Halothane induced hepatitis: Case report

Abstract

Halothane as a cause of hepatitis is rare and may be overlooked when evaluating a patient with sudden onset jaundice. A 34-year-old lady, a nurse, presented to the liver clinic with sudden onset non - pruritic jaundice. Viral and collagen serological tests were all normal, malaria and sickling tests were negative, but transaminases were elevated. She reported inadvertent exposure to halothane in surgical theatre where she works. She improved on conservative management, then had a re-exposure to halothane after three weeks and developed a similar clinical picture, which improved on conservative management. In an area endemic of malaria, hepatitis and haemolysing conditions like sickle cell anaemia, the diagnosis of halothane hepatitis requires high index of suspicion. The mechanism of halothane-induced hepatic damage in this patient is very likely idiosyncratic. This is because of the modest dose at first exposure and more severe clinical picture at re-exposure.
