A Review of Urologic Conditions in Remote and Austere Environments: Presentation, Evaluation, and Management.

The objective of this review is to provide recommendations on the evaluation and management of urologic conditions in a resource-poor or austere setting from the perspective of the urological literature. The material was synthesized predominantly from urologic society guidelines and journals to bring additional urology-focused insight to the topic to complement the currently available literature, which is largely based on recommendations from nonurologic specialties. We sought to provide a reference guide from a urology-based framework that encourages a collaborative multidisciplinary approach to the development of a resource that serves those in a wilderness, austere, or resource-poor setting.

Wilderness Medical Society Clinical Practice Guidelines for the Management of Exercise-Associated Hyponatremia: 2019 Update.

Exercise-associated hyponatremia (EAH) is defined by a serum or plasma sodium concentration below the normal reference range of 135 mmol·L-1 that occurs during or up to 24 h after prolonged physical activity. It is reported to occur in individual physical activities or during organized endurance events conducted in environments in which medical care is limited and often not available, and patient evacuation to definitive care is often greatly delayed. Rapid recognition and appropriate treatment are essential in the severe form to increase the likelihood of a positive outcome. To mitigate the risk of EAH mismanagement, care providers in the prehospital and in hospital settings must differentiate from other causes that present with similar signs and symptoms. EAH most commonly has overlapping signs and symptoms with heat exhaustion and exertional heat stroke. Failure in this regard is a recognized cause of worsened morbidity and mortality. In an effort to produce best practice guidelines for EAH management, the Wilderness Medical Society convened an expert panel in May 2018. The panel was charged with updating the WMS Practice Guidelines for Treatment of Exercise-Associated Hyponatremia published in 2014 using evidence-based guidelines for the prevention, recognition, and treatment of EAH. Recommendations are made based on presenting with symptomatic EAH, particularly when point-of-care blood sodium testing is unavailable in the field. These recommendations are graded on the basis of the quality of supporting evidence and balanced between the benefits and risks/burdens for each parameter according to the methodology stipulated by the American College of Chest Physicians.

Wilderness Medical Society Clinical Practice Guidelines for Water Disinfection for Wilderness, International Travel, and Austere Situations.

To provide guidance to clinicians, the Wilderness Medical Society convened experts to develop evidence-based guidelines for water disinfection in situations where the potability of available water is not ensured, including wilderness and international travel, areas affected by disaster, and other areas without adequate sanitation. The guidelines present the available methods for reducing or eliminating microbiologic contamination of water for individuals, groups, or households; evaluation of their effectiveness; and practical considerations. The evidence evaluation includes both laboratory and clinical publications. The panel graded the recommendations based on the quality of supporting evidence and the balance between benefits and risks or burdens, according to the criteria published by the American College of Chest Physicians.

Wilderness Medical Society Clinical Practice Guidelines for the Treatment and Prevention of Drowning: 2019 Update.

The Wilderness Medical Society convened a panel to review available evidence supporting practices for acute management and treatment of drowning in out-of-hospital and emergency medical care settings. Literature about definitions and terminology, epidemiology, rescue, resuscitation, acute clinical management, disposition, and drowning prevention was reviewed. The panel graded available evidence supporting practices according to the American College of Chest Physicians criteria and then made recommendations based on that evidence. Recommendations were based on the panel's collective clinical experience and judgment when published evidence was lacking. This is the first update to the original practice guidelines published in 2016.

Wilderness Medical Society Clinical Practice Guidelines for Spinal Cord Protection.

The Wilderness Medical Society reconvened an expert panel to update best practice guidelines for spinal cord protection during trauma management. This panel, with membership updated in 2018, was charged with the development of evidence-based guidelines for management of the injured or potentially injured spine in wilderness environments. Recommendations are made regarding several parameters related to spinal cord protection. These recommendations are graded based on the quality of supporting evidence and balance the benefits and risks/burdens for each parameter according to the methodology stipulated by the American College of Chest Physicians. Key recommendations include the concept that interventions should be goal oriented (spinal cord/column protection in the context of overall patient and provider safety) rather than technique oriented (immobilization). This evidence-based, goal-oriented approach does not support the immobilization of suspected spinal injuries via rigid collars or backboards.

Wilderness Medical Society Clinical Practice Guidelines for Diabetes Management.

The Wilderness Medical Society convened an expert panel in 2018 to develop a set of evidence-based guidelines for the treatment of type 1 and 2 diabetes, as well as the recognition, prevention, and treatment of complications of diabetes in wilderness athletes. We present a review of the classifications, pathophysiology, and evidence-based guidelines for planning and preventive measures, as well as best practice recommendations for both routine and urgent therapeutic management of diabetes and glycemic complications. These recommendations are graded based on the quality of supporting evidence and balance between the benefits and risks or burdens for each recommendation.

Forty Years on From an Event That Changed the Management of Trauma Around the World: What Actually Happened That Night Forty Years Ago?

The management of trauma has evolved significantly over the last 40 years. Seminal to this process was the development in Nebraska of a concept of trauma management that was promulgated as Advanced Trauma Life Support (ATLS). It has achieved global support and is considered by many to be the acme in trauma management. Every participant in an ATLS course remembers that an aviation accident in rural Nebraska was responsible for the nascence of the program but very few know the details of the crash. February 17, 2016, was the 40th anniversary of the accident. This article extracts the details of the flight, the crash, the search, the extrication, the reception at the nearby rural hospital, and the injuries from both the official report and the published, personal records of survivors of the crash. The effect of ATLS can be debated elsewhere and its future questioned. However, the article concludes by highlighting the fortitude and resilience of the human spirit that were demonstrated that night under incredible circumstances.
