Abstract: Objective To investigate the relationship with neonatal hyperbilirubinemia between total bilirubin / albumin ratio(B/A)with brain magnetic resonance imaging (MRI) abnormalities and its clinical significance. Methods A total of 162 neonates hyperbilirubinemia (total serum bilirubin ≥342.2 μmol / L) between January 2013 and January 2014 enrolled in the study.They were divided into two groups,according to the Results of brain MRI:normal MRI group (n=126)and abnormal MRI group (n=36).Retrospective analysis of the relationship between B/A ratio of brain magnetic resonance imaging. Result The Results showed that the abnormal MRI group had a higher B/A ratio compared with the normal MRI group.it reached statistical significance (P<0.05). Conclusions High B/A ratio is a risk factor for abnormal MRI neonates with severe hyperbilirubinemia,which is the reason that could cause neurobehavioral sequelae of neonates.Primary hospital through observe B/A,high B/A ratiowith severe hyperbilirubinemia shoud active cut down jaundice,reduce neurobehavioral sequelae of neonates,enhance follow-up of high rise children.
