AN ASSESSMENT OF GASTRIC EMPTYING BY BREATHALYSER

Abstract
1 A breathalyser has been used to measure blood alcohol levels at short intervals to produce an absorption curve which we have shown is reproducible. 2 Changes in the rate of absorption which reflect changes in gastric emptying times produced by metoclopromide and propantheline have been demonstrated. 3 The breathalyser technique described appears to offer a simple method of studying the effects of drugs on the rate of gastric emptying.
