Can a vibrating dolphin toy calm kids during blood draws?
NCT ID NCT07816965
First seen Sep 14, 2026 · Last updated Sep 15, 2026 · Updated 1 time
Summary
Researchers are testing whether a vibrating dolphin-shaped massage device or tablet-based digital storytelling reduces pain and fear in children aged 3 to 6 during blood collection. The trial assigns children to one of these two distraction methods or to a control group. Parents, nurses, and researchers rate each child's pain and fear using standard scales. The goal is to see whether these simple distractions help compared with usual care.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- A vibrating dolphin-shaped massage device and tablet-based digital storytelling
- What this could lead to
- If these distractions help, clinics could adopt simple, low-cost tools to make blood draws less distressing for young children.
- What could go wrong
- Distraction may not reduce pain or fear more than usual care, and results in 3 to 6 year olds may not apply to other ages or settings.
