Seizures in neonates undergoing cardiac surgery underappreciated, dangerous

With mounting concerns about postoperative seizures, doctors placed 161 neonates who had undergone cardiac surgery on continuous EEG monitoring. They found that 8% of the neonates experienced EEG seizures and 85% of these were unrecognized clinically. Many of the seizures were severe, and the seizure group faced a higher risk of death, according to the investigators' report.
