Freon: Accidental ingestion and gastric perforation
2008
Introduction. Freons generally have a low order of toxicity, but exposure to relatively high concentrations (>100 ppm) may produce adverse effects on health. Currently, intoxication reports are unintentional inhalation of CFCs. We report an unintentional ingestion of a mixture of CFCs and the results of a rat study. Case Report. A 43-year-old man was admitted to the Emergency Department with a chief complaint of acute abdominal pain that developed minutes after he ingested a clear liquid in a water glass, which contained a mixture of Freon and water. Subsequent surgical evaluation revealed perforation of the stomach and necrosis of the stomach wall. He developed a transient rise in his hepatic transaminases, which resolved spontaneously, and fully recovered from his surgery. Methods. A murine model of the injury was created to evaluate threshold concentration and effect of time on injury grade. Results. Injury grade increased with delay to histologic analysis from 8 to 24 hours after exposure to Freon. In...
