Can a warm wrist make baby arterial lines easier?
NCT ID NCT06041685
First seen Sep 16, 2026 · Last updated Sep 17, 2026 · Updated 1 time
Summary
Researchers are testing whether warming the wrist with a forced-air warmer helps doctors place arterial catheters on the first try in babies and toddlers having heart surgery. The trial includes 126 children aged 2 years or younger. Half receive local warming before the procedure, and half do not. The team measures first-attempt success and uses ultrasound to see if warming widens the artery.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- local warming of the skin using a forced air warmer
- What this could lead to
- If warming helps, it could give doctors a simple, low-risk way to place arterial lines more reliably in young children, reducing repeated needle sticks.
- What could go wrong
- The trial is small and focused on one hospital, so the results may not apply everywhere. Warming might not improve success rates, and it could cause minor skin discomfort or burns if not monitored.
