Rationale: Benign epilepsy with centrotemporal spikes (BECTS) is one of the most common forms of childhood epilepsy, which is expected to resolve before 16 years of age, with mild effects on the cognitive or behavioral functions in adulthood. This study aims to report the first propofol-induced refractory status epilepticus (SE) in patients with BECTS after 16 years of age, and to review SE in BECTS or induced by propofol.
Patient concern: A 16-year-old Chinese girl, who was diagnosed with BECTS at the age of 2 years, developed refractory SE induced by propofol administered during the maintenance stage of general anesthesia during a plastic surgery procedure.
Diagnoses: Considering her medical history, EEG, and magnetic resonance images, and brain computed tomography, a diagnosis of refractory SE in BECTS was confirmed.
Interventions: The patient had been seizure-free for 3 years from treatment with 2 anti-epileptic drugs (AEDs) valproate acid (VPA) and oxcarbazepine (OXC), and had started monotherapy with OXC for 3 months before the seizure incidence. She had undergone blepharoplasty under local anesthesia prior to receiving general anesthesia. During the maintenance state she developed convulsive SE, which was uncontrolled seizure and lasted for 14 hours. The treatment for which included midazolam, diazepam, propofol, VPA, OXC, and levetiracetam (LEV).
Outcomes: The prolonged seizure was controlled by diazepam (4 mg/h), propofol (6 mg/kg/h), VPA (2400 mg/d intravenous injection). Subsequently, she was administered VPA (800 mg/d po), OXC (600 mg/d po), and LEV (1000 mg/d po). Finally, on the 17th day she was discharged, and did not have any seizure recurrence and EEG results were normal as noted during the 3-month follow-up.
Lessons: This was the first report of an SE in BECTS patient past the remission age. This report implied that interventions of sedation or analgesia in a patient after remission age of BECTS might still be at risk of refractory SE and therefore, should be carefully evaluated and monitored during such procedures, especially when an AED medication has been withdrawn or altered.
