Nasotracheal intubation is an indispensable procedure in the anesthetic management of children with congenital heart defects that undergo surgical procedures. This technique allows to maintain and to protect the airways and facilitates reliable ventilation. The intubation technique in pediatric patients requires deep muscle relaxation in a short period of time, with minimum hemodynamic impact. Though intubation can be performed shortly after the administration of succinylcholine, this drug is associated to a number of side effects, some of them are totally unacceptable in high risk patients. Nondepolarizing muscle relaxants regularly available delay a lot and are not used for tracheal intubation in many hospitals. Introduction of a new nondepolarizing relaxant with starting of action in short time and minimum hemodynamic effects solves many of our difficulties. A study was made on the conditions for tracheal intubation in a group of cardiac children after the administration of rocuronium at average dose of 0,6 mg per kg of body weight. The average time needed for an adequate muscle relaxation ranged from 60 to 90 seconds and later additional dose after 30 minutes as an average to keep the anesthetic effect. Neither hemodynamic effects nor accompanying complications were attributed to the use of this muscle relaxant.
