The anxiety levels were tested by MYPAS (modified Yale preoperative anxiety scale) at 4 time point s : days before operation, entering operating room, anesthesia induction, 24 hours after operation. The cooperative levels during the anesthesia induction were tested by ICC (induction compliance checklist) at anesthesia induction. Venous blood samples were obtained when coming into the hospital , anesthesia induction, in the operation(20 minutes after incision) and 24 hours after operation for determination of plasma noradrenalin and cortisol. The cases and dosages of the two groups'anesthesia medicine, and the evaluated satisfactive levels of the parents were recorded.
