Intraoperative electroencephalography predicts postoperative seizures in infants with congenital heart disease.

ABSTRACT:

Background

During the surgical repair of infants with congenital cardiac defects, there can be periods of decreased cerebral blood flow, particularly during deep hypothermic circulatory arrest. As a result, these infants are at increased risk for seizures and long-term neurodevelopmental difficulties.

Methods

Thirty-two infants with congenital heart disease had continuous video-electroencephalographic (EEG) monitoring pre-, intra-, and postoperatively for 48 hours after surgery.

Results

For patients requiring deep hypothermic circulatory arrest (n = 17) the EEG pattern for all patients became suppressed and eventually isoelectric below 25 °C. Two of the 32 infants had electrical seizures within the 48-hour monitoring period. Both required deep hypothermic circulatory
