A Novel Cryotherapy Compression Wrap in the Management of Acute Ankle Sprains: Potential Use for Special Operators on the Battlefield

Boland M, Mulligan I, Payette J, Serres J, O'Hara R, Maupin G 12(4). 17 - 23 (Journal Article)

Objective: Musculoskeletal injuries related to training and operational missions frequently affect military personnel. A common treatment for these injuries is the PRICE (protection, rest, ice, compression, and elevation) method, which is time consuming and impractical in the field. Therefore, the primary objective of this study was to determine the effectiveness of the cryotherapy wrap compared to a traditional treatment in the management of acute ankle sprains. Methods: A randomized controlled clinical trial was conducted in a university research laboratory with 13 subjects (9 males and 4 females) with the following physical characteristics: age (yr) 20.6 ± 2.2, height (cm) 177.0 ± 14.3, weight (kg) 76.6 ± 20.6, and body mass index (kg/m2) 24.1 ± 3.7. Participants were instructed to perform PRICE with a traditional ice pack and compression wrap (control group) or with an Arctic Ease® cryotherapy wrap (test group) for 48 hours following enrollment in the study. The Numeric Pain Scale, Foot and Ankle Ability Measure, and ankle/foot volumetric measurement were performed at initial presentation and 24-hour, 48-hour, and 7-day follow-up intervals. Results: While the comparison of the Numeric Pain Scale scores, Foot and Ankle Ability Measure scores, and volumetric changes between groups revealed no statistically significant differences (ρ > 0.01), there was an 86% compliance rate for subjects in the cryotherapy wrap group compared to a 17% compliance rate of subjects in the control group. Conclusions: The cryotherapy wraps performed comparably to ice therapy and therefore may be especially applicable to military personnel required to operate in austere and hostile environments where traditional therapies are unrealistic. Although this pilot study did not demonstrate that the cryotherapy wraps produce statistically superior results, trends emerged in the data suggesting that subject compliance rate may be improved by using an alternative form of cryotherapy compression, which could lead to better management of pain, edema, and functional recovery. Future research should include a larger sample size to verify this claim.

Atrial Fibrillation with Rapid Ventricular Response following use of Dietary Supplement Containing 1,3 Dimethylamylamine and Caffeine

Armstrong M 12(4). 1 - 4 (Journal Article)

Our nation's servicemembers commonly use dietary supplements to enhance their performance. Despite this prolific use, many of these products have detrimental side-effects that compromise servicemembers' health and could, by proxy, compromise a mission. This paper presents the case of a 32-year old Navy Special Operations Forces (SOF) Sailor who, prior to physical training, used a supplement containing 1,3 Dimethylamylamine (DMAA), and then developed atrial fibrillation with rapid ventricular response. He required intravenous calcium channel blocker administration, followed by beta blockers, for rate control. As military providers, we routinely ask our patients about their use of supplements and while the regulation of these products is beyond the scope of practice for most of us, it is our duty to become better educated about the risks and benefits of these supplements. We must educate our patients and our commands on the potential harm that these supplements may pose.

Case Series of Pectoralis Major Muscle Tears in Joint Special Operations Task Force-Philippines Soldiers Diagnosed by Bedside Ultrasound

Ball V, Maskell K, Pink J 12(4). 5 - 9 (Journal Article)

Pectoralis major muscle tears are an uncommon injury although reported most prevalently among young male athletes (e.g. SOF personnel). We describe two cases occurring in Joint Special Operations Task Force-Philippines (JSOTF-P) Soldiers, review the physical examination and sonographic findings suggestive of a high-grade injury, and discuss treatment options.

Exertional Rhabdomyolysis: Attrition Through Exercise, A Case Series and Review of the Literature

Reese JM, Fisher SD, Robbins DP 12(3). 52 - 56 (Journal Article)

Rhabdomyolysis is a common syndrome that can range from asymptomatic to a severe life-threatening condition. It is the result of acute muscle fiber necrosis leading to cell lysis and subsequent transfer of those byproducts into the circulatory system. The most significant constituent of these byproducts is myoglobin, which has been known to cause renal failure in 10-50% of patients that develop rhabdomyolysis. In addition, the electrolytes contained within these cells are leached into the blood stream, which can lead to significant electrolyte abnormalities. The etiology of rhabdomyolysis is broad and includes inherited diseases, drugs, toxins, muscle compression or overexertion, infections, and more. This syndrome may carry a mortality rate ranging from 7-80%. We describe five patients assigned to various companies within 160th Special Operations Aviation Regiment (Airborne) that developed exertional rhabdomyolysis of the bilateral upper extremities between June 2011 and January 2012. In this case series we will describe the events leading up to the diagnosis, lack of risk factors or family history, diagnostic criteria, treatment, and future concerns related to the condition.

Effect of Hetastarch Bolus in Trauma Patients Requiring Emergency Surgery

Ryan ML, Ogilvie MP, Pereira BM, Gomez-Rodriguez JC, Livingstone AS, Proctor KG 12(3). 57 - 67 (Journal Article)

If blood products are not available, current military guidelines recommend a hetastarch bolus (HEX, Hextend ™ 6% hetastarch in lactated electrolyte buffer, www. for initial treatment of hypovolemic shock in the field. We previously reported that a HEX bolus plus standard of care (SOC = crystalloid plus blood products) was safe during initial resuscitation in 1714 trauma patients. This study tests the hypothesis that HEX+SOC is more effective than SOC alone for volume expansion in trauma patients requiring urgent operation. Methods: From July 2009 to August 2010, the records from all adults who required emergency surgery within 4 hours of admission were screened for a retrospective cohort observational study. Burns, and those with primary neurosurgical or orthopedic indications, were excluded. The study population was comprised of 281 patients with blunt (n = 72) or penetrating (n = 209) trauma; 141 received SOC and 140 received SOC+HEX in the emergency room only (ER, n = 81) or the ER and operating room (OR, n = 59). Each case was reviewed with waiver of consent. Results: After penetrating injury, with SOC, the injury severity score was 17 and mortality was 12%; the corresponding values in the HEX(ER) and HEX(OR) groups were 19-21 and 8%, but these apparent differences did not reach significance. However, in patients receiving HEX, initial heart rate was higher, base deficit was lower, and hematocrit was lower (consistent with relative hypovolemia), even though blood product requirements were reduced, and urine output was greater (all ρ < 0.05). These effects were absent in patients with blunt trauma. Platelet consumption was higher with HEX after either penetrating (ρ = 0.004) or blunt trauma (ρ = 0.045), but coagulation tests were unchanged. Conclusion: HEX is safe for initial resuscitation in young patients who required urgent operation after penetrating trauma, but there was no apparent effect after blunt trauma. A bolus of HEX reduced transfusion requirements without inducing coagulopathy or causing renal dysfunction, but a randomized controlled trial is necessary to eliminate the possibility of selection bias.

Lighting Did Not Affect Self-application of a Stretch and Wrap Style Tourniquet

Wall PL, Welander JD, Sahr SM, Buising CM 12(3). 68 - 73 (Journal Article)

The objective was to determine the effects of darkness on self-application of a stretch and wrap style tourniquet. Methods: Following training and practice, 15 volunteers self-applied the Stretch, Wrap, and Tuck-Tourniquet (SWAT-T) to their leg, thigh, dominant forearm, and dominate arm. Proper application in lighted conditions was followed by the same applications in darkness. Proper stretch was determined by alteration of shapes printed on the tourniquet. Results: High rates of proper application and successful arterial occlusion (60 second Doppler signal elimination) occurred in darkness just as in lighted conditions (darkness: 56 proper and 60 successful of 60 applications, lighted: 57 proper and 53 successful of 60 applications). Lighting did not affect ease of application or discomfort. Males (8) and females (7) were similarly successful. Lower limb applications were predominantly rated easy (51 of 60). Upper limb applications had fewer easy ratings (15 easy, 32 challenging, 13 difficult ratings). Arterial occlusion took < 60 seconds in 112 of 113 successful applications; completion took < 60 seconds in 88 of all 120 applications. Upper limb applications took longer for completion. Conclusions: The SWAT-T stretch and wrap style tourniquet can be self-applied properly even in darkness. When properly applied, it can stop limb arterial flow.

Tactical Physical Preparation: The Case for a Movement-Based Approach

Kechijian D, Rush SC 12(3). 43 - 49 (Journal Article)

Progressive injury prevention and physical preparation programs are needed in military special operations to optimize mission success and Operator quality of life and longevity. While physical risk is inherent in Special Operations, non-traumatic injuries resulting from overuse, poor biomechanics, and arbitrary exercise selection can be alleviated with proper medical care and patient education. An integrated approach to physical readiness that recognizes the continuity between rehabilitation and performance training is advocated to ensure that physiological adaptations do not come at the expense of orthopedic health or movement proficiency. Movement quality should be regularly evaluated and enforced throughout the training process to minimize preventable injuries and avoid undermining previous rehabilitative care. While fitness and proper movement are not substitutes for Operator specific tasks, they are foundational to many tactically-relevant skills. In light of how much is at stake, sports medicine care in the military, especially special operations, should parallel that which is practiced in professional and collegiate athletics.

Gay DG, Paul J 12(3). 50 - 51 (Journal Article)

Special Operations Forces and Incidence of Post-Traumatic Stress Disorder Symptoms

Hing M, Cabrera J, Barstow C, Forsten RD 12(3). 23 - 35 (Journal Article)

To determine the rates of Post-traumatic Stress Disorder (PTSD) positive symptom scores in Special Operations Forces (SOF) personnel, an anonymous survey of SOF was employed, incorporating the PTSD Checklist (PCLM) with both demographic and deployment data. Results indicate that all SOF units studied scored above the accepted cut-offs for PTSD positive screening.1 When total symptom severity score exceeded established cutoff points and were combined with criteria for Diagnostic and Statistical Manual of Mental Disorders, Edition 4 (DSM-IV) diagnosis of PTSD,2 approximately 16-20% of respondents met scoring threshold for positive screening, almost double those of conventional Army units. Collectively, Special Forces (SF) Soldiers and SOF combat- arms Soldiers had significantly higher PLC-M scores than their non-combat-arms SOF counterparts. SOF Soldiers with three or more deployments to Afghanistan had significantly higher PCL-M scores. Considering the evidence suggesting that SOF Soldiers are hyper-resilient to stress, these results should drive further research schemata and challenge clinical assumptions of PTSD within Special Operations.

Unforeseen Risk: Leptospirosis and the U.S. Special Operations Community

Grambusch DM, Hoedebecke KL 12(3). 36 - 42 (Journal Article)

Leptospirosis is a bacterial zoonosis with worldwide distribution and is potentially lethal to those infected if left untreated. Due to the global posture of the U.S. Special Operations community, there is a seemingly perfect overlap of the regions in which they deploy and areas with concurrent endemic leptospirosis infection. Furthermore, Special Operations Forces (SOF) personel are known for working by, with, and through the host nation defense force, who tend to be commonly affected and often serve as a reservoir for this infection. Other risk factors including the usage of infected military working dogs, contaminated training sites, and certain recreational activities associated with water increase the danger of exposure for this cohort. Due to this increased risk of leptospirosis by U.S. Special Operations service members, medical providers within this community must understand and utilize proper preventive medicine, prophylaxis, early detection, diagnosis, and treatment for this potentially lethal infection.

10 Years of SOF Rotary Wing CASEVAC Missions, Training and Equipment: A Retrospective View from the 160th SOAR (A)

Faudree LK 12(3). 14 - 18 (Journal Article)

On 3 October 2001, the first chalk of Night Stalkers left Campbell Army Airfield enroute to Uzbekistan in support of what would become our nation's longest war. The vast majority of Soldiers were untested in war and would quickly have the opportunity to meet with the enemies of our nation in close combat. The two Special Operations Task Forces (TF), TF Dagger to the north in Uzbekistan and TF Sword in the south (aboard the USS Kitty Hawk) were our nation's first strike options against Al Qaeda and Taliban forces in Afghanistan. Due to the inherent nature of forced entry operations (restrictive terrain, lack of medical infrastructure, etc.) TF Dagger and TF Sword utilized 160th Special Operations Aviation Regiment (Airborne) [SOAR (A)] rotary wing aircraft solely for the Casualty Evacuation (CASEVAC) operations during the first months of Operation ENDURING FREEDOM.

Detection of Increased Intracranial Pressure by Ultrasound

Hightower S, Chin EJ, Heiner JD 12(3). 19 - 22 (Journal Article)

Increases in intracranial pressure (ICP) may damage the brain by compression of its structures or restriction of its blood flow, and medical providers my encounter elevated ICP in conventional and non-conventional medical settings. Early identification of elevated ICP is critical to ensuring timely and appropriate management. However, few diagnostic methods are available for detecting increased ICP in an acutely ill patient, which can be performed quickly and noninvasively at the bedside. The optic nerve sheath is a continuation of the dura mater of the central nervous system and can be viewed by ocular ultrasound. Pressure changes within the intracranial cavity affect the diameter of the optic nerve sheath. Data acquired from multiple clinical settings suggest that millimetric increases in the optic nerve sheath diameter detected via ocular ultrasound correlate with increasing levels of ICP. In this review, we discuss the use of ocular ultrasound to evaluate for the presence of elevated ICP via assessment of optic nerve sheath diameter, and describe critical aspects of this valuable diagnostic procedure. Ultrasound is increasingly becoming a medical fixture in the modern battlefield where other diagnostic modalities can be unavailable or impractical to employ. As Special Forces and other austere medical providers become increasingly familiar with ultrasound, ocular ultrasound for the assessment of increased intracranial pressure may help optimize their ability to provide the most effective medical management for their patients.

Omega-3 Fatty Acid Ingestion as a TBI Prophylactic

Barringer N, Conkright W 12(3). 5 - 7 (Journal Article)

Given the hazardous nature of combat operations and training exercises (e.g. airborne operations) conducted by the United States military, servicemembers are at high risk for sustaining a traumatic brain injury (TBI). Since the beginning of the Iraq and Afghanistan wars, almost a quarter of a million servicemembers have sustained a TBI.1 A large number of TBIs are a result of the concussive forces generated by improvised explosive devices (IED). A smaller number are a result of penetrating head wounds. Others may be caused by activities resulting in powerful acceleration, deceleration, or rotational forces. Therapies for treating TBI thus far have been limited. Much of the research conducted to date has focused on post-injury pharmacological interventions.2 Additionally, better protective equipment could help in preventing TBIs; however, these issues are outside the scope of this paper. A relatively new area of research is investigating prophylactic measures taken to lessen the effects of TBI. One such measure involves nutritional interventions and their effects on TBI severity. Therefore, the purpose of this paper is to elucidate the potential benefits of omega-3 fatty acid intake as it relates to TBI severity.

Planning for Success: Desired Characteristics of Special Operations Surgeons, A Pilot Study

Campbell BH, Alderman SM 12(3). 8 - 13 (Journal Article)

Background: Selection criteria for Special Operations Forces (SOF) physicians are often unclear to potential candidates without prior SOF experience. To date, no published career resource exists to guide the careers of physicians interested in becoming a SOF surgeon. Using a survey tool, desirable characteristics and personal attributes were identified that can be used to inform candidate career decisions and better prepare them for a future position in Special Operations. Methods: A descriptive, cross-sectional survey instrument was developed and distributed to current Army SOF Command Surgeons for further distribution to subordinate surgeons. Results were analyzed as a cohort and by subordinate command. Results: Respondents consisted of current SOF Surgeons. Uniformly, the individual characteristics most strongly desired are professionalism, being a team player, and leadership. Possessing or obtaining Airborne and Flight Surgeon qualifications prior to consideration for a surgeon position was highly desired. Residency training within Family Medicine or Emergency Medicine constituted the vast majority of specialty preference. Conclusions: Understanding which characteristics and attributes are desirable to current surgeons and commanders can aid physicians interested in SOF surgeon positions. Using this study and future studies can guide career planning and foster the selection of ideally trained physicians who will operate at the tip of the spear. The views expressed are those of the author(s) and do not reflect the official policy of the Department of the Army, the Department of Defense or the U.S. Government.

A Magnetic Resonance Imaging Study to Define Optimal Needle Length for Humeral Head IO Devices

Rush SC, Bremer J, Foresto C, Rubin AM, Anderson PI 12(2). 77 - 82 (Journal Article)

Introduction: Intraosseous (IO) devices have gained popularity because of TCCC. The ability to gain access to the vascular system when intra venous access is not possible, and techniques such as central lines or cut-downs are beyond the scope of battlefield providers and tactically not feasible, has lead to the increased use of IO access. Since tibias are often not available sites in blast injury patients, the sternum was often used. Recently the humeral head has gained popularity because of ease of access and placement. The optimal needle length has not been defined or studied. Methods and Materials: Fifty consecutive shoulder MRIs among 18-40 year old patients were reviewed. Distances from the skin surface to the cortex from anterior and lateral trajectories were simulated and measured. Two different lateral trajectories were studied described as lateral minimum and lateral maximum trajectories, correlating with seemingly less and greater soft tissue. The cortical thickness was also recorded. Mean values and ranges for the measurements were determined. Results: The anterior trajectory represented the shortest distance. Mean anterior, mean lateral minimum and mean lateral maximum distances were 2.3, 3.0 and 4.7cm with corresponding ranges of 1.1-4.1, 1.6-5.7 and 2.8-7.4cm respectively. The cortical thickness was 4mm in all cases. Conclusions: Although this information was gathered amongst civilians, and many military members may have more soft tissue, these results indicate that needle length generally in the 40-50mm range should be used via the anterior approach. Use of a standard 25mm needle often used in the tibia would be inadequate in over half the cases, and may result in undue tissue compression or distortion.

A Review of Reduction Techniques for Anterior Glenohumeral Joint Dislocations

Dannenbaum J, Krueger CA, Johnson AE 12(2). 83 - 92 (Journal Article)

This review article aims to describe the techniques, success rates, advantages and disadvantages of commonly used anterior shoulder reduction maneuvers. Methods: A review of literature was performed and each article was reviewed for the reported success rates, advantages, disadvantages and technical notes for each anterior shoulder reduction technique. Results: There are a wide variety of very successful shoulder reduction maneuvers, each with their own specific set of advantages and disadvantages. Conclusion: While there are some situations that may favor one of these anterior shoulder reduction techniques over another; it is largely left up to the healthcare provider to determine which maneuver is best on a patient-to-patient basis.

Field Diagnosis and Treatment of Ophthalmic Trauma

Calvano CJ, Enzenauer RW 12(2). 58 - 64 (Journal Article)

Identification and management of injuries to the eyes and ocular adnexa is commonly encountered by frontline medical personnel. This brief review is intended for the Special Forces Medic of all branches and describes the clinical presentation of common ophthalmic and periocular trauma with appropriate management strategies. Prompt recognition of these wounds facilitates early treatment and optimized visual outcomes for affected Soldiers and civilians alike.

Comparison of Airway Control Methods and Ventilation Success With an Automatic Resuscitator

Rodriquez D, Gomaa D, Blakeman T, Petroa M, Dorlac WC, Johannigman J, Branson R 12(2). 65 - 70 (Journal Article)

Mechanical ventilation in an austere environment is difficult owing to logistics, training, and environmental conditions. We evaluated the ability of professional caregivers to provide ventilatory support to a simulated patient using the Simplified Automated Ventilator (SAVe) with a mask hand attended ventilation, mask with single strap unattended ventilation, and supraglottic airway (King LT) ventilation. All three methods were performed using a SAVe with a set tidal volume of 600ml and respiratory rate of 10 breaths per minute. The simulator consisted of a head and upper torso with anatomically correct upper airway structures, trachea, esophagus, and lung which, also measured the delivered tidal volume, respiratory rate, inspiratory flow, and airway pressures. Volunteers used each airway control method to provide ventilation for 10 minutes in random order. Success of each technique was judged as a mean delivered tidal volume of > 500ml. The major finding of this study was that medical professionals using SAVe resuscitator and the manufacturer supplied face mask with single head strap failed to ventilate the airway model in every case.

High Intensity Scenario Training of Military Medical Students to Increase Learning Capacity and Management of Stress Response

Mueller G, Moloff A, Wedmore I, Schoeff J, LaPorta AJ 12(2). 71 - 76 (Journal Article)

A delicate balance exists between a beneficial stress response that enhances memory and recall performance and a detrimental high stress response that impairs memory and learning. Repetitive training in stressful situations enables people to lower their stress levels from the detrimental range to a more beneficial one.1 This is particularly true for physicians in training as they seek to achieve advanced skills and knowledge in the fields of triage, emergency medicine, and surgery prior to graduation. This need is significant for medical students entering military service after graduation. We theorize that military medical students can advance their proficiencies through an Intensive Skills Week (ISW) prior to entering their third and forth year rotations. To test this theory, Rocky Vista University will hold a week long high-intensity first-responder, emergency medicine and surgical training course, facilitated by military medical physicians, to further students' skills and maximize training using the Human Worn Partial Surgical Task Simulator (Cut Suit). We also see the possible benefit to physician and non-physician military personnel, especially Special Operations Forces (SOF) medical personnel, from developing and implementing similar training programs when live tissue or cadaver models are unavailable or not feasible.

PTSD: An Elusive Definition

Kirkbride JF 12(2). 42 - 47 (Journal Article)

The Global War on Terrorism became the longest standing conflict in United States military history on June 7, 2010. It is estimated that 1.64 million U.S. troops have been deployed in support of Operation Enduring Freedom and Operation Iraqi Freedom (ρ xix).1 Both conflicts have produced high numbers of casualties as the result of ground combat. The amount of casualties though has been relatively low compared to other conflicts. Some of this can be attributed to the advances in body armor and emergency medicine that allow many servicemembers to survive conditions that previously led to death. Conversely, surviving these situations leaves those same members with memories that are psychologically difficult to live with and cause chronic difficulties. Unlike an amputee, or the victim of severe burns where the signs and symptoms of their injuries are obvious, patients with psychological disorders can have a range of signs and symptoms common in many other mental disorders, making it difficult to diagnose and treat Soldiers suffering from Post-traumatic Stress Disorder (PTSD).
