Abstract:
Objective To investigate the auditory brainstem response (ABR) of newborns in the neonatal intensive care unit (NICU) after hear screening failure.Methods To test ABR of 833 healthy newborns with no perinatal diseases at the clinic,and 425 newborns born in NICU who failed the hearing screening of monaural or both-ear from March 2014 to May 2015.Results 49.6% of children′s wave V response thresholds were ≥30 dB in the NICU group and 36.1% children′s wave V response thresholds were ≥30 dB in healthy group.The hearing abnormality rate of the NICU group was significantly higher than that of the healthy group(P<0.05);The average auditory thresholds healthy of the group[(19.76±6.59)dB] was significantly lower than those of the NICU group[(41.52±20.35)dB](P<0.05);both ear latency for waves Ⅰ,Ⅲ and Ⅴ and interpeak latency for waves Ⅰ-Ⅴ in healthy group were significantly shorter than those in NICU group (P<0.05).Conclusion The hearing loss extent of the NICU group is greater than that of the healthy group.The ABR abnormality reflects auditory pathway is abnormal.
