    Area of Science:

    • Forensic Toxicology
    • Analytical Chemistry

    Background:

    • Barbiturate poisonings, though less common, remain a significant forensic challenge.
    • Veterinary euthanasia solutions and discontinued pharmaceuticals present unique toxicological scenarios.

    Observation:

    • Two fatal cases of barbiturate ingestion were investigated.
    • Case 1: Suicidal ingestion of a pentobarbital-containing veterinary euthanasia preparation.
    • Case 2: Suicidal ingestion of vinbarbital, a drug not currently marketed in the US.

    Findings:

    • Extremely high blood and liver concentrations of pentobarbital were detected in the first case.
    • Identification of pentobarbital and vinbarbital confirmed using infrared spectrophotometry and thin-layer chromatography.
    • Quantification of both barbiturates was achieved through ultraviolet spectrophotometry.

    Implications:

    • These cases underscore the critical need for robust analytical procedures in identifying and quantifying drugs in biological samples.
    • Definitive toxicological analysis is essential for accurate post-mortem investigations, even with uncommon or discontinued substances.
    • The findings support the continued use and development of advanced analytical techniques in forensic science.
