Neonatal seizure burden and status epilepticus

Criteria & assessment

• Clinical burden may be reported as seizure count per hour or total seizure duration divided by the duration of the epoch of interest.
• Research temporal-spatial burden sums seizure duration per hour in five non-overlapping neonatal montage regions so each electrode is counted once; the source lists Fp3-T3, C3-O1, Fp4-T4, C4-O2, Fz-Pz or an alternate pairing.
• Status epilepticus is present when summed seizure duration is >=50% of any defined 60-minute epoch.
