Objective: To compare the occurrence of hearing loss in neonates with hyperbilirubinemia, hypoxic-ischemic encephalopathy (HIE) and very low-birth weight infant (VLBW) body mass, and to provide evidence for early intervention.
Methods: Totally 299 high-risk neonates (598 ears) were divided into six groups: pure hyperbilirubinemia group, pure HIE group, hyperbilirubinemia with HIE group, hyperbilirubinemia with VLBW group, HIE with LBWI group, hyperbilirubinemia with VLBW and HIE mass group. Auditory brainstem response (ABR) was detected in all groups.
Results: The hearing threshold of ABR and the abnormal rate of hyperbilirubinemia with LBWI and HIE were much higher than that of pure hyperbilirubinemia and pure HIE neonates.
Conclusions: Of the three high-risk factors, hearing loss occurs more often and more serious in neonates with hyperbilirubinemia and with VLBW while as HIE body mass. So the babies should receive hearing screening with ABR and be treated in time or following up as early as possible.
