Cerebral function monitor in the neonate. II: Birth asphyxia

The cerebral function monitor (CFM) records an integrated electroencephalogram on slow-running paper, and therefore is suited to long-term, continuous monitoring. This study describes CFM patterns of 31 neonates with birth asphyxia. Three distinct types emerged: (1) a normal pattern compatible with gestational age was uniformly associated with favorable clinical outcome; (2) a completely disorganized pattern was associated with sever injury and fatal outcome; and (3) a more subtle pattern showed reversal to a more immature gestational age. The three infants with the third pattern all survived, but with varying degrees of neurological deficit. It is concluded that the CFM can be of advantage in predicting outcome for asphyxiated neonates.
