OBJECTIVES: To evaluate and describe brainstem auditory-evoked response measurements in healthy African pygmy hedgehogs (Atelerix albiventris).
MATERIALS AND METHODS: Brainstem auditory-evoked response measurements were performed in 12 adult African pygmy hedgehogs (seven males, five females) under general anaesthesia. Waveform morphology was assessed and wave latencies, amplitudes and interpeak latencies calculated.
RESULTS: Brainstem auditory-evoked response measurements were successfully performed in both ears from all hedgehogs. Three distinct waves were reproducible in all patients in both ears using a stimulus with an intensity of 90 dB nHL (decibel above normal hearing level). Amplitudes of waves I and V, latencies of waves I, II-III and V and interpeak latencies of waves I-V were calculated at 90 dB for both ears of each animal.
CLINICAL SIGNIFICANCE: This study describes normal brainstem auditory-evoked response morphology and latencies for African pygmy hedgehogs. General anaesthesia is required to perform this neurodiagnostic, given the unique behaviour and anatomy of hedgehogs. This baseline data may be useful for investigating hearing abnormalities and central nervous system disorders in hedgehogs.
