Midazolam in neonatal seizures with no response to phenobarbital

Abstract

The outcome of 45 neonates with EEG-confirmed seizures (ESz) was analyzed with regard to treatment. ESz persisted in 17 of 32 neonates receiving phenobarbital/phenytoin (13 had a poor outcome, 4 died). In contrast, ESz were rapidly controlled in 13 of 13 nonresponders to phenobarbital/phenytoin treated with midazolam (4 had poor outcome, 2 died). Nonresponders to phenobarbital/phenytoin had a significantly worse outcome than responders did. Midazolam effectively controlled ESz in nonresponders to phenobarbital/phenytoin and correlated with significantly improved long-term neurodevelopment.
