The Effect of a Musical Toy (Xylophone) on Pain, Fear, and Parental Satisfaction During Peripheral Intravenous Cannulation in Children Aged 3 to 6 Years

Children in this group will play with a colorful xylophone toy for 5 minutes before and during peripheral intravenous cannulation. A nurse (researcher) will assist the child in playing with the toy to distract them from the procedure. The toy will be cleaned between uses. This non-pharmacological method aims to reduce pain and fear.

Children in this group will receive routine peripheral intravenous cannulation according to standard hospital protocols. No distraction or behavioral intervention will be applied.
