Bleeding complications arising from trauma, surgery, and as congenital, disease-associated, or drug-induced blood disorders can cause significant morbidities and mortalities in civilian and military populations. Therefore, stoppage of bleeding (hemostasis) is of paramount clinical significance in prophylactic, surgical, and emergency scenarios. For externally accessible injuries, a variety of natural and synthetic biomaterials have undergone robust research, leading to hemostatic technologies including glues, bandages, tamponades, tourniquets, dressings, and procoagulant powders...

INTRODUCTION: Optimal teaching and assessment methods and models for emergency airway, breathing and hemorrhage interventions are not currently known. The University of Minnesota Combat Casualty Training consortium (UMN CCTC) was formed to explore the strengths and weaknesses of synthetic training models (STMs) versus Live tissue (LT) models. In this study, we compare the effectiveness of best in class STMs versus an anesthetized caprine (goat) model for training and assessing 7 procedures: Junctional hemorrhage control, Tourniquet (TQ) placement, Chest seal, Needle thoracostomy (NCD), Nasopharyngeal airway (NPA), Tube thoracostomy, and Cricothyrotomy (Cric)...

Importance: Prehospital blood product transfusion in trauma care remains controversial due to poor-quality evidence and cost. Sequential expansion of blood transfusion capability after 2012 to deployed military medical evacuation (MEDEVAC) units enabled a concurrent cohort study to focus on the timing as well as the location of the initial transfusion. Objective: To examine the association of prehospital transfusion and time to initial transfusion with injury survival...

INTRODUCTION: A reproducible, lethal noncompressible torso hemorrhage model is important to civilian and military trauma research. Current large animal models balancing clinical applicability with standardization and internal validity. As such, large animal models of trauma vary widely in the surgical literature, limiting comparisons. Our aim was to create and validate a porcine model of uncontrolled hemorrhage that maximizes reproducibility and standardization. METHODS: Seven Yorkshire-cross swine were anesthetized, instrumented, and splenectomized...

There has been an evolution in the diagnosis and management of vascular trauma over the past 100 years. The primary stimulus to these changes has been the increased volume of patients with cervical, truncal, and peripheral vascular injuries during military conflicts and in civilian life.Patients with "hard" signs of a vascular injury are taken to surgery emergently with a few exceptions to be described. In contrast, patients with "soft" signs of a vascular injury undergo a careful physical examination including measurement of vascular index to determine if radiologic imaging is necessary...

BACKGROUND: Limb tourniquets have been used extensively during modern Middle Eastern conflicts. Despite its undeniable successes, the combat applied tourniquet (C-A-T) has some shortfalls, principally its inability to reliably control lower limb bleeding when applied to the mid-thigh. We tested two tourniquets which may represent an improvement to the combat applied tourniquet; the tactical mechanical tourniquet and the tactical pneumatic tourniquet. METHODS: We recruited 12 healthy service personnel and applied the tactical mechanical tourniquet and tactical pneumatic tourniquet to both lower limbs in a randomly generated sequence...

BACKGROUND: Over the past decade there has been a resurgence of tourniquet use in civilian and military settings. Several key challenges include assessment of limb perfusion and adequacy of tourniquet placement, particularly in the austere or pre-hospital environments. We investigated the utility of thermal imaging to assess adequacy of tourniquet placement. METHODS: The FLIR ONE™ smartphone-based thermal imager was utilized. Ten swine underwent tourniquet placement with no associated hemorrhage (n=5) or with 40% hemorrhage (n=5)...

Hemorrhage is the leading preventable cause of death in civilian and military trauma. Recent data from the ongoing conflicts in Iraq and Afghanistan suggest that early and aggressive tourniquet utilization is a safe and effective way to dramatically reduce mortality from extremity hemorrhage. As a result, prehospital tourniquet use is now endorsed by a majority of professional emergency medicine, emergency medical service and trauma professional societies. However, there currently exists scant evidence supporting the efficacy of commercially available tourniquets in controlling extremity hemorrhage in pediatric trauma patients...

REVIEW
John F Kragh, Michael A Dubick
The purpose of this review is to summarize tourniquet science for possible translation to wilderness settings. Much combat casualty data has been studied since 2005, and use of tourniquets in the military has changed from a last resort to first aid. The US Government has made use of tourniquets a health policy aimed to improve public access to bleeding control items. International authorities believe that education in first aid should be universal, as all can and should learn first aid. The safety record of tourniquet use is mixed, but users are reliably safe if trained well...

REVIEW
Ronald Chang, Brian J Eastridge, John B Holcomb
Hemorrhage is the leading cause of preventable military and civilian trauma death. Damage control resuscitation with concomitant mechanical hemorrhage control has become the preferred in-hospital treatment of hemorrhagic shock. In particular, plasma-based resuscitation with decreased volumes of crystalloids and artificial colloids as part of damage control resuscitation has improved outcomes in the military and civilian sectors. However, translation of these principles and techniques to the prehospital, remote, and austere environments, known as remote damage control resuscitation, is challenging given the resource limitations in these settings...

BACKGROUND: Twenty years ago, the original Tactical Combat Casualty Care (TCCC) article was published in this journal. Since TCCC is essentially a set of bestpractice prehospital trauma care guidelines customized for use on the battlefield, the presence of a journal with a specific focus on military medicine was a profound benefit to the initial presentation of TCCC to the US Military. METHODS: In the two ensuing decades, which included the longest continuous period of armed conflict in our nation's history, TCCC steadily evolved as the prehospital trauma care evidence base was augmented and as feedback from user medics, corpsmen, and pararescuemen was obtained...

REVIEW
Russ S Kotwal, Frank K Butler
During historic, as well as more recent, conflicts, most combat casualties who die from their injuries do so in the prehospital setting. Although many of the injuries incurred by these casualties are nonsurvivable, a number of injuries are still potentially survivable. Of those injuries that are potentially survivable, the majority are truncal, junctional, and extremity hemorrhage. Novel and effective approaches directed toward prehospital hemorrhage control have emerged in recent years, some of which can prove useful in the management of junctional hemorrhage whether in a military or civilian setting...

BACKGROUND: Data regarding the effect of prehospital blood administration to trauma patients during short-to-moderate time evacuations is scarce. The Israel Air Force Airborne Combat Search and Rescue is the only organization that deals with aeromedical evacuation for both military and civilian casualties in Israel and the only one with the ability to give blood in the prehospital setting. METHODS: Data on packed red blood cells (PRBCs) administration in the evacuation missions from January 2003 to June 2010 were analyzed and actual transfusion practice was compared to clinical practice guidelines (CPGs)...

BACKGROUND: The purpose of the present study was to mechanically assess models of emergency tourniquet after 18 months of environmental exposure to weather to better understand risk of component damage. MATERIALS AND METHODS: An experiment was designed to test tourniquet performance on a manikin thigh. Three tourniquet models were assessed: Special Operations Forces Tactical Tourniquet Wide, Ratcheting Medical Tourniquet, and Combat Application Tourniquet. Unexposed tourniquets formed a control group stored in a laboratory; exposed tourniquets were placed outdoors on a metal roof for 18 months in San Antonio, Texas...

In light of the recent terrorist attacks in Europe, we need to reconsider the organization of rescue and medical management and plan for an attack involving multiple pediatric victims. To ensure quick surgical management, but also to minimize risk for on-site teams (direct threats from secondary terrorist attacks targeting deployed emergency services), it is crucial to evacuate patients in a swift but orderly fashion. Children are vulnerable targets in terrorist attacks. Their anatomical and physiological characteristics make it likely that pediatric victims will suffer more brain injuries and require more, often advanced, airway management...

PURPOSE: Wide-awake, local anesthesia, no tourniquet (WALANT) hand surgery was developed to improve access to hand surgery care while optimizing medical resources. Hand surgery in the clinic setting may result in substantial cost savings for the United States Military Health Care System (MHS) and provide a safe alternative to performing similar procedures in the operating room. METHODS: A prospective cohort study was performed on the first 100 consecutive clinic-based WALANT hand surgery procedures performed at a military medical center from January 2014 to September 2015 by a single hand surgeon...

Trauma is a leading cause of death and disability worldwide, in civilian environments and on the battlefield. Trauma-induced haemorrhage is the principal cause of potentially preventable death, which is generally attributable to a combination of vascular injury and coagulopathy. Survival rates following severe traumatic injury have increased due to advanced trauma management initiatives and treatment protocols, influenced by lessons learned from recent conflicts in Iraq and Afghanistan. The use of tourniquets and intraosseous needles, early blood and blood product transfusion, administration of tranexamic acid in pre-hospital settings, and consultant-led damage control resuscitation incorporating damage control surgery have all played their part...
