Insights
Phenobarbital is still the primary treatment for neonatal seizures, but newer drugs like levetiracetam show promise with fewer side effects. More research is needed to confirm the best treatment strategies for infant seizures.
Area of Science:
- Neonatal neurology
- Pediatric pharmacology
- Epileptology
Background:
- Neonatal seizures require effective and safe treatment strategies.
- Limited high-level evidence exists for optimal neonatal seizure management.
- Phenobarbital, a traditional first-line therapy, has potential neurotoxic effects.
Purpose of the Study:
- To review recent advancements in neonatal seizure treatment.
- To focus on literature published since 2013.
- To evaluate the efficacy and safety of current and emerging therapies for neonatal seizures and status epilepticus.
Main Methods:
- Systematic literature review focusing on neonatal seizure treatments.
- Inclusion of data on recurrent seizures due to limited status epilepticus data.
- Analysis of efficacy, safety, and medication selection trends in Neonatal Intensive Care Units (NICUs).
Main Results:
- Phenobarbital remains the first-line treatment despite concerns about neurotoxicity.
- Bumetanide is no longer favored due to lack of efficacy and increased risk of hearing loss.
- Levetiracetam and topiramate show potential efficacy with improved safety profiles, though data is limited.
Conclusions:
- Current evidence for neonatal seizure treatment is limited.
- Newer agents like levetiracetam may offer safer alternatives.
- Further research is crucial to establish evidence-based guidelines for neonatal seizure management.
Purpose Of Review:
The purpose of this review is to report recent advances in treatment of neonatal seizures, with a specific focus on new literature since a 2013 systematic review performed by this author (Slaughter) and others. There is a paucity of data with regard to well-defined status epilepticus (SE) in neonates, so treatment of recurrent seizures was also included in this inquiry. We aimed to summarize the efficacy and safety profiles of current therapeutic options as well as describe trends in medication selection in the neonatal intensive care unit (NICU) setting.
Recent Findings:
Phenobarbital remains first-line therapy in practice, though there is increasing evidence of its neurotoxicity and long-term sequelae. Bumetanide failed an open-label trial for efficacy, demonstrated an increased risk for hearing loss, and has since fallen out of favor for use in this population. New agents, such as levetiracetam and topiramate, still have very limited data but appear to be as efficacious as older medications, with more favorable side effect profiles. There are limited high-level evidence-based data to guide treatment of neonatal seizures. Emerging research focusing on drug mechanisms and safety profiles may provide additional information to guide decisions; however, further research is needed.
