Insights
High-risk factors significantly impact infant hearing. Pulmonary diseases combined with other risk factors notably reduce the pass rate for auditory brainstem response (ABR) screening in newborns.
Area of Science:
- Neonatal audiology
- Pediatric audiology
- Hearing screening technologies
Context:
- Universal newborn hearing screening (UNHS) aims to identify infants with hearing loss early.
- High-risk factors are known to increase the likelihood of congenital hearing impairment.
- Evaluating the efficacy of different screening methods in high-risk infant populations is crucial.
Purpose:
- To compare the hearing screening pass rates of auto-auditory brainstem response (AABR) in infants with various high-risk factors.
- To determine the influence of specific risk factors, such as prematurity, low birth weight, hyperbilirubinemia, asphyxiation, and pulmonary diseases, on AABR and transiently evoked otoacoustic emission (TEOAE) test outcomes.
Summary:
- A study of 245 high-risk infants (488 ears) simultaneously assessed by TEOAE and AABR found varying pass rates based on risk factors.
- The AABR pass rate was significantly reduced in infants with pulmonary diseases, especially when combined with other risk factors (chi(2) = 35.723, P < 0.01).
- Overall, different high-risk factors demonstrated distinct impacts on AABR pass rates (chi(2) = 40.556, P < 0.01).
Impact:
- Findings highlight that high-risk factors significantly affect auditory function in newborns.
- Pulmonary diseases, in conjunction with other risk factors, markedly decrease AABR screening success.
- This underscores the need for targeted attention to infants with these combined risk factors during UNHS programs.
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).
Conclusion:
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.
