Schrickel JW, Lewalter T, Luderitz B, Nickenig G, Klehr HU, Rabe C: Recovery from ultra-high dose organophosphate poisoning after "in-the-field" antidote treatment: potential lessons for civil defense. J Emerg Med. 2009 Oct;37(3):279-82. Epub 2008 Feb 20.
Organophosphate poisoning is associated with a high mortality rate due to respiratory failure, dysrhythmias, and multi-organ failure. We report two cases of survival after "in-the field" antidote treatment of very severe organophosphate poisonings. Two patients orally ingested large amounts of the organophosphorous agent oxydemeton-methyl in suicide attempts, resulting in the hypercholinergic syndrome in both. Resuscitation included early administration of antidote by emergency medical personnel as well as high-dose atropine. Plasma levels of pseudo cholinesterase were initially very low in both patients. Long-term mechanical ventilation was necessary, and both patients developed aspiration pneumonia. At discharge, no major neurological deficits were present. Prompt antidote treatment and aggressive supportive emergency and intensive care unit therapy contribute to improved survival after acute organophosphate poisoning. We believe that in cases of mass poisonings--for example, terrorist activity--therapy must be available on the scene as soon as possible. This also may require decentralized antidote storage. |
