Insights
Buccal midazolam effectively controls pediatric prolonged seizures, offering a safe first-line treatment. Intranasal lorazepam and intravenous valproate also show promise for seizure management.
Area of Science:
- Neurology
- Pediatric Emergency Medicine
Background:
- Prolonged seizures and status epilepticus in children are critical emergencies.
- Prompt intervention is vital for life support and seizure control.
Purpose of the Study:
- To systematically review the management of pediatric prolonged seizures and status epilepticus.
- To compare the efficacy and safety of various anticonvulsant medications.
Main Methods:
- Systematic review of published data on seizure management.
- Analysis of treatment effectiveness, seizure control rates, and recurrence rates.
Main Results:
- Buccal midazolam demonstrated higher efficacy (70% seizure control) than rectal diazepam.
- Intranasal lorazepam proved effective, comparable to intramuscular paraldehyde.
- Intravenous valproate showed faster seizure cessation and a safer profile than intravenous diazepam in refractory status epilepticus.
Conclusions:
- Buccal midazolam is a safe and effective first-line treatment for prolonged seizures due to its ease of administration.
- Intranasal lorazepam offers an effective, safe, and user-friendly option for prolonged seizures.
- Intravenous valproate is a favorable third-line option for refractory status epilepticus, demonstrating good efficacy and safety.
Abstract:
Pediatric prolonged seizures and status epilepticus are medical emergencies necessitating immediate life-support and seizure-control measures. A systematic review of published data on the management of prolonged seizures and status epilepticus showed that buccal midazolam was significantly more effective than rectal diazepam, reaching a seizure-control rate of 70% and recurrence rate of 8%. Intranasal lorazepam was as effective as intramuscular paraldehyde in a cost-restrained setting. In refractory status epilepticus, both intravenous midazolam and valproate were equally effective to intravenous diazepam, with valproate exhibiting significantly faster seizure cessation and safer profile than diazepam, even in infancy. In conclusion, buccal midazolam is efficacious and safe thanks to its convenient route of administration, which may serve as first-line in the treatment of prolonged seizures. Intranasal lorazepam is an effective, easy-to-use, and safe drug for prolonged seizures. Intravenous valproate exhibits favorable efficacy and safety profile as third-line in status epilepticus, refractory to diazepam and phenytoin.
