Ultrasound beats touch for tough blood draws?
NCT ID NCT01789801
First seen Nov 19, 2025 · Last updated May 20, 2026 · Updated 24 times
Summary
This study tested whether using ultrasound to locate the wrist artery makes drawing blood easier for patients whose arteries are hard to feel. 74 adults who needed an arterial blood sample but had weak pulses or failed previous attempts were split into two groups: one using ultrasound guidance, the other using only touch. The main goal was to see if the first poke succeeded more often with ultrasound.
