新生儿脑电图及其在新生儿惊厥诊断中的价值

正常新生儿脑电图包括睡眠结构、背景活动和阵发性活动三种类型.异常新生儿脑电图包括背景活动异常、阵发性异常、睡眠结构和成熟性异常.脑电图检查是确定新生儿惊厥发作不可缺少的诊断方法.新生儿惊厥发作的临床表现缺乏特征性,表现为不典型的、多变的、各种各样的发作形式.新生儿异常脑电图包括在正常背景活动上的局限性发作、限局性单一的周期性图形、多灶性发作异常伴有发作间期脑电异常活动和异常背景活动的限局性疴样发作等等.新生儿脑电图与脑的成熟度密切相关,脑电图的不同改变对新生儿预后的评价有指导意义.

Neonatal electroencephalography and its clinical value in the management of neonatal seizures

Sleeping cycle,background activities and paroxysmal activities were the most important indices in interpreting normal neonatal electroencephalography(EEG).Abnormal neonatal EEG included abnormal background activi-ties,paroxysmal activities,abnormal sleeping cycle and disordered maturation.Neonatal seizure may be very subtle clinically.They are often atypical,changeable with various presentations.Thus,EEG becomes a necessary diagnostic tool in the management of neonatal seizures.Focal paroxysmal discharge,focal unitary periodic activity.multifocal paroxysmal discharge with interictal abnormal activity or focal epileptic discharge with abnormal background activity were main patterns of abnormal neonatal EEG presentation.Neonatal EEG is closely related with the development of brain.Changes in EEG can predict the outcome of neonates.
