Abstract |
BACKGROUND The purpose of this study was two fold; first, to determine the incidence and type of withdrawal movement associated with IV injection of rocuronium in pediatric patients; and second, to determine whether pretreatment with IV lidocaine affects the incidence of movement associated with rocuronium administration in pediatric patients. METHODS Forty-two pediatric patients were randomly assigned to two groups. After general anesthesia was induced with thiopental sodium 5 mg/kg and manual occlusion of venous inflow was performed, one group of patients received 0.1 ml/kg 1% lidocaine IV. A second group received 0.1 ml/kg of normal saline as a placebo control. Venous inflow occlusion was held for 5 seconds, and immediately followed by the injection of rocuronium 0.6 mg/kg IV. The patient's response to rocuronium injection was graded using a 5-point scale. RESULTS We observed that the incidence of movement was 100% in the placebo group and was significantly decreased to 28.8% in the group pretreated with lidocaine (P<0.001). CONCLUSIONS Withdrawal movement on injection of rocuronium in pediatric patients can be decreased or prevented by pretreatment with IV lidocaine. |
