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.

Detailed description

test

Conditions

• Radial Artery
• Ultrasonography

Interventions

Type	Name	Description
PROCEDURE	RAP palpation only	Skin disinfection by local antiseptic. Identification of the radial artery by palpation. Insertion of the needle positioned at 70 ° with regard to the artery palpated. Check the rise of arterial blood in the syringe.
PROCEDURE	RAP with ultrasound guidance	Skin disinfection by local antiseptic. Application of sterile gel. Identification of the artery via ultrasound vascular probe. Center the artery at the center of the screen. Introduction of the syringe at 70 ° with respect to the probe, in center of visualized zone. Check the rise of arterial blood in the syringe.
