Auditory brainstem responses (ABR) in neonates with hyperbilirubinemia

Abstract

The technique of ABR testing was applied to 25 infants with neonatal hyperbilirubinemia at levels exceeding that for exchange transfusion, in an attempt to study potential influence of bilirubin toxicity on the auditory brainstem pathway. The test was performed at a mean conceptional age of 40.4 +/- 0.6 weeks just after discharge. Twenty normal term neonates of comparable birth weights and conceptional ages, who had no hyperbilirubinemia, were also examined for comparison. Fifty six percent (n = 14) of the hyperbilirubinemic neonates had some abnormality in the ABR pattern, the major one being a transient increase in the threshold of wave V (7, fail-30; 5, fail-45). Wave V, however, was consistently present at 30 dBnHL click stimulus in all the normal neonates (pass-30; normal threshold). Further, mean ABR latencies (wave III, V) and 1-V interpeak latency (brainstem conduction time) were significantly prolonged in jaundiced neonates as compared with controls (P less than 0.01). ABR changes were strongly correlated with the serum bilirubin levels (P less than 0.001). On follow up retesting at 3 months, however, all infants were found to have normal ABR latencies and threshold. Neonatal jaundice was associated with significant tr...Continue Reading
