Double-peaked Acetaminophen Concentration Secondary to Intestinal Trauma.
???displayArticle.abstract???
BackgroundReduced gastrointestinal motility can alter the toxicokinetics of acetaminophen poisoning. We report a case of altered acetaminophen toxicokinetics due to delayed gastrointestinal absorption, likely secondary to intestinal trauma/surgery. Case ReportA 37-year-old woman ingested an unknown amount of acetaminophen and ethanol then stabbed herself in the abdomen. The initial acetaminophen was 1,285.9 μmol/L and the time of ingestion was not known. Intravenous acetylcysteine protocol was started. She developed an ileus post-surgery for the stab wounds. At 31 hours post-presentation, the acetaminophen returned undetectable, and the transaminases were normal. After the resolution of the ileus, repeated acetaminophen peaked at 363.3 μmol/L 52 hours post-admission. At 76 hours post-admission, the acetaminophen was undetectable, and transaminases and coagulation parameters were normal. ConclusionsReduction in gastrointestinal motility secondary to trauma and/or surgery must be considered when determining when to initiate or discontinue treatment as well as how long to monitor acetaminophen concentrations.
