title: [Vecuronium bromide in pediatric anesthesia].
abstract: Ninety patients were included in a study to assess the clinical characteristics of vecuronium bromide used in children. The myorelaxant was administered to all patients using different routes. The use of vecuronium at a dose approximately equal to 1ED95 was characterised by a duration of action sufficient to allow its use in short operations; on the other hand, it also produced a long induction-intubation interval and not optimal conditions in which to perform intubation. Conditions for intubation improved during induction via inhalation and there was a reduced induction-intubation interval compared to intravenous induction using the same dose of vecuronium. A further reduction in intubation time was obtained by increasing the dose from 50 to 150 micrograms/kg-1 together with an increased clinical duration of action. The "priming principle" technique also allowed intubation time to be shortened without variations in the duration of action provided a full dose of vecuronium, 100 micrograms/kg-1, was used. However, this was also associated with a notable incidence of adverse reactions. Of the various combinations examined, the most advantageous association of pre-dose and interval between doses was the association of a pre-dose of 10 micrograms/kg-1 and an interval of 4 min between doses. Lower doses countered the advantages of priming, whereas higher doses resulted in an increased number of adverse reactions without producing notable changes in the intubation time.
