[Effect of optimizing anesthetic injecting sequence during induction on fentanyl-induced coughing].

Objective: To observe the effect of optimizing anesthetic injecting sequence during induction on fentanyl-induced coughing.

Methods: One hundred and twenty ASA I or II elective patients undergoing general anesthesia were randomly allocated to optimized group or control group: the optimized group induced with midazolam 0.06 mg/kg, followed by fentanyl 1 mg/kg at 1 min later, vecuronium 0.
