naloxone and Jaundice

Five groups of 10 patients received thiamylal, enflurane, nitrous oxide-oxygen anesthesia for elective cholecystectomy. The common bile duct was intubated via the cystic duct with a 16-g plastic catheter, and the control intraductal pressure was measured. Patients then were given equi-analgesic doses of fentanyl, morphine, meperidine, butorphanol, or placebo intravenously, and the common bile duct pressure was recorded for 20 min. Fentanyl, morphine, and meperidine significantly increased pressure in the common duct (P less than 0.001). Butorphanol produced only insignificant changes. Naloxone given 20 min later significantly (P less than 0.001) decreased pressure in patients given fentanyl, morphine, and meperidine. Naloxone given without narcotics caused an increase in pressure that, although statistically significant (P less than 0.03), was clinically insignificant. In five additional patients anesthetized with thiamylal, nitrous oxide-oxygen and intermittent doses of fentanyl, common bile duct pressures were normal.

Pruritus is a manifestation of chronic liver disease. Epstein-Barr virus (EBV) infection often presents as infectious mononucleosis and mild hepatitis. Severe pruritus in the setting of infectious mononucleosis and persistent marked hyperbilirubinaemia is exceedingly uncommon. To the best of our knowledge, we present the first case of a patient with EBV hepatitis and severe pruritus that was successfully treated with an ultra-low dose of intravenous naltraxone.
