Comparison of the efficacy of continuous intravenous infusion versus intramuscular injection of epinephrine for initial anaphylaxis treatment.

Continuous intravenous infusion of epinephrine for the treatment of anaphylaxis may be safe, has fewer adverse events, improves symptoms, and is relatively easy to administer under ready conditions. CIV infusion of epinephrine may also reduce the incidence of biphasic reactions.
