[The exploratory study of auto-auditory brainstem response in the high-risk infants on hearing screening].
OBJECTIVE
To compare the pass rate of auto-auditory brainstem response (AABR) in infants complicated with different high-risk factors.


METHODS
245 infants (488 ears) with different high-risk factors, including premature, low-weight, hyperbilirubinemia, asphyxiation and pulmonary diseases, were tested by transiently evoked otoacoustic emission (TEOAE) and AABR at the same time.


RESULTS
The pass rate of AABR and that of TEOAE were different for the infants with different high-risk factors. The number that passed TEOAE test and referred to AABR test: premature 15 ears, low-weight 3 ears, for hyperbilirubinemia 1 ears, for asphyxiation 5 ears, and for pulmonary diseases 35ears. The pass rate of AABR was reduced evidently when infants had pulmonary diseases and the complicated high-risk factors (chi(2) = 35.723, P < 0.01). Different high-risk factors produced different pass rates of AABR (chi(2) = 40.556, P < 0.01).


CONCLUSIONS
High-risk factors effect the auditory function. The pass rate of AABR is reduced evidently when an infant has both pulmonary diseases and the complicated high-risk factors. We should pay attention to these infants in universal newborn hearing screening.
