Which inhaled anesthetic carries a rare risk of immune-mediated hepatic necrosis caused by its metabolism into reactive trifluoroacetylated intermediates?

  1. Sevoflurane
  2. Halothane
  3. Enflurane
  4. Nitrous oxide
Show answer and explanation

Correct answer: Halothane

Halothane undergoes significant hepatic metabolism (up to 20%). In rare cases, this leads to the formation of reactive metabolites that can trigger an immune-mediated hepatic necrosis, particularly upon repeated exposure.
