Value of long-term video electro-encephalography monitoring on diagnosis and prognosis of neonatal seizure / 中华实用儿科临床杂志

ABSTRACT

Objective To evaluate the efficiency of long-term video electro-encephalography(VEEG) monitoring in neonatal seizure.Methods The medical records of 36 neonates recruited and performed with long-term VEEG in the neonatal intensive care units in hospital from Jun.2011 to Jun.2012 were collected.The medical records included age,gender,diagnosis,VEEG background,epileptiform activity,epileptic seizures (electrographic seizures,electroclinical seizures or both),and nonepilepic events.Informations on prognosis and therapy was also obtained.Results Among the 36 neonates,the neonates with normal,or mildly,moderately,and severely abnormal VEEG were 3 (8.3％),9 (25.0％),16 (44.4％) and 8 (22.2％) neonates,respectively.Children with normal electro-encephalography (EEG) developed normally.The percentage with developmental delay in children with mildly,moderately,and severely abnormal EEG were 1 1.1％,37.5％ and 62.5％,respectively and abnormal VEEG was significantly associated with developmental delay(x2 =13.8,P =0.003).Among these 36 neonates,21 cases had neonatal seizures (58.3％),including 14 (66.7％) cases with epileptic seizures and 6(28.6％) cases with nonepileptic seizures and 1 case with both.In addition,13 (61.9％) cases out of 21 cases with neonatal seizures developed abnormally (including developmental delay and death),and there was no significant association between neonatal seizure and development (x2 =0.206,P =0.65).Conclusions Neonatal seizure is very common,but electroclinical dissociation is an outstanding feature of neonatal seizures.Long-term VEEG monitoring is a valuable tool and may aid in the early identification and management of patients who are more likely to develop epilepsy.
