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.

Primary | quality of diagnostic | measure the rate of children for who the auditory threshold is obtained with drug sedation condition. | 5 minutes after the realization of auditory test | |
Secondary | tolerance of treatment | The tolerance will measure by the collection of the following undesirable effects: hypotension, bradycardia: deviation of> 20% (systolic pressure for blood pressure) from the normal values defined for the age of the subject under waking conditions hypertension: deviation of> 20% (systolic pressure for blood pressure) from the normal values defined for the age of the subject in waking conditions decrease in oxygenation: decrease in oxygen saturation <90% These effects will determinate by cardiorespiratory monitoring during the examination. A routine home phone call on D1 will collect information about possible unexpected side effects. |
from drug administration to 24 hours after administration of drug | |
Secondary | time of correct sedation | measure of time in minutes between the administration of the drug and the obtaining of a correct sedation (4, 5 or 6 of the score of Ramsey). | from 5 minutes after drug administration to 5 minutes before auditory test | |
Secondary | time of vigilance recovery | measure the time between the end of the examination, (defined by the end of the recording and the disconnection of the electrodes) and the recovery of the vigilance of the child , evaluated by the Aldrete score . A score of 9 or more determines a correct recovery of alertness and the possibility of returning home. The child will be reevaluated every 10 minutes until this score is reached. | from 5 minutes after auditory test to 5 minutes after the patient wake up (Aldrete score equal to 9) |
