Oral Diazepam in Febrile Seizures Following Acellular Pertussis Vaccination

Area of Science:

• Pediatrics
• Neurology
• Vaccinology

Background:

• Febrile seizures are common in children and cause parental anxiety regarding recurrence.
• Acellular pertussis vaccination is a common trigger for febrile seizures in susceptible children.

Purpose of the Study:

• To assess the efficacy of oral diazepam in preventing febrile seizure recurrence post-pertussis vaccination.
• To compare oral diazepam prophylaxis with standard care involving reactive rectal diazepam.

Main Methods:

• A clinical trial involving 121 children with a history of febrile seizures scheduled for pertussis vaccination.
• Children were randomized to receive either oral diazepam for 48 hours post-vaccination or standard care with reactive rectal diazepam for seizures.
• Incidence of fever and seizures, including febrile seizures, were compared between groups.

Main Results:

• Fever incidence was similar between oral diazepam (85.7%) and rectal diazepam (87.9%) groups.
• No children in the oral diazepam group experienced seizures after vaccination.
• Seven children (12.06%) in the rectal diazepam group had seizures post-vaccination, a statistically significant difference.

Conclusions:

• Prophylactic oral diazepam significantly prevents febrile seizure recurrence following acellular pertussis vaccination.
• Diazepam administration offers a protective strategy for children with a history of febrile seizures.
• Oral diazepam is a safe and effective preventive measure against post-vaccination seizures.
