title: Determination of the minimum alveolar concentration (MAC) and physical response to sevoflurane inhalation in horses.
abstract: The minimum alveolar concentration (MAC) of sevoflurane required to prevent gross purposeful movement in response to electrical stimulation of the oral mucous membranes was determined in horses, and their physical responses to inhalation of this anesthetic were observed. The MAC was 2.31 +/- 0.11%. The horses showed good ventilation, without any signs of airway irritation such as coughing. The horses became slightly excited before they laid down. The end tidal sevoflurane concentration (ESC) required to produce recumbency was 2.54 +/- 0.11%. These results suggest that sevoflurane is a clinically useful anesthetic agent in horses.
