Intubation Time With Low Dose Rocuronium

Study of Intubation Time Required for Excellent Tracheal Intubation With Low Dose Rocuronium During Propofol Anaesthesia in Children With and Without Atropine

The investigators hypothesized that increasing the cardiac output by use of atropine in children might result in a reduction of the intubation time needed to facilitate tracheal intubation.

The investigators hypothesized that increasing the cardiac output by use of atropine in children might result in a reduction of the intubation time needed to facilitate tracheal intubation. Therefore, the purpose of this study was to determine TimeEI with a low dose of esmeron (rocuronium) (0.3 mg.kg-1) for achievement of successful tracheal intubation conditions during intravenous (i.v.) anaesthesia using propofol and alfentanil in children and to determine whether administration of i.v. atropine (atropine sulphate) (10 μg.kg-1) during anaesthesia induction reduced these times.
