An 8-month old female, fully-immunized, otherwise healthy is brought in by paramedics after 1 minute of witnessed generalized tonic-clonic shaking. The patient had otherwise been well, eating and behaving normally earlier that day. On EMS arrival, the patient was post-ictal but grew increasingly responsive en-route and upon presentation to the pediatric emergency department she was crying and appeared normal to her parents. Capillary glucose was 118g/dL. On examination the patient was noted to be febrile with a rectal temperature of 39.4°C. The remainder of the physical examination was normal.
The patient received anti-pyretics and a urinalysis was obtained which was not suggestive of urinary tract infection. During the 3-hour period of observation in the emergency department the patient remained at her normal baseline, had no further seizure activity, and tolerated oral intake with difficulty. The patient was suspected to have a simple febrile seizure and was discharged home.
