Summary

Aim: This study aimed to compare the effects of cartoon-based audiovisual distraction and bubble-machine-based visual distraction on pain and fear during venipuncture in preschool children.

Methods: This randomized controlled trial included 123 children aged 3-6 years who underwent venipuncture between February and April 2026. Participants were randomly assigned to a cartoon-based audiovisual distraction group (n = 41), a bubble-machine-based visual distraction group (n = 41), or a control group (n = 41). Children in the cartoon group watched Oggy Oggy on a tablet, while those in the bubble-machine group were exposed to bubbles generated by an automated bubble machine during venipuncture. The control group received routine care. Pain and fear were assessed by the children, parents, and nurse using the Wong-Baker FACES Pain Rating Scale and Children's Fear Scale.

PROCEDURE

Implementation of Bubble Machine

Implementation of Bubble Machine: It is defined as the use of a device called Bubble Machine. Children are exposed to bubbles generated by an automated bubble machine during venipuncture. Researcher operate the bubble machine and generate bubbles within the child's visual field to attract and maintain the child's attention during the procedure. A child-friendly plastic bubble machine is used, and a tear-free baby shampoo suitable for children was used as the bubble solution. The device is positioned at an appropriate distance from the child so that it did not interfere with the nurse's access to the venipuncture site. The bubble machine iss operated throughout the venipuncture procedure. Pain and fear before and during the procedure are evaluated by the researcher, the nurse, and the child's parent.

PROCEDURE

Implementation of Cartoon

Implementation of Cartoon: It is defined as the use of a called Oggy Oggy. Children watch the predetermined Cartoon-Oggy Oggy on a tablet during venipuncture. The cartoon is selected as an age-appropriate audiovisual distraction and is presented in Turkish. It contains dynamic, colorful, and music-rich scenes intended to attract and maintain children's attention during the procedure. Researcher operate the tablet and ensure that the child could comfortably view the cartoon while the nurse performed venipuncture. The cartoon is played throughout the venipuncture procedure. Pain and fear before and during the procedure are evaluated by the researcher, the nurse, and the child's parent.
