PURPOSE: To obtain the normality standard of the lower esophageal sphincter (LES) of cats anesthetized with tiopental and at analysing the practical viability of the anesthetic use in felines esophagus motor activity investigation. METHODS: Manometric studies of LES were performed in 12 cats anestetized with tiopental with perfusion reading in three radial channels. LES pressures and lengths were measured. RESULTS: The mean values of LES pressure and lengths were 33,52 ± 12,42 mmHg and 1,6 ± 0,4 cm respectively. CONCLUSION: A LES reference value for felines pressure and length was determined. Acommodation and return were comfortable for the animals with the use of sodic tiopental as an anesthetic agent.
