Popis: The toxicokinetics of pediatric intravenous (IV) acetaminophen (APAP) in overdose is not well described and few case reports with serial APAP concentrations allowing for calculations of half-life exist. Here, we report toxicokinetic data from a case of an unintentional IV APAP overdose in a 12-month-old male who was treated with NAC. Case Report: A 12-month-old (former 24 week gestational age), 8.7 kg male was hospitalized after an uneventful colostomy reversal. In the postoperative unit, the patient unintentionally received 1000 mg IV (114.9 mg/kg) acetaminophen instead of the intended 100 mg IV. Serial acetaminophen concentrations were drawn. The patient received IV Nacetylcysteine and ultimately had no adverse outcomes. Discussion: This case report adds to the existing literature regarding toxicokinetics of IV APAP in infants. Our patient had a calculated ke of 0.263 h-1, correlating with a half-life of 2.63 hours. Based on current available data, the half-life of IV APAP in infants varies (2.6 to 4.9 hours). The reason for this variation is unknown and further research is needed in this area.
