Case: A woman aged in her 20s ingested approximately 99 g acetylsalicylic acid, and was transported to our hospital 2 h later. She was lucid, but complained of hearing loss and tinnitus. We performed gastric lavage and gave her activated charcoal several times. We attempted to maintain the urinary pH at 7.5 and output above 100 mL/h while preparing for urgent hemodialysis. Outcome: It was revealed after discharge that the blood concentration of acetylsalicylic acid was 103.8 mg/dL on admission (lethal dose level) and had decreased to 35.4 mg/dL by the next morning. The half-life was 8.5 h. Conclusion: Hemodialysis is strongly recommended for patients who take a lethal dose of acetylsalicylic acid. However, by carefully evaluating the vital signs and urinary output and pH, while preparing for emergency hemodialysis, we consider that it is possible to treat acetylsalicylic acid poisoning by alkaline diuresis and critical supportive care.
