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.

Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Single Blind (Investigator)
||Study of Intubation Time Required for Excellent Tracheal Intubation With Low Dose Rocuronium During Propofol Anaesthesia in Children With and Without Atropine
Primary Outcome Measures:
- intubation time [ Time Frame: intubating condition at 120 seconds from rocuronium injection ] [ Designated as safety issue: Yes ]
Tracheal intubation was attempted was predetermined according to the up-and-down method, starting with 120 s, in both groups. If intubation was successful (unsuccessful), the assigned intubation time was decreased (increased) by one interval for the next patients in that group, respectively. In this study, the investigators adopted 69, 83, 99, 120, 144, 173, and 208 s, since these intubation times have equal intervals (0.08) on a logarithmic scale.

Experimental: Control group
Anaesthesia was induced with alfentanil 10 μg.kg-1, propofol 2.5 mg.kg-1 and rocuronium 0.3 mg.kg-1.And receive normal saline for control group
Anaesthesia was induced with alfentanil 10 μg.kg-1, propofol 2.5 mg.kg-1 and rocuronium 0.3 mg.kg-1.
Atropine(atropine sulphate) 10 μg.kg-1, intravenous injection during induction After 120 sec of atropine injection, record intubating condition
Other Name: Atropine sulfate
Active Comparator: Atropine group
Anaesthesia was induced with alfentanil 10 μg.kg-1, propofol 2.5 mg.kg-1 and rocuronium 0.3 mg.kg-1. And receive atropine (atropine sulfate) 10 μg.kg-1 for atropine group.
Drug: Normal saline
Anaesthesia was induced with alfentanil 10 μg.kg-1, propofol 2.5 mg.kg-1 and rocuronium 0.3 mg.kg-1 Normal saline intravenous injection during anesthetic induction After 120 sec of normal saline injection, record intubating condition
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.
