ASA I-II 112 pediatric patients will recruit who underwent adenoidectomy-tonsillectomy surgery. Propofol 1 mg/kg + ketamin1 mg/kg (1/1 ratio) for group I; propofol 1,5 mg/kg + ketamin 0,75 mg/kg (2/1 ratio) for group II; propofol 2 mg/kg +ketamin 0,66 mg/kg (3/1 ratio) for group III; propofol 3 mg/kg will perform for anesthesia induction. General anesthesia will maintenance with sevoflurane 1-2% and O2/N2O mixture. Morphine 0.1mg/kg IV will be apply for postoperative analgesia at 10 min of anesthesia. Extubation time, length of stay in PACU, Watcha score, FLACC score will record. Than all data will statistically analyse.

ASA I-II 112 pediatric patients will recruit who underwent adenoidectomy-tonsillectomy surgery in this randomised controlled study. The participants will divide into the 4 groups with computered random generation. The Different combination of propofol+ketamin mixture will apply at the induction of anesthesia. The groups will assign as group I,II, III and IV. Propofol 1 mg/kg + ketamin1 mg/kg (1/1 ratio) for group I; propofol 1,5 mg/kg + ketamin 0,75 mg/kg (2/1 ratio) for group II; propofol 2 mg/kg +ketamin 0,66 mg/kg (3/1 ratio) for group III; propofol 3 mg/kg will perform for anesthesia induction. Fentanyl 1 microgram per kg and rocuronium 0.6 mg/kg will apply for anesthesia induction to the all participants. General anesthesia will maintenance with sevoflurane 1-2% and O2/N2O mixture. Morphine 0.1mg/kg IV will be apply for postoperative analgesia at 10 min of anesthesia. Extubation time, length of stay in PACU, Watcha score, FLACC score will record. Than all data will statistically analyse.
