title: Sequential use of standard and ambulatory EEG in neonatal seizures.
abstract: Adequate predictors do not exist to indicate whether seizures are likely to continue beyond the neonatal period. Thirteen neonates with seizures occurring after 7 days of age were evaluated with standard short-term electroencephalography (SEEG) during the initial seizures and with ambulatory EEG (AEEG) when each infant was within 37-44 weeks corrected age (i.e., gestational age plus chronologic age). Eight of 13 SEEGs, 10 of 13 AEEGs, and 12 of 13 with the combined use of both SEEGs and AEEGs accurately predicted the occurrence of seizures at 3-4 months corrected age. Results with SEEG and AEEG did not produce significantly different outcomes. Combined analysis of SEEG and AEEG produced significantly different results from those calculated when the two EEG types were analyzed independently (Z = 3.98, p less than 0.001). The findings indicate that the use of both of these tests may improve the ability to predict continued seizure activity in infants with neonatal seizures when compared to the use of each measure separately.
