ABSTRACT
OBJECTIVE@#To discuss the characteristics of auditory brainstem response in preterm very low birth weight (VLBW) babies and to investigate the correlations between the ABR and clinical characteristics.@*METHOD@#Fifty-nine VLBW babies (118 ears) were enrolled in the study and 30 term normal babies as the control group. Tympanometry, acoustic reflex, DPOAE, ABR were obtained in all the babies.@*RESULT@#The prevalence of hearing loss in VLBW babies was higher than normal term babies and babies with perinatal complications higher than those without perinatal complications. There was no correlations between ABR threshold and gestational age, birth weight, postconceptional age, negative correlations between wave I, III and V latencies I - III, III - V and I - V intervals and postconceptional age. Wave I and V latencies, I - III and III - V intervals differed significantly between the two groups.@*CONCLUSION@#The perinatal complications were the most important causes of the hearing loss in preterm VLBW babies than the gestational age and birth weight. There was a high prevalence of peripheral hearing loss in the preterm VLBW babies. Combining OAE and automated ABR should be applied for hearing screening. Regular follow-up was very important in all the preterm VLBW neonatal.
