The thresholds of the auditory brainstem response, the latencies of different waves, the V/I ratio, and the changes of the latencies of wave I and wave V induced by the modified, repeated click stimulations in 44 cases (88 ears) of asphyxial neonates were studied. Significant differences were noted as compared with the controls, suggesting that the function of the auditory passage of the asphyxial neonates was impaired. When the function was re- examined after the age of 1 years, the impairment remained progressive which could influence the development of the language and intelligence of neonates. It is important to make an early diagnosis for auditory rehabilitation without delay.
