Abstract

Specialized hearing tests for pets are currently in demand. A brainstem auditory evoked response (BAER) test is an objective, non-invasive, and practical electrophysiological method that records electric signals from the peripheral auditory system to the brainstem when an auditory stimulation is provided. In veterinary medicine, sedation or anesthesia is essential for a successful examination. In human medicine, research has established the indications for various sedatives, anesthetics, and drugs according to the depth of anesthesia required. However, in veterinary medicine, there are very few comparative studies on propofol or isoflurane, which are the most common anesthetics used. Therefore, the present study aimed to analyze the difference in BAER test results between sedation with medetomidine, anesthesia using propofol, and inhalation anesthesia with isoflurane after propofol administration. The test was conducted on four healthy adult dogs. There was no statistically significant difference in latency, interpeak latency, or amplitude between the various drugs. The results suggest that a sedative or anesthetic for the administration of a BAER test can be selected according to the patient's needs.
