Rectal diazepam: a clinical and EEG study after a single dose in children

EEG monitoring was performed on a group of ten children, aged 3 days to 13 years, during admission to the Paediatric Clinic at the University of Bologna for seizures. Diazepam was injected by rectal route as an anticonvulsant, using a dose of 0.5-1 mg/kg in the first nine children, whereas an intravenous bolus was administered to the last child. The main aim of this study was to document the time taken for the drug to reach the brain and to modify the electrical activity. We observed significant EEG changes between 1 and 9.30 min and, in particular, the appearance of fast activity over one or both hemispheres after rectal diazepam. The EEG results confirm the clinical efficacy of rectal diazepam.
