Overview
Brief Summary
Previous studies have demonstrated that an experienced ultrasound operator is able to efficiently perform radial arterial puncture on patients where an initial operator failed to puncture arteries via simple palpation.
The objective of this study is to compare "difficult-to-puncture" patients randomized into two groups: one group where ultrasound is used to aid artery localisation, and one group where only palpation is used.
