Neonatal seizures associated with narcotic withdrawal

Area of Science:

• Neonatal Abstinence Syndrome
• Pediatric Neurology

Background:

• Neonatal narcotic addiction can lead to withdrawal symptoms, including seizures.
• Maternal drug use during pregnancy poses risks to newborns.

Purpose of the Study:

• To investigate the incidence of seizures in neonates with narcotic withdrawal.
• To compare seizure risk associated with different maternal narcotic exposures (methadone vs. heroin).
• To evaluate the efficacy of paregoric and diazepam in managing neonatal withdrawal seizures.

Main Methods:

• Retrospective analysis of 302 neonates passively addicted to narcotics.
• Categorization of infants based on maternal exposure to methadone or heroin.
• Clinical observation of seizure manifestations and response to anticonvulsant therapy (paregoric and diazepam).
• Electroencephalogram (EEG) recordings during interictal periods and seizure events.

Main Results:

• Eighteen out of 302 neonates experienced seizures attributed to withdrawal.
• Infants exposed to methadone had a significantly higher seizure incidence (7.8%) than those exposed to heroin (1.2%).
• Generalized motor seizures and myoclonic jerks were the primary seizure types.
• Paregoric demonstrated greater efficacy than diazepam in controlling and preventing seizures.
• Most interictal EEGs were normal; however, three infants showed paroxysmal brain wave activity during seizures.

Conclusions:

• Methadone exposure is associated with a higher risk of seizures in neonates undergoing withdrawal compared to heroin.
• Paregoric appears to be a more effective treatment for neonatal withdrawal seizures than diazepam.
• Further research is warranted to understand the neurophysiological mechanisms underlying these seizures.
