Abstract

Objective - To qualitatively and quantitatively evaluate the characteristics of desflurane with regard to the induction of and recovery from anesthesia in cats. Animals - 6 cats. Procedure - Anesthesia was induced and maintained with desflurane in oxygen. Individual minimum alveolar concentration (MAC) values were determined-anesthesia was maintained at 1.25 X MAC for a total anesthesia time (including MAC determination) of 5 hours. Cats were allowed to recover from anesthesia. Induction and recovery periods were video recorded and later scored by use of a grading scale from 0 to 100 (100 being the best outcome). Timing of events was recorded. Results - The MAC of desflurane was 10.27 ± 1.06%, and mean dose was 5.6 ± 0.2 MAC-hours. Times to loss of coordination, recumbency, and endotracheal intubation were 1.3 ± 0.4, 2.3 ± 0.3, and 6.4 ± 1.1 minutes, respectively. Median score for quality of anesthetic induction was 93 (range, 91 to 94). Times to first movement, extubation, standing, and ability to jump and land with coordination were 2.8 ± 1.0, 3.8 ± 0.5, 14.3 ± 3.9, and 26.4 ± 5.1 minutes, respectively. Alveolar washout of desflurane was rapid. Median score for quality of anesthetic recovery was 94 (range, 86 to 96). Conclusions and Clinical Relevance - Desflurane was associated with rapid induction of and recovery from anesthesia in cats; assessors rated the overall quality of induction and recovery as excellent. Results appear to support the use of desflurane for induction and maintenance of anesthesia in healthy cats.
