Hydrocarbon Associated Toxicities: a Case Series and Review of Literature

Abstract

Background: Hydrocarbon associated toxicity (HAT) is an emerging threat related to wide scale industrialization and easy access to hydrocarbon-containing chemical compounds. Hydrocarbons have a unique toxicological profile and the principles of managing related toxidromes are considerably different from other toxins.<br /> Case reports: Here, we present a case series and in-depth review of the existing literature to show the risks associated with these seemingly harmless chemicals, and the approved guidelines for treating exposed patients. In all three cases, the hydrocarbon was a diluent for a pesticide. The amount of pesticide ingested was nontoxic, while the hydrocarbons caused a dose-independent physical toxicity to the lungs.<br /> Discussion: Hydrocarbon associated toxicities often go unnoticed because of their usage as diluents for various other toxic chemicals. Their treatment usually differs from other toxins that may have been consumed with them, albeit in insignificant quantities.<br /> Conclusion: Recognition of a hydrocarbon diluent in a consumed toxin marks the first step in the correct treatment. Correct labeling of chemical solutions containing hydrocarbons would go a long way in identifying these toxins.
