Battlefield medicine

INTRODUCTION: Women comprise nearly 19% of the U.S. military and now serve in almost all operational roles, increasing their risk of combat trauma and injuries.3 Data from the Joint Trauma Registry during Operation Enduring Freedom shows that battle-injured females had a higher case fatality rate at 36% compared to their male counterparts at 17%.1 The Tactical Combat Casualty Care curriculum is used to prepare battlefield medics to provide immediate care to wounded service members, but fails to address differences in the care of female versus male casualties...

Battlefield injuries result in acute and severe uncontrolled pain, which can be reduced with the early use of analgesia. Apart from pain, battlefield injuries may also cause significant morbidity and a prolonged period of absence from active duty. Traditionally available opioids are known to cause various undesirable side effects such as respiratory depression that may worsen the condition of an already injured combatant. Nalbuphine is an opioid agonist-antagonist and has been increasingly used for postoperative analgesia over the last decade...

INTRODUCTION: Point of use (POU) treatment is a critical first step of medical device reprocessing. Reusable instruments and flexible endoscopes require a minimum of terminal sterilization or high-level disinfection, neither of which can be guaranteed if POU is performed incorrectly. Compliance considerations for POU include hospital accreditation readiness, unique austere surgical mission requirements, and the transition of future conflict towards Large Scale Combat Operations. This integrative review aims to describe POU for reusable instruments and endoscopes, and extrapolate implications for Military Health System policies and future considerations...

The Russian invasion of Ukraine in 2022 caused a significant spike in the number of deaths from blast injury. The impossibility of evacuating the bodies of dead servicemen or civilians from the battlefield for a long time leads to the fact that forensic experts often have to deal with the examination of bodies in a state of decomposed changes. At the same time, the material and technical support of forensic medical institutions in different parts of Ukraine is heterogeneous: most experts do not have access to laboratory or instrumental research methods and can only rely on macroscopic research data...

INTRODUCTION: If left untreated, burn injuries can deepen or progress in depth within the first 72 hours after injury as a result of increased wound inflammation, subsequently worsening healing outcomes. This can be especially detrimental to warfighters who are constrained to resource-limited environments with delayed evacuation times to higher roles of care and more effective treatment. Preventing this burn progression at the point of injury has the potential to improve healing outcomes but requires a field-deployable therapy and delivery system...

BACKGROUND: The war in Ukraine urged a need for prompt deliv- erance and resupply of tourniquets to the front. Producing tour- niquets near the battlefront was a feasible option with respect to resupply and cost. METHODS: A locally produced 3D-printed tourniquet (Ukrainian model) from the "Tech Against Tanks" charity was tested against commercially available and Committee of Tactical Combat Casualty Care (CoTCCC)- recommended tourniquets (C-A-T™ and SOF™TT-W)...

BACKGROUND: The Committee on En Route Combat Casualty Care recently ranked the patient handoff as their fourth research priority. Bluetooth technology has been introduced to the battlefield and has the potential to improve the tactical patient handoff. The purpose of this study is to compare the traditional methods of communication used in tactical medical evacuation by Special Operations medical personnel (radio push-to-talk [PTT] and Tactical Medic Intercom System [TM-ICS]) to Bluetooth communication...

In 2020, the U.S. Department of Defense officially disclosed a set of ethical principles to guide the use of Artificial Intelligence (AI) technologies on future battlefields. Despite stark differences, there are core similarities between the military and medical service. Warriors on battlefields often face life-altering circumstances that require quick decision-making. Medical providers experience similar challenges in a rapidly changing healthcare environment, such as in the emergency department or during surgery treating a life-threatening condition...

The complement is a crucial immune defense system that triggers rapid immune responses and offers efficient protection against foreign invaders and unwanted host elements, acting as a sentinel. Activation of the complement system occurs upon the recognition of pathogenic microorganisms or altered self-cells by pattern-recognition molecules (PRMs) such as C1q, collectins, ficolins, and pentraxins. Recent accumulating evidence shows that pentraxins establish a cooperative network with different classes of effector PRMs, resulting in synergistic effects in complement activation...

INTRODUCTION: A Clinical Decision Support System that provides just-in-time medical guidance at the point of injury is being developed. To develop a user interface, a user-centered design approach was taken. MATERIALS AND METHODS: To evaluate the system, personas of the users were created, a comparative analysis of the system against the Tactical Combat Casualty Care Card and Battlefield Assisted Trauma Distributed Observation Kit was completed, and user testing was performed...

INTRODUCTION: Battlefield-related wound infections are a significant source of morbidity among combat casualties. Seasonality of these infections was demonstrated in previous conflicts (e.g., Korea) but has not been described with trauma-related health care-associated infections from the war in Afghanistan. METHODS: The study population included military personnel wounded in Afghanistan (2009-2014) medevac'd to Landstuhl Regional Medical Center and transitioned to participating military hospitals in the United States with clinical suspicion of wound infections and wound cultures collected ≤7 days post-injury...

INTRODUCTION: The insufficiency of current methods to capture the context and environment of neurocritical care can negatively impact patient outcomes. Insertion of an external ventricular drain (EVD) into the ventricles to monitor intracranial pressure (ICP) is a common lifesaving procedure for acquired brain injury patients. Yet, nursing interventions that significantly affect the measured ICP value, such as changing the EVD stopcock position, are poorly documented. Environmental factors like light and noise levels are not monitored as standard of care despite worse outcomes in patients affiliated with sensory sensitivities...

INTRODUCTION: Remote military operations require rapid response times for effective relief and critical care. Yet, the military theater is under austere conditions, so communication links are unreliable and subject to physical and virtual attacks and degradation at unpredictable times. Immediate medical care at these austere locations requires semi-autonomous teleoperated systems, which enable the completion of medical procedures even under interrupted networks while isolating the medics from the dangers of the battlefield...

INTRODUCTION: Hemorrhage is responsible for 91% of preventable prehospital deaths in combat. Bleeding from anatomic junctions such as the groin, neck, and axillae make up 19% of these deaths, and reports estimate that effective control of junctional hemorrhage could have prevented 5% of fatalities in Afghanistan. Hemostatic dressings are effective but are time-consuming to apply and are limited when proper packing and manual pressure are not feasible, such as during care under fire. CounterFlow-Gauze is a hemostatic dressing that is effective without compression and delivers thrombin and tranexamic acid into wounds...

INTRODUCTION: Future combat environments will be complex, making effective care for multi-domain battlefield injuries more challenging. Technology and resources are essential to reduce provider burden enabling more accurate assessments, decision-making support, expanded treatment, and outcome improvements. Experimentation exercises to evaluate concepts and technologies to incorporate into the Army's future force ensure rapid and continuous integration across air, land, sea, space, and cyberspace domains to overmatch adversaries...

INTRODUCTION: Apps that support telemedicine on the battlefield typically run on classified devices and transmit information over classified networks, whereas the medical data the apps create and transmit are unclassified. Current systems treat these data as classified, so a cross-domain solution is required to transfer the data back to an unclassified domain, which adds delays and costs to the process of transmitting critical data needed to treat injured warfighters. To address this gap, ATC-NY developed DroidChamber, which is a software-based Android system that enables multilevel security and which runs on smartphones and tablets...

INTRODUCTION: Clinical documentation is an essential component of the provision of medical care, enabling continuity of information across provider and site handoffs. This is particularly important in the combat casualty care setting when a single casualty may be treated by four or more or five completely disparate teams across the roles of care. The Battlefield Assisted Trauma Distributed Observation Kit (BATDOK) is a digital battlefield clinical documentation system developed by the Air Force Research Laboratory to address this need...

INTRODUCTION: The U.S. Military's Golden Hour policy led to improved warfighter survivability during the Global War on Terror. The policy's success is well-documented, but a categorical evaluation and stratification of medical evacuation (MEDEVAC) times based on combat injury is lacking. METHODS: We queried the Department of Defense Joint Trauma System Prehospital Trauma Registry for casualties with documented penetrating neck trauma in Afghanistan requiring battlefield MEDEVAC from June 15, 2009, through February 1, 2021...

BACKGROUND: Hemorrhage has always been the focus of battlefield and pre-hospitalization treatment. With the increasing fatality rates associated with junctional bleeding, treatment of bleeding at junctional sites has gradually gained attention in battlefield trauma emergency care. We designed a modified chain-based sponge dressing with a medical polyvinyl alcohol sponge that can be used to treat junctional hemorrhage and tested its hemostatic efficacy and biocompatibility. METHODS: Twenty adult Bama miniature pigs were randomly divided into the modified chain-based sponge dressing (MCSD) and standard gauze (SG) groups...
