Status epilepticus in children and adults

Area of Science:

• Neurology
• Emergency Medicine

Background:

• Status epilepticus (SE) is a prolonged seizure event, lasting over 30 minutes or multiple seizures without consciousness recovery.
• SE presents as convulsive (focal or generalized) or nonconvulsive (absence or partial complex) forms.
• Convulsive SE is a life-threatening emergency with a 10% mortality rate.

Purpose of the Study:

• To outline the critical management strategies for status epilepticus.
• To detail the sequence of anticonvulsant therapies for SE.

Main Methods:

• Initial management prioritizes life support and vital function maintenance.
• Pharmacological treatment typically begins with intravenous lorazepam, a benzodiazepine with a longer duration of action and less respiratory depression than diazepam.
• Sustained seizure control often requires concurrent intravenous phenytoin loading.

Main Results:

• Lorazepam is increasingly preferred over diazepam for initial SE treatment.
• Phenytoin is commonly used in conjunction with lorazepam for effective seizure management.
• Phenobarbital may be administered if seizures persist or recur despite initial treatments.

Conclusions:

• Prompt and aggressive management is crucial for improving outcomes in status epilepticus.
• A stepwise approach involving benzodiazepines, phenytoin, and potentially barbiturates is effective.
• Refractory cases may necessitate advanced interventions like barbiturate coma or general anesthesia.
