Some focus on special circumstances such as avalanches while others have a broader scope such as trauma care. Several core areas of key interest within wilderness medicine are discussed in this study. RESULTS: Wilderness medicine is characterized by remote and improvised care of patients with routine or exotic illnesses or trauma, limited resources and manpower, and delayed evacuation to definitive care.
Wilderness medicine is developing rapidly and draws from the breadth of medical and surgical subspecialties as well as the technical fields of mountaineering, climbing, and diving. Research, epidemiology, and evidence-based guidelines are evolving. A hallmark of this field is injury prevention and risk mitigation. The range of topics encompasses high-altitude cerebral edema, decompression sickness, snake envenomation, lightning injury, extremity trauma, and gastroenteritis.
Several professional societies, academic fellowships, and training organizations offer education and resources for laypeople and health care professionals. Although wilderness medicine research is technically difficult to perform, it is essential to deepening our understanding of the contribution of specific techniques in achieving improvements in clinical outcomes.
Backer, MD, a pastpresident of the Wilderness Medical Society, eloquently described wilderness medicine by its remoteness, physiology, need for improvisation, and dependence on clinical examination and judgment. Ongoing basic research and epidemiology continue www. Data from U. National Parks indicate that the most common injuries treated by wilderness medicine specialists are soft-tissue lesions, sprains, strains, and lower-extremity fractures.
Greer, Auerbach, and Kizer, from northern California. Its objectives are to advance wilderness medicine health care, education, and research. As the journal matured, its name was changed to Wilderness and Environmental Medicine. It is published quarterly and contains articles on bench and clinical research as well as editorials.
An additional resource is the quarterly newsletter Wilderness Medicine Magazine www. They are indexed and published in the journal Wilderness and Environmental Medicine. Areas of interest The field of wilderness medicine encompasses many areas of interest. Several core areas of key interest within wilderness medicine are discussed in this section. Pharmacologic management usually begins with acetazolamide and glucocorticoid steroids. Dive-specific injuries include decompression illness and barotrauma.
The incidence of decompression illness appears to be stable across recreational, professional, and scientific venues 0. Scientific diving has the lowest rate of injury. This variation is related to local fauna as well as the availability or lack of anti-venoms. Some envenomations, such as from Cubozoa jellyfish, can lead to massive adrenergic surge and cardiovascular collapse.
A leading cause of trauma mortality is head injury after a fall from height during hiking, rock climbing, mountain biking, and snow-related activities. Although most traumatic injuries are "minor" and involve the lower extremities, they often end outdoor activities and extended trips.
In rare events, trauma involves multiple systems and becomes life-threatening. World J Emerg Med, Vol 5, No 1, This category of wilderness medicine includes injuries sustained in motor vehicle crashes that occur during travel to and within remote areas.
Heatstroke is a complex process that involves cellular dysfunction, cardiac conduction dysfunction, release of pro-inflammatory cytokines, concomitant intravascular depletion, and subsequent circulatory collapse. In contrast to classic heatstroke, exertional heatstroke can occur even in moderate temperatures, especially among endurance wilderness athletes.
Under these circumstances, skin wetting and aggressive fanning can be used in an attempt to lower the patient's temperature. This technique might induce shivering, but there is no evidence suggesting that the concomitant heat production conflicts with the attempt to lower the core temperature.
Interestingly, hypothermia can even occur in temperate climates. Improvised and commercial methods for preventing further body heat loss are being developed. In some cases, prolonged resuscitation will be successful in achieving a positive neurologic outcome.
But, in remote settings, the required resources are usually not available. Reperfusion-ischemia injury is possible, and repeated thawing and refreezing is particularly damaging. Recent practice guidelines from the Wilderness Medical Society discuss the dichotomy between intentional field rewarming of a frozen body part, with maintenance of thawed tissue, and keeping the tissue frozen when the risk of re-freezing is significant.
Debridement of nonhemorrhagic blisters might be beneficial, but evidence is lacking. In the past, a "wait-and-see" approach was used to determine demarcation of the frozen area; now, tissue viability can be determined rapidly with advanced imaging such as magnetic resonance angiography or www. Victims caught in an avalanche are subjected to tremendous traumatic forces and are at risk of suffocation and, eventually, hypothermia.
The severity of avalanche injury is generally based on several factors: depth of burial, length of burial, airway obstruction, and concurrent trauma. Significant advances have been achieved in hemorrhage control with tourniquets and hemostatic agents, surgical cricothyroidotomy, intraosseous access, needle decompression, pain management, prophylactic antibiotics, and low-volume field resuscitation.
These advances are now crossing over to civilian EMS systems, tactical units, and wilderness medicine. Detailed information is still being collected, but general trends can be described. The most common injuries are soft-tissue lesions e. Search and rescue missions are often used for missing children, recreationalists, and individuals with developmental delay, autism, Alzheimer's disease, or dementia.
Both are practiced under sudden, unexpected, difficult, and austere conditions and have an inherent delay in emergency response and evacuation. Disaster conditions can be created in urban, suburban, and rural locations and are all associated with delays in emergency response, extraction, and evacuation to medical resources.
Diseases that are typical in wilderness or remote settings can emerge in the aftermath of disasters. Although dramatic scenarios such as crush injuries and amputations grab news media attention, the basics of hygiene and water sanitation are just as critical in disaster management as is the deployment of trained response personnel into devastated areas. Real-time ultrasound images have even been transmitted from the International Space Station.
The topics addressed in these guidelines include: high-altitude illness, frostbite, l i g h t n i n g ,  e y e i n j u r i e s ,  e p i n e p h r i n e ,  use of extrication devices in crevasse rescue,  exercise-associated hyponatremia,  spine trauma management,  heat-related illness,  anesthesia and pain management in press , wound management pending , hypothermia pending , drowning and immersion injuries pending.
They are based on case series and expert consensus, because, for many topics, research studies using randomized controls have not yet been conducted. The guidelines were developed in accordance with the templates suggested by the American College of Chest Physicians. It sponsors a variety of meetings in North America: an annual summer meeting, an annual winter meeting, and a fall specialty meeting organized around themes such as travel medicine, desert medicine, or environmental health.
The World Congress in Wilderness Medicine has met every 10 years 9 since , providing a forum for the exchange of current ideas and concepts related to wilderness medicine. Several other professional societies play important roles in wilderness medicine. The International Society of Travel Medicine www.
ISTM is involved in global monitoring of infectious diseases. Together with the Centers for Disease Control and Prevention CDC , ISTM manages Geosentinel, a global surveillance network for infectious diseases that provides nearly realtime data for analysis of evolving disease patterns.
The International Commission for Alpine Rescue www. ICAR publishes recommendations on both medical and technical issues for a variety of issues facing mountain rescue teams. Fellowships The purpose of wilderness medicine fellowships is to develop academic leaders in the specialty.
Multiple postgraduate fellowships are based in emergency medicine and family medicine graduate medical education programs. Generally, they have a research component, a teaching component, and a field component. A typical pattern is 1 year of training, with part-time clinical attending duties and part-time wilderness medicine training. The program at the University of California, Fresno, has an optional 1-year extension to obtain a master's degree in public health.
The program at George Washington University also offers the opportunity to complete a master of science or a master of public health degree. The original and best known wilderness medicine fellowship is based at Stanford University in Palo Alto, California.
The Society for Academic Emergency Medicine lists eight other wilderness medicine fellowships associated with emergency medicine residency programs.
Several family medicine programs also host wilderness medicine fellowships: the Montana Family Medicine Program www. Academy of wilderness medicine Under the auspices of the Wilderness Medical Society, the Academy of Wilderness Medicine offers a fellowship that provides rigorous education through a hour core curriculum as well as requirements for service, teaching, research, and experience. As of June , the Academy recognizes more than fellows as well as more than fellowship candidates.
This program offers advanced, post-fellow certification in the participant's chosen sub-discipline within the scope of wilderness medicine. The master's program is developed by the student and a mentor and must meet requirements in education, scholarly activity, and experimental activity. For example, a master's program in the subspecialty of dive medicine could focus on the clinical management of decompression illness.
Most participants fulfill the requirements of their program within 2 to 5 years. The program is open to physicians, nurses, and paramedics who work in or aspire to work in austere environments. The hours of coursework blend didactic and practical education in wilderness medicine, technical rescue, and www.
This skill set crosses a number of disciplines, including expedition medicine, search and rescue operations, mountain guiding, ski patrol, and mountain recreation.
The program consists of four week-long sessions that should be completed within 2 or 3 years. Participants must pass written and skills examinations to complete the program. Student interest groups The Wilderness Medical Society supports student interest groups that sponsor lecture series, workshops, and outdoor trips in conjunction with their sponsoring medical schools and faculty advisors.
The events are organized by medical students, often in their second year of training. As of July , approximately 43 of these interest groups, most of them in the United States and Europe, were active and operational. In addition, a number of emergency medicine and family medicine training programs in the United States offer 1- to 4-week electives in wilderness medicine for medical students and residents see below.
Schools of wilderness medicine Training in wilderness medicine is decentralized. Wilderness medicine courses for advanced care providers are available as well, e. Grants Charles S. Structural and functional changes of the human macula during acute exposure to high altitude.
