Area of Science:

  • Anesthesiology
  • Remote Medicine
  • High-Altitude Physiology

Background:

  • Clinical need for safe anesthesia in remote, high-altitude settings.
  • Limited anesthetic options for primary care physicians in underserved areas.

Purpose of the Study:

  • To document the efficacy and safety of ketamine anesthesia in a remote hospital at 3,900 m.
  • To evaluate ketamine's suitability for use by non-specialist physicians.

Main Methods:

  • Administration of low-dose ketamine (2.0 mg/kg) for anesthesia.
  • Use of midazolam as premedication to prevent emergent nightmares.
  • Management of patients in a quiet recovery area.

Main Results:

  • Ketamine provided dissociative anesthesia without depressing hypoxic drive or airway reflexes.
  • Supplemental oxygen was not consistently required; physical stimulation aided recovery.
  • Emergent nightmares were avoided with midazolam premedication and a calm recovery environment.

Conclusions:

  • Ketamine with midazolam is a safe and effective anesthetic method for very high altitudes.
  • This technique requires no specialized equipment or training beyond basic airway management skills.
  • It provides a viable anesthetic solution for clinicians in remote and high-altitude environments.
