Abstract

Sixty patients anesthetized with nitrous oxide-oxygen-halothane, who received pancuronium for the maintenance of muscular relaxation were divided into three group of twenty each. Ath the end of anesthesia, the patients of Group l received in 1.0mg atropine travenously and neostigmine 2.0mg: those in Group ll glycopyrrolate 0.4mg and neostigmine 2.0mg. and those in Group lll atropine 0.5mg, glycopyrrolate 0.2mg and neostigmine 2.0mg. After that the changes in heart rate, arrhythmsia, blood pressure and oropharyngeal secretions were observed and evaluated. The results are as follows: 1) The safety and effectiveness of all groups in antagonizing the muscarinic actions of neostigmine were demonstrated. 2) Glycopyrrolate produced a significantly smaller change in heart rate than atropine. 3) There were no significant difference in the indicence of severe tachycardia in all groups respectively. 4) Glycopyrrolate is superior to atropine in the antisalivary action. 5) There were no more advantages in combined use of atropine and glycopyrrolate than that of atropine or glycopyrrolate separotely.
