Abstract:
Objective To investigate the diagnostic correlation and sensitivity of amplitude integrated electroencephalogram (aEEG),brainstem auditory evoked potential (BAEP) and cranial magnetic resonance imaging (MRI) for acute bilirubin encephalopathy (ABE) in the newborn.Method Term and near-term neonates (gestational age ≥ 35 weeks) with hyperbilirubinemia (the level of bilirubin over than 95th percentile) of high and intermediate risk group admitted in the neonatal ward of Guangxi Maternal and Child Health Care Hospital from Jan 2014 to Dec 2015 were recruited retrospectively.The infants were assigned to ABE group and non-ABE group according to the diagnostic criteria of ABE.The clinical data of the newborns were collected and the diagnostic correlation between clinical diagnosis and aEEG,BAEP and cranial MRI were analyzed.The receiver operating characteristic (ROC) curve was adopted to assess the diagnostic efficiency of the peak level of serum bilirubin,aEEG,BAEP and cranial MRI on the early diagnosis of ABE.Result A total of 152 newborns with hyperbilirubinemia were recruited,including 33 cases in the ABE group and 119 cases in non-ABE group.(1) The results of aEEG and MRI were marginally positively correlated with clinical diagnosis of ABE (aEEG:r =0.487,P ＜ 0.001;MRI:r =0.220,P=0.018),while the results of BAEP were closely related to the clinical diagnosis of ABE (r =0.593,P ＜ 0.001);(2) The results of BAEP and MRI on the diagnosis of ABE were positively correlated with those of aEEG (BAEP:r =0.424,P ＜ 0.001;MRI:r =0.307,P ＜ 0.001).(3) The area under the ROC curves for predicting the onset of ABE were 0.899 for the peak level of serum bilirubin,0.767 for BAEP,0.738 for aEEG and 0.590 for MRI.Conclusion There was the correlation on the diagnosis of ABE among the methods of aEEG,BAEP and MRI.The combined diagnosis of the three methods could play a complementary role.The aEEG contributed to the early diagnosis of ABE with high sensitivity.
