Retrieval of additional epinephrine from auto-injectors.

Anaphylaxis is a challenging condition for any austere environment. It is unpredictable, has sudden onset and a high fatality rate, and is responsive only to epinephrine, a prescription medication. The Wilderness Medical Society has formally recommended that non-medical providers working in austere environments be trained to administer epinephrine. Medical providers frequently prescribe auto-injectors for this purpose due to their ease of use by nonmedical providers. However, auto-injectors have limitations in the wilderness environment, particularly due to their single-dose (or at most 2-dose) design. This paper describes an austere environment technique for obtaining multiple additional doses of epinephrine from auto-injectors that have already been used as designed.
