Most methods of measurements of gastric emptying rely on the serial estimation of intragastric volume and do not separately account for the volume of fluid which has been added to the meal by gastric secretion, duodenal reflux, or swallowed saliva. The volume emptied is therefore underestimated. A method of measuring gastric emptying using [125I]RIHSA and the Volémetron is presented. The volume of fluid added to the meal is taken into consideration in this method, giving a more accurate reflection of gastric emptying. Using this method in the dog, emptying was found to be linear rather than exponential.
大多数测量胃排空的方法依赖于对胃内体积的连续估计，并未分别考虑因胃分泌、十二指肠反流或吞咽唾液而添加到食物中的液体体积。因此，排空的体积被低估了。本文介绍了一种使用[125I]RIHSA和Volémetron测量胃排空的方法。该方法考虑了添加到食物中的液体体积，能更准确地反映胃排空情况。在狗身上使用这种方法时，发现排空是呈线性而非指数性的。
