What is the treatment for a 5-month-old boy experiencing convulsions in the right upper limb without fever?

From the Guidelines

For a 5-month-old boy experiencing right upper limb convulsions without fever, the most appropriate initial treatment is lorazepam 0.05 mg/kg (maximum 1 mg) intravenous (i.v.) to control electrographical seizures. This is based on the management guidelines for paediatric patients receiving chimeric antigen receptor t cell therapy, which although specific, provides a framework for acute seizure management in pediatric patients 1. The initial assessment should include checking circulation, airway, and breathing (CAB) and providing airway protection interventions, high-flow O2, and checking blood glucose level.

Key Considerations

• The dose of lorazepam can be repeated every 5 minutes (to a maximum of 4 doses) if seizures persist.
• Levetiracetam 40 mg/kg (maximum 2,500 mg) i.v. bolus can be added in addition to maintenance dose for ongoing seizure control.
• If seizures continue, transfer to a pediatric intensive-care unit (PICU) and consider adding phenobarbital i.v. at a loading dose of 10–20 mg/kg (maximum 1,000 mg) 1.
• Maintenance doses of anticonvulsant drugs after resolution of status epilepticus should be considered, including lorazepam, levetiracetam, and phenobarbital, with specific dosing guidelines provided in the management algorithm.

Further Evaluation

After stabilization, the child should undergo urgent evaluation with neuroimaging (MRI preferred) and an EEG to determine the underlying cause of the seizures, which could include structural brain abnormalities, metabolic disorders, or early-onset epilepsy syndromes. Laboratory tests including glucose, electrolytes, calcium, and magnesium should also be checked to rule out metabolic causes.

Long-term Management

Long-term management may include maintenance antiepileptic drugs, depending on the diagnosis, with the goal of preventing future seizures and minimizing developmental complications. The choice of antiepileptic drug will depend on the specific diagnosis and the child's response to initial treatment. Given the potential for serious underlying conditions, comprehensive neurological evaluation and close follow-up are crucial.

From the Research

Treatment for Convulsions in a 5-Month-Old Boy

• The treatment for convulsions in a 5-month-old boy with no fever involves the use of antiepileptic drugs (AEDs) 2.
• The established first-line treatment consists of benzodiazepines, most frequently intravenous lorazepam, which can be administered intravenously, intranasally, or intramuscularly 2.
• Other benzodiazepines, such as midazolam and diazepam, may also be effective as first-line treatments 3.
• If the initial treatment with benzodiazepines is not effective, treatment with fosphenytoin, phenobarbital, valproate, or levetiracetam may be recommended 2, 3.

Specific Treatment Options

• Midazolam has been shown to be a effective first-line treatment for convulsive status epilepticus in pediatric patients 3, 4.
• Phenobarbital has been shown to be effective in stopping seizures and preventing recurrence in pediatric patients with convulsive status epilepticus 3.
• Levetiracetam has been studied as a potential treatment for neonatal seizures, but its efficacy compared to phenobarbital is still being researched 5, 4.

Administration and Dosage

• The dosage and administration of AEDs, such as levetiracetam and midazolam, may vary depending on the patient's age, weight, and medical history 5, 4.
• The use of AEDs in pediatric patients requires careful consideration of the potential risks and benefits, as well as close monitoring for adverse effects 2, 3, 5, 4.
