title: Comparative audit of intravenous lorazepam and diazepam in the emergency treatment of convulsive status epilepticus in children.
abstract: There is little evidence on which to judge the optimal treatment for convulsive status epilepticus (CSE) in children. This study compares the effect of intravenous (iv) lorazepam with iv diazepam as the first line of treatment of CSE. We studied all children with prolonged seizures arriving in the Accident and Emergency (A&E) Department in two separate periods. In the first 6-month period iv diazepam was used as standard treatment, in the second 1-year period iv lorazepam was used. We measured latency to stopping of seizure and any adverse events. A successful treatment was defined as one in which the seizure clinically ceased within 15 minutes after siting the iv cannula, requiring no further treatment.Intravenous diazepam (0.32 mg kg (-1)) was used in 17 of 26 patients, whilst iv lorazepam (0.13 mg kg (-1)) was used in 31 of 59. There were no differences between the two groups regarding age, sex and seizure type.The seizure was successfully controlled 15 minutes after siting the iv cannula in 11 (65%) patients treated with diazepam (median time of 3 minutes) and in 20 (65%) patients treated with lorazepam (median time of 5 minutes). These preliminary results suggest that iv lorazepam may be as effective as iv diazepam.
