In the management of status epilepticus (SE), if first-line benzodiazepines fail after 20 minutes, which IV agent is recommended as second-line per current guidelines?

• A IV phenobarbitone as sole second-line option
• B IV lacosamide as the only guideline-approved second-line drug
• C Immediate intubation and propofol without trialling second-line drugs
• D IV levetiracetam, IV valproate, or IV fosphenytoin (all equivalent second-line options) ✓

Explanation

The ESETT trial (2019, NEJM) found that IV levetiracetam 4500 mg, IV valproate 40 mg/kg, and IV fosphenytoin 20 mg PE/kg are all equivalent in efficacy for benzodiazepine-refractory SE, with similar seizure cessation rates (~45% each). Current NCS and AAN guidelines list all three as acceptable second-line agents. Phenobarbitone is an alternative but not preferred in first-instance. Propofol/thiopental is reserved for refractory SE requiring anaesthesia.
