Background:The injection of rocuronium causes pain and withdrawal responses.This study was designed to determine an optimal dose of alfentanil to prevent the withdrawal responses associated with injection of rocuronium in children.
Methods:One hundred and ten ASA physical status I and II pediatric patients were randomly allocated into four groups; Group C (control; normal saline 3 ml, n = 28), Group A5 (alfentanil 5?g/kg, n = 28), Group A10 (alfentanil 10?g/kg, n = 27) and Group A15 (alfentanil 15?g/kg, n = 27).After the induction of anesthesia with 5 mg/kg of thiopental sodium, the test drug was injected over 20 seconds, respectively.After one minute, rocuronium 0.6 mg/kg was injected over 5 seconds.The patient’s response after injection was graded using a four-point scale.Additionally, the mean arterial pressure and heart rate were recorded upon arrival in the operating room, as well as 1 min before and 1 min after tracheal intubation.
Results:The incidence of withdrawal responses was 96%, 61%, 19% and 19% in groups C, A5, A10 and A15, respectively.The incidence and severity of withdrawal responses in group A10 and A15 were lower than group C and A5.
Conclusions:After thiopental injection, alfentanil 10?g/kg prevent the withdrawal responses on injecting rocuronium in pediatric patients.
