Determination of total gastric volume, gastric secretion and residual meal using the double sampling technique of George.

摘要: In literature several techniques are described for the measurement of gastric emptying. One these is double sampling technique George which has advantage that it enables multiple measurements total volume in one experiment. order to estimate net emptying, however, important differentiate between test meal present stomach and secretion. study George's was extended with a calculation procedure secretion outflow. An vitro experiment carried out showed an accuracy 5-10% this method. vivo comparison made Hunt's chloride technique, used estimating Sixteen subjects participated 60 minute water as meal. Regression analysis high degree correlation (R2 = 0.99) method proposed The data obtained indicate gives reliable estimation emptying simple do no further have be other than those needed
