Hydroxycobalamin/sodium thiosulfate as a cyanide antidote.

A H Hall, B H Rumack

    The Journal of Emergency Medicine
    |January 1, 1987
    PubMed
    Summary

    Hydroxycobalamin/sodium thiosulfate is a safe and effective antidote for cyanide poisoning. This combination offers a less toxic alternative to existing treatments, particularly when cyanide exposure is uncertain.

    Area of Science:

    • Toxicology
    • Emergency Medicine
    • Pharmacology

    Background:

    • Severe cyanide poisoning is difficult to diagnose without exposure history.
    • Smoke inhalation victims may suffer from cyanide and carbon monoxide toxicity.
    • Current U.S. cyanide antidote kits have inherent toxicity concerns.

    Purpose of the Study:

    • To review animal and human data on hydroxycobalamin/sodium thiosulfate as a cyanide antidote.
    • To evaluate the efficacy and safety of this combination.
    • To identify a less toxic alternative for cyanide poisoning treatment.

    Main Methods:

    • Review of published French case reports on hydroxycobalamin/sodium thiosulfate treatment.
    • Analysis of animal studies demonstrating safety and efficacy.
    • Examination of human data for clinical outcomes.

    Main Results:

    • Hydroxycobalamin/sodium thiosulfate has been used in France since 1970.
    • Both components are proven safe and effective in animal models.
    • Published human data, though limited, supports efficacy.

    Conclusions:

    • Hydroxycobalamin/sodium thiosulfate is an efficacious cyanide antidote.
    • This combination presents significantly lower inherent toxicity compared to other antidotes.
    • It is a desirable option, especially in uncertain poisoning cases.
