Children presenting with convulsions (including status epilepticus) to a paediatric accident and emergency department: an audit of a treatment protocol.

All children who presented in a convulsion, including convulsive status epilepticus, to the accident and emergency department over a 12-month period and who required treatment, were reviewed retrospectively to identify the effectiveness and safety of a specific treatment protocol. This protocol recommends the initial use of one, or if necessary, two doses of rectal or intravenous diazepam (0.4 mg/kg) followed by the simultaneous administration of phenytoin (18 mg/kg) and rectal paraldehyde (0.4 mL/kg), with instructions for maximum doses and timings of administration. Eighty-one evaluable children (52 male) were audited. The mean age of the study population was 4.1 (range 0.1 to 14.9) years. Overall, the presenting convulsion was successfully terminated in 76 children (94%) within the accident and emergency department. In 69 children (85% of the entire study population) this was after a single dose of diazepam (rectal in 41 and intravenous in 28). In only an additional two children did the presenting convulsion stop after a second dose of diazepam. In five of the 10 children (50%) who received paraldehyde and phenytoin as a combination, the convulsion stopped. Nine patients (11%) required admission to the intensive-care unit, five because of persisting convulsive activity, and four because of respiratory depression. The results of this retrospective audit suggest that the current treatment protocol appears to be effective and relatively safe in treating acute convulsions, including convulsive status epilepticus. The audit is to be repeated prospectively to either confirm or refute these findings before recommending any changes to the protocol.
