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.

Study Arms (2)
Palpation only
ACTIVE COMPARATORPatients randomized to this arm will have radial artery puncture via palpation of arteries. Intervention: RAP palpation only
Ultrasound guidance
EXPERIMENTALPatients randomized to this arm will have radial artery puncture with ultrasound guidance for artery localisation. Intervention: RAP with ultrasound guidance
Interventions
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.
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.
Eligibility Criteria
You may qualify if:
- The patient must have given his/her informed and signed consent
- The patient must be insured or beneficiary of a health insurance plan
- The patient's health status necessitates an arterial blood sample AND his/her radial arteries are deemed unpalpable OR two previous attempts at radial arterial puncture by a nurse resulted in failure
You may not qualify if:
- The patient is participating in another study
- The patient is under judicial protection, or any kind of guardianship
- The patient refuses to sign the consent
- It is impossible to correctly inform the patient
- The patient is pregnant, parturient, or breastfeeding
- Arterial puncture is required on femoral, humeral or axillary arteries
- The patient is in cardiac arrest
- The patient has known circulatory problems, ischemia, local infection
- The patient has a severe bleeding or hemostasis disorder (hemophilia, hypoprothrombinemia, platelets \<50,000)
- The patient is an upper limb amputee, or his/her arm is in a cast
- The patient has known allergies to methyl or propylbenzoate, propylene glycol or chlorexhidine gluconate
