[Use of injectable lorazepam in status epilepticus: a comparative study in French-speaking hospitals]

Injectable lorazepam (IL) is marketed in many countries but in France is only available within the framework of a compassionate use program for refractory status epilepticus. This study aims to evaluate the differences of pediatric use and status of IL in the hospitals of the Mother-Child French-speaking Network (Réseau mère-enfant de la francophonie, i.e., RMEF).

Inclusion criteria are: firstly, RMEF member; secondly, one site per town; thirdly, all the Assistance publique-Hôpitaux de Paris hospitals. After a phone-recruitment in each selected hospital, a survey was sent by e-mail. The data collected concerned the number of beds in the hospital, the official status of IL, its place in the therapeutic strategy, in hospital consumption in 2008 (in milligram) and the therapeutic alternatives.

Among the 18 hospitals selected, 17 were contacted and 12 (70%) replied. IL is not marketed in Tunisia and Lebanon. In Switzerland, Canada and Belgium, IL is marketed and used in all the polled hospitals (6.2 to 48.0mg per bed). In France, only the Robert Debré Hospital uses it (3.2mg per bed). In the countries where it is marketed, IL was firstly prescribed for the studied indication. In the other countries, injectable diazepam was the first line treatment (six out of eight hospitals).

France is the only country where IL is available though not marketed. The pharmacokinetic data favor use of IL instead of its principal therapeutic alternative (injectable diazepam) but no currently available evidence concludes that IL is superior to diazepam in the management of pediatric status epilepticus. The official indication of IL in France (last intention) is in contradiction with its use in the countries where it is marketed and with the data of the literature in favor of the first intention. This works presents the first evaluation on the use of IL in pediatric status epilepticus in the RMEF hospitals. It highlights the discrepancies in the management of status epilepticus in comparable pediatric hospitals.
