Use of Loco-regional Anesthesia in Austere Environments: A Review by and for Special Forces Medics.

Special Forces increasingly operate in austere environments, which are known to have limited medical support and prolonged evacuation times. On the battlefield, pain remains the first complaint of casualties and can impact direct autonomic stability, recovery, and the development of posttraumatic stress disorder. Although medical education has been improving, medical providers still encounter difficulties, such as lack of human and material resources, while trying to achieve pain management. This article summarizes a survey sent to 35 Special Operations medical providers and suggests possible strategies to address challenges to pain management on the battlefield. Potential solutions have been gathered through medical texts, medical/NATO documents, and medical expertise. Nerves blocks have been identified as valuable tools for pain management in the current battlefield environment, where prolonged evacuation and limited freedom of movement are the norm. The survey showed that, although the vast majority of providers had already received lectures on regional anesthesia, 83% were not trained in it, and 54% had never been made aware of multimodal analgesia. This lack of familiarity highlights knowledge and training gaps in nerve block techniques. Diffusion blocks are a very low-risk, useful, and safe pain management technique, which requires less skill sustainment and resources than more complex techniques. The use of epinephrine as adjunct can be useful for decreasing local anesthetic toxicity and increasing long-term pain management. The need for both education on and training in the use of nerve blocks has been identified by the Special Operations health provider community.

Special Operations and Space Medicine for a Joint Future.

This paper is designed to introduce, propose, inform, and advocate enhanced relationships between the medical communities of special operations and space. Although each provides service support in different roles and functions, similarities in both the operational context and in medical care are notable. During a recent interaction, significant relationship potential was discovered by both communities, and recommendations for greater engagement are proposed herein. By identifying and appreciating similarities and understanding history, key actors, and authorities to analyze and realize opportunities will enable us to find synergy for the development of like efforts and goals. Collaboration in research on the limits of human performance and medical support to the most austere and challenging operational environments may benefit both communities in different but productive ways. Establishing and increasing cooperation will also meet command strategic intent, explore and advance a policy concept, initiate a relationship between unique medical communities, and provide a tangible success for the advancement of operational support.

Proficiency in Improvised Tourniquets for Extremities: A Review.

Tourniquets have become ubiquitous tools for controlling hemorrhage in the modern prehospital environment, and while commercial products are preferable, improvised tourniquets play an important role when commercial options are not available. A properly constructed improvised tourniquet can be highly effective provided the user adheres to certain principles. This review article identifies key skills in the construction and application of improvised tourniquets on an extremity. An improvised tourniquet design for an extremity should include three components: a strap, a rod, and a securing mechanism. The strap can be made from a variety of materials, but cravat- like fabric has been shown to work well. Optimal strap dimensions should be at least 2cm in width and a continuous segment long enough to extend around the extremity while still offering ends to accommodate and secure the rod. The rod should be constructed from a material that is hard, strong, and capable of withstanding the torque placed on it without bending or breaking. After torque is applied, the rod must be secured into position to maintain the constricting force and survive patient transport. Finally, the need for an improvised tourniquet is a contingency that all first responders should anticipate. Hands-on training should be conducted routinely in conjunction with other first responder tasks.

A Case for Improvised Medical Training.

The hyperresourced, uber-controlled, ultrareactive, constant environment that we have come to know in the past 20 years should not be mistaken as the norm in conflict. In truth, unrealistic expectations of both commanders and systems in resourcing is presently being reinforced almost daily. Only in the past few years of this decade have the majority of allied forces experienced challenge in resupply and support in contingency operations. When logistical lines are cut, limited, or untimely, we must know and exercise other means of providing the highest level of medical care possible-if not with indigenous ways and means, then by improvisation. History has proved that improvised medicine can be capable, professional, and ethically sound if practiced properly and to standards, the price being time, education, and investment in the requirement. Most often, these are already time-honored means of care.

Use of a Tuning Fork for Fracture Evaluation: An Introduction for Education and Exposure.

Radiographs, bones scans, and even ultrasound may be rare in the austere or acute environment for the evaluation of suspected musculoskeletal fractures. Having an easy, simple, and confident means of objective evaluation used in conjunction with the patient presentation, history, and physical findings may provide a more efficient and economical means of treatment. This introduction and review of selected literature are meant to provide a fuller understanding and consideration for the methods of using a tuning fork in fracture assessment.

Maggot Therapy for Wound Care in Austere Environments.

The past 25 years have seen an increase in use of maggot therapy for wound care. Maggot therapy is very effective in wound debridement; it is simple to apply and requires very little in the way of resources, costs, or skilled personnel. These characteristics make it well suited for use in austere environments. The use of medical-grade maggots makes maggot therapy nearly risk free, but medical grade maggots may not always be available, especially in the wilderness or in resource-limited communities. By understanding myiasis and fly biology, it should be possible even for the nonentomologist to obtain maggots from the wild and apply them therapeutically, with minimal risks.

Damage control and point of injury care: extending the care continuum to military prehospital providers.

Damage control principles are well founded, well proven, and have been incorporated into many specialties of clinical care in both military and civilian practice. Theories regarding hemostatic and hypovolemic resuscitation and preventing the Lethal Triad have had profound effects on the survival of wounded during the present conflicts. As we continue to refine these practices, implementation of this theory should be extended to military prehospital providers. The impacts of damage control practices from those providing initial treatment could complete the continuity of care, prime patients for additional success, and affect overall morbidity and mortality. The basic tenets of damage control theory are easily transferred to the Role I provider in the field and may even address their unique requirements more appropriately. Understanding the working concept of damage control would improve decision-making skills in both therapeutics and evacuation while managing casualties in the uncontrolled environment of combat. Military prehospital damage control differs greatly from in-hospital use, in that the principles must incorporate both medical and tactical considerations for care of the wounded. Introducing damage control principles to established casualty care guidelines will recognize and unite an often underappreciated level of care into a successful practice.

Damage control resuscitation for the Special Forces medic: simplifying and improving prolonged trauma care: Part One.

Current operational theaters have developed to where medical evacuation and surgical assets are accessible in times comparable to the United States. While this has been an essential tool in achieving the best survivability on a battlefield in our history, the by-product of this experience is a recognized shortcoming in current protocols and capabilities of Special Forces medics for prolonged care. The purpose of this article is to provide a theory of care, identify training and support requirements, and to capitalize on current successful resuscitation theories in developing a more efficient and realistic capability under the worst conditions.

Damage control resuscitation for the Special Forces medic--simplifying and improving prolonged trauma care--part two.

Present and future Special Forces missions will require prolonged care of the trauma patient. The Special Forces Medic and Independent Duty Corpsman must be prepared to deal with these situations in the most challenging and austere environments. The implementation of damage control resuscitation for prolonged trauma care can maximize results with minimal support while preventing death, priming the patient for surgical success, and expediting recovery. Establishing this model of care and equipping medics with the essential equipment will have a lasting effect on the survival rate of our casualties, and negate the enemy's political victories when American and allied lives are lost.
