BackgroundSince clinical signs of meningeal irritation in infants may be absent or misleading, the American Academy of Pediatrics in 1996 recommended that a lumbar puncture be performed in young children following a febrile seizure. Recent evidence supports a conservative approach in children who do not look ill at the time of the physician's assessment. Moreover, seizures as the presenting or sole symptom of bacterial meningitis are very rare.ObjectivesTo assess physicians' compliance with the Academy's recommendations and to determine the incidence of meningitis among febrile seizure patients, including those who did not undergo the puncture.MethodsWe conducted a retrospective analysis of the number of punctures obtained in febrile seizure patients aged 6-24 months, focusing on the clinician's indications for performing the procedure and on the clinical course of children who did not undergo the puncture.ResultsAmong 278 patients (84% simple febrile seizure), 52 (18.7%) underwent the procedure. It was performed in 38% of 45 complex febrile seizure cases and in 48% of 91 infants younger than 12 months of age. Aseptic meningitis occurred in two infants, both with post-ictal apathy. Bacterial meningitis was not found and in none of the patients who did not undergo the puncture was meningitis later diagnosed.ConclusionsCompliance with the Academy's recommendations was low, as emergency room physicians based their decision whether to obtain a lumbar puncture solely on clinical grounds. No case of bacterial meningitis was detected among 278 young children with a febrile seizure, including those who did not undergo the puncture.
