Description

This study is a four-arm, parallel-group randomized controlled trial involving children aged 5-10 years undergoing blood draw in a pediatric phlebotomy unit. The study aims to compare three nonpharmacological methods involving different mechanisms: active distraction through pinwheel blowing, passive visual distraction through 3D hologram viewing, and rhythmic oral and gustatory stimulation through flavored gum chewing.

Eligible children will be assigned to the study groups in a 1:1:1:1 ratio using block randomization stratified by sex (female or male) and age group (5-7 or 8-10 years). A block size of four will be used within each stratum.

In the pinwheel blowing group, children will begin blowing a colorful handheld pinwheel one minute before the blood draw and continue until the procedure is completed. In the 3D hologram viewing group, children will watch an age-appropriate holographic video featuring colorful flying butterflies, beginning one minute before the blood draw and continuing until the procedure is completed. In the gum chewing group, children will select a flavored sugar-free gum, begin chewing it one minute before the blood draw, and continue throughout the procedure. Children in the control group will receive the routine blood draw procedure without any additional pharmacological or nonpharmacological pain-relieving intervention. The accompanying parent will remain with the child throughout the procedure.

All blood draws will be performed by the same nurse, who has at least five years of pediatric phlebotomy experience, using a standardized procedure. Pain experienced during the blood draw will be assessed using the Wong-Baker FACES Pain Rating Scale, which ranges from 0 to 10. Fear will be assessed using the Children's Fear Scale, which ranges from 0 to 4. Immediately after the procedure, pain and fear will be rated independently by the child, the accompanying parent, and an independent observer nurse. Parental satisfaction will be evaluated using a single-item numerical rating scale ranging from 1 to 10.

Because of the visible nature of the interventions, the children, parents, researcher delivering the interventions, phlebotomy nurse, and observer nurse cannot be blinded to group allocation.
