Abstract
The hearing of 35 hyperactive or difficult young children was assessed by electric response audiometry under Phenergan sedation. In no case did the test fail completely, or have to be abandoned. Although the 35 children were untestable by conventional audiometric methods, a realistic threshold estimate was achieved in all cases using electric response audiometry, although the confidence was low in almost 10% of the cases. A six and one half hour waking record of the auditory evoked response amplitudes of three young adult volunteers with and without Phenergan revealed no specific depressant effect of the drug in the absence of sleep.
