Symptom narrative

To clarify: I do not know the brand name of the Flu shot the child received. He received his shots at the (withheld) and I am a hospitalist. The child has had temps to 101 after prior vaccines (he is up-to-date on vaccines). The only shot he had never received is Flu. Grandma usually pre-treats with Tylenol but she did not this time. He spiked a temp of 105 at home; 41 on arrival to the ED. He had GTC seizure at home for 1-2 minutes, then stopped for 5-6 minutes, then again for another 1-2 minutes. EMS did not give antipyretics before ED arrival. Had another seizure in the ED while on LTM monitor & temp was 39.1. Received Ativan at 11:14am. Diagnosis: complex febrile seizure. Received Keppra Load. Admitted to the hospital for LTM (EEG monitoring). Did well. No more seizures. EEG normal other than during the seizure. No viral symptoms. Resp viral panel negative. No identified source of infection so we do think the fever was from the vaccines. He went home the next day on Keppra & Diastat prn, to f/u with neuro. He was in good condition. No long-term effects expected.
