[Effect of pirenzepine on gastric secretion during anesthesia and surgery].
Effect of pirenzepine on gastric secretion during anesthesia and surgery was evaluated in 46 surgical patients ranged in age from 18 to 68 years. The patients underwent orthopedic, ophthalmic, ENT, plastic or non-abdominal general surgery under neuroleptanesthesia except two patients who had enflurane or isoflurane anesthesia. They received either pirenzepine 10 mg, 20 mg or the combination of pirenzepine 10 mg and famotidine 20 mg intravenously just before the induction of anesthesia. Volume and acidity of gastric juice were measured for 3 hours after the administration of these agents. Decrease in volume and acidity of gastric juice after pirenzepine 10 mg as well as after pirenzepine 20 mg continued for more than 3 hrs after the administration of the agents. Efficacy of the combination of pirenzepine and famotidine on gastric secretion was more prominent than that of pirenzepine alone in a double dose.
