Oleander- und Ligustervergiftung bei einem Pferd

Summary

Presentation of clinical symptoms, therapy and outcome in a horse with plant intoxication (oleander, liguster). Furthermore raising awareness for the preliminary report of toxic plant ingestion in conjunction with clinically displayed symptoms. Patient and history: A five-year-old gelding was presented with anorexia, ataxia, mydriasis, tachycardia and paralytic ileus. The gelding had a history of possible ingestion of oleander and liguster four days before admission to the clinic. He had been treated for colic and borrelia infection prior to presentation. Results: Laboratory results indicated renal insufficiency and mild dehydration. The Electrocardiogram displayed ventricular extrasystoles. In gastroscopy ulcerations in pharynx, esophagus and stomach were visible. Despite the attempt to stabilize the state with infusions and to inhibit further toxin absorption, the horse died eight hours after admission to the clinic. Conclusions: Early diagnosis of possible toxin ingestion by combining history of the patient and clinical symptoms can be lifesaving. Immediate measures to prohibit further toxin absorption, to fasten toxin elimination and to start with accompanying symptomatic treatment is of utmost importance.
