The rapid control of traumatic or nontraumatic exsanguinating hemorrhage in critically injured patients is key to limiting morbidity and mortality in civilian and military practice. Resuscitative endovascular balloon occlusion of the aorta (REBOA) has been developed to address potentially preventable death from torso or lower extremity junctional hemorrhage. This time-critical, high-acuity, low-occurrence procedure sometimes precludes the appropriate supervision of clinicians familiar with it. We describe the case of a patient who had recently undergone liver transplantation presenting to the intensive care unit (ICU) and found to be in severe nontraumatic hemorrhagic shock, necessitating REBOA placement as part of the resuscitation. The bedside proceduralist was trained but inexperienced in the procedure and was supervised by a telemedicine intensivist, resulting in rapid and safe insertion. We describe what to our knowledge is the first use of telemedicine to supervise the successful placement of a REBOA catheter in a critically ill patient and discuss how this can potentially benefit military clinicians working in low-resource, far-forward environments.Management of hemorrhagic shock and airway stabilization are two pillars of trauma resuscitation which have a dependent, yet incompletely understood relationship. Patients presenting with traumatic hemorrhage may manifest shock physiology prior to intubation, conferring a higher risk of postintubation hypotension, pulseless arrest, and mortality. This case series describes of a group of seven US military members with combat-related trauma who experienced pulseless arrest after rapid sequence intubation in a role 2 or role 3 setting. All except one of the patients had hemodynamics suggesting hemorrhagic shock prior to intubation. This case series highlights the need for further research to define which trauma patients are at risk of postintubation pulseless arrest. It also focuses on the knowledge gap related to the role that delayed airway management and judicious blood product resuscitation may play in preventable death after injury.Surgical airway approaches are, at times, last resort options in difficult airway management. In Special Operations these interventions confront distorted anatomy from combat trauma, extreme conditions, and may be performed by non-medically trained personnel. Under these circumstances, needle cricothyroidotomy using a large bore intravenous catheter can be considered. A small syringe connected to the needle can confirm transtracheal placement through air aspiration before passing the angiocatheter over the needle. Button activated retracting needles should be avoided for this when possible. We recommend a 3-mL Luer-lock syringe because a small syringe is better suited for generating pressure and once the catheter is in the trachea, this same syringe can be connected to bag valve ventilation by replacing its plunger with a connector from a 6.5-, 7-, or 7.5-mm endotracheal tube. Adding these small and light high-yield items to the Tactical Combat Casualty Care medic inventory should be considered in future revisions.
Limited veterinary care is available in the far forward environment, leading to human medical personnel being responsible, in part, for treatment of military working dogs (MWD). Though guidelines for MWD care exist, there is little research on the care and treatment of MWDs by human medical personnel. There is a lot of research on the care and treatment of MWDs.

This is a secondary analysis of a dataset from the Transportation Command (TRANSCOM) Regulating Command & Control and Evacuation System (TRAC2ES) database within the US Central Command (CENTCOM) from 2008 to 2018. Within this dataset specific to regulated transport from locations within CENTCOM, we abstracted all entries involving MWDs and analyzed causes of injury, type of injury, and interventions performed on traumatically and non-traumatically injured MWDs.

Within our dataset, there were 84 MWD cases for analysis. Of those, 36 (43%) were transported for traumatic injuries, and the remaining 48 (57%) were transported for other medical ailWD data from theater.With a mandate to work by, with, and through host nation partners, Special Operations Forces (SOF) often face the challenge of pursuing humanitarian endeavors in the hopes of securing access to a specific population and mapping the human terrain. Likewise, should limitations in the rules of engagement (ROE) shift incentives from lethal to non-lethal effects, commanders must find unique ways to exert influence on the operational environment. However, with inevitable resource constraints such as money and time, it can be exceedingly difficult to determine which humanitarian project to undertake, especially in a population whose needs are multifaceted. Linear regression, a statistical tool available within the standard Microsoft Excel package on government computers, permits the modeling of predictive outcomes between a number of independent variables against a dependent variable. This allows the determination of significance and effect for each independent variable, which can facilitate a thoughtful recommendation to commanders for project selection. Using Iraq as an example, publicly available information (PAI) provides a wealth of records to make data-driven assessments for mutually beneficial shaping efforts in a stability operations framework. Additionally, this paper will highlight how data can be analyzed without a reliance on statistical software that is unlikely to be present in the tactical environment.Application of maxillomandibular fixation (MMF) for the treatment of jaw fractures has a long history stretching back thousands of years. Modern methods of MMF require extensive training for correct application and are often not practical to perform in a forward operating environment. Most MMF methods carry inherent risks of sharps injuries and exposure to bloodborne pathogens. The authors present a method of MMF with Minnie Ties, which are simple, effective, and much safer than traditional methods of MMF.
Acute compartment syndrome (ACS) following extremity trauma requires rapid fasciotomy to avoid significant morbidity and limb loss. Four-compartment fasciotomy of the leg is a surgical procedure typically performed in the operating room; however, casualties who cannot be rapidly transported may need fasciotomies in the prehospital setting. In the absence of traditional operating instruments (e.g., scalpel, long Metzenbaum scissors, electrocautery), alternative means of fasciotomy may be needed. We undertook a proof-of-concept study using cadaver models to determine whether leg fasciotomies could be performed with alternative devices compared with the surgical standard.

Two-incision, four-compartment fasciotomies were performed on fresh, never-frozen, non-embalmed cadaver legs using a scalpel for the initial skin incision, followed by release of the fascia using one of the following instruments 5.5-in curved Mayo scissors; Benchmade rescue hook (model BM-5BLKW); rescue hook on the Leatherman Raptor multitont such as rescue hooks and the PenBlade. Hook-type devices require longer skin incisions compared with scissors and the PenBlade. In contested environments, patients with ACS may require fasciotomy prior to evacuation to surgical teams; training combat medics in the use of these alternative instruments in the field may preserve life and limb.

Open penetrating trauma wounds to the extremities remain the most common injuries encountered in combat and are frequently complicated by bacterial infections. These infections place a heavy burden on the Servicemember and the healthcare system as they often require multiple additional procedures and can frequently cause substantial debility. Previous studies have shown that vancomycin powder has demonstrated efficacy in decreasing infection risks in clean and contaminated orthopedic surgical wounds.

This review evaluates the most prevalent organisms cultured post-trauma, the current Tactical Combat Casualty Care (TCCC) guidelines for antibiotic prophylaxis, and relevant research of vancomycin's prophylactic use.

Results from previous studies have shown a time-dependent reduction in bacterial load when vancomycin powder is introduced early post injury in traumatic orthopedic wounds. Furthermore, perioperative application affords a cost-effective method to prevent infection with minimal adverse effects.

The current TCCC guidelines advocate for the use of antibiotics at the point of injury. When vancomycin powder is used in synergy with these guidelines, it can contribute a timely and powerful antibiotic to prevent infection.

The prophylactic use of vancomycin powder is a promising adjunctive agent to current Clinical Practice Guidelines (CPG), but it cannot be conclusively determined to be effective without further research into its application in traumatic combat wounds.

An austere field amputation can be a life-saving procedure for an entrapped patient when standard equipment is not available or operable. The objective of this study was to use hand tools to perform cadaveric amputations in < 2 minutes.

Timed guillotine amputation of the extremities on three cadavers was attempted using four available hand tools a multitool, a rescue tool, a hunting knife, and a fixedblade knife. The primary outcome was successful amputation of the extremity in < 2 minutes.

Amputation success was different among the tools. learn more The multitool amputated 78% of attempts; the hunting knife, 67%; the rescue knife, 56%; and the fixed-blade knife, 44%. The distal tibia/fibula and radius/ ulna were amputated successfully in 100% of attempts, whereas none of the tools could amputate the femur. The multitool received the best subjective ranking - 1.4 (p = .001) - by amputators, with the fixed-blade knife receiving the worst score.

In the rare circumstance that an emergent field amputation requires a hand tool, the multitool is a capable instrument for a distal extremity amputation.

We assessed the use of an FDA-cleared transport ventilator with limited functions and settings during ground transport in a swine model of ground evacuation. We hypothesized that when used as an adjunct to extracorporeal life support (ECLS), the device would enable safe mobile ventilatory support during ground evacuation.

Female Yorkshire swine (n = 11; mean, 52.4 ± 1.3 kg) were sedated and anesthetized and received mechanical ventilation (MV) with a standard intensive care unit (ICU) ventilator and were transitioned to the Simplified Automated Ventilator II (SAVe II; AutoMedx) during ground transport. MV served as an adjunct to ECLS in all animals. Ventilator performance was assessed in the uninjured state on day 1 and after bilateral pulmonary contusion on day 2. Data were collected pre- and post-transport on both days.

During 33 transports, the SAVe II provided similar ventilation support as the ICU ventilator. Mean total transport time was 38.8 ± 2.1 minutes. The peak inspiratory pressure (PIP) limit was the only variable to show consistent differences pre- and post-transport and between ventilators.
