In piglets hypovolaemic shock causes motorical disturbances and gastroduodenal dysrhythmia which both lead to increased duodenogastric reflux and to elevated concentrations of lysolecithine in the stomach. During a long lasting and severe shock gastric movements and electrical control activity waves totally cease. These changes can be observed as well endoscopically as using myoelectrogrammes. Exposition of the gastric mucosa to duodenal juice together with ischemia causes intramucosal haemorrhages and superficial erosions resembling human stress ulcers.
