Abstract
Sudden cardiac arrest remains a relevant problem with a significant number of deaths worldwide. Although survival rates have more than tripled over the last 20 years (4% in 2001 vs. 14% in 2020), survival rates with good neurological outcomes remain persistently low, representing a major socioeconomic problem. Every minute of delay from patient collapse to start cardiopulmonary resuscitation (CPR) and early defibrillation reduces the chance of survival by approximately 10-12%. Therefore, the time to treatment is a crucial factor in the prognosis of patients with out-of-hospital cardiac arrest (OHCA). Research teams working in the pre-hospital setting are therefore looking for ways to improve the transmission of information from the site of an emergency event and to make it easier for emergency medical dispatch centres (EMDC) to recognise life-threatening conditions with minimal deviation. For emergency unit procedures already at the scene of the event, methods are being sought to efficiently and temporarily replace a non-functioning cardiopulmonary system. In the case of traumatic cardiac arrest (TCA), the focus is mainly on effective affecting non-compressible haemorrhage.

Abstract
OBJECTIVES Emergency treatment of patients with severe subphrenic vascular trauma often adopts resuscitative thoracotomy or endovascular balloon. This case report proposes a non-invasive method to treat patients with vascular trauma, mainly through ultrasound-guided positioning of the proximal aorta and applying pressure to occlude the aorta and limit the distal blood flow, using bedside ultrasound to achieve accurate compression, continuous monitoring of its efficacy, and early detection of the recovery of autonomic circulation in patients with cardiac arrest. METHODS We introduced a case of left iliac artery injury caused by a knife wound and subsequent cardiac arrest.Results We tried to externally compress the proximal aorta under bedside US guidance to achieve and maintain the recovery of the autonomic circulation. This allowed the patient to be transferred from the emergency department to the operating room. CONCLUSION This case demonstrated that ultrasound-guided proximal external aortic compression can be used as a bridge for further treatment of patients with vascular trauma, such as resuscitative thoracotomy or endoaortic balloon or covered stent occlusion.

Safety of the injectable expanding biopolymer foam for non-compressible truncal bleeding in swine. Surgery 2024; 175:1189-1197. [PMID: 38092635 DOI: 10.1016/j.surg.2023.11.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2023] [Revised: 10/15/2023] [Accepted: 11/07/2023] [Indexed: 03/17/2024]
Abstract
BACKGROUND A novel hydrophobically modified chitosan (hm-chitosan) polymer has been previously shown to improve survival in a non-compressible intra-abdominal bleeding model in swine. We performed a 28-day survival study to evaluate the safety of the hm-chitosan polymer in swine. METHODS Female Yorkshire swine (40-50 kg) were used. A mild, non-compressible, closed-cavity bleeding model was created with splenic transection. The hm-chitosan polymer was applied intra-abdominally through an umbilical nozzle in the same composition and dose previously shown to improve survival. Animals were monitored intraoperatively and followed 28 days postoperatively for survival, signs of pain, and end-organ function. Gross pathological and microscopic evaluations were performed at the conclusion of the experiment. RESULTS A total of 10 animals were included (hm-chitosan = 8; control = 2). The 2 control animals survived through 28 days, and 7 of the 8 animals from the hm-chitosan group survived without any adverse events. One animal from the hm-chitosan group required early termination of the study for signs of pain, and superficial colonic ulcers were found on autopsy. Laboratory tests showed no signs of end-organ dysfunction after exposure to hm-chitosan after 28 days. On gross pathological examination, small (<0.5 cm) peritoneal nodules were noticed in the hm-chitosan group, which were consistent with giant-cell foreign body reaction in microscopy, presumably related to polymer remnants. Microscopically, no signs of systemic polymer embolization or thrombosis were noticed. CONCLUSION Prolonged intraperitoneal exposure to the hm-chitosan polymer was tolerated without any adverse event in the majority of animals. In the single animal that required early termination, the material did not appear to be associated with end-organ dysfunction in swine. Superficial colonic ulcers that would require surgical repair were identified in 1 out of 8 animals exposed to hm-chitosan.

Abstract
Developing hydrogels that can quickly reach deep bleeding sites, adhere to wounds, and expand to stop lethal and/or noncompressible bleeding in civil and battlefield environments remains a challenge. Herein, an injectable, antibacterial, self-expanding, and self-propelling hydrogel bioadhesive with procoagulant activity and rapid gelation is reported. This hydrogel combines spontaneous gas foaming and rapid Schiff base crosslinking for lethal massive hemorrhage. Hydrogels have rapid gelation and expansion rate, high self-expanding ratio, excellent antibacterial activity, antioxidant efficiency, and tissue adhesion capacity. In addition, hydrogels have good cytocompatibility, procoagulant ability, and higher blood cell/platelet adhesion activity than commercial combat gauze and gelatin sponge. The optimized hydrogel (OD-C/QGQL-A30) exhibits better hemostatic ability than combat gauze and gelatin sponge in rat liver and femoral artery bleeding models, rabbit volumetric liver loss massive bleeding models with/without anticoagulant, and rabbit liver and kidney incision bleeding models with bleeding site not visible. Especially, OD-C/QGQL-A30 rapidly stops the bleedings from pelvic area of rabbit, and swine subclavian artery vein transection. Furthermore, OD-C/QGQL-A30 has biodegradability and biocompatibility, and accelerates Methicillin-resistant S. aureus (MRSA)-infected skin wound healing. This injectable, antibacterial, self-expanding, and self-propelling hydrogel opens up a new avenue to develop hemostats for lethal massive bleeding, abdominal organ bleeding, and bleeding from coagulation lesions.

Abstract
INTRODUCTION Traumatic hemorrhage is a leading cause of preventable mortality worldwide. The Stop the Bleed (STB) course was developed to equip layperson bystanders with basic bleeding control knowledge and skills. However, large in-person courses have been disrupted due to COVID-19. The aim of this study was to determine the feasibility of teaching and evaluating STB skills through remote video-based instruction. METHODS After undergoing COVID-19 screening, groups of up to eight STB-naive adults were seated in a socially distanced manner and given individual practice kits. A remote STB-certified instructor provided the standard STB lecture and led a 10-min skills practice session via videoconferencing. Participants' skills were evaluated on a 10-point rubric by one in-person evaluator and three remote evaluators. Participants completed a postcourse survey assessing their perceptions of the course. RESULTS Thirty-five participants completed the course, all scoring ≥8/10 after examination by the in-person evaluator. Remote instructors' average scores (9.8 ± 0.45) did not significantly differ from scores of the in-person evaluator (9.9 ± 0.37) (P = 0.252). Thirty-three participants (94%) completed the postcourse survey. All respondents reported being willing and prepared to intervene in scenarios of life-threatening hemorrhage, and 97% reported confidence in using all STB skills. CONCLUSIONS STB skills can be effectively taught and evaluated through a live video-based course. All participants scored highly when evaluated both in-person and remotely, and nearly all reported confidence in skills and knowledge following the course. Remote instruction is a valuable strategy to disseminate STB training to students without access to in-person courses, especially during pandemic restrictions.

Predictors of Short-Term Trauma Laparotomy Outcomes in an Integrated Military-Civilian Health System: A 23-Year Retrospective Cohort Study. J Clin Med 2024; 13:1830. [PMID: 38610595 PMCID: PMC11012665 DOI: 10.3390/jcm13071830] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2024] [Revised: 02/03/2024] [Accepted: 03/14/2024] [Indexed: 04/14/2024] Open
Abstract
Background: Trauma laparotomy (TL) remains a cornerstone of trauma care. We aimed to investigate prehospital measures associated with in-hospital mortality among casualties subsequently undergoing TLs in civilian hospitals. Methods: This retrospective cohort study cross-referenced the prehospital and hospitalization data of casualties treated by Israel Defense Forces-Medical Corps teams who later underwent TLs in civilian hospitals between 1997 and 2020. Results: Overall, we identified 217 casualties treated by IDF-MC teams that subsequently underwent a TL, with a mortality rate of 15.2% (33/217). The main mechanism of injury was documented as penetrating for 121/217 (55.8%). The median heart rate and blood pressure were within the normal limit for the entire cohort, with a low blood pressure predicting mortality (65 vs. 127, p < 0.001). In a multivariate analysis, prehospital endotracheal intubation (ETI), emergency department Glasgow coma scores of 3-8, and the need for a thoracotomy or bowel-related procedures were significantly associated with mortality (OR 6.8, p < 0.001, OR = 48.5, p < 0.001, and OR = 4.61, p = 0.002, respectively). Conclusions: Prehospital interventions introduced throughout the study period did not lead to an improvement in survival. Survival was negatively influenced by prehospital ETI, reinforcing previous observations of the potential deleterious effects of definitive airways on hemorrhaging trauma casualties. While a low blood pressure was a predictor of mortality, the median systolic blood pressure for even the sickest patients (ISS > 16) was within normal limits, highlighting the challenges in triage and risk stratification for trauma casualties.

Abstract
Since limb bleeding has been well managed by extremity tourniquets, the management of exsanguinating torso hemorrhage (TH) has become a hot issue both in military and civilian medicine. Conventional hemostatic techniques are ineffective for managing traumatic bleeding of organs and vessels within the torso due to the anatomical features. The designation of noncompressible torso hemorrhage (NCTH) marks a significant step in investigating the injury mechanisms and developing effective methods for bleeding control. Special tourniquets such as abdominal aortic and junctional tourniquet and SAM junctional tourniquet designed for NCTH have been approved by FDA for clinical use. Combat ready clamp and junctional emergency treatment tool also exhibit potential for external NCTH control. In addition, resuscitative endovascular balloon occlusion of the aorta (REBOA) further provides an endovascular solution to alleviate the challenges of NCTH treatment. Notably, NCTH cognitive surveys have revealed that medical staff have deficiencies in understanding relevant concepts and treatment abilities. The stereotypical interpretation of NCTH naming, particularly the term noncompressible, is the root cause of this issue. This review discusses the dynamic relationship between TH and NCTH by tracing the development of external NCTH control techniques. The authors propose to further subdivide the existing NCTH into compressible torso hemorrhage and NCTH' (noncompressible but REBOA controllable) based on whether hemostasis is available via external compression. Finally, due to the irreplaceability of special tourniquets during the prehospital stage, the authors emphasize the importance of a package program to improve the efficacy and safety of external NCTH control. This program includes the promotion of tourniquet redesign and hemostatic strategies, personnel reeducation, and complications prevention.

Abstract
Background Non-compressible abdominal hemorrhage (NCAH) is the leading cause of potentially preventable deaths in both civilian and military austere environments, and an improvement in mortality due to this problem has not been demonstrated during the past quarter century. Several innovations have been developed to control hemorrhage closer to the point of injury. Objective This review assessed NCAH interventions in civilian and military settings, focusing on austere environments. It identified innovations, effectiveness, and knowledge gaps for future research. Methodology The Joanna Briggs Institute for Evidence Synthesis methodology guided this scoping review to completion. Studies evaluating NCAH with human participants in civilian and military austere environments that were eligible for inclusion were limited to English language studies published between December 1990 and January 2023. The PCC (Participant, Concept, Context) framework was used for data synthesis. Deductive and inductive thematic analyses were used to assess the literature that met inclusion criteria, identify patterns/themes to address the research questions and identify common themes within the literature. A stakeholder consultation was conducted to review and provide expert perspectives and opinions on the results of the deductive and inductive thematic analyses. Results The literature search identified 868 articles; 26 articles met the inclusion criteria. Textual narrative analysis of the 26 articles resulted in the literature addressing four main categories: NCAH, penetrating abdominal trauma, resuscitative endovascular balloon occlusion of the aorta (REBOA), and ResQFoam. The deductive thematic analysis aimed to answer three research questions. Research question 1 addressed the effectiveness of REBOA, damage control resuscitation, and damage control surgery in managing NCAH in austere environments. No effectiveness studies were found on this topic. Research question 2 identified three knowledge gaps in NCAH management in austere environments. The analysis identified early hemorrhage control, prehospital provider decision-making ability, and REBOA implementation as knowledge gaps in NCAH. Research question 3 identified five innovations that may affect the management of NCAH in the future: transport of patients, advanced resuscitative care, expert consultation, REBOA implementation, and self-expanding foam implementation. The inductive thematic analysis resulted in four recurrent themes from the literature: prehospital care, decision-making, hemorrhage control, and mortality in NCAH. During the stakeholders' consultation, the results of the deductive and inductive thematic analyses were reviewed and agreed on by the stakeholders. Special emphasis and discussion were given to prehospital management, expert opinions in the prehospital environment, decision-making in the prehospital environment, transport and resuscitation in the prehospital setting, REBOA, alternative discussion for research, and research gaps. Conclusion NCAH is still a significant cause of preventable death in both military and civilian austere environments, even with ongoing research and interventions aimed at extending survival in such conditions. This scoping review has identified several potential concepts that could reduce the mortality associated with a preventable cause of death due to hemorrhage in austere environments.

Abstract
Hemorrhage is the leading cause of preventable death in both civilian and military medicine. Junctional hemorrhages are especially difficult to manage since traditional tourniquet placement is often not possible. Ultrasound can be used to visualize and guide the caretaker to apply pressure at physiological pressure points to stop hemorrhage. However, this process is technically challenging, requiring the vessel to be properly positioned over rigid boney surfaces and applying sufficient pressure to maintain proper occlusion. As a first step toward automating this life-saving intervention, we demonstrate an artificial intelligence algorithm that classifies a vessel as patent or occluded, which can guide a user to apply the appropriate pressure required to stop flow. Neural network models were trained using images captured from a custom tissue-mimicking phantom and an ex vivo swine model of the inguinal region, as pressure was applied using an ultrasound probe with and without color Doppler overlays. Using these images, we developed an image classification algorithm suitable for the determination of patency or occlusion in an ultrasound image containing color Doppler overlay. Separate AI models for both test platforms were able to accurately detect occlusion status in test-image sets to more than 93% accuracy. In conclusion, this methodology can be utilized for guiding and monitoring proper vessel occlusion, which, when combined with automated actuation and other AI models, can allow for automated junctional tourniquet application.

Vrancken SM, de Vroome M, van Vledder MG, Halm JA, Van Lieshout EMM, Borger van der Burg BLS, Hoencamp R, Verhofstad MHJ, van Waes OJF. Non-compressible truncal and junctional hemorrhage: A retrospective analysis quantifying potential indications for advanced bleeding control in Dutch trauma centers. Injury 2024; 55:111183. [PMID: 37981519 DOI: 10.1016/j.injury.2023.111183] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/21/2023] [Revised: 10/06/2023] [Accepted: 11/03/2023] [Indexed: 11/21/2023]
Abstract
BACKGROUND Truncal and junctional hemorrhage is the leading cause of potentially preventable deaths in trauma patients. To reduce this mortality, the application of advanced bleeding control techniques, such as resuscitative endovascular balloon occlusion of the aorta (REBOA), junctional tourniquets, Foley catheters, or hemostatic agents should be optimized. This study aimed to identify trauma patients with non-compressible truncal and junctional hemorrhage (NCTJH) who might benefit from advanced bleeding control techniques during initial trauma care. We hypothesized that there is a substantial cohort of Dutch trauma patients that can possibly benefit from advanced bleeding control techniques. METHODS Adult trauma patients with an Abbreviated Injury Scale ≥3 in the torso, neck, axilla, or groin region, who were presented between January 1st, 2014 and December 31st, 2018 to two Dutch level-1 trauma centers, were identified from the Dutch Trauma Registry. Potential indications for advanced bleeding control in patients with NCTJH were assessed by an expert panel of three trauma surgeons based on injury characteristics, vital signs, response to resuscitation, and received treatment. RESULTS In total, 1719 patients were identified of whom 249 (14.5 %) suffered from NCTJH. In 153 patients (60.6 %), hemorrhagic shock could have been mitigated or prevented with advanced bleeding control techniques. This group was younger and more heavily injured: median age of 40 versus 48 years and median ISS 33 versus 22 as compared to the entire cohort. The mortality rate in these patients was 31.8 %. On average, each of the included level-1 trauma centers treated an NCTJH patient every 24 days in whom a form of advanced bleeding control could have been beneficial. CONCLUSIONS More than half of included Dutch trauma patients with NCTJH may benefit from in-hospital application of advanced bleeding control techniques, such as REBOA, during initial trauma care. Widespread implementation of these techniques in the Dutch trauma system may contribute to reduction of mortality and morbidity from non-compressible truncal and junctional hemorrhage.

JOURNAL OF SURGICAL EDUCATION 2023; 80:1320-1339. [PMID: 37516576 DOI: 10.1016/j.jsurg.2023.06.018] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/14/2023] [Revised: 05/11/2023] [Accepted: 06/17/2023] [Indexed: 07/31/2023]
Abstract
INTRODUCTION Live anaesthetized animals are used as simulation models to teach techniques in the emergency management of trauma. We aimed to explore how "live tissue training" (LTT) is designed, delivered and evaluated in order to better understand and characterize aspects of educational merit. METHODS A systematic review was performed using PRISMA guidance. A combined approach, involving a 3-stage modified narrative synthesis process and reflexive thematic analysis was used to identify key concepts across the published literature. FINDINGS Qualitative synthesis of 48 selected articles suggests that LTT is mainly used to teach military and civilian physicians and military medical technicians. The procedures trained vary with the learner population, from simple pre-hospital trauma tasks to advanced operative surgical skills. Many courses use a combination of didactic and practical training, with an animal model used to train practical application of knowledge and procedural skills. Descriptions of the learning interventions are limited, and explicit use of educational theory or pedagogic frameworks were absent within the literature. Four themes were identified regarding aspects of LTT that are valued by learners: "recreating the experience," relating to fidelity and realism; "tick tock" "dynamics of hemorrhage", encompassing the impact of bleeding and urgent pressure to act; "emotional impact" of conducting the training, and "self-efficacy: I believe I can do it." CONCLUSION Thematic analysis of published literature suggests that there may be educational benefit in the use of live tissue models due to time criticality and bleeding, which creates a real-life event. LTT also invokes an emotional response, and learners experience an increase in self-efficacy from participation. We consider that these aspects and associated pedagogy should be addressed when researching and developing alternative simulation modalities, in order to intelligently replace, reduce and refine the use of animals in training practitioners in the emergency management of trauma.

Abstract
BACKGROUND Control of massive hemorrhage from penetrating wound sites is difficult in both combat and civilian settings. A new hemostatic dressing, sodium polyacrylate (PAAs)-based bag (PB), based on PAAs is designed for the first aid of massive penetrating hemorrhage. This study aimed to investigate the efficacy of PB in a penetrating trauma model in swine. METHODS A complex groin penetrating injury was produced in swine by completely excising the femoral vessels and surrounding muscles. After 15-second free bleeding, 18 healthy Guizhou female swine were administered PB (n = 6), CELOX-A (n = 6; Medtrade Products, Crewe, United Kingdom), or standard gauze (n = 6) for hemostatic intervention, followed by 3-minute compression if the bleeding persisted, with subsequent observation continuing for 1 hour. The primary outcomes included initial hemostasis, the incidence of applying manual pressure, and application time. RESULTS Sodium polyacrylate could rapidly absorb the liquid to expand, crosslink with a large number of red blood cells, induce cellular morphological alteration, and promote blood coagulation. Sodium polyacrylate-based bag and CELOX-A initiated and sustained hemostasis for 60 minutes, whereas 0% of the standard gauze achieved initial hemostasis. Maximum number of manual compressions were applied in standard gauze (6 of 6 [100%]), followed by CELOX-A (5 of 6 [80%]), while no manual pressure was required in the case of PB (0 of 6 [0%]). Application time for PB (19.0 ± 4.6 seconds) was significantly less than CELOX-A (169.0 ± 73.5 seconds) and standard gauze (187.8 ± 1.7 seconds). CONCLUSION We prepared a type of superabsorbent PAAs and made an original hemostatic dressing, PB. It can rapidly achieve durable hemostasis in the groin-penetrating trauma hemorrhage swine model without any external compression. The packet form makes PB easy to deploy and remove from wounds. Therefore, PB could be a promising hemostatic candidate for controlling penetrating hemorrhage.

Abstract
LAY SUMMARY The efficacy of current hemostatic technologies is limited by several factors. Outward blood flow washes hemostatic drugs away from the wound, and hemostatic drugs often require focus, training, and time to use correctly, are highly specific to one type of injury, or pose severe safety risks. CounterFlow is a novel product that could potentially save military and civilian lives by stopping heavy bleeding from a variety of organs and other bodily locations that current technology cannot easily treat. Upon contact with blood, CounterFlow releases bursts of gas to safely self-propel bio-degradable clot-forming and clot-stabilizing drugs against blood flow, delivering them to the source of bleeding. This unique mechanism allows CounterFlow to be applied quickly to a wide assortment of wounds and to act effectively with little management after application. CounterFlow was tested in multiple animal models representing common and deadly bleeding scenarios, including internal bleeding, care under fire without compression, and surgical bleeding, and it was found to outperform current care options by stopping bleeds faster and increasing survival times. CounterFlow is also safe to use and biocompatible. This narrative review summarizes studies testing the effectiveness and safety of CounterFlow, discusses useful applications, and describes future plans for the product.

Abstract
INTRODUCTION While the pressure points technique for proximal hemorrhage control is long known, it is not recommended in standard prehospital guidelines based on a study showing the inability to maintain occlusion for over two minutes. MAIN SYMPTOM This report details a gunshot wound to the left axillary area with complete transection of the axillary artery, leading to profuse junctional hemorrhage and profound hemorrhagic shock. THERAPEUTIC INTERVENTION Proximal pressure of the subclavian artery was applied against the first rib (the pressure points technique) and maintained for 28 minutes. OUTCOMES Cessation of apparent bleeding and excellent, enduring physiologic response to blood transfusion were observed. CONCLUSION The pressure points technique can be life-saving in junctional arterial hemorrhage and should be reconsidered in prehospital guidelines.

Abstract
BACKGROUND Hemorrhage from truncal and junctional injuries is responsible for the vast majority of potentially survivable deaths in combat casualties, causing most of its fatalities in the prehospital arena. Optimizing the deployment of the advanced bleeding control modalities required for the management of these injuries is essential to improve the survival of severely injured casualties. This study aimed to establish consensus on the optimal use and implementation of advanced bleeding control modalities in combat casualty care. METHODS A Delphi method consisting of three rounds was used. An international expert panel of military physicians was selected by the researchers to complete the Delphi surveys. Consensus was reached if 70% or greater of respondents agreed and if 70% or greater responded. RESULTS Thirty-two experts from 10 different nations commenced the process and reached consensus on which bleeding control modalities should be part of the standard equipment, that these modalities should be available at all levels of care, that only trained physicians should be allowed to apply invasive bleeding control modalities, but all medical and nonmedical personnel should be allowed to apply noninvasive bleeding control modalities, and on the training requirements for providers. Consensus was also reached on the necessity of international registries and guidelines, and on certain indications and contraindications for resuscitative endovascular balloon occlusion of the aorta (REBOA) in military environments. No consensus was reached on the role of a wound clamp in military settings and the indications for REBOA in patients with chest trauma, penetrating axillary injury or penetrating neck injury in combination with thoracoabdominal injuries. CONCLUSION Consensus was reached on the contents of a standard bleeding control toolbox, where it should be available, providers and training requirements, international registries and guidelines, and potential indications for REBOA in military environments.

Abstract
Excessive bleeding has always been of great medical challenge, particularly in trauma and surgery. Due to the fast clearance of medicine and complex hemodynamics during hemorrhage, it is often difficult to achieve rapid and effective hemostasis on irregularly shaped, noncompressible visceral bleeding wounds. Herein, we report a hemostatic derived from supramolecularly functionalized platelets (SPLTs), showing rapid hemorrhage controlling effects via efficiently targeting injured vessels and in-situ aggregation. Von Willebrand factor-binding peptide (VBP) modified hyaluronic acid (HA-VBP) decorated platelets (PLTs) were fabricated via supramolecular host-guest interactions between cucurbit[7]uril (CB[7], a host molecule) modified on HA-VBP (HA-CB[7]-VBP) and adamantane (ADA, a guest molecule) anchored on the surface of PLTs (ADA-PLTs). The SPLTs demonstrated approximately 10-fold improvements than the native PLTs in the targeting efficiency into the injured vessels in mice upon intravenous injection. More significantly, the total bleeding time and bleeding volume were dramatically reduced down to less than 1/4 and 1/10 of the control group, respectively, in both external and internal major bleeding mice models. This SPLTs provide a facile yet effective approach for rapid control of major hemorrhage and offers important new insights to the design and development PLTs-based hemostatics. STATEMENT OF SIGNIFICANCE: Hemorrhage is one of the greatest threats to humans in trauma and surgery. To reduce bleeding volume and time, transfusion of hematological products such as platelets (PLTs)-rich plasma is one of the most commonly used therapeutics, but with low targeting and hemostatic efficiency. Thus, engineered PLTs with expanded structural repertoire and functionalities are in urgent clinical needs. Herein, we developed supramolecularly functionalized PLTs (SPLTs), prepared with a mild and facile approach, for rapid control of hemorrhage with significantly enhanced targeting efficiency. The SPLTs not only provide a facile approach for rapid control of major hemorrhage, but also offer important new insights into the development PLTs-based hemostatics.

Percutaneous delivery of self-propelling hemostatic powder for managing non-compressible abdominal hemorrhage: a proof-of-concept study in swine. Injury 2022; 53:1603-1609. [PMID: 35067343 DOI: 10.1016/j.injury.2022.01.024] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/30/2021] [Revised: 12/23/2021] [Accepted: 01/12/2022] [Indexed: 02/02/2023]
Abstract
INTRODUCTION Non-compressible intra-abdominal hemorrhage (NCIAH) is a major cause of preventable death on the battlefield and in civilian trauma. Currently, it can only be definitively managed with surgery, as there are limited strategies for controlling ongoing NCIAH in the prehospital environment. We hypothesized that a self-propelling thrombin-containing powder (SPTP) could increase survival in a swine model of NCIAH when delivered percutaneously into the closed abdomen using an engineered spray system. MATERIALS AND METHODS Nineteen swine underwent surgical laparotomy followed by a Grade V liver injury that created massive hemorrhage, before closing the abdomen with sutures. Animals either received treatment with standard of care fluid resuscitation (n=9) or the SPTP spray system (n=10), which consisted of a spray device and a 14 Fr catheter. Using the spray system, SPTP was delivered into a hemoperitoneum identified using a focused assessment with sonography in trauma (FAST) exam. Lactated Ringer's solution was administered to all animals to maintain a mean arterial pressure (MAP) of >50 mmHg. The primary outcome was percentage of animals surviving at three hours following injury. RESULTS In the swine model of NCIAH, a greater percentage of animals receiving SPTP survived to three hours, although differences were not significant. The SPTP spray system increased the median survival of animals from 1.6 hr in the fluid resuscitation group to 4.3 hr. The SPTP spray system delivered a total mass of 18.5 ± 1.0 g of SPTP. The mean change in intra-abdominal pressure following SPTP delivery was 5.2 ± 1.8 mmHg (mean ± SEM). The intervention time was 6.7 ± 1.7 min. No adverse effects related to the SPTP formulation or the spray system were observed. SPTP was especially beneficial in animals that had either severely elevated lactate concentrations or low mean arterial pressure of <35 mmHg shortly after injury. CONCLUSIONS This demonstrates proof-of-concept for use of a new minimally invasive procedure for managing NCIAH, which could extend survival time to enable patients to reach definitive surgical care.

Abstract
Uncontrolled hemorrhage is a leading cause of death in trauma situations. Developing solutions to automate hemorrhagic shock resuscitation may improve the outcomes for trauma patients. However, testing and development of automated solutions to address critical care interventions, oftentimes require extensive large animal studies for even initial troubleshooting. The use of accurate laboratory or in-silico models may provide a way to reduce the need for large animal datasets. Here, a tabletop model, for use in the development of fluid resuscitation with physiologically relevant pressure-volume responsiveness for high throughput testing, is presented. The design approach shown can be applied to any pressure-volume dataset through a process of curve-fitting, 3D modeling, and fabrication of a fluid reservoir shaped to the precise curve fit. Two case studies are presented here based on different resuscitation fluids: whole blood and crystalloid resuscitation. Both scenarios were derived from data acquired during porcine hemorrhage studies, used a pressure-volume curve to design and fabricate a 3D model, and evaluated to show that the test platform mimics the physiological data. The vessels produced based on data collected from pigs infused with whole blood and crystalloid were able to reproduce normalized pressure-volume curves within one standard deviation of the porcine data with mean residual differences of 0.018 and 0.016, respectively. This design process is useful for developing closed-loop algorithms for resuscitation and can simplify initial testing of technologies for this life-saving medical intervention.

Use of Haemostatic Devices for the Control of Junctional and Abdominal Traumatic Haemorrhage: A Systematic Review. TRAUMA CARE 2022.

Abstract
Catastrophic haemorrhage accounts for up to 40% of global trauma related mortality and is the leading cause of preventable deaths on the battlefield. Controlling abdominal and junctional haemorrhage is challenging, especially in the pre-hospital setting or ‘under fire’, yet there is no haemostatic agent which satisfies the seven characteristics of an ‘ideal haemostat’. We conducted a systematic search of Embase, Medline, Cumulative Index to Nursing and Allied Health Literature (CINAHL), and Web of Science to evaluate the feasibility and efficacy of three types of haemostatic devices. Participants included any trauma patient in a pre-hospital setting, perfused human cadavers, or healthy human volunteer simulations. The haemostatic devices reviewed were REBOA, iTClampTM, and four junctional tourniquets: AAJT, CRoC, JETT, and SJT. The SJT had the best user survey performance of the junctional tourniquets, and the four junctional tourniquets had an overall efficacy of 26.6–100% and an application time of 10–203 s. The iTClampTM had an efficacy of 60–100% and an application time of 10–60 s. REBOA had an efficacy of 71–100% and an application time ranging from 5 min to >80 min. In civilian and military trauma patients the use of junctional tourniquets, iTClamp, or REBOA, mortality varied from 0–100%. All of these studies were deemed low to very low in quality, hence the reliability of data presented in each of the studies is called into question. We conclude that despite limited data for these devices, their use in the pre-hospital environment or ‘under fire’ is feasible with the correct training, portable imaging, and patient selection algorithms. However, higher quality studies are required to confirm the true efficacy of these devices.

Abstract
Hemorrhage, and particularly noncompressible torso hemorrhage remains a leading cause of potentially preventable prehospital death from trauma in the United States and globally. A subset of severely injured patients either die in the field or develop irreversible hemorrhagic shock before they can receive hospital definitive care, resulting in poor outcomes. The focus of this opinion paper is to delineate (a) the need for existing trauma systems to adapt so that potentially life-saving advanced resuscitation and truncal hemorrhage control interventions can be delivered closer to the point-of-injury in select patients, and (b) a possible mechanism through which some trauma systems can train and incorporate select prehospital advanced resuscitative care teams to deliver those interventions.

Abstract
OBJECTIVES Uncontrolled bleeding is the leading cause of preventable death after a traumatic event, and early intervention to control bleeding improves opportunities for survival. It is imperative to prepare for local and national disasters by increasing public knowledge on how to control bleeding, and this preparation should extend to both adults and children. The purpose of this study is to describe a training effort to teach basic hemorrhage control techniques to early adolescent children. METHODS The trauma and emergency departments at a combined level I adult and level II pediatric trauma center piloted a training initiative with early adolescents (grades 6-8) focused on 2 skills: packing a wound and holding direct pressure, and applying a Combat Application Tourniquet. Students were evaluated on each skill and completed presurveys and postsurveys indicating their likelihood to use the skills. RESULTS Of the 194 adolescents who participated in the trainings, 97% of the students could successfully pack a wound and hold pressure, and 97% of the students could apply a tourniquet. Before the training, 71% of the adolescents indicated that they would take action to assist a bleeding victim; this increased to 96% after the training. CONCLUSIONS Results demonstrate that basic hemorrhage control skills can be effectively taught to adolescents as young as 6th grade (ages 11-12 years) in a small setting with age-appropriate content and hands-on opportunities to practice the skills and such training increases students' perceived willingness to take action to assist a bleeding victim.

Abstract
Hemostatic agents are pivotal for managing clinical and traumatic bleeding during emergency and domestic circumstances. Herein, a novel functional hybrid nanocomposite material consisting of plasma polymer-modified zeolite 13X and ultra-small gold nanoclusters (AuNCs) was fabricated as an efficient hemostatic agent. The surface of zeolite 13X was functionalised with amine groups which served as binding sites for carboxylate terminated AuNCs. Protein corona studies revealed the enhanced adsorption of two proteins, namely, coagulation factors and plasminogen as a result of AuNCs immobilization on the zeolite surface. The immune response studies showed that the hybrid nanocomposites are effective in reducing inflammation, which combined with a greater attachment of vitronectin, may promote wound healing. The hemostatic potential of the nanocomposite could be directly correlated with their immunomodulatory and anti-haemorrhagic properties. Together, the hybrid nanoengineered material developed in this work could provide a new avenue to tackle life-threatening injuries in civilian and other emergencies.

Abstract
External aortic compression has been investigated as a treatment for non-compressible truncal haemorrhage in trauma patients. We sought to systematically gather and tabulate the available evidence around external aortic compression. We were specifically interested in its ability to achieve hemostasis and aid in resuscitation of traumatic arrest and severe shock and to consider physiological changes and adverse effects. A scoping review approach was chosen due to the highly variable existing literature. We were guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses, using the specific extension for scoping reviews. Searches were done on PubMed and Scopus databases in October 2020. We found that a range of studies have investigated external aortic compression in a variety of settings, including case reports and small case series, porcine hemorrhage models and effects on healthy volunteers. External aortic compression for postpartum hemorrhage in a single center provided some evidence of effectiveness. Overall the level of evidence is limited, however, external aortic compression does appear able to achieve cessation of distal blood flow. Furthermore, it appears to improve many relevant physiological parameters in the setting of hypovolemic shock. Application for more than 60 minutes appears to cause increasingly problematic complications. In conclusion we find that the role of external aortic compression warrants further research. The intervention may have a role as a bridge to definitive treatment of noncompressible truncal haemorrahge.

Abstract
Penetrating injuries to the neck pose a unique challenge to clinicians due to the proximity of multiple significant anatomical structures with little protective soft tissue coverage. Injuries to this area, whilst low in incidence, are potentially devastating. Respiratory, vascular, gastro-oesophageal and neurological structures may all be involved, either in isolation or combination. These injuries are particularly difficult to manage in the resource poor, often austere and/or remote, pre-hospital environment. A systematic scoping review of the literature was conducted to evaluate the current available research pertaining to managing this injury profile, prior to the patient arriving in the emergency department. The available research is discussed in sections based on the commonly used trauma management acronym ‘cABCD’ (catastrophic haemorrhage, Airway, Breathing, Circulation, Disability) to facilitate a systematic approach and clinical evaluation familiar to clinicians. Based on the available reviewed evidence, we have proposed a management algorithm for this cohort of patients. From this we plan to instigate a Delphi process to develop a consensus statement on the pre-hospital management of this challenging presentation.

Abstract
INTRODUCTION Penetrating trauma is commonly seen in dogs. The severity depends on the site of injury and tissue involved. Junctional hemorrhage can be especially challenging to control given the inaccessibility of the damaged vasculature. Methods described to control life-threatening hemorrhage in dogs include direct pressure, hemostatic gauze, hemostatic powder or granules, wound packing, tourniquets, and direct clamping of the vasculature. Foley balloon catheters (FBC) are commonly used to tamponade deep vascular hemorrhage in people, but the technique has not been previously described in the veterinary literature. OBJECTIVE To present a case of penetrating trauma (bite wound) in a dog with a transected left femoral artery and vein in which the life-threatening hemorrhage was initially controlled with tamponade using an FBC. CASE A 7-year-old neutered male Terrier mix presented in hemorrhagic shock with an Animal Trauma Triage (ATT) of 7 and modifed Glasgow coma scale (MGCS) of 17 forty-five minutes after being attacked by another dog. The dog had sustained a deep penetrating wound to the left groin. Direct pressure and gauze packing at the site of injury were not successful at slowing the hemorrhage. A 10-Fr, 55-cm Foley catheter with a 5-mL balloon was inserted into the wound tract, and the balloon was inflated with 7.5 mL of sterile saline. Hemorrhage was controlled after inflation of the Foley balloon. CBC, blood biochemistries, abdominal point-of-care ultrasound, radiographs, prothrombin time, partial thromboplastin time, and whole blood viscoelastic testing were performed. Stabilization included fluid resuscitation, analgesics, antimicrobials, and epsilon aminocaproic acid. The dog was then anesthetized to definitively identify and control the hemorrhage. Transection of the left femoral artery and vein where identified and ligated. The dog fully recovered and was discharged 32 hours later. NEW AND UNIQUE INFORMATION FBCs may be useful as an alternative technique for temporary control of life-threatening hemorrhage secondary to penetrating injuries in both the emergency department and prehospital settings.

Abstract
In the United States, trauma claims the lives of over 150,000 civilians each year. In military settings, trauma and exsanguination result in 50% of combat related deaths. The majority of these deaths result from uncontrolled non-compressible hemorrhage. Non-compressible hemorrhage often results from deep vascular injuries within the torso, however can also occur secondary to penetrating injuries that involve the extremities. Given the high mortality rates for non-compressible hemorrhage, rapid and effective management of patients suffering from hemorrhage is essential to good patient outcomes. Consequently, there has been increasing interest in solutions for point-of-injury hemorrhage control in trauma and military medicine. Undoubtedly there is a great need for prehospital hemostatic interventions that can be deployed by trained and untrained personnel. Since 2001, various hemostatic agents have been developed, each with its advantages based upon the type and severity of injury, wound size, wound location, accessibility to injury site, and the coagulation status of the patient. These agents are often used in the military setting as a temporizing measure prior to definitive therapy and include techniques such as resuscitative endovascular balloon occlusion of the aorta (REBOA) and bioengineered agents including ResQFoam, RevMedx’s XSTAT, Tranexamic acid (TXA), and QuikClot Combat Gauze (QCG). Here, we review the indications, composition, technique, efficacy, and outcomes of these hemostatic agents.

[PMID: 34304008 DOI: 10.1016/j.jss.2021.06.052] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2020] [Revised: 05/14/2021] [Accepted: 06/21/2021] [Indexed: 11/25/2022]
Abstract
BACKGROUND Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) was developed to prevent traumatic exsanguination. We aim to identify the outcomes in animal models with 1) partial versus complete REBOA occlusion and 2) zone 1 versus 2 placements. METHODS The PRISMA guidelines were followed. We conducted a search of PubMed, EMBASE and Google Scholar for REBOA studies in animal trauma models using the following search terms: "REBOA trauma", "REBOA outcomes" "REBOA complications". SYRCLE's RoB Tool was utilized for the risk of bias and study quality assessment. RESULTS Our search yielded 14 RCTs for inclusion. Eleven studies directly investigated partial REBOA versus total aortic occlusion. Overall, partial REBOA techniques were associated with similar attainment of proximal MAP but with significantly less ischemic burden. Significant mortality benefit with partial occlusion was observed in three studies. Survival time post-occlusion also was improved with zone 3 placement versus zone 1 (100% versus 33%; P < 0.01). CONCLUSIONS There appears to be a fine balance between desired proximal arterial pressure and time of occlusion for overall survival and subsequent risk of distal ischemia. Many "partial occlusion" techniques may be superior in attaining such balance over prolonged REBOA inflation where no distal flow is allowed. Tailored zone 3 placement may offer significant mortality and morbidity advantages compared to sustained total occlusion and indiscriminate zone 1 placement strategies. As clear conclusions regarding REBOA are unlikely to be established in animal models, larger randomized investigations utilizing human subjects are needed to describe optimal REBOA technique and applicability in greater detail.

Abstract
Non-compressible hemorrhage in the junctional areas and torso could be life-threatening and its prehospital control remains extremely challenging. The aim of this review was to compare commonly used techniques for the control of non-compressible hemorrhage in prehospital settings, and thereby provide evidence for further improvements in emergency care of traumatic injuries. Three techniques were reviewed including external aortic compression (EAC), abdominal aortic junctional tourniquet (AAJT), and resuscitative endovascular balloon occlusion of the aorta (REBOA). In prehospital settings, all three techniques have demonstrated clinical effectiveness for the control of severe hemorrhage. EAC is a cost- and equipment-free, easy-to-teach, and immediately available technique. In contrast, AAJT and REBOA are expensive and require detailed instructions or systematic training. Compared with EAC, AAJT and REBOA have greater potentials in the management of traumatic hemorrhage. AAJT can be used not only in the junctional areas but also in pelvic and bilateral lower limb injuries. However, both AAJT and REBOA should be used for a limited time (less than 1 hour) due to possible consequences of ischemia and reperfusion. Compared with EAC and AAJT, REBOA is invasive, requiring femoral arterial access and intravascular guidance and inflation. Mortality from non-compressible hemorrhage could be reduced through the prehospital application of aortic blood flow control techniques. EAC should be considered as the first-line choice for many non-compressible injuries that cannot be managed with conventional junctional tourniquets. In comparison, AAJT or REBOA is recommended for better control of the aorta blood flow in prehospital settings. Although these three techniques each have advantages, their use in trauma is not widespread. Future studies are warranted to provide more data about their safety and efficacy.

Abstract
INTRODUCTION Prolonged field care for junctional wounds is challenging and involves limb movement to facilitate transport. No studies to date have explored the efficacy of gauze products to limit rebleeding in these scenarios. MATERIALS AND METHODS We randomly assigned 48 swine to QuikClot Combat Gauze, ChitoGauze, NuStat Tactical, or Kerlix treatment groups (12 each) and then inflicted a severe groin injury by utilizing a modified Kheirabadi model of a 6-mm femoral artery punch followed by unrestricted bleeding for 60 seconds. We reassessed rebleed following limb movement at 30 minutes of stabilization and 4 hours after stabilization. RESULTS Swine treated with Combat Gauze proved to have the lowest incidence of rebleeding, and conversely, NuStat Tactical had the highest incidence of rebleeding at wounds after limb movement. Importantly, rebleeds occurred at a rate of 25%-58% across all swine treatment groups at 30 minutes postinjury and 0%-42% at 270 minutes postinjury demonstrating that limb movements universally challenge hemostatic junctional wounds. CONCLUSIONS Our findings highlight the difficulty of controlling hemorrhage from junctional wounds with hemostatic gauze in the context of prolonged field care and casualty transport. Our research can guide selection of hemorrhage control gauze when patients have prolonged field extraction or difficult transport. Our data demonstrates the frequency of junctional wound rebleeding after movement and thus the importance of frequent patient reassessment.

Abstract
The peripheral arteries and veins of the extremities are among the most commonly injured vessels in both civilian and military vascular trauma. Blunt causes are more frequent than penetrating except during military conflicts and in certain geographic areas. Physical examination and simple bedside investigations of pulse pressures are key in early identification of these injuries. In stable patients with equivocal physical examinations, computed tomography angiograms have become the mainstay of screening and diagnosis. Immediate open surgical repair remains the first-line therapy in most patients. However, advances in endovascular therapies and more widespread availability of this technology have resulted in an increase in the range of injuries and frequency of utilization of minimally invasive treatments for vascular injuries in stable patients. Prevention of and early detection and treatment of compartment syndrome remain essential in the recovery of patients with significant peripheral vascular injuries. The decision to perform amputation in patients with mangled extremities remains difficult with few clear indicators. The American Association for the Surgery of Trauma in conjunction with the World Society of Emergency Surgery seeks to summarize the literature to date and provide guidelines on the presentation, diagnosis, and treatment of peripheral vascular injuries.

Abstract
BACKGROUND The data on resuscitative endovascular balloon occlusion of the aorta (REBOA) use continue to grow with its increasing use in trauma centers. The data in her last 5 years have not been systematically reviewed. We aim to assess current literature related to REBOA use and outcomes among civilian trauma populations. METHODS A literature search using PubMed, EMBASE, and JAMA Network for studies regarding REBOA usage in civilian trauma from 2016 to 2020 is carried out. This review followed preferred reporting items for systematic reviews and meta-analysis guidelines. RESULTS Our search yielded 35 studies for inclusion in our systematic review, involving 4073 patients. The most common indication for REBOA was patient presentation in hemorrhagic shock secondary to traumatic injury. REBOA was associated with significant systolic blood pressure improvement. Of 4 studies comparing REBOA to non-REBOA controls, 2 found significant mortality benefit with REBOA. Significant mortality improvement with REBOA compared to open aortic occlusion was seen in 4 studies. In the few studies investigating zone placement, highest survival rate was seen in patients undergoing zone 3. Overall, reports of complications directly related to overall REBOA use were relatively low. CONCLUSION REBOA has been shown to be effective in promoting hemodynamic stability in civilian trauma. Mortality data on REBOA use are conflicting, but most studies investigating REBOA vs. open occlusion methods suggest a significant survival advantage. Recent data on the REBOA technique (zone placement and partial REBOA) are sparse and currently insufficient to determine advantage with any particular variation. Overall, larger prospective civilian trauma studies are needed to better understand the benefits of REBOA in high-mortality civilian trauma populations. STUDY TYPE Systematic Review. LEVEL OF EVIDENCE III- Therapeutic.

Abstract
BACKGROUND External hemorrhage control devices (EHCDs) are effective in reducing the death risk of noncompressible torso hemorrhage (NCTH), but the pressurized area is too large to prevent serious organ damage. This study aims to establish the surface localization strategy of EHCDs based on the anatomical features of NCTH-related arteries through CT images to facilitate the optimal design and application of EHCDs. METHODS Two hundred patients who underwent abdominal CT were enrolled. Anatomical parameters such as the length of the common iliac artery (CIA), the external iliac artery (EIA), and the common femoral artery were measured; positional relationships among the EHCD-targeted arteries, umbilicus, anterior superior iliac spine (ASIS), and pubic tubercle (PT) were determined. The accuracy of surface localization was verified by the 3D-printed mannequins of 20 real patients. RESULTS Aortic bifurcation (AB) was 7.5 ± 8.6 mm to the left of the umbilicus. The left CIA (left: 46.6 ± 16.0 mm vs. right: 43.3 ± 15.5 mm, P = .038) and the right EIA (left: 102.6 ± 16.3 mm vs. right: 111.5 ± 18.8 mm, P < .001) were longer than their counterparts, respectively. The vertical distance between the CIA terminus and the ipsilateral AB-ASIS line was 19.6 ± 8.2 mm, and the left and right perpendicular intersections were located at the upper one-third and one-fourth of the AB-ASIS line, respectively. The length ratio of EIA-ASIS to ASIS-PT was 0.6:1. The predicted point and its actual subpoint were significantly correlated (P ≤ .002), and the vertical distance between the two points was ≤5.5 mm. CONCLUSION The arterial localization strategy established via anatomical investigation was consistent with the actual situation. The data are necessary for improving EHCD design, precise hemostasis, and EHCD-related collateral injuries.Trial registration: Ratification no. 2019092.

Abstract
In continued support of establishing and maintaining a foundation for standards of care, our organizations remain committed to periodic review and revision of this position statement. This latest revision was created based on a structured review of the National Model EMS Clinical Guidelines Version 2.2 in order to identify the equipment items necessary to deliver the care defined by those guidelines. In addition, in order to ensure congruity with national definitions of provider scope of practice, the list is differentiated into BLS and ALS levels of service utilizing the National Scope of Practice-defined levels of Emergency Medical Responder (EMR) and Emergency Medical Technician (EMT) as BLS, and Advanced EMT (AEMT) and Paramedic as ALS. Equipment items listed within each category were cross-checked against recommended scopes of practice for each level in order to ensure they were appropriately dichotomized to BLS or ALS levels of care. Some items may be considered optional at the local level as determined by agency-defined scope of practice and applicable clinical guidelines. In addition to the items included in this position statement our organizations agree that all EMS service programs should carry equipment and supplies in quantities as determined by the medical director and appropriate to the agency's level of care and available certified EMS personnel and as established in the agency's approved protocols.

Abstract
BACKGROUND The aim of this study is to evaluate the feasibility of en-route resuscitative endovascular balloon occlusion of the aorta (REBOA) on board of a helicopter. METHODS Six sedated male sheep (weighing 42-54 kg) underwent a controlled hemorrhage until the systolic blood pressure (BP) dropped to <90 mmHg, and were placed into a low capacity Eurocopter AS-350 (France). During the 30-minutes normal flight, every animal underwent blind (left side) and ultrasound-guided (US) (right side) vascular access (VA) to the femoral artery followed by REBOA: the first catheter (Rescue balloon, Japan) - into Zone I, the second one (MIT, Russia) - Zone III. In case of blind VA failure, an alternate US-puncture was attempted. Six experienced flight anesthetists were enrolled into the study. Vascular access and REBOA catheter placement (confirmed by X-Ray later) success rate and timing were recorded. RESULTS Among six blind punctures one was successful, 2/6 - were into the vein, 3/6 - completely failed and switched to US-punctures (making total number of US-punctures nine). Eight out of nine US-punctures were successful. However, correct wire insertion and sheath placement was performed in 1/6 animal in the 'blind' group and only in 6/9 animals in the 'US' group. It took a median of 65 seconds (range 5-260) for US-puncture and a median of 4 minutes to get the sheath in. Among the 9 VAs, there were 2 REBOA failures (1 ruptured balloon [MIT] and 1 mistaken vena cava placement primarily recognized by a sudden drop of BP and later confirmed by X-Ray). Five out of seven balloons were placed in a desired intra-aortic position: 4/5 in Zone I and 1/2 - in Zone III. A median time for a successful REBOA procedure was 5.0 (range 2.5-10.0) minutes (1 min after sheath placement). CONCLUSION Our study demonstrates the potential feasibility of the en-route REBOA which can be performed within 5 minutes. Ultrasound-guidance is critically important to achieve en-route VA.

Abstract
BACKGROUND Hemorrhage accounts for >30% of trauma-related mortalities. Use of resuscitative endovascular balloon occlusion of the aorta (REBOA) for temporary hemostasis in the civilian population remains controversial. We aim to investigate REBOA practices through analysis of surgeon and trauma center characteristics, implementation, patient characteristics, and overall opinions. METHODS An anonymous 30-question standardized online survey on REBOA use was administered to active trauma surgeon members of the Eastern Association for the Surgery of Trauma. RESULTS A total of 345 responses were received, and 130/345 (37.7%) reported REBOA being favorable, 42 (12.2%) reported REBOA unfavorably, and 173 (50.1%) were undecided. The majority of respondents (87.6%) reported REBOA performance in the trauma bay. 170 (49.3%) of respondents reported having deployed REBOA at least once over the past 2 years. 80.0% reported blunt trauma being the most common mechanism of injury in REBOA patients. Resuscitative endovascular balloon occlusion of the aorta deployment in zone 3 of the aorta was significantly higher in patients reported to suffer a pelvic fracture or pelvic hemorrhage, whereas REBOA deployment in zone 1 was significantly higher among patients reported to suffer hepatic, splenic, or other intra-abdominal hemorrhage (P < .05). CONCLUSION Among survey respondents, frequency of REBOA use was low along with knowledge of clear indications for use. While current REBOA usage among respondents appeared to model current guidelines, additional research regarding REBOA indications, ideal patient populations, and outcomes is needed in order to improve REBOA perception in trauma surgeons and increase frequency of use.

Abstract
Noncavitary torso hemorrhage is a rare and poorly characterized injury that can lead to exsanguination if not promptly addressed. When present in a high-risk patient on therapeutic anticoagulation, it can lead to a swift fatal outcome. Two cases (an 80-year-old female on warfarin and a 67-year-old male on apixaban for atrial fibrillation) presented with shock after direct blunt trauma in their torsos. Embolotherapy techniques were utilized to obtain angiostasis while the patients were resuscitated with massive transfusion protocols and reversal of the agents received. In the setting of severe localized blunt trauma on an aging victim while on antithrombotic medications, noncavitary torso hemorrhage must be included in the differential diagnosis. Local expertise and a high level of suspicion were critical in the early intervention, and postprocedural management of the injuries sustained and secured a good result.

Abstract
INTRODUCTION Preventable deaths following trauma are high and unchanged over the last two decades. The objective of this study was to describe the location of death in patients with penetrating trauma, stratified by anatomic location of injury, in order to better tailor our approach to reducing preventable deaths from trauma. METHODS This retrospective analysis of a prospectively maintained trauma registry included consecutive adult trauma activations with penetrating trauma at a level 1 trauma center between 07/2012 and 03/2018. Injuries were categorized as extremity, junctional, and torso. Head and neck injuries were excluded. Patients injured in >1 defined location were categorized as "multiple." Location of death was defined as on-scene, emergency department (ED), or hospital. Two-sided χ2 tests were used to compare groups. Multivariate analysis was performed using logistic regression. RESULTS A total of 1024 patients were included with an overall case fatality rate (CFR) of 7.8%. The CFR following extremity injury (3.0%) was significantly lower than all other injury sites (P = .02).There were no significant differences in CFR for junctional (10.4%), torso (8.3%), or multiple injuries (9.6%). Forty percent of fatalities following junctional injury occurred on-scene and an additional 20% occurred in the ED. DISCUSSION To our knowledge, this is the first study to describe location of death stratified by anatomic location of injury. There was no difference in the CFRs of junctional and torso injuries, and a large proportion of deaths occurred prior to reaching the hospital or in the trauma bay. These findings support reevaluating the classical algorithms and care pathways for patients with proximal penetrating trauma.

Abstract
Developments in military personal armour have aimed to achieve a balance between anatomical coverage, protection and mobility. When death is likely to occur within 60 min of injury to anatomical structures without damage control surgery, then these anatomical structures are defined as 'essential'. However, the medical terminology used to describe coverage is challenging to convey in a Systems Requirements Document (SRD) for acquisition of new armour and to ultimately translate to the correct sizing and fitting of personal armour. Many of those with Ministry of Defence responsible for the procurement of personal armour and thereby using SRDs will likely have limited medical knowledge; therefore, the potentially complex medical terminology used to describe the anatomical boundaries must be translated into easily recognisable and measurable external landmarks. We now propose a complementary classification for ballistic protection coverage, termed threshold and objective, based on the feasibility of haemorrhage control within the prehospital environment.

Abstract
Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a technique where a balloon is advanced through the common femoral artery and temporarily inflated for treatment of cardiac arrest or non-compressible haemorrhage. The aim of this study was to measure intravascular distances relevant for correct placement of the REBOA catheter using computer tomographic (CT) scans. In a series of CT scans of the aorta from 100 patients diagnosed with severe aortic stenosis planned for transcatheter aortic valve implantation, we measured the intravascular distance from the insertion site in the common femoral artery to two potential zones for placement of the REBOA catheter; between the left subclavian artery and the celiac trunk (Zone 1), as well as between the aortic bifurcation and the distal take-off of the renal arteries (Zone 3). The mean (± SD) intravascular distance from the femoral artery to intra-aortic Zone 1 was 36 (± 2.5) cm for the lower border and 60 (± 4.1) cm for the upper border, respectively. For intra-aortic Zone 3, the mean (± SD) intravascular distance was 21 (± 2.1) cm to the lower border and 31 (± 2.3) cm to the upper border. Calculated potentially safe intervals for placement of the REBOA in Zone 1 was with 99.7% likelihood between 43 and 48 cm. No similar potentially safe interval could be calculated for Zone 3. According to this cohort study of patients with severe aortic stenosis, the balloon of the REBOA catheter should travel intraarterially between 43 (lower limit) and 48 cm (upper limit) from the site of insertion into the common femoral artery, which would lead to correct placement in intra-aortic Zone 1 in 99.7% of cases. In contrast, no potential safety interval could be similarly defined for insertion in Zone 3.

Abstract
Dodecafluoropentane emulsion (DDFPe) is a novel nanotechnology for oxygen delivery with therapeutic potential for hemorrhagic shock and/or traumatic brain injury (TBI). DDFPe demonstrates efficacy at smaller doses than previously tested perfluorocarbon oxygen therapeutics. This smaller dose potentially eliminates toxicities exhibited by previous oxygen therapeutics, whereas anti-inflammatory properties of DDFPe may alleviate damage from ischemia reperfusion injury. This minireview summarizes our progress in developing a battlefield-ready product to prevent combat death due to hemorrhagic shock and/or TBI. Preclinical studies, for both indications, show promising effects of DDFPe as a resuscitation fluid. DDFPe may become a part of the toolkit for tactical healthcare professionals in battlefield and domestic emergency medicine.

Abstract
In blood, the primary role of red blood cells (RBCs) is to transport oxygen via highly regulated mechanisms involving hemoglobin (Hb). Hb is a tetrameric porphyrin protein comprising of two α- and two β-polypeptide chains, each containing an iron-containing heme group capable of binding one oxygen molecule. In military as well as civilian traumatic exsanguinating hemorrhage, rapid loss of RBCs can lead to suboptimal tissue oxygenation and subsequent morbidity and mortality. In such cases, transfusion of whole blood or RBCs can significantly improve survival. However, blood products including RBCs present issues of limited availability and portability, need for type matching, pathogenic contamination risks, and short shelf-life, causing substantial logistical barriers to their prehospital use in austere battlefield and remote civilian conditions. While robust research is being directed to resolve these issues, parallel research efforts have emerged toward bioengineering of semisynthetic and synthetic surrogates of RBCs, using various cross-linked, polymeric, and encapsulated forms of Hb. These Hb-based oxygen carriers (HBOCs) can potentially provide therapeutic oxygenation when blood or RBCs are not available. Several of these HBOCs have undergone rigorous preclinical and clinical evaluation, but have not yet received clinical approval in the USA for human use. While these designs are being optimized for clinical translations, several new HBOC designs and molecules have been reported in recent years, with unique properties. The current article will provide a comprehensive review of such HBOC designs, including current state-of-the-art and novel molecules in development, along with a critical discussion of successes and challenges in this field.

Abstract
Uncontrolled noncompressible hemorrhage is a major cause of mortality following traumatic injuries in civilian and military populations. An injectable hemostat for point-of-care treatment of noncompressible hemorrhage represents an urgent medical need. Here, we describe an injectable hemostatic agent via polymer peptide interfusion (HAPPI), a hyaluronic acid conjugate with a collagen-binding peptide and a von Willebrand factor-binding peptide. HAPPI exhibited selective binding to activated platelets and promoted their accumulation at the wound site in vitro. In vivo studies in mouse tail vein laceration model demonstrated a reduction of >97% in both bleeding time and blood loss. A 284% improvement in the survival time was observed in the rat inferior vena cava traumatic model. Lyophilized HAPPI could be stably stored at room temperature for several months and reconstituted during therapeutic intervention. HAPPI provides a potentially clinically translatable intravenous hemostat.
