Eclipse Support
An electrical auditory brainstem response (eABR) is a measurement of the ABR using an electrical stimulus. Instead of a traditional acoustic stimulus the cochlear implant (CI) or auditory brainstem implant (ABI) provides the stimulus that evokes the ABR.
eABR testing may be performed for the following reasons:
To verify adequate placement of the cochlear implant or auditory brainstem implant electrodes during surgery
To estimate thresholds and comfortable levels in infants, young children or other patients who cannot be assessed using behavioral techniques
To assist in mapping the cochlear implant or auditory brainstem implant device
To assess interactions between electrode channels
To determine the most appropriate rates of stimulation
Optimally, the patient should be lying down, asleep and in a quiet environment. Minimally, the patient should be relaxed with their eyes closed during testing. It is important to note that the eABR is not affected by anesthesia.
