Nasal rather than rectal benzodiazepines in the management of acute childhood seizures?

Benzodiazepines are routinely used by the rectal route for the treatment of acute epileptic seizures: if a benzodiazepine was absorbed from nasal administration this could provide a more acceptable alternative to rectal administration. Nineteen children (age range 7 months to 14 years) with intractable epilepsy were chosen. The EEG's showed unequivocal epileptic activity persisting during the recording. The midazolam was dripped slowly into the anterior nares. Fifteen had a positive response, a dramatic improvement in their EEG or cessation of fits. Drug induced beta activity occurred in 14 children. The mean time to appearance of beta activity was 111.5 secs (SD = 95.3 secs). The reduction in spike count pre and post midazolam was statistically significant (p < 0.01). The improvement in EEG background was also statistically significant. Midazolam is absorbed via the i.n. route. With the dosages used it suppressed epileptic activity and produced an improvement in EEG background. The children and parents found the method acceptable. This is the first study to use the i.n. route for anti-convulsant drugs.
