Management
All our patients required mechanical ventilation because of consciousness impairment. Median duration of mechanical ventilation was 3 days (lower and upper quartiles, 2-4 days), ranging from 1 to 7 days. Only 2 patients needed vasopressor support. Phenobarbital was the only anticonvulsant used. All our patients received dexamethasone during a median of 3 days (lower and upper quartiles, 2-5 days). Cefotaxime (300 mg/kg/d) and acyclovir (15 mg/kg every 8 hours) were administrated during a median of 3 days (lower and upper quartiles, 2-4 days).
