Abstract
Assessment of brain function is important in predicting long term outcome in sick neonates thus stimulating increasing interest in methods of cerebral surveillance. A report using the Cerebro Trac 2500 in adult intensive care suggested this monitor may provide more information about ongoing cerebral activity than the Cerebral Function Monitor (CFM). Simultaneous recordings in a cross-section of the neonatal population were obtained with multichannel EEG monitor, CFM and Cerebro Trac. Both conventional EEG and CFM determined changes in sleep states and background activity. Seizures of greater than 30 seconds duration were detected by both analyzing monitors, although shorter duration transients were not apparent. Despite the apparent similarity in fixed filters in both CFM and Cerebro Trac, the Cerebro Trac seemed to filter out the lower frequencies that can predominate in the neonatal EEG. The Cerebro Trac did not confer any advantage over the CFM for neonatal cerebral surveillance.
