First seen Nov 19, 2025 · Last updated May 16, 2026 · Updated 22 times

Summary

This study tested whether using ultrasound to locate the radial artery (in the wrist) makes blood draws easier for patients whose arteries are hard to feel or where previous attempts failed. 74 adults were randomly assigned to have their blood drawn either with ultrasound guidance or by touch alone. The main goal was to see if the first attempt succeeded more often with ultrasound.
