Effects of dexamethasone and surgical hypotension on the stomach of dogs: Clinical, endoscopic, and pathologic evaluations

Abstract

SUMMARY Effects of dexamethasone and surgical hypotension on the gastric mucosa of 15 dogs was evaluated by clinical, endoscopic, and pathologic studies. Dexamethasone produced acute reddening of the gastric mucosa with frank hemorrhage, digested blood, and possible gastric erosions, whereas dogs treated by surgical hypotension did not have marked changes in the gastric mucosa. Gastrointestinal disease observed in dogs with spontaneous spinal cord injury that were given dexamethasone and decompressive spinal surgery was not produced. The role of corticosteroids and surgical hypotension in the pathogenesis of gastric lesions and the potential for spinal cord injury to produce gastrointestinal disease is discussed.
