Retrieval of Additional Epinephrine from Adrenaclick-Style Epinephrine Autoinjectors
Anaphylaxis is a life-threatening allergic reaction involving multiple organ systems that can result in significant morbidity and mortality if left untreated. Epinephrine is the mainstay of treatment. Most episodes of anaphylaxis resolve after a single dose of epinephrine, but biphasic and protracted courses of anaphylaxis are well described. The need for additional doses of epinephrine poses a significant challenge in the wilderness setting, because patients and providers may only carry a single autoinjector.Acute Hamstring Muscle Tears in Climbers—Current Rehabilitation Concepts
Acute hamstring injuries are often caused by the heel hook technique. This technique is unique to climbing and causes injury to muscular and inert tissues of the posterior thigh. The heel hook is used by climbers during strenuous ascent on overhanging walls and when crossing difficult terrain. The technique reduces the amount of upper body strength required during strenuous climbing because the climber’s center of mass is retained within the base of support. The heel hook is stressful collectively for the hamstring muscle group and musculotendinous junction.Physiology of the pituitary, thyroid, parathyroid and adrenal glands
Endocrinology is the study of hormones, endocrine glands and related diseases. Understanding basic hormonal physiology is essential for surgeons to manage patients with endocrine disorders. In this article we present the fundamental physiological mechanisms related to pituitary, thyroid, parathyroid and adrenal hormonal production, secretion and action. Moreover the methods used in the investigation for hormonal disturbances associated with these glands, resulting in excess or deficient secretion, are introduced.Implementing Wilderness Medicine Training for Undergraduate Medical Students in the UK
The UK General Medical Councils’ approved curricula share only 3 topics with the Fellowship in the Academy of Wilderness Medicine core curriculum, suggesting an underrepresentation of wilderness medicine (WM) in medical education. We developed a 5-mo course to address the gaps between these curricula to run in parallel with the conventional curriculum. Our 71-h course is composed of lectures and practical exercises. We set out to evaluate the effectiveness of this concept and assess its suitability for use by other institutions.Fresh Low Titer O Whole Blood Transfusion in the Austere Medical Environment
Massive hemorrhage is an immediate threat to life. The military developed the Tactical Combat Casualty Care guidelines to address the management of acute trauma, including administration of blood products. The guidelines have been expanded to include low titer O whole blood, which is in limited use by the military. This proposal describes how the transfusion of fresh whole blood might be applied to the remote civilian environment. In doing so, this life-saving intervention may be brought to the austere medical environment, allowing critically hemorrhaging patients to survive to reach definitive medical care.Emergency Medical Training for the Commercial Fishing Industry: An Expanded Role for Wilderness Medicine
This article describes the conception, implementation, and evaluation of a wilderness medicine–based first aid class for the commercial fishing industry. Commercial fishing is a dangerous occupation in the United States. Currently, commercial fishermen often only have access to basic first aid classes. Because of its focus on austere environments, hazardous conditions, and distance from definitive medical care—hallmarks of commercial fisheries—wilderness medicine offers a more appropriate approach to decreasing morbidity and mortality in the industry.An Experience of Improvised Laryngoscopy
Airway management in the wilderness runs the gamut from basic airway support to endotracheal intubation. Fortunately, direct laryngoscopy is a seldom called upon skill in expedition medicine. However, the medical skills required during a mission or expedition are never truly known in advance. Improvisation during evolving medical events is a mainstay of expedition medicine education and practice. It is unlikely, given constraints of weight and size of expedition medical kits, that a conventional laryngoscope would find its way into a standard “go bag.” Faced with the real but rare event of needing to intubate a patient in an austere environment, how can improvisation be used? Multiple ideas for improvised laryngoscopes can be found in the wilderness medicine literature, but which, if any, of these devices have true clinical utility? To this end, participants of a recent Wilderness Medical Society preconference in medical elements of light search and rescue were given the opportunity to devise and construct their own improvised laryngoscopes and attempt intubation of a training mannequin.
