ABSTRACT
As the development of technology in Neonatal Intensive Care Unit,the neurology outcome of premature has become a critical issue for their future life quality.Early electroencephalogram (EEG) test is a noninvasive and convenient method to monitor brain function.Nowadays,EEG monitoring has been used to evaluate the maturity of background activity,to detect subclinical seizures and to predict future neurological outcomes.The guideline of American clinical neurophysiology society in 2011,and the guideline of French clinical neurophysiology society in 2015 have made recommendations for the indication,timing and duration of EEG monitoring.Interpret EEG needs both skill and experience,it is hard for clinicians to master the skill in a short time.Hence,despite the advantages of EEG monitoring,the application of EEG among premature is limited.The amplitude-integrated EEG and other quantitative EEG monitoring method have become the latest research hotspot for evaluation of preterm brain function.In order to improve the recognition of EEG in the area of preterm neurologic evaluation,now the latest researches are reviewed.
