To evaluate how the sex and bilitubin levels could induce abnormalities in latency wave I and V we studied the brainstem auditory evoked reponses in neonates with hyperbilirubinemia. We analysed 29 female neonates with total bilirubin levels of 17,88±4,29 mg/dl and 51 male neonates with total bilirubin levels of 18,87±4,62 mg/dl until 48 hours of life. Latence I-V were measured by BERA using monoaural 120 dB click stimuli in Amplied MK 15. Abnormal BERA was defined as latencies I-V > 5.5 ms. Statistical analysis was performed by Mann-Withney test:

  • Male - p values: (BT) - 0.321 / (P I - V) - 0.5745

  • Female - p values: (BT) - 0.321 / (P I - V) - 0.4668

We concluded that sex cannot be indicated as a risk factor of hyperbilirubinemia and prolongation of P I - V. Moreover, studies in males with neonatal hyperbilirubinemia accompanhied at 18 years of age should be observed minor handcap.
