Rectal benzodiazepines for premedication in children. Review and personal experience.
Modern anesthetic techniques have modified the aims of premedication in pediatric practice. Anxiolysis, amnesia and easiness of induction are now the the main targets. This paper reviews both the literature and the personal experience of the authors on the subject. Many authors now prefer a benzodiazepine. Rectal instillation of benzodiazepine in solution avoids the trauma of the intramuscular route and produces a faster and more predictable effect, than suppositories. Diazepam (.1 to .2 mg/kg) and flunitrazepam (40 to 80 micrograms/kg) have been extensively used in this indication. Diazepam's duration of elimination being much longer than that of flunitrazepam, this last drug is preferred by many pediatric anesthetists. Midazolam (.4 to .5 mg/kg) has a much faster onset and shorter duration of action. It should thus be preferred if the environment enables the administration of premedication within 10 to 15 minutes of induction.
