The value of amplitude integrated electroencephalographic monitoring in early neonatal brain injury and prediction prognosis of asphyxia neonatal

Abstract

Objective To discuss the value of amplitude integrated electroencephalographic (aEEG) monitoring in early neonatal brain injury and prognosis of asphyxia neonatal. Methods Seventy-two subjects of asphyxia children were divided into mild asphyxia group and severe asphyxia group. We selected 45 cases of full-term healthy children born in our hospital as control group in the same term. All the objects were observed by aEEG monitoring within 6 hours. According to the aEEG results, all the samples were redivided into normal aEEG group, mildly abnormal aEEG group and severely abnormal aEEG group. All subjects were followed-up to observe their physical growth and the nervous system development at one-year-old. Results Incidence of abnormal aEEG in mild asphyxia group and severe asphyxia group was significantly higher than that of control group (χ2=26.996, 47.07, P 0.05), all of their mental index and developmental quotient were lower in severely abnormal aEEG group (χ2=13.450, 15.285, P<0.01, respectively). Conclusion aEEG can be used to assess the early neonatal brain injury of asphyxia neonatal, and it can be used to predict the prognosis of neonatal asphyxia based on the abnormal degree of aEEG.
