Refractory convulsive status epilepticus — FFICM MCQ

Correct answer: D — Induce anaesthesia with tracheal intubation and EEG-guided seizure suppression

The correct answer is D, induce anaesthesia with tracheal intubation and EEG-guided seizure suppression. This patient has refractory convulsive status epilepticus, defined as ongoing seizures despite an adequate first-line benzodiazepine and two appropriate second-line antiepileptic doses (here, levetiracetam). Current UK guidance from the Intensive Care Society mandates escalation to third-line therapy at this point, which means rapid sequence induction of general anaesthesia with airway control and titration against continuous or repeated EEG to confirm seizure suppression, since ongoing electrographic seizure activity can persist despite cessation of visible convulsions. The presence of hypoxia, acidosis and rhabdomyolysis reflects the systemic toxicity of prolonged status and reinforces the urgency of definitive control rather than further pharmacological escalation with agents already proven ineffective. Anaesthesia with agents such as thiopentone, propofol or midazolam infusion, alongside ICU admission, is the standard of care for this stage. Why the other options are wrong: E. Repeat benzodiazepines indefinitely: benzodiazepines are first-line only; repeated dosing beyond the initial treatment adds respiratory depression and hypotension risk without addressing refractory seizure activity that has already failed this class. B. Wait for serum levetiracetam level: status epilepticus is a time-critical emergency; delaying escalation to await a drug level ignores the clinical definition of refractoriness and risks further neuronal injury and worsening systemic complications. A. Give oral sodium valproate and observe: the oral route is inappropriate in an actively convulsing, unprotected airway patient, and valproate is a second-line intravenous option, not a rescue for established refractory status. C. Discharge after post-ictal recovery: the patient is not in a post-ictal phase, he is in ongoing refractory status with hypoxia and acidosis, making discharge dangerous and clinically inappropriate. Key point: failure of two appropriate second-line antiepileptic doses defines refractory convulsive status epilepticus, mandating general anaesthesia with airway protection and EEG-guided titration, not further drug escalation or delay.
