Rice-Based Electrolyte Drinks More Effective Than Water in Replacing Sweat Losses During Hot Weather Training and Operations

Gerold KB, Greenough WB, Yasar S 13(4). 12 - 14 (Journal Article)

Heat-related injury presents significant threats to the health and operational effectiveness of Soldiers and military operations. In 2012, active component, U.S. Armed Forces experienced 365 incident cases of heat stroke and 2,257 incident cases of "other heat injury." Most of these occurred among recruit and enlisted personnel and most were under the age of 30. In conditioned military personnel, a rice-based oral rehydration solution was superior to water alone at maintaining body weight and, by inference, enabled Soldiers to better maintain their the state of hydration during prolonged exercise in high ambient temperatures. In view of the health risks associated with dehydration and their effects on training and operations, this study suggests that the consumption of beverages containing electrolytes and a rice-based carbohydrate is superior to the consumption of water alone in preventing dehydration and heat related illness.

Tactical Lighting in Special Operations Medicine: Survey of Current Preferences

Calvano CJ, Enzenauer RW, Eisnor DL, LaPorta AJ 13(4). 15 - 21 (Journal Article)

Success in Special Operations Forces medicine (SOFMED) is dependent on maximizing visual capability without compromising the provider or casualty position when under fire. There is no single ideal light source suitable for varied SOFMED environments. We present the results of an online survey of Special Operations Medical Operators in an attempt to determine strengths and weaknesses of current systems. There was no consensus ideal hue for tactical illumination. Most Operators own three or more lights, and most lights were not night vision compatible. Most importantly, nearly 25% of respondents reported that lighting issues contributed to a poor casualty outcome; conversely, a majority (50 of 74) stated their system helped prevent a poor outcome. Based on the results of this initial survey, we can affirm that the design and choice of lighting is critical to SOFMED success. We are conducting ongoing studies to further define ideal systems for tactical applications including field, aviation, and marine settings.

Drug-Induced Liver Injury Secondary to Testosterone Prohormone Dietary Supplement Use

Hoedebecke KL, Rerucha C, Maxwell K, Butler J 13(4). 1 - 5 (Journal Article)

Dietary supplementation has become progressively more prevalent, with over half of the American population reporting use of various products. An increased incidence of supplement use has been reported in the military especially within Special Operations Forces (SOF) where training regimens rival those of elite athletes. Federal regulations regarding dietary supplements are minimal, allowing for general advertisement to the public without emphasis on the potentially harmful sideeffects. Subsequent medical care for these negative effects causes financial burden on the military in addition to the unit's loss of an Operator and potential mission compromise. This report reviews a case of an Operator diagnosed with drug-induced liver injury secondary to a testosterone prohormone supplement called Post Cycle II™. Clinical situations like this emphasize the necessity that SOF Operators and clinicians be aware of the risks and benefits of these minimally studied substances. Providers should also be aware of the Human Performance Resource Center for Health Information and Natural Medicines Comprehensive Database supplement safety ratings as well as the Food and Drug Administration's MedWatch and Natural Medicines WATCH, to which adverse reactions should be reported.

Identification and Management of Bed Bug Infestations in Austere Environments

Amodt ZT 13(4). 6 - 11 (Journal Article)

Military forces have missions that send them all over the globe. With the reemergence of bed bugs worldwide, the possibility of Servicemembers encountering them has increased. Special Operations Forces are often sent to locations that may not have integrated pest management support. Knowing how to identify and manage a bed bug infestation, with and without proper equipment and supplies, may become necessary in the very near future. It is also important that Servicemembers are aware of how bed bugs travel, to prevent their dispersal back to the United States and into their barracks and homes.

Operator Training and TEMS Support: A Survey of Unit Leaders in Northern and Central California

Young JB, Galante JM, Sena MJ 13(3). 92 - 97 (Journal Article)

Background: Members of Special Weapons and Tactics (SWAT) teams routinely work in high-risk tactical situations. Awareness of the benefit of Tactical Emergency Medical Support (TEMS) is increasing but not uniformly emphasized. Objectives: To characterize the current regional state of tactical medicine and identify potential barriers to more widespread implementation. Methods: A multiple-choice survey was administered to SWAT team leaders of 22 regional agencies in northern and central California. Questions focused on individual officer self-aid and buddy care training, the use and content of individual first aid kits (IFAKs), and the operational inclusion of a dedicated TEMS provider. Results: Respondents included city police (54%), local county sheriff (36%), state law enforcement (5%), and federal law enforcement (5%). Results showed that 100% of respondents thought it was "Very Important" for SWAT officers to understand the basics of self-aid and buddy care and to carry an IFAK, while only 71% of respondents indicated that team members actually carried an IFAK. In addition, 67% indicated that tourniquets were part of the IFAK, and 91% of surveyed team leaders thought it was "Very Important" for teams to have a trained medic available onsite at callouts or high-risk warrant searches. Also, 59% of teams used an organic TEMS element. Conclusion: The majority of SWAT team leaders recognize the benefit of basic Operator medical training and the importance of a TEMS program. Despite near 100% endorsement by unit-level leadership, a significant proportion of teams are lacking one of the key components including Operator IFAKs and/or tourniquets. Tactical team leaders, administrators, and providers should continue to promote adequate Operator training and equipment as well as formal TEMS support

Rabies

Burnett MW 13(3). 102 - 104 (Journal Article)

Rabies has been a scourge of mankind since antiquity. The name itself, "rabies" is derived from the ancient Sanskrit rabhas meaning "to do violence" and has been found described in medical writings several thousand years old. The rabies virus is an RNA virus of the family Rhabdoviridae (Greek for "rod-shaped virus"), genus Lyssavirus (Lyssa being the Greek God of frenzy and rage). Rabies infections have a worldwide spread, with only a few, mostly island nations laying claim to being "rabies free."

Management of Open Pneumothorax in Tactical Combat Casualty Care: TCCC Guidelines Change 13-02

Butler FK, Dubose JJ, Otten EJ, Bennett DR, Gerhardt RT, Kheirabadi BS, Gross K, Cap AP, Littlejohn LF, Edgar EP, Shackelford S, Blackbourne LH, Kotwal RS, Holcomb JB, Bailey JA 13(3). 81 - 86 (Journal Article)

During the recent United States Central Command (USCENTCOM) and Joint Trauma System (JTS) assessment of prehospital trauma care in Afghanistan, the deployed director of the Joint Theater Trauma System (JTTS), CAPT Donald R. Bennett, questioned why TCCC recommends treating a nonlethal injury (open pneumothorax) with an intervention (a nonvented chest seal) that could produce a lethal condition (tension pneumothorax). New research from the U.S. Army Institute of Surgical Research (USAISR) has found that, in a model of open pneumothorax treated with a chest seal in which increments of air were added to the pleural space to simulate an air leak from an injured lung, use of a vented chest seal prevented the subsequent development of a tension pneumothorax, whereas use of a nonvented chest seal did not. The updated TCCC Guideline for the battlefield management of open pneumothorax is: "All open and/ or sucking chest wounds should be treated by immediately applying a vented chest seal to cover the defect. If a vented chest seal is not available, use a non-vented chest seal. Monitor the casualty for the potential development of a subsequent tension pneumothorax. If the casualty develops increasing hypoxia, respiratory distress, or hypotension and a tension pneumothorax is suspected, treat by burping or removing the dressing or by needle decompression." This recommendation was approved by the required two-thirds majority of the Committee on TCCC in June 2013.

The Agitated Patient

Goldstein S 13(3). 87 - 91 (Journal Article)

Caring for an agitated patient can be a daunting task for the tactical emergency medical support (TEMS) or Special Operations Forces (SOF) medic. The cause, degree, and duration of agitation can vary among such individuals. These patients create a high-stress and disruptive environment, needing numerous people involved to control. One agitated patient can disrupt an entire tactical team or casualty evacuation. The patient's history and physical examination can give important clues to the cause, thereby directing treatment and leading to a quick and safe resolution. The variety of treatments for the agitated patient are just as numerous as the causes and range from verbal deescalation to medications and physical restraint, all of which have a risk-benefit profile to consider.

Cultural Competency and Patient-Centered Communication: A Study of an Isolated Outbreak of Urinary Tract Infections in Afghanistan

Culbertson NT, Scholl BJ 13(3). 70 - 73 (Journal Article)

Background: Personal hygiene is strongly associated with disease prevention and is especially important during prolonged patrol or combat operations. Understanding cultural variances associated with personal hygiene is critical for Special Operation Forces (SOF) medics to prevent, monitor, and treat acquired and transmitted infections while working with host nation personnel. Case Presentation: During a multiday, long-range patrol, approximately 40 male Afghan National Army troops between the ages of 22 and 49 presented for treatment of burning or pain while urinating. All patients were empirically diagnosed with urinary tract infections. Methods and Discussion: The high attack rate and isolated nature of the outbreak suggested that personal hygiene or sexual intercourse was the most likely cause of the isolated outbreak. However, the cultural sensitivity of both topics made social history gathering a difficult task. After participating in a detailed medical interview, one patient revealed that he and his comrades were blocking their urethras with clay plugs after voiding to prevent residual urine from dripping onto their clothes. Conclusions: This case study presents what might be an undocumented practice carried throughout many ethnic cultures endogenous to Afghanistan and discusses how cultural barriers can impact effective health care delivery.

Preparing for Operations in a Resource-Depleted and/or Extended Evacuation Environment

Corey G, Lafayette T 13(3). 74 - 80 (Journal Article)

The wars in Afghanistan and Iraq are the only conflicts to which many medics have ever been exposed. These mature theaters have robust medical systems that ensure rapid access to full-spectrum medical care for all combat-wounded and medically injured personnel. As current conflicts draw to a close, U.S. medics may be deployed to environments that will require the ability to stabilize casualties for longer than 1 hour. Historical mission analysis reveals the need to review skills that have not been emphasized during upgrade and predeployment training. This unit's preparation for the extended care environment can be accomplished using a 4-point approach: (1) review of specific long-term skills training, (2) an extended care lab that reviews extended care skills and then lets the medic practice in a real-time scenario, (3) introduction to the HITMAN mnemonic tool, which helps identify and address patient needs, and (4) teleconsultation.

Traumatic Brain Injury: Analysis of Functional Deficits and Posthospital Rehabilitation Outcomes

Lewis FD, Horn GJ 13(3). 56 - 61 (Journal Article)

Background: Advances in emergency medicine, both in the field and in trauma centers, have dramatically increased survival rates of persons sustaining traumatic brain injury (TBI). However, these advances have come with the realization that many survivors are living with significant residual deficits in multiple areas of functioning, which make the resumption of a quality lifestyle extremely difficult. To this point, TBI has recently been characterized as a chronic disease. As with other chronic diseases, TBI is often causative of persistent disabling symptoms in multiple organ systems. Therefore, posthospital residential rehabilitation programs have emerged to treat these symptoms with the goal of helping these individuals regain function and live more productive and independent lives. Purpose: This study examined the nature and severity of residual deficits experienced by a group of 285 brain-injured individuals and evaluate the efficacy of posthospital residential rehabilitation programs in treating those deficits. Method: Participants consisted of 285 individuals who had sustained a TBI and, due to multiple residual deficits, were unable to care for themselves, necessitating admission to residential posthospital rehabilitation programs. All participants were evaluated at admission and discharge on the Mayo-Portland Adaptability Inventory-Version 4 (MPAI-4). The MPAI-4, developed specifically for persons with acquired brain injury, measures 29 areas of function often affected by TBI. Results: From the 29 skills evaluated, the 12 most often rated as causing the greatest interference with function were identified. Of these skills, the cognitive deficits including memory, attention/concentration, novel problem solving, and awareness of deficits were highly correlated with disruption in performing everyday societal roles. The impact of treatment for reducing the level of disability in these areas was statistically significant, t(284) = 17.43, p < .0001. Improvement was significant even for participants admitted more than 1 year postinjury, t(78) = 8.05, p < .0001. Conclusions: Skill deficits interfering with reintegration into home and community are highly interrelated and should be treated with the understanding that progress in one area may be dependent on change in another area. Cognitive skills including memory, attention/ concentration, novel problem solving, and awareness of deficits were highly correlated with measures of overall functional outcome. Posthospital programs using a multidisciplinary treatment approach achieved significant reduction in disability from program admission to discharge. The benefits of these programs were realized even for the most chronically-impaired participants.

Cultural Self-Awareness as a Crucial Component of Military Cross-Cultural Competence

Pappamihiel CJ 13(3). 62 - 69 (Journal Article)

The military forces in the United States represent a unique culture that includes many subcultures within their own military society. Acculturation into the military often deemphasizes the influence of personal narrative and thereby establishes the primacy of military culture over personal cultural influences. The authors make the argument that military personnel need to further develop an understanding and appreciation of personal cultural narrative as well as organizational culture. The increased integration of military personnel with interagency partners, along with cooperative efforts between relief organizations, and nongovernmental organizations in politically/economically unstable areas around the globe serves to make cross-cultural interaction unavoidable in the future. Military medical personnel are especially likely to interact with others who have culturally different values. These interactions can occur between organizations as easily as they can during patient care. They must be able to step outside of their military culture and develop cross-cultural competence that is grounded in cultural self-awareness. Without an appropriate level of cultural self-awareness, military and medical personnel run the risk of being unable to communicate across dissimilar cultures or worse, alienating key stakeholders in collaborative operations between military services, coalition partners, and nonmilitary organizations. It is the authors' contention that unless military personnel, especially those in the medical arena, are able to appropriately self-assess situations that are impacted by culture, both their own and the other personnel involved, the resulting cultural dissonance is more likely to derail any significant positive effect of such collaborations.

Blast Traumatic Brain Injury - What Do We Know?

Rolan T 13(3). 45 - 50 (Journal Article)

Traumatic brain injury (TBI) is a significant problem in both the civilian and military worlds. Although much is understood about the effects of TBI, relatively few diagnostic or therapeutic modalities are available. Currently, TBI treatment is in a primitive phase and other than acute lifesaving interventions, is largely relegated to rehabilitation efforts. This article discusses known aspects of neuronal injury related to blast TBI, as well as a review of the current state of diagnostic and therapeutic interventions.

Deployed Assessment and Management of mTBI Casualties

Garfin B 13(3). 51 - 55 (Journal Article)

The wars in Afghanistan and Iraq have placed a spotlight on screening, evaluation, and treatment of mild traumatic brain injury, otherwise known as concussion. The author presents a mass casualty case in which a Ranger company medical section assessed and managed 30 Servicemembers (SM) diagnosed with concussion. Through the process of treating these Servicemembers, a consolidated checklist was created based on existing Department of Defense, United States Special Operations Command (USSOCOM), and United States Army Special Operations Command (USASOC) guidelines. During this and subsequent clinical encounters, utilization of this checklist resulted in efficient identification of concussed personnel, appropriate treatment, and documentation.

MEDEVAC Use of Ketamine for Postintubation Transport

Grumbo R, Hoedebecke KL, Berry-Caban CS, Mazur A 13(3). 36 - 41 (Journal Article)

The use of traditional sedatives and analgesics in intubated patients can have undesired hemodynamic consequences with increases in sedation exacerbating hypotension and potentially avoidable morbidity and mortality. This project compared 50 intubated patients using traditional analgesics and sedatives to 20 intubated patients using ketamine with the hypothesis that there would be a significant difference in subsequent blood pressure drop between the two groups. Though the results did not prove to be statistically significant within this small study, the authors did observe a trend toward significance. Additionally, some hypotensive patients had traditional analgesics and sedatives withheld altogether, which did not occur within the ketamine group. Due to the reduced side-effect profile, deployed medical providers should have increased training with and use of ketamine in the pre-hospital setting.

Digital Intubation: The Two-Fingered Solution to Securing an Airway

Cashwell MJ, Wilcoxen AC, Meghoo CA 13(3). 42 - 44 (Journal Article)

Digital intubation is a useful technique that is rarely taught in conventional airway management courses. With limited equipment and minimal training, a Special Operations Forces (SOF) medic can use this technique to intubate an unconscious patient with a high degree of success. The objectives of this report are to (1) learn the sequence of events for successful digital intubation, (2) recognize and appreciate the advantages and limitations of this technique, and (3) appreciate the requirements for establishing a unit-level training program.

Rigid Eye Shields: A Critical Gap in the Individual First Aid Kit

Brunstetter T, Diaz GY, Wasner C, Hart S, Burrows S 13(3). 26 - 28 (Journal Article)

From 5% to 22% of all U.S. Department of Defense combat casualties between 2001 and 2010 suffered some form of ocular trauma. Ocular injuries have an inordinately dramatic impact on return to duty, retention, and reintegration; only 25% of warfighters with severe ocular trauma return to duty. After a traumatic ocular event, the likelihood of saving an eye and preserving vision depends on several factors, especially the treatment quality at the point of injury. Every major organization associated with combat casualty care (e.g., the U.S. Army Institute of Surgical Research, the Committee on Tactical Combat Casualty Care, and the Department of Defense/VA Vision Center of Excellence) emphasizes the importance of placing a rigid eye shield on known/suspected eye injuries at point of injury. On the battlefield, there is no better way to protect an injured eye from further damage than with an eye shield, but shields are not readily available in individual first aid kits. Therefore, it is highly recommended that each Service rapidly integrate at least one rigid eye shield into every individual first aid kit, making them immediately available to every warfighter.

Design and Demonstration of a Battery-Less Fluid Warmer for Combat

Ndao S, Jensen KF, Velmahos GC, King DR 13(3). 31 - 36 (Journal Article)

Background: Prehospital battlefield hypothermia remains an issue, with cold fluid resuscitation likely being a significant contributor. Currently, no prehospital battlefield technology exists to warm intravenous resuscitation fluids. Existing commercial fluid-warming technologies are either inadequate or unreliable or have an unacceptable weight and size, making them inappropriate for the austere combat environment. We propose the creation of a battery-less, flameless, portable, low- weight, small, chemically powered fluid warmer for the battlefield. Methods: A magnesium-based exothermic chemical reaction was used as the sole heating source. A low-weight, small insulated container was created to contain the reaction. The chemical reaction was manipulated to sustain fluid heating as long as required. Results: The exothermic reaction was used to boil a Fluorinert ™ liquid within an insulated container that heats resuscitation fluid passing through the heat exchanger. A working prototype device, 9 inches in length and 4 inches in diameter, was engineered and tested. Warming was maintained over a variety of clinically relevant flow rates. Conclusion: A chemically based, safe, battery-less, flameless, lightweight fluid warmer was created. This technology could represent a significant remote capability currently unavailable on the battlefield.
