocoagulopathic phenotype of trauma-induced coagulopathy. In addition, whole blood TG predicts MT, suggesting point-of-care whole blood TG can be a useful tool for diagnostic and therapeutic strategies in trauma.

Abstract
Penetrating brain injury (PBI) is the most devastating type of traumatic brain injury. Development of coagulopathy in the acute setting of PBI, though common, remains of unclear significance as does its reversal. The aim of this study is to investigate the relationship between coagulopathy and clinical presentation, radiographical features, and outcome in civilian patients with PBI. Eighty-nine adult patients with PBI at a Level I trauma center in Chicago, Illinois who survived acute resuscitation and with available coagulation profile were analyzed. Coagulopathy was defined as international normalized ratio [INR] >1.3, platelet count <100,000 /μL, or partial thromboplastin time >37 sec. Median age (interquartile range; IQR) of our cohort was 27 (21-35) years, and 74 (83%) were male. The intent was assault in 74 cases (83%). The mechanism of PBI was gunshot wound in all patients. Forty patients (45%) were coagulopathic at presentation. In a multiple regression model, coagulopathy was associated with lower Glasgow Coma Scale (GCS)-Motor score (odds ratio [OR], 0.67; confidence interval [CI], 0.48-0.94; p = 0.02) and transfusion of blood products (OR, 3.91; CI, 1.2-12.5; p = 0.02). Effacement of basal cisterns was the only significant radiographical features associated with coagulopathy (OR, 3.34; CI, 1.08-10.37; p = 0.04). Mortality was found to be significantly more common in coagulopathic patients (73% vs. 25%; p < 0.001). However, in our limited sample, reversal of coagulopathy at 24 h was not associated with a statistically significant improvement in outcome. The triad of coagulopathy, low post-resuscitation GCS, and radiographical effacement of basal cisterns identify a particularly ominous phenotype of PBI. The role, and potential reversal of, coagulopathy in this group warrants further investigation.

Abstract
Essentials Striated muscle myosins can promote prothrombin activation by FXa or FVa inactivation by APC. Cardiac myosin and skeletal muscle myosin are pro-hemostatic in murine tail cut bleeding models. Infused cardiac myosin exacerbates myocardial injury caused by myocardial ischemia reperfusion. Skeletal muscle myosin isoforms that circulate in human plasma can be grouped into 3 phenotypes. ABSTRACT: Two striated muscle myosins, namely skeletal muscle myosin (SkM) and cardiac myosin (CM), may potentially contribute to physiologic mechanisms for regulation of thrombosis and hemostasis. Thrombin is generated from activation of prothrombin by the prothrombinase (IIase) complex comprising factor Xa, factor Va, and Ca++ ions located on surfaces where these factors are assembled. We discovered that SkM and CM, which are abundant motor proteins in skeletal and cardiac muscles, can provide a surface for thrombin generation by the prothrombinase complex without any apparent requirement for phosphatidylserine or lipids. These myosins can also provide a surface that supports the inactivation of factor Va by activated protein C/protein S, resulting in negative feedback downregulation of thrombin generation. Although the physiologic significance of these reactions remains to be established for humans, substantive insights may be gleaned from murine studies. In mice, exogenously infused SkM and CM can promote hemostasis as they are capable of reducing tail cut bleeding. In a murine myocardial ischemia-reperfusion injury model, exogenously infused CM exacerbates myocardial infarction damage. Studies of human plasmas show that SkM antigen isoforms of different MWs circulate in human plasma, and they can be used to identify three plasma SkM phenotypes. A pilot clinical study showed that one SkM isoform pattern appeared to be linked to isolated pulmonary embolism. These discoveries enable multiple preclinical and clinical studies of SkM and CM, which should provide novel mechanistic insights with potential translational relevance for the roles of CM and SkM in the pathobiology of hemostasis and thrombosis.

Abstract
Background Severe injury initiates a complex physiologic response encompassing multiple systems and varies phenotypically between patients. Trauma-induced coagulopathy may be an early warning of a poorly coordinated response at the molecular level, including a deleterious immunologic response and worsening of shock states. The onset of trauma-induced coagulopathy (TIC) may be subtle however. In previous work, we identified an early warning sign of coagulopathy from the admission thromboelastogram, called the MAR ratio. We hypothesized that a low MAR ratio would be associated with specific derangements in the inflammatory response. Methods In this prospective, observational study, 88 blunt trauma patients admitted to the intensive care unit (ICU) were identified. Concentrations of inflammatory mediators were recorded serially over the course of a week and the MAR ratio was calculated from the admission thromboelastogram. Correlation analysis was used to assess the relationship between MAR and inflammatory mediators. Dynamic network analysis was used to assess coordination of immunologic response. Results Seventy-nine percent of patients were male and mean age was 37 years (SD 12). The mean ISS was 30.2 (SD 12) and mortality was 7.2%. CRITICAL patients (MAR ratio ≤14.2) had statistically higher shock volumes at three time points in the first day compared to NORMAL patients (MAR ratio >14.2). CRITICAL patients had significant differences in IL-6 (P=0.0065), IL-8 (P=0.0115), IL-10 (P=0.0316) and MCP-1 (P=0.0039) concentrations compared to NORMAL. Differences in degree of expression and discoordination of immune response continued in CRITICAL patients throughout the first day. Conclusions The admission MAR ratio may be the earliest warning signal of a pathologic inflammatory response associated with hypoperfusion and TIC. A low MAR ratio is an early indication of complicated dysfunction of multiple molecular processes following trauma.

Abstract
Introduction: Recognising acute traumatic coagulopathy (ATC) poses a significant challenge to improving survival in emergency care. Paramedics are in a prime position to identify ATC in pre-hospital major trauma and initiate appropriate coagulopathy management. Method: A database literature review was conducted using Scopus, CINAHL and MEDLINE. Results: Two themes were identified from four studies: prediction tools, and point-of-care testing. Prediction tools identified key common ATC markers in the pre-hospital setting, including: systolic blood pressure, reduced Glasgow Coma Score and trauma to the chest, abdomen and pelvis. Point-of-care testing was found to have limited value. Conclusion: Future research needs to explore paramedics using prediction tools in identifying ATC, which could alert hospitals to prepare for blood products for damage control resuscitation.

Abstract
Aim We performed a retrospective investigation to determine the factors, including vital signs, severity of traumatic anatomical abnormality and biochemical data, which are most useful for predicting the outcomes of trauma patients after admission. Methods A retrospective medical chart review was performed for all trauma patients who were admitted to our department from September 2017 to August 2019. These subjects were then divided into two groups according to whether they survived to hospital discharge or not. Results During the investigation period, 790 patients were enrolled as subjects (Death group, n = 34; survival group, n = 756). The injury severity score, serum glucose level, prothrombin time, international normalized ratio and fibrin/fibrinogen degradation product level in the Death group were significantly greater than those in the Survival group. A multivariate analysis showed that the fibrin/fibrinogen degradation product level was a significant predictor of a fatal outcome (odds ratio 1.00, 95% confidence interval 1.0008-1.0040, p value = 0.0008). Conclusions The fibrin/fibrinogen degradation product levels on arrival may be a better predictor of a fatal outcome in trauma patients than physiological or anatomical severity.

Early re-laparotomy for patients with high-grade liver injury after damage-control surgery and perihepatic packing. Surg Today 2020; 51:891-896.

Abstract
Purpose The likelihood of re-bleeding after damage-control surgery (DCS) and perihepatic packing for high-grade liver injuries is a major concern. Thus, although early re-laparotomy tends to be recommended, we conducted this study to evaluate the feasibility of performing definite laparotomy within ≤ 48 h in this clinical population. Methods The subjects of this retrospective study were 65 patients (n = 24, ≤ 48-h group; n = 41, > 48-h group) who underwent DCS and perihepatic packing. The primary outcome was the rate of repacking for bleeding during re-laparotomy and the secondary outcomes were mortality and length of stay in the intensive care unit (ICU). Results The ≤ 48-h group had a higher rate of angioembolization and transfusion of red blood cells (RBCs), fresh frozen plasma, and platelets, but the rates of repacking and mortality were not significantly different between the groups. However, the incidence of pneumonia and ventilation support requirement were significantly lower in the ≤ 48-h group than in the > 48-h group. Conclusion The re-laparotomy performed within ≤ 48 h after DCS and perihepatic packing is feasible for patients with high grade liver injury, using angioembolization and aggressive transfusion, as required. Early re-laparotomy reduces the need for prolonged ventilator support and the incidence of ventilator-associated pneumonia.

[PMID: 33153102 PMCID: PMC7692238 DOI: 10.3390/jcm9113544] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2020] [Revised: 10/28/2020] [Accepted: 10/30/2020] [Indexed: 11/16/2022] Open
Abstract
Geriatric trauma is expected to increase due to the lifestyle and activity of the aging population and will be among the major future challenges in health care. Therefore, the aim of this study was to investigate differences between polytraumatized geriatric and non-geriatric patients regarding mortality, length-of-stay and complications with a matched pair analysis. We included patients older than 17 years with an Injury Severity Score (ISS) of 16 or more admitted to our level 1 trauma center between January 2008 and December 2015. The cohort was stratified into two groups (age < 70 and ≥ 70 years). One-to-one matching was performed based on gender, ISS, mechanism of injury (penetrating/blunt), Glasgow coma scale (GCS), base excess, and the presence of coagulopathy (international normalized ratio (INR) ≥ 1.4). Outcome was compared using the paired t-test and McNemar-test. A total of 1457 patients were identified. There were 1022 male (70%) and 435 female patients. Three hundred and sixty-four patients (24%) were older than 70 years. Matching resulted in 57 pairs. Mortality as well as length-of-stay were comparable between geriatric and non-geriatric polytraumatized patients. Complication rate (34% vs. 56%, p = 0.031) was significantly higher in geriatric patients. This indicates the possibility of similar outcomes in geriatric polytraumatized patients receiving optimal care.

Fibrin monomers and association with significant hemorrhage or mortality in severely injured trauma patients. Injury 2020; 51:2483-2492. [PMID: 32741604 DOI: 10.1016/j.injury.2020.07.057] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/16/2020] [Revised: 07/04/2020] [Accepted: 07/26/2020] [Indexed: 02/02/2023]
Abstract
BACKGROUND Post-traumatic hemorrhage is still the leading cause of potentially preventable death in patients with severe trauma. Traumatic-induced coagulopathy has been described as a risk factor for significant hemorrhage and mortality in this population. Fibrin monomers (FMs) are a direct marker of thrombin action, and thus reflect coagulation activation. This study sought to determine the association of FMs levels at admission with significant hemorrhage and 28-day mortality after a severe trauma. METHODS We conducted a retrospective, observational study including all severe trauma patients admitted in a level-1 trauma center between January 2012 and December 2017. Patients with severe traumatic brain injury or previous anticoagulant / antiaggregant therapies were excluded. FMs measurements and standard coagulation test were taken at admission. Significant hemorrhage was defined as a hemorrhage requiring the transfusion of ≥ 4 Red Blood Cells units during the first 6 h. Multivariable analysis was applied to identify predictors of significant hemorrhage and a simple logistic regression analysis was applied to identify an association between FMs and 28-day mortality. RESULTS Overall, 299 patients were included. A total of 47 (16%) experienced a significant hemorrhage. The ROC curve demonstrated that FMs had a poor accuracy to predict the occurrence of significant hemorrhage with an AUC of 0.65 (0.57-0.74). The best threshold at 92.45 µg/ml had excellent sensitivity (87%) and negative predictive value (95%), but was not independently associated with significant hemorrhage (OR = 1.5; 95%CI (0.5-4.2)). The 28-day mortality rate was 5%. In simple logistic regression analysis, FMs values ≥109.5 µg/ml were significantly associated with 28-day mortality (unadjusted OR = 13.2; 95%CI (1.7-102)). CONCLUSIONS FMs levels at admission are not associated with the occurrence of a significant hemorrhage in patients with severe trauma. However, the excellent sensitivity and NPV of FMs could help to identify patients with a low risk of severe bleeding during hospital care. In addition, FMs levels ≥109.5 µg/ml might be predictive of 28-day mortality.

Abstract
BACKGROUND The aim was to examine the risk of post-operative myocardial injury after major emergency abdominal surgery and identify pre- and intra-operative risk factors of post-operative myocardial injury. Moreover, the study aimed to examine the association between post-operative myocardial injury and clinical outcomes. METHODS This was a retrospective cohort study including patients undergoing major emergency abdominal surgery from February 2017 to January 2019. Troponin I was assessed on post-operative days 1-3. Post-operative myocardial injury was defined as a cardiac troponin I ≥ 45 ng per litre. Post-operative clinical outcomes included in-hospital myocardial infarction, in-hospital major adverse cardiovascular events, reoperation, admission to the intensive care unit, lengths of stay, 30- and 90-day all-cause mortality. RESULTS 98 out of 401 patients (24.4%) sustained a post-operative myocardial injury within the third post-operative day. Increasing age was an independent risk factor of post-operative myocardial injury (age per 10 years adjusted odds ratio 2.2 [95% CI 1.7-2.9], P < .0001). Patients with post-operative myocardial injury had an increased risk of major adverse cardiovascular events, a higher admission rate to the intensive care unit, a longer median post-operative length of stay and a higher 30- and 90-day all-cause mortality compared with patients without myocardial injury. CONCLUSION One in four patients suffered a post-operative myocardial injury within the third post-operative day. Post-operative myocardial injury was a risk factor of adverse cardiac and non-cardiac clinical outcomes. Troponin monitoring could potentially improve the post-operative risk stratification in this cohort of high-risk surgical patients.

Abstract
Background Accidental hypothermia is a known predictor for worse outcomes in trauma patients, but has not been comprehensively assessed in a meta-analysis so far. The aim of this systematic review and meta-analysis was to investigate the impact of accidental hypothermia on mortality in trauma patients overall and patients with traumatic brain injury (TBI) specifically. Methods This is a systematic review and meta-analysis using the Ovid Medline/PubMed database. Scientific articles reporting accidental hypothermia and its impact on outcomes in trauma patients were included in qualitative synthesis. Studies that compared the effect of hypothermia vs. normothermia at hospital admission on in-hospital mortality were included in two meta-analyses on (1) trauma patients overall and (2) patients with TBI specifically. Meta-analysis was performed using a Mantel–Haenszel random-effects model. Results Literature search revealed 264 articles. Of these, 14 studies published 1987–2018 were included in the qualitative synthesis. Seven studies qualified for meta-analysis on trauma patients overall and three studies for meta-analysis on patients with TBI specifically. Accidental hypothermia at admission was associated with significantly higher mortality both in trauma patients overall (OR 5.18 [95% CI 2.61–10.28]) and patients with TBI specifically (OR 2.38 [95% CI 1.53–3.69]). Conclusions In the current meta-analysis, accidental hypothermia was strongly associated with higher in-hospital mortality both in trauma patients overall and patients with TBI specifically. These findings underscore the importance of measures to avoid accidental hypothermia in the prehospital care of trauma patients.

Abstract
BACKGROUND Hemorrhage is the most common preventable cause of death in both civilian and military trauma. There is no consensus regarding the appropriate fluid resuscitation protocol. Plasma, as a resuscitative fluid, has substantial benefits as a volume expander, owing to its relatively high oncotic pressure and its positive effect on trauma-induced coagulopathy by replenishing the lost coagulation factors, rather than diluting the casualty's remaining factors. The Israel Defense Force Medical Corps decided to use freeze-dried plasma (FDP) as the fluid of choice for casualties in hemorrhagic shock in the prehospital setting. The aim of our study is to compare the differences of coagulation, perfusion measurements, resource utilization, and outcome between casualties receiving FDP to casualties who did not receive FDP in the prehospital setting. METHODS This is a retrospective matched cohort study based on two groups of casualties (those treated with FDP vs. those without FDP treatment). The control group was compiled in three steps of precision for age, sex, mechanism of injury and maximum level of severity for each nine injured body regions. Data were collected from the IDF Trauma Registry and The National Israel Trauma Registry. RESULTS The study group comprised 48 casualties receiving FDP and 48 controls with no differences in demographic, evacuation time, and injury characteristics. The FDP group demonstrated a lower level of hemoglobin (12.7 gr/dzl) (odds ratio [OR], 3.11; 95% confidence interval [CI], 1.10-8.80), lower level of international normalized ratio (1.1) (OR, 3.09; 95% CI, 1.04-9.14), and lower level of platelets (230 × 109/L) (OR, 3.06; 95% CI, 1.16-8.06). No other differences were found between the two groups. CONCLUSION The use of FDP in the prehospital setting has logistic benefits and a positive effect on coagulation profile, with no other significant effects. Future studies need to be performed on larger groups to verify trends or nullify our hypotheses. LEVEL OF EVIDENCE Therapeutic, level IV.

Mortality and Complication Rates in Adult Trauma Patients Receiving Tranexamic Acid: A Single-center Experience in the Post-CRASH-2 Era. Acad Emerg Med 2020; 27:358-365. [PMID: 32189440 DOI: 10.1111/acem.13883] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2019] [Revised: 10/01/2019] [Accepted: 10/03/2019] [Indexed: 12/11/2022]
Abstract
OBJECTIVES The CRASH-2 trial demonstrated that tranexamic acid (TXA) in adults with significant traumatic hemorrhage safely reduces mortality. Given that the CRASH-2 trial did not include U.S. sites, our objective was to evaluate patient characteristics, TXA dosing strategies, and the incidence of mortality and adverse events in adult trauma patients receiving TXA at a U.S. Level I trauma center in the post-CRASH-2 era. METHODS We conducted a retrospective study that included patients aged 18 years or older who received TXA after an acute injury from July 2014 to June 2017. We excluded patients who received TXA orally, patients who received TXA for elective surgical procedures or nontrauma indications, patients who received it 8 hours or longer after the time of injury, and patients with cardiac arrest at time of emergency department arrival. Trained abstractors collected data from the trauma registry and hospital electronic medical records. Our primary outcome measures were in-hospital death and acute thromboembolic events within 28 days from injury. RESULTS We included 273 patients with a mean (±SD) age of 43.8 (±18.7) years. The mean (±SD) time of administration of TXA from time of injury was 1.55 (±1.2) hours with 229 patients (83.9%) receiving TXA within 3 hours. The overall mortality within 28 days from injury was 12.8% (95% confidence interval [CI] = 8.9% to 16.7%), which was similar compared to that in the CRASH-2 trial (14.5%, 95% CI = 13.9% to 15.2%). The incidence of acute thromboembolic events was 6.6% (95% CI = 3.7% to 9.5%), which was higher than that in the CRASH-2 trial (2.0%, 95% CI = 1.73% to 2.27%). Patients in our cohort also received surgery (64.8% vs. 47.9%) and blood transfusions (74.0% vs. 50.4%) more frequently than those in the CRASH-2 cohort. CONCLUSIONS Adult trauma patients receiving TXA had similar incidences of death but higher incidences of thromboembolic events compared to the CRASH-2 trial. Variation in patient characteristics, injury severity, TXA dosing, and surgery and transfusion rates could explain these observed differences. Further research is necessary to provide additional insight into the incidence and risk factors of thromboembolic events in TXA use.

Abstract
Rotational thromboelastometry (ROTEM) can only detect high-degree hyperfibrinolysis (HF), despite being frequently used in trauma patients. We investigated whether considering FIBTEM HF (the presence of maximal lysis (ML) > 15%) could increase ROTEM-based HF detection’s sensitivity. This observational cohort study was performed at a level 1 trauma centre. Trauma patients with an Injury Severity Score (ISS) > 15 who underwent ROTEM in the emergency department between 2016 and 2017 were included. EXTEM HF was defined as ML > 15% in EXTEM. We compared mortality rates between EXTEM HF, FIBTEM HF, and non-HF patient groups. Overall, 402 patients were included, of whom 45% were men (mean age, 52.5 years; mean ISS, 27). The EXTEM HF (n = 37), FIBTEM HF (n = 132), and non-HF (n = 233) groups had mortality rates of 81.1%, 22.3%, and 10.3%, respectively. The twofold difference in mortality rates between the FIBTEM HF and non-HF groups remained statistically significant after Bonferroni correction (P = 0.01). On multivariable Cox regression analysis, FIBTEM HF was independently associated with in-hospital mortality (adjusted hazard ratio 2.15, 95% confidence interval 1.21–3.84, P = 0.009). Here, trauma patients with FIBTEM HF had significantly higher mortality rates than those without HF. FIBTEM be a valuable diagnostic method to improve HF detection’s sensitivity in trauma patients.

Abstract
Background Pelvic fracture with high energy trauma has a high mortality rate, especially in men. In addition, severe multiple trauma, major hemorrhage, and administration of red blood cells predict mortality in elderly patients with pelvic fracture. We herein report a rare case in which multiple arterial embolization occurred after pelvic fracture. Case presentation An 83-year-old male cyclist was transported to our hospital after being struck by a car. On arrival, he was diagnosed with multiple trauma, including rib fractures with hemothorax, lumbar fractures of the transverse process, and injuries in the right acetabulum, left adrenal gland, and liver. He underwent massive transfusion and transcatheter arterial embolization due to extravasation from the right superior gluteal artery and left adrenal gland. On the second day, owing to right lower leg ischemia, serum creatinine kinase and myoglobin levels were markedly elevated from the reference value; hence, a right above-knee amputation was performed 12 h after the accident. However, both protein levels remained high after amputation, resulting in acute renal injury, which was treated via hemodiafiltration on hospital day 3. In addition, sustained low efficiency hemodialysis and plasma exchange were performed on hospital day 4. Despite these treatments, the patient’s hemodynamics did not improve, and he died on hospital day 8. The autopsy revealed necropsy of the iliopsoas muscles and the digestive tract. Conclusions The causes of the patient’s death were considered to be persistent rhabdomyolysis and severe hypotension due to iliopsoas necrosis and peritonitis due to digestive tract necrosis. Multiple arterial embolization caused by consumption coagulopathy associated with multiple trauma may account for severe outcomes in this case.

Serum Copeptin levels in the emergency department predict major clinical outcomes in adult trauma patients. BMC Emerg Med 2020; 20:14. [PMID: 32093639 PMCID: PMC7041089 DOI: 10.1186/s12873-020-00310-5] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2019] [Accepted: 02/11/2020] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Early prognostication in trauma patients is challenging, but particularly important. We wanted to explore the ability of copeptin, the C-terminal fragment of arginine vasopressin, to identify major trauma, defined as Injury Severity Score (ISS) > 15, in a heterogeneous cohort of trauma patients and to compare its performances with lactate. We also evaluated copeptin performance in predicting other clinical outcomes: mortality, hospital admission, blood transfusion, emergency surgery, and Intensive Care Unit (ICU) admission. METHODS This single center, pragmatic, prospective observational study was conducted at Arcispedale Santa Maria Nuova, a level II trauma center in Reggio Emilia, Italy. Copeptin determination was obtained on Emergency Department (ED) arrival, together with venous lactate. Different outcomes were measured including ISS, Revised Trauma Score (RTS), hospital and ICU admission, blood transfusion, emergency surgery, and mortality. RESULTS One hundred and twenty five adult trauma patients admitted to the ED between June 2017 and March 2018. Copeptin showed a good ability to identify patients with ISS > 15 (AUC 0.819). Similar good performances were recorded also in predicting other outcomes. Copeptin was significantly superior to lactate in identifying patients with ISS > 15 (P 0.0015), and in predicting hospital admission (P 0.0002) and blood transfusion (P 0.016). Comparable results were observed in a subgroup of patients with RTS 7.84. CONCLUSIONS In a heterogeneous group of trauma patients, a single copeptin determination at the time of ED admission proved to be an accurate biomarker, statistically superior to lactate for the identification of major trauma, hospital admission, and blood transfusion, while no statistical difference was observed for ICU admission and emergency surgery. These results, if confirmed, may support a role for copeptin during early management of trauma patients.

Variability in international normalized ratio and activated partial thromboplastin time after injury are not explained by coagulation factor deficits. J Trauma Acute Care Surg 2020; 87:582-589.

Abstract
BACKGROUND Conventional coagulation assays (CCAs), prothrombin time (PT)/international normalized ratio (INR) and activated partial thromboplastin time (aPTT), detect clotting factor (CF) deficiencies in hematologic disorders. However, there is controversy about how these CCAs should be used to diagnose, treat, and monitor trauma-induced coagulopathy. Study objectives were to determine whether CCA abnormalities are reflective of deficiencies of coagulation factor activity in the setting of severe injury. METHODS Patients without previous CF deficiency within a prospective database at an ACS-verified Level I trauma center had CF activity levels, PT/INR, aPTT, and fibrinogen levels measured upon emergency department arrival from 2014 to 2017. Linear regression assessed how CF activity explained the aPTT and PT/INR variation. Prolonged CCA values were set as INR greater than 1.3 and aPTT greater than 34 seconds. CF deficiency was defined as less than 30% activity, except for fibrinogen, defined as less than 150 mg/dL. RESULTS Sixty patients with a mean age of 35.8 (SD, 13.6) years and median New Injury Severity Score of 32 (interquartile range, 12-43) were included; 53.3% sustained blunt injuries, 23.3% required massive transfusion, and mortality was 11.67%. Overall, 44.6% of the PT/INR variance and 49.5% of the aPTT variance remained unexplained by CF activity. Deficiencies of CFs were: common pathway, 25%; extrinsic pathway, 1.7%; and intrinsic pathway, 6.7%. The positive predictive value for CF deficiencies were: (1) PT/INR greater than 1.3:4.4% for extrinsic pathway, 56.5% for the common pathway; (2) aPTT greater than 34 seconds:16.7% for the intrinsic pathway, 73.7% for the common pathway. CONCLUSION Almost half of the variances of PT/INR and aPTT were unexplained by CF activity. Prolonged PT/INR and aPTT were poor predictors of deficiencies in the intrinsic or extrinsic pathways; however, they were indicators of common pathway deficiencies. LEVEL OF EVIDENCE Prognostic, level III.

Abstract
Children with critical illness frequently manifest imbalances in hemostasis with risk of consequent bleeding or pathologic thrombosis. Traditionally, plasma-based tests measuring clot formation by time to fibrin clot generation have been the "gold standard" in hemostasis testing. However, these tests are not sensitive to abnormalities in fibrinolysis or in conditions of enhanced clot formation that may lead to thrombosis. Additionally, they do not measure the critical roles played by platelets and endothelial cells. An added factor in the evaluation of these plasma-based tests is that in infants and young children plasma levels of many procoagulant and anticoagulant proteins are lower than in older children and adults resulting in prolonged clot generation times in spite of maintaining a normal hemostatic "balance." Consequently, newer assays directly measuring thrombin generation in plasma and others assessing the stages hemostasis including clot initiation, propagation, and fibrinolysis in whole blood by viscoelastic methods are now available and may allow for a global measurement of the hemostatic system. In this manuscript, we will review the processes by which clots are formed and by which hemostasis is regulated, and the rationale and limitations for the more commonly utilized tests. We will also discuss selected newer tests available for the assessment of hemostasis, their "pros" and "cons," and how they compare to the traditional tests of coagulation in the assessment and management of critically ill children.

Abstract
Health care professionals must understand the impact of blood product transfusions and transfusion therapy procedures to ensure high-quality patient care, positive outcomes, and wise use of resources in blood management programs. Understanding transfusions of blood and blood products is also important because of the number of treatments performed, which affects individual patients and health care system resources. This article reviews research findings to acquaint health care professionals with the most successful protocols for blood, blood product, and coagulation factor transfusions. Damage control resuscitation in bleeding trauma patients, protocols for patients without trauma who are undergoing surgical procedures that place them at risk for excessive bleeding, and protocols for patients with sepsis are addressed. Emerging research continues to help guide mass transfusion treatments (restrictive vs liberal, balanced, and goal-directed treatment). Although available study results provide some guidance, questions remain. Additional research by health care professionals is needed.

Whole blood thrombin generation is distinct from plasma thrombin generation in healthy volunteers and after severe injury. Surgery 2019; 166:1122-1127. [PMID: 31522748 DOI: 10.1016/j.surg.2019.07.014] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/21/2019] [Revised: 05/16/2019] [Accepted: 07/03/2019] [Indexed: 10/26/2022]
Abstract
BACKGROUND Plasma thrombin generation has been used to characterize trauma-induced coagulopathy, but description of whole blood thrombin generation is lacking. This study aimed to evaluate plasma and whole blood thrombin generation in healthy volunteers and trauma patients. We hypothesized that (1) plasma and whole blood thrombin generation are distinct, (2) whole blood thrombin generation is more pronounced in trauma patients than in healthy volunteers, and (3) thrombin generation correlates with clinical coagulation assays. METHODS Blood was collected from healthy volunteers and trauma patients at a single, level-1 trauma center. Whole blood thrombin generation was assessed with a prototype point-of-care whole blood thrombin generation device, and plasma thrombin generation was measured with a calibrated automated thrombogram analogue. Plasma and whole blood thrombin generation were compared and correlated with international normalized ratio and thrombelastography. RESULTS Overall, 10 healthy volunteers (average age 30, 50% men) were included and 58 trauma patients (average age 34, 76% men, 55% blunt mechanism, and with a median new injury severity score of 17) were included. Plasma and whole blood thrombin generation differed with more robust thrombin generation in plasma. Trauma patients had a significantly increased whole blood thrombin generation compared with healthy volunteers]. Plasma thrombin generation correlated with international normalized ratio, whereas whole blood thrombin generation did not correlate with thrombelastography. CONCLUSION Plasma and whole blood thrombin generation are distinct, highlighting the need to perform standardized assays to better understand their correlation and to assess how whole blood thrombin generation confers differential outcomes in trauma.

Abstract
A critical tool in the successful management of patients with abnormal placentation is an established massive transfusion protocol designed to rapidly deliver blood products in obstetrical and surgical hemorrhage. Spurred by trauma research and an understanding of consumptive coagulopathy, the past 2 decades have seen a shift in volume resuscitation from an empiric, crystalloid-based method to balanced, targeted transfusion therapy. The present article reviews patient blood management in abnormal placentation, beginning with optimizing the patient's status in the antenatal period to the laboratory assessment and transfusion strategy for blood products at the time of hemorrhage.

Abstract
Obstetrical hemorrhage is the most common cause of maternal mortality worldwide. Together with adequate surgical control and judicious transfusion of blood products, the use of pharmacological agents (e.g., tranexamic acid) and clotting factor concentrates (e.g., fibrinogen concentrates and prothrombin complex concentrates) results in improved hemostasis and decreased bleeding-associated mortality. Guidance in the administration of these agents with the use of viscoelastic testing will likely become standard of care in the near future.

Abstract
BACKGROUND Increased life expectancy causes higher prevalence of chronic diseases and greater frailty among older persons. Osteoarthritis and hip fracture are the leading causes of disability among the older persons in high income countries. Recent studies showed that patients undergoing hip fracture surgery have an increased risk of mortality and developing complications. The aim of this study was to compare the occurrence of in-hospital mortality events, complications, and 30-hospital readmissions among patients undergoing hip fracture surgery (HFS) and elective hip replacement (EHR). METHODS The study considered all hospital admissions for HFS and EHR performed from 2006 to 2015 in Abruzzo region, Italy. Data were collected from hospital discharge records. To compare outcomes between HFS and EHR, a propensity score matching procedure was performed. Odds ratios with 95% confidence intervals for primary and secondary outcomes were computed using logistic regression models. RESULTS A total of 32,248 patients were selected: 23,075 underwent HFS and 9173 underwent EHR. After matching, 18,078 patients were included in the analyses (9039 patients who underwent HFS and 9039 patients who underwent HER). In the matched population, HFS patients showed an increased risk of in-hospital mortality (OR 2.03; 95% CI 1.58-2.61) and 30-day hospital readmission (OR 1.97; 95% CI 1.85-2.09). A sensitivity analysis performed on patients younger than 65 years of age confirmed these findings. CONCLUSIONS In a cohort of Italian patients, hip fracture surgery was associated with a higher risk of in-hospital mortality and 30-day readmission when compared to elective hip replacement.

Abstract
BACKGROUND A number of clinical systematic review and meta-analysis have been published on the use of tranexamic in the obstetric setting. The aim of this meta-analysis was to evaluate the safety and effectiveness of tranexamic acid in reducing blood loss when given prior to caesarean delivery. MATERIALS AND METHODS We searched the Cochrane Wounds Specialized Register, Cochrane Central, MEDLINE (through PUBMED), Embase, and SCOPUS electronic databases. We also searched clinical trials registries for ongoing and unpublished studies, and checked reference lists to identify additional studies. We used no restrictions with respect to language and date of publication. Two review authors independently performed study selection, "Risk of bias" assessment, and data extraction. Initial disagreements were resolved by discussion, or by including a third review author when necessary. RESULTS We found 18 randomised controlled trials (RCTs) that met our inclusion criteria. Overall, 1,764 women receiving intravenous tranexamic acid for prevention of bleeding following caesarean sections and 1,793 controls receiving placebo were enrolled in the 18 RCTs evaluated. The use of tranexamic acid compared to controls (placebo or no intervention) reduces post-partum haemorrhage >400 mL (risk ratio [RR] 0.40, 95% confidence interval [CI] 0.24-0.65; 5 trials with a total of 786 participants), severe post-partum haemorrhage >1,000 mL (RR 0.32, 95% CI: 0.12-0.84; 5 trials with a total of 1,850 participants), and need for red blood cell transfusion (RR 0.30, 95% CI: 0.18-0.49; 10 trials with a total of 1,873 participants). No particular safety concerns on the use of this antifibrinolytic agent emerged from the analysis of the 18 RCTs included. DISCUSSION Overall, the results of this meta-analysis support the evidence of a beneficial effect of tranexamic acid in reducing blood loss and need for blood transfusion in pregnant women undergoing caesarean section.

Abstract
Bone marrow, the vital organ which maintains lifelong hemopoiesis, currently receives considerable attention, as a source of multiple cell types which may play important roles in repair at distant sites. This emerging function, distinct from, but closely related to, bone marrow roles in innate immunity and inflammation, has been characterized through a number of strategies. However, the use of surgical models in this endeavour has hitherto been limited. Surgical strategies allow the experimenter to predetermine the site, timing, severity and invasiveness of injury; to add or remove aggravating factors (such as infection and defects in immunity) in controlled ways; and to manipulate the context of repair, including reconstitution with selected immune cell subpopulations. This endows surgical models overall with great potential for exploring bone marrow responses to injury, inflammation and infection, and its roles in repair and regeneration. We review three different murine surgical models, which variously combine trauma with infection, antigenic stimulation, or immune reconstitution, thereby illuminating different aspects of the bone marrow response to systemic injury in sepsis, trauma and allergy. They are: (1) cecal ligation and puncture, a versatile model of polymicrobial sepsis; (2) egg white implant, an intriguing model of eosinophilia induced by a combination of trauma and sensitization to insoluble allergen; and (3) ectopic lung tissue transplantation, which allows us to dissect afferent and efferent mechanisms leading to accumulation of hemopoietic cells in the lungs. These models highlight the gain in analytical power provided by the association of surgical and immunological strategies.
