Can a warm sock or a toothbrush vibration ease newborn heel prick pain?
NCT ID NCT06607575
First seen Sep 15, 2026 · Last updated Sep 16, 2026 · Updated 1 time
Summary
Researchers are testing whether warming a newborn's foot or applying gentle vibration can reduce pain during routine heel blood collection. The trial enrolls 140 healthy newborns and compares a control group with groups that receive warming, vibration, or both. Pain is measured with the N-PASS scale during and after the procedure. The goal is to see if these simple methods help manage a common source of newborn discomfort.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- warming with a heated cotton sock and gentle vibration from a toothbrush
- What this could lead to
- If warming or vibration helps, hospitals could adopt these simple, low-cost steps to make routine newborn heel pricks less painful.
- What could go wrong
- The trial is small and early, so the results may not hold up in larger settings. Warming or vibration might not reduce pain enough to matter, and each method could be uncomfortable or impractical for some newborns.
