Modification of antidote therapy for poisoning due to massive admission of paracetamol

Abstract

Background. Paracetamol poisoning is common all over the world, including in Russia. In 20–25% of cases, a massive dose of the drug is observed: more than 30–40 g of paracetamol at a time.The aim of the study was to demonstrate the efficacy of using an increased doses of acetylcysteine in the treatment of a massive paracetamol admission.Results. Patient G., 22 years old, took 70 tablets (35 g) of paracetamol for suicide 3 hours before admission to the hospital. The blood level of paracetamol 4 hours after taking it was 694.94 µg/mL. Upon admission to the hospital, acetylcysteine administering was started according to a 12-hour scheme. Subsequently, the administration of acetylcysteine was continued according to a 20-hour regimen with an increased dosage at the 2nd stage. Laboratory parameters, including aspartate aminotransferase and alanine aminotransferase, remained within the reference values during hospital stay. Conclusion. The case report we have presented shows the efficacy and expediency of using an increased doses of acetylcysteine in case of massive admission of paracetamol, which contributes to the prevention of the development of severe complications and a favorable course and outcome of the disease.
