Title: Ultrasound-Guided Vascular Puncture and Catheterization
Brief Summary: To assess and improve the safety and success rate of vascular puncture and catheterization using ultrasound-guided methods.


Options:
A: Inclusion Criteria:

* 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

Exclusion Criteria:

* The patient is participating in another study
* The patient is in an exclusion period determined by a previous 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
B: Inclusion Criteria:

1. Age ≥ 18 years.
2. The distal and proximal radial artery must be palpable and non-occlusive flow must be confirmed by (Doppler) ultrasound.
3. Patient should be able to comply with the protocol.
4. Provide written informed consent before study participation

Exclusion Criteria:

1. Obligatory femoral or forearm radial access
2. Previous ipsilateral forearm radial artery occlusion.
3. Patient on therapeutic oral anticoagulation.
4. Very large hand/wrist anatomy that will preclude using the available hemostatic radial bands.
5. Enrolment in another study that competes or interferes with this study.
6. Poor clinical condition like cardiogenic shock, which prohibits pre- and post-procedural function tests.
7. Subject with planned complex PCI or procedure necessitating multiple intervention.
8. Any other condition or co-morbidity which, in the opinion of the investigator or operator, may pose a significant hazard to the subject if he or she is enrolled in the study.
9. History of stroke with residual deficit that affects hand function.
10. Previous radial artery catheterization within 1 year.
C: Inclusion Criteria:

* Age above 18 years old.
* Scheduled for selective surgery.
* Requirement of perioperative vascular puncture and catheterization.
* American standard of anesthesia level I-IV.

Exclusion Criteria:

* Contraindication to vascular puncture or catheterization.
* Occlusion or thrombosis of target vessel evaluated by ultrasound.
* Refuse or disagreement from participants.
D: Inclusion Criteria:

* Admission of the first degree relatives of the patients and if the patient can give consent
* Patients over 18
* Non-pregnant patients
* Patients without inotropic/vasopressor support
* Patients who do not have contraindications for radial artery cannulation (thrombosis in the distal region, a focus of infection at the site of entry, lack of adequate collateral flow in the Allen test, peripheral vascular diseases \[eg, Raynaud's disease)\]

Exclusion Criteria:

* Patient/Patient's first degree relatives refuse to work
* Patients under 18
* Pregnant patients
* Patients with contraindications for radial artery cannulation (thrombosis in the distal region, a focus of infection at the site of entry, lack of adequate collateral flow in the Allen test, peripheral vascular diseases \[eg, Raynaud's disease)\]
* Patient's inotropic/vasopressor support
