title: Studies on premedication and ventilatory responses to minaxolone.
abstract: The effect of three premedications on induction, maintenance and recovery characteristics of minaxolone as a supplement to nitrous oxide and oxygen anesthesia were studied in 70 patients. Morphine and atropine premedication provided superior operative conditions with fewer side-effects when compared with atropine alone or diazepam and atropine. Recovery was significantly longer after minaxolone compared with a similar group of patients given Althesin. The ventilatory responses to the induction of anesthesia with minaxolone were measured in 25 patients. All patients showed an increase in respiratory frequency and a decrease in tidal volume. This effect was most marked in the group premedicated with diazepam and atropine.
