Ultrasound may take the guesswork out of wrist blood draws
NCT ID NCT01189188
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether using an ultrasound device to locate the radial artery in the wrist helps healthcare workers draw blood on the first try. 74 adults who needed an arterial blood sample took part. Half had the procedure with ultrasound guidance, half without. Researchers measured how many puncture attempts were needed and how much pain patients felt.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- What this could lead to
- If successful, this could make arterial blood draws faster and more comfortable for patients.
- What could go wrong
- This is a small, completed study with only 74 participants, so results may not apply to everyone. The benefit over standard technique may be small.
