Résumé

The auditory function of animal models has been observed to deteriorate with long-term anaesthesia. Whether the changes observed result from effects on central auditory pathways, or are caused by deterioration of the cochlear function is investigated. Adult chinchillas were anesthetized using a ketamine-xylazine combination. Auditory brainstem evoked responses (ABR) and middle latency responses (MLR) were monitored from the chinchilla during 12 hrs of anaesthesia, and the auditory function deterioration which resulted over this period is described.
