title: [Effects of high-dose fentanyl on intraductal pressure in the choledochoduodenal junction in dogs].
abstract: Changes in intraductal pressure in choledochoduodenal junction were studied following intravenous administration of fentanyl in dogs. The intraductal pressure was measured with constant-rate infusion method. A statistically significant increase in the intraductal pressure was demonstrated after the intravenous administration of fentanyl 5 micrograms.kg-1 and 75 micrograms.kg-1. The increase in intraductal pressure following fentanyl administration at a dose of 75 micrograms.kg-1 persisted for more than 5 hours. We conclude that in case of intravenous high-dose fentanyl administration special attention should be paid to spasm of choledochoduodenal sphincter.
