Topic:Sevoflurane
Sevoflurane is an inhalant anesthetic agent used in veterinary medicine, including equine practice, for the induction and maintenance of general anesthesia. It is characterized by its rapid onset and recovery times, which can be advantageous in managing equine patients. Sevoflurane is administered through a vaporizer and inhaled by the horse, allowing for precise control over anesthetic depth. Its effects on cardiovascular and respiratory systems are important considerations in its use, as is its interaction with other anesthetic drugs. This page compiles peer-reviewed research studies and scholarly articles that investigate the pharmacokinetics, safety, and clinical applications of sevoflurane in horses, providing insights into its use in equine anesthesia.
Recovery from sevoflurane anesthesia in horses: comparison to isoflurane and effect of postmedication with xylazine. To compare recovery from sevoflurane or isoflurane anesthesia in horses. Methods: Prospective, randomized cross-over design. Methods: Nine Arabian horses (3 mares, 3 geldings, and 3 stallions) weighing 318 to 409 kg, 4 to 20 years old. Methods: Horses were anesthetized on three occasions with xylazine (1.1 mg/kg), Diazepam (0.03 mg/kg intravenously [i.v.]), and ketamine (2.2 mg/kg i.v.). After intubation, they were maintained with isoflurane or sevoflurane for 90 minutes. On a third occasion, horses were maintained with sevoflurane and given xylazine (0.1 mg/kg i.v.) when the vaporizer was tur...
Determination of the minimum alveolar concentration (MAC) and physical response to sevoflurane inhalation in horses. 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 clinical...
Sevoflurane and oxygen anaesthesia following administration of atropine-xylazine-guaifenesin-thiopental in spontaneously breathing horses. The effects of sevoflurane-oxygen anaesthesia at a light-surgical depth on clinically important features were evaluated in spontaneously breathing horses that received atropine, xylazine, and guaifenesin-thiopental. Mean end-tidal concentrations of sevoflurane ranged from 1.6 to 2.3% during 90 min maintenance. Recovery from anaesthesia was extremely rapid and smooth. Heart rates did not significantly change after anaesthesia. Arrhythmia was not observed. Mean arterial pressure (mean +/- SD) ranged from 86 +/- 17 to 98 +/- 5 mmHg during anaesthesia. Minute ventilation was low due to decreased r...
