In Group B, children will receive intravenous midazolam (0.05-0.1 mg\u002Fkg) during anesthesia induction.\n\nThe primary outcome of the study is the change in serum cortisol levels, which reflects the physiological stress response. Blood samples will be collected twice: once 10 minutes after anesthesia induction and once 15 minutes after surgery in the post-anesthesia care unit.\n\nIn addition to cortisol levels, the study will assess preoperative anxiety using an observational anxiety scale, postoperative pain using a behavioral pain scoring system, and parental satisfaction using a standardized questionnaire.
