Emergency Care for High-Altitude Trekking and Climbing

Introduction: High altitude regions are characterized by harsh conditions (environmental, rough terrain, natural hazards, and limited hygiene and health care), which all may contribute to the risk of accidents/emergencies when trekking or climbing. Exposure to hypoxia, cold, wind, and solar radiation are typical features of the high altitude environment. Emergencies in these remote areas place high demands on the diagnostic and treatment skills of doctors and first-aiders. The aim of this review is to give insights on providing the best possible care for victims of emergencies at high altitude. Methods: Authors provide clinical recommendations based on their real-world experience, complemented by appropriate recent studies and internationally reputable guidelines. Results and Discussion: This review covers most of the emergencies/health issues that can occur when trekking or during high altitude climbing, that is, high altitude illnesses and hypothermia, freezing cold injuries, accidents, for example, with severe injuries due to falling, cardiovascular and respiratory illnesses, abdominal, musculoskeletal, eye, dental, and skin issues. We give a summary of current recommendations for emergency care and pain relief in case of these various incidents.

Injuries Sustained at Yellowstone National Park Requiring Emergency Medical System Activation

OBJECTIVE

Outdoor-related activity has been on the rise in recent years, and hiking and backpacking are among those activities with the largest growth in participation. As the number of participants with varying experience increases, it is expected that there will be an increase in injuries related to these activities. Little empirical data exist related to outdoor injury types and rates. Our objectives were to determine incidence and frequency of injuries related to outdoor activity and requiring emergency medical system (EMS) activation at a national park.

METHODS

This retrospective study examines injuries within Yellowstone National Park. Subjects were selected from a database containing all EMS calls within Yellowstone National Park from calendar year 2003 through 2004. Data collected included age, gender, type of injury, location, activity at the time of injury, and EMS response.

RESULTS

There were 306 injuries reviewed. The mean age of patients was 40.9 years (SD: 23.0), and the group comprised 49.0% males. Emergency medical system transport was not required in 59.2% of injuries, and of those transported, 58.4% of patients required basic life support only. Of all injuries, 77.4% involved soft tissue, including lacerations. Hiking and walking accounted for 38.0% of all injuries, and 56.0% of those injuries involved the lower extremity. Only 8.8% of the injuries involved fractures and/or dislocations.

CONCLUSIONS

In this study of EMS responses at a national park, the majority of injuries sustained were minor in nature. More than one third of injuries occurred while patients were hiking or walking, and most of those injuries involved the lower extremity. These results will help optimize resource planning in the national park setting.
