ABSTRACT

Background. High levels of bilirubin may be neurotoxic; auditory system is highly sensible. Brainsteam auditory-evoked responses can detect early bilirubin toxicity. This study was made to compare associated factors to auditory damage among jaundiced newborn infants.
Patients and methods. It is a case –control study among 106 jaundiced newborns infants. It were reviewed clinical files to get demographic and clinical information, bilirubin level and brainsteam auditory– evoked responses.
Results. 54% had altered responses. It were more frequent among newborns with bilirubin level higher than 30 mg/dL (10.5 vs 0%, p ‹ 0.01); 89% of the cases had altered responses at lower level. It was any difference in gestational age, birth weight, peak bilirubin, percentage of haemolisis, males, hypernatremia, lost weight, clinical encefalopathy, feeding or associated pathologic couditions.
Conclusions. It’s not possible predict altered brainsteam auditory– evoked responses only with clinical manifestations or bilirubin level when it is below 30 mg/dL.
