BACKGROUND: Salicylate poisoning is a common problem with appreciable morbidity and mortality. We present a case of a patient with a large aspirin ingestion who expired despite aggressive hemodialysis (HD).
CASE REPORT: A 35-year-old man arrived at the Emergency Department 7.5 h after ingesting 400 tablets of 325-mg aspirin. He was afebrile, the respiratory rate (RR) was 30 breaths/min, heart rate (HR) 120 beats/min, blood pressure (BP) 125/76 mm Hg, and oxygen saturation 99% on room air. His salicylate concentration was 89.6 mg/dL. His initial arterial blood gas: pH 7.48, pCO(2) 21 mm Hg, PaO(2) 97 mm Hg, and bicarbonate 15.8 mmol/L. His initial serum chemistry panel was normal. He received activated charcoal and intravenous hydration with sodium bicarbonate. Two hours after arrival, salicylate concentration was 91.6 mg/dL. The patient became agitated and HD was initiated; 22 h after presentation, repeat salicylate concentration was 88.4 mg/dL and his creatinine was 3.9 mg/dL. A second run of HD was performed. After this, his temperature had risen to 39.06°C (102.3°F), BP 122/64 mm Hg, HR 168 beats/min, RR 43 breaths/min, and oxygen saturation 95% (2 L nasal cannula). His confusion increased, and he died 40 h after his ingestion.
CONCLUSION: HD is widely advocated in managing severe salicylate intoxications, however, no consensus exists for the duration and best mode of therapy. Patients with severe salicylate poisonings may require extended durations of HD to effectively mitigate toxicity. Additional study is warranted to determine optimal therapy in severe salicylate intoxications.
