The value of BAEF in early diagnosis of acute bilirubin encephalopathy in newborn / 实用医学杂志

ABSTRACT

Objective Acute bilirubin encephalopathy in neonates is the most serious complication of neonatal hyperbilirubinemia, is one of the main causes of neonatal death and disability. Clinical early diagnosis, early treatment can improve the prognosis in children. Methods Brainstem auditory evoked potential (BAEF) was detected on two patients (40 patients with ABE, 40 cases of normal controls, all full-term) in the state of sleep in children and analysis the difference between the two groups ,all testing was completed by experienced Department of ENT full-time technician in charge,SPSS15.0 statistical analysis software was took for data analysis (using rank sum test method). Results There was significant difference between the two groups of neonatal latency of wave I, latency of waveⅤ, interpeak time , acute bilirubinⅠ-Ⅴencephalopathy group was significantly longer than that of the control group. Conclusions The BAEF detection is the sensitive index of brainstem damage , can objectively and sensitively reflect the function of the central nervous system , can reflect the functional status of cochlear and brainstem structures , often brainstem was slightly damaged but no clinical symptoms and signs , BAEP has changed significantly , so the conventional BAEP examination performed on patients with hyperbilirubinemia help to find bilirubin brain damage as early as possible,and prevent the occurrence of bilirubin encephalopathy.
