Summary
Auditory brainstem response testing is necessary in children who are not able to be tested by
classical audiogram, because of their age or an associated retarded psycho-motor development
or behavioral and cognitive troubles.
This test needs a perfect immobility of the child, ideally being asleep. This situation is
sometimes impossible to achieve in non-cooperative children.
Currently, in the Pediatric Hospital of Nice, the investigators have to do a general
anesthesia to perform quality auditory response tests in this kind of patients.
The alternative to a general anesthesia would be a reliable sedative drug, allowing the
performance of this diagnostic exam without the need of a hospitalization.
Dexmedetomidine is a sedative drug with an action on the α2 adrenergic receptors. It causes a
rapid sedation, similar to the natural sleep and with minimal secondary effects. The
possibility of an intranasal administration, avoids the pain and discomfort of a venous
access insertion.
