ObjectiveThe aim of this study was to evaluate the efficacy and safety of intramuscular midazolam in controlling convulsive status epilepticus in children, by comparing it with rectal diazepam.MethodsIn this randomized trial, 100 children (50 in each group) with convulsive status epilepticus aged 1 month to 16 years were enrolled and randomly assigned into two groups to receive either 0.3 mg/kg intramuscular midazolam or 0.5 mg/kg rectal diazepam. Main outcome measure was stopping of all motor activity after drug administration. Another measures were times between patient's arrival to emergency department till drug administration, between drug administration to seizure cessation, and between patient's arrival to seizure cessation.ResultsBoth medication were effective for seizure control and no significant difference was found between successful treatments after administering the medication (P = 0.061). In the midazolam group, in 96% (48/50) of cases treatment was successful and in the diazepam group, in 94% (47/50) of cases treatment was successful. Time from arrival to administering the medication was significantly shorter in midazolam group (P = 0.017). The majority of seizures in midazolam group were stopped in less than 66 s (median) compared to 130 s (median) for diazepam group, (P < 0.001). No serious adverse effects were seen in both groups.ConclusionIM midazolam is not superior but may be at least as effective as rectal diazepam for controlling of status epilepticus in children. Midazolam via IM route could be one of the choices in children with convulsive status seizures who have difficult IV access.Copyright © 2014 European Paediatric Neurology Society.
