Abstract: Objective To explore the correlated factors of bilirubin neurotoxicity. Methods From July 2007 to October 2007, 53 hospitalized patients with jaundice in neonatal ward of Peking University Third Hospital were enrolled in the study. The relationship between serum free bilirubin and parameters of brainstem auditory evoked potential(BAEP) was analyzed to screen the sensitive index of bilirubin neurotoxicity. Multivariate analysis was conducted between the sensitive parameter and various factors. Results Partial correlation analysis showed that the wave Ⅴ latency was positively correlated to serum free bilirubin(r=0. 228, P= 0. 020) after the corrected gestational age was controlled. There were no correlation between other latencies or interwave intervals and serum free bilirubin. Linear regression showed the equation was wave Ⅴ latency= 9.721-0. 082 × corrected gestational age+0. 064 × bilirubin/albumin+ 0. 504 × acidemia(F= 7. 534, P＜0.01). Conclusions Wave Ⅴ latency is the sensitive indicator of bilirubin neurotoxicity, which is correlated with the value of bilirubin/albumin and acidemia.
