[Effect of M1 blocker or H2 blocker on gastric secretion during anesthesia and surgery].
Effect of pirenzepine, famotidine or a combination of both agents on gastric secretion during anesthesia and surgery was evaluated in 42 surgical patients ranged in age from 17 y to 70 y. They underwent orthopedic, ophthalmic, ENT, plastic, oral or non-abdominal surgery under either neuroleptanesthesia or enflurane anesthesia. They received either pirenzepine 10 mg, famotidine 20 mg or the combination of both agents intravenously just before the induction of anesthesia. Volume and acidity of gastric juice were measured during 3 hours after the administration of these agents. A continued decrease in volume and acidity of gastric juice was observed 3 hrs after the administration of the agents both in the pirenzepine group and in the famotidine group. Efficacy of the combination of pirenzepine and famotidine on gastric secretion tended to be more prominent than that of either pirenzepine or famotidine alone.
