Association Between Prophylactic Anti-Seizure Medication and Early Post-Traumatic Seizures: An International...

Area of Science:

• Neurology
• Pediatric Critical Care
• Clinical Pharmacology

Background:

• Early post-traumatic seizures (EPTS) are a concern in pediatric traumatic brain injury (TBI).
• The efficacy of prophylactic anti-seizure medication (ASM) in preventing EPTS after TBI is not well-established.
• Understanding EPTS prevalence and risk factors in children with TBI is crucial for guiding treatment strategies.

Purpose of the Study:

• To determine the prevalence of EPTS in pediatric TBI patients.
• To compare clinical characteristics between children with and without EPTS.
• To investigate the association between prophylactic ASM use and the occurrence of EPTS in pediatric TBI.

Main Methods:

• An observational study was conducted across 28 pediatric intensive care units in 15 countries.
• Data were collected from January 2014 to October 2022, involving 697 children with TBI.
• Logistic regression analysis was used to assess the relationship between prophylactic ASM and EPTS, controlling for relevant factors.

Main Results:

• The overall incidence of EPTS was 23.1% (161/697) among children with TBI.
• Prophylactic ASM was administered to 40.2% (280/697) of the patients.
• ASM use was significantly associated with a reduced likelihood of EPTS (9.6% vs. 32.1%, p < 0.001).
• Younger age (≤ 4 years) and lower Glasgow Coma Scale scores (≤ 8) were risk factors for EPTS.
• Phenytoin, levetiracetam, and phenobarbital were the most common prophylactic ASMs.

Conclusions:

• Prophylactic ASM use demonstrated a potential protective role against EPTS in pediatric TBI.
• The findings support the consideration of prophylactic ASM in managing children with TBI.
• Further research may refine guidelines for ASM use in this population.
