The primary aim of this observational study is to evaluate the effect of playing a mother's voice to a child while the patient is being awakened from anesthesia on postoperative delirium. For this purpose, a recording of the mother's voice will be prepared before surgery. In this recording, the mother will reassure the child that they are safe and encourage them to remain calm. This recording will then be played to the patient during the awakening phase from anesthesia. The frequency of postoperative delirium in participants who were awakened by the voice recording will be compared with that of the patient group who were awakened without the voice recording.

In this study, mothers' anxiety levels will be measured and recorded using the STAI 1 and 2 questionnaires. Children's postoperative anxiety will be recorded using the modified Yale questionnaire and the PAED. Additionally, the FLACC scale will be used to record information in postoperative children.
