Area of Science:

  • Emergency Medicine
  • Wilderness Medicine
  • Trauma Care

Background:

  • Wilderness rescues present unique challenges due to environmental factors and patient condition.
  • National Park Service (NPS) Emergency Medical Services (EMS) operate in remote and demanding settings.

Observation:

  • A 43-year-old male hiker sustained a 25-foot fall in Sequoia National Park, resulting in a right femur fracture.
  • The patient presented with hypothermia and hypovolemia, exacerbated by harsh environmental conditions including weather and high altitude.
  • The hiker's significant size (6'1", 250 lbs) presented additional logistical challenges during the rescue operation.

Findings:

  • The rescue operation lasted 53 hours, involving a 1,500 vertical foot carry-down before helicopter evacuation.

Related Experiment Videos

  • The patient was diagnosed with a comminuted subtrochanteric right femur fracture upon arrival at University Medical Center.
  • Surgical intervention was required for the definitive treatment of the femur fracture.

    • Implications:

    • This case highlights the critical importance of specialized training and equipment for wilderness EMS in complex rescue scenarios.
    • Effective management of hypothermia, hypovolemia, and severe fractures is crucial for patient survival in remote environments.
    • Understanding the impact of patient size and environmental conditions is vital for planning and executing successful long-line rescues and medical evacuations.
