Information about the children and their parents who agreed to participate in the study was recorded on the 'Information Form' 5 minutes before the dressing procedure by the researcher.

The first dressing of all children included in the study after appendectomy was performed by the doctor in the clinic. No distraction method was applied to the children in the control group during dressing. The children in the LM group were dressed while listening to music. The children in the BS group continued to squeeze the ball during the dressing. The children in the MO group were asked to perform mathematical operations given by the nurse. While the dressing was in progress, the pulse and oxygen saturation levels were recorded in the information form by the nurse. At the last stage of dressing, the children were asked to mark the level of pain they experienced during dressing on the VAS, immediately after the sticking plaster was placed on the surgical area. Parents and nurses assessed the pain level of the child during dressing through the VAS.

When the dressing was over, the application of distraction methods was terminated. After the dressing, the child's pulse and oxygen saturation levels were recorded in the information form by the nurse.

Prepared by the researchers, the form involved mathematical operations such as addition, subtraction, multiplication, and division. The difficulty level of the mathematical operations in the form was determined by age groups of children. Accordingly, mathematical operations were divided into 3 groups primary school, secondary school and high school levels.

Visual Analog Scale (VAS) was used for determine pain level in this research. Scale got 0 to 10 points (0 (Good) to 10 (Bad)).
