Common bile duct pressure changes after fentanyl, morphine, meperidine, butorphanol, and naloxone.

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.

Prevention of succinylcholine induced hyperkalemia by neurolept anesthesia and hexafluorenium in anephric patients.

Forty patients, half of them with normal kidney function, the other half anephric were included in the study. All received diphenhydramine, meperidine and atropine for premedication and droperidol, fentanyl, N2O and O2 for anesthesia. For endotracheal intubation and further relaxation 0.
