The influence of phenobarbital overdose on aEEG recording.

Monitoring infants with amplitude integrated electroencephalography (aEEG) in neonatal units is becoming widespread. A case of a preterm infant who was monitored with aEEG due to suspected seizures is presented. The case emphasizes both the usefulness and drawback of aEEG. An erroneous diagnosis of seizure lead to phenobarbital overdose and the change of aEEG voltage and pattern assisted in a prompt diagnosis.
