RESUMEN
Salicylate poisonings are divided into acute and chronic syndromes. The most challenging aspect of the management of aspirin-poisoning may be recognition of subtle signs and symptoms of chronic, unintentional overdose. Chronic poisoning typically occurs in elderly as a result of unintentional overdosing on salicylates used to treat chronic conditions. Treatment is directed toward preventing intestinal absorption of the drugs and enhanced elimination. After the first-line treatments, aspirin overdose with its complications of hemodynamic, electrolyte and acid-base issues, is best managed by prompt hemodialysis. We report a case of a 87-year-old woman, who presented with acute on chronic salicylate poisoning. After early continuous venovenous hemodiafiltration, old woman made a good recovery from the salicylism but suffered paralytic ileus caused by aspirin enteroliths. Physician can decide a prompt hemodialysis for salicylate-poisoned patients, who worsen clinical courses despite of first-line therapies.
