Details and patient eligibility

About

In neonate and infant, radial artery cannulation may be challenging and multiple attempts are required because of the small diameter.

The invastigators will compare the success rates of radial arterial cannulation with a guidewire-assisted technique and the direct technique in pediatric patient(<1yr).

Enrollment: 90 patients

Sex: All

Ages: Under 1 year old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Pediatric patients undergoing general anesthesia with arterial cannulation (for hemodynamic monitoring or blood sampling)

Exclusion criteria

• Skin lesion, infection, hematoma, recent cannulation at cannulation site
• Unstable radial pulse (d/t unstable vital sign, or arrhythmias)

Trial design

Primary purpose: Treatment

Allocation: Randomized

Interventional model: Parallel Assignment

Masking: Single Blind
