Study Arms:
- Midazolam (Type: None): Demizolam, once on the operation day, usually ordered 15 minutes before strabismus operation by another anesthesiologist who is charged to perform anesthesia who is not related with the trial.The maximum dose of 0.5 mg/kg midazolam is given orally with cherry juice of maximum 5 ml. in Yeditepe University Hospital to the pediatric patients by the anesthesiologists.~In all groups patients are not selected to the groups and premedication and doses are not given by the investigator, they grouped according to the premedication given by the anesthesiologists, after the operation retrospectively.
- Midazolam&Hydroxyzine dihydrochloride1/2 (Type: None): Midazolam and Hydroxyzine dihydrochloride, once on the operation day, usually ordered 15 minutes before strabismus operation by another anesthesiologist who is charged to perform anesthesia who is not related with the trial.The maximum dose of 0.5 mg/kg midazolam is given orally with hydroxyzine dihydrochloride (dose of 0.5 mg/kg) in Yeditepe University Hospital to the pediatric patients by the anesthesiologists.~In all groups patients are not selected to the groups and premedication doses are not given by the investigator, they grouped according to the premedication given by the anesthesiologists, after the operation retrospectively.
- Midazolam&Hydroxyzine dihydrochloride (Type: None): Midazolam and Hydroxyzine dihydrochloride, once on the operation day, usually ordered 15 minutes before strabismus operation by another anesthesiologist who is charged to perform anesthesia who is not related with the trial.The maximum dose of 0.5 mg/kg midazolam is given orally with the maximum dose of 1mg/kg hydroxyzine dihydrochloride in Yeditepe University Hospital to the pediatric patients by the anesthesiologists.~In all groups patients are not selected to the groups and premedication doses are not given by the investigator, they grouped according to the premedication given by the anesthesiologists, after the operation retrospectively.
