From the Guidelines

Status epilepticus in a pediatric patient is a life-threatening medical emergency that requires immediate attention and treatment.

Status epilepticus is defined as a seizure that lasts more than 30 minutes or two or more seizures between which the patient does not fully recover [not explicitly stated in the provided evidence, but based on general medical knowledge].
The International League Against Epilepsy (ILAE) classifies seizures as focal onset, generalized onset, or unknown onset 1.

In children, seizures represent a heterogeneous group of medical conditions, ranging from benign cases to life-threatening situations such as status epilepticus 1.
The underlying cause of seizures in children may range from idiopathic cases to a wide variety of acute and chronic intracranial or systemic abnormalities 1.
Neuroimaging tests, such as EEG and imaging studies, are essential in evaluating the underlying cause of seizures in children and guiding clinical decision-making 1.

The management of status epilepticus in pediatric patients involves prompt recognition, stabilization, and treatment with antiepileptic medications, such as benzodiazepines, followed by second-line agents like phenytoin or valproate [not explicitly stated in the provided evidence, but based on general medical knowledge].
The goal of treatment is to stop the seizure activity as quickly as possible and prevent long-term neurological damage.
It is crucial to identify and address the underlying cause of the seizure to prevent future episodes and improve patient outcomes.

From the Research

Status epilepticus is characterized by a prolonged, self-sustaining seizure or repeated seizures without return to baseline 2
The clinical manifestations of status epilepticus in children range from overt generalized convulsions to more subtle behavioral manifestations, including unresponsiveness in the setting of the intensive care unit 2
Status epilepticus is the most common neurologic emergency of childhood, with a large proportion of episodes resulting from a prolonged febrile seizure or an acute symptomatic etiology 2

Treatment of status epilepticus should commence promptly upon its recognition, using predefined treatment protocols 2, 3
The goal of treatment is the rapid termination of the seizure, to minimize the acute and chronic effects of this emergency and to allow for the prompt assessment and management of the underlying precipitant 2
The drug class of first choice in the in-hospital and out-of-hospital treatment of status epilepticus is the benzodiazepines, which may need to be quickly followed by a next-line agent 2
Next-line agents have traditionally included phenobarbital and phenytoin, but emerging evidence supports the use of intravenous formulations of other antiepileptic drugs 2
If the first two agents fail, high-dose intravenous midazolam or anesthetic therapy should be rapidly initiated 2

Status epilepticus is associated with high rates of morbidity and mortality, and early diagnosis and proper treatment are crucial 4
The mortality rate for pediatric patients with status epilepticus can range from 3.8% to 10% 4, 5
Patients with symptomatic etiology have greater odds of having cognitive and behavioral problems compared with patients with unknown etiology 5
Developmental delays, epilepsy, hemiparesis, spastic tetraparesis, and mental retardation are potential long-term complications of status epilepticus in pediatric patients 4, 5
