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

目的 探讨振幅整合脑电图（amplitude integrated electroencephalographic,aEEG）在窒息新生儿早期脑损伤及预后预测中的应用价值。方法 将72例窒息患儿分为轻度窒息组和重度窒息组,选择同期我院产科出生的健康足月儿45例为健康对照组。在生后6h内对所有观察对象进行aEEG监测,按aEEG结果把全部患儿分为正常aEEG组、轻度异常aEEG组、重度异常aEEG组,于1岁时,对研究对象与对照组同时进行生长发育及神经心理发育情况随访。结果 轻度窒息组、重度窒息组aEEG异常发生率明显高于正常对照组（X^2=26.996、47.07,P均＜0.01）,重度窒息组aEEG异常发生率明显高于轻度窒息组（X^2 =7.76,P ＜0.05）;全部患儿体格发育（身长和体重）比较差异无统计学意义（P＞0.05）;重度异常aEEG组患儿的头围偏小（X^2=8.734,P＜0.01;Spearman等级相关系数为0.62,P＜0.05）及智力指数、发育商偏低（X^2=13.450、15.285,P均＜0.01;Spearman等级相关系数为0.73、0.75,P均＜0.05）。结论 aEEG可用于窒息新生儿早期脑损伤的脑功能评价,通过aEEG异常程度可预测窒息新生儿预后。

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（X^2 =26.996,47.07,P 〈 0.01,respectively）,and incidence of abnormal aEEG in severe asphyxia group was significantly higher than that of mild asphyxia group （X^2 =7.76,P 〈 0.05）.There was no significant difference in all subjects about physical development （height and weight） （P 〉 0.05）,all of their mental index and developmental quotient were lower in severely abnormal aEEG group （X^2=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.
