A 5-year-old child presents with a generalized tonic-clonic seizure lasting 20 minutes despite two doses of lorazepam IV. The next step per current PALS guidelines for refractory convulsive status epilepticus is:
- A Phenytoin 20 mg/kg IV
- B Levetiracetam 60 mg/kg IV
- C Either levetiracetam 60 mg/kg IV or valproate 40 mg/kg IV — both are equivalent second-line options ✓
- D Phenobarbital 20 mg/kg IV
Correct answer: C. Either levetiracetam 60 mg/kg IV or valproate 40 mg/kg IV — both are equivalent second-line options
Explanation
After two failed benzodiazepine doses (established status epilepticus), current evidence-based guidelines (ESETT trial) show that levetiracetam 60 mg/kg IV, valproate 40 mg/kg IV, and fosphenytoin 20 mg/kg PE IV are equally effective second-line options. Phenobarbital remains an alternative but carries more respiratory depression risk. The older practice of defaulting exclusively to phenytoin is no longer supported as superior.
