Acute Cyanide Poisoning: Hydroxocobalamin and Sodium Thiosulfate Treatments with Two Outcomes following One Exposure Event

Abstract EN

Cyanide is rapidly reacting and causes arrest of aerobic metabolism.

The symptoms are diffuse and lethal and require high clinical suspicion.

Remediation of symptoms and mortality is highly dependent on quick treatment with a cyanide antidote.

Presently, there are two widely accepted antidotes: sodium thiosulfate and hydroxocobalamin.

These treatments act on different components of cyanide’s metabolism.

Here, we present two cases resulting from the same source of cyanide poisoning and the use of both antidotes separately used with differing outcomes.
