Abstract

PURPOSE

To examine the emptying times of broth and water, and explore the possibility of a cephalic influence on gastric emptying.

MATERIAL AND METHODS

On different days each of twelve healthy volunteers had meals of either 350 ml water or 350 ml broth. Subsequently ten volunteers had meals of water alone and of water followed by sham feeding with broth. The antral area was determined at sonography five times before the meal as a baseline, and every 1-4 minutes after the meal. The time until the antral area had decreased to 150% of baseline (T150) was determined and used as surrogate expression of gastric emptying time.

RESULTS

The mean T150 was for water 20.3 min (range 12-40), and was for broth significantly shorter 12.6 min (5-21), P = 0.0020. In the subsequent series the mean T150 was 28.5 min (18-49) for water, and significantly shorter for water followed by sham feeding, 22.8 (14-40), P = 0.0078.

CONCLUSION

Broth empties faster from the stomach than plain water, probably because of a "cephalic phase" stimulation of gastric motility via the vagus nerve.

摘要

目的

研究肉汤和水的排空时间，并探讨头期对胃排空影响的可能性。

材料与方法

12名健康志愿者在不同日期分别进食350毫升水或350毫升肉汤。随后，10名志愿者单独饮水，并在饮水后假饲肉汤。在进食前通过超声检查测量胃窦面积5次作为基线值，并在进食后每隔1 - 4分钟测量一次。确定胃窦面积减小至基线值150%时所用的时间（T150），并将其作为胃排空时间的替代指标。

结果

水的平均T150为20.3分钟（范围12 - 40分钟），肉汤的平均T150显著短于水，为12.6分钟（5 - 21分钟），P = 0.0020。在后续实验中，水的平均T150为28.5分钟（18 - 49分钟），饮水后假饲肉汤时水的平均T150显著缩短，为22.8分钟（14 - 40分钟），P = 0.0078。
