Brainstem electric audiometry: is routine sedation necessary?
Decreased EEG and EMG waves in sedated adults might produce more sensitive and better defined brainstem electric response. This was investigated by comparing the brainstem electric response to click stimulation in 10 adult volunteers before and during sedation with chloral hydrate. The results showed that there is no increase in sensitivity of the test in cooperative and relaxed adult subjects. The definition of wave I did not improve after sedation. It is therefore concluded that routine sedation is not advantageous in brainstem electric response audiometry in cooperative subjects.
