Radial Artery, Vascular Catheters
Brief summary
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).
Interventions
PROCEDUREGuidewire-assist
catheter insertion with guidewire-assist(catheter over guidewire)
PROCEDUREDirect
catheter insertion without guidewire assist(catheter over needle)

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| success rate at 1st attempt (%) | from arterial cannulation to successful invasive BP monitoring (up to 1 hour) | successful catheter insertion after obtaining 1st blood flush in angiocatheter. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| total elapsed time (seconds) | from arterial cannulation to successful invasive BP monitoring (up to 1 hour) | total time for successful cannulation. |
| number of total cannulation attempts (number) | from arterial cannulation to successful invasive BP monitoring (up to 1 hour) | number of total attempts until successful cannulation. (1 attempt = 1 blood flush) |
| number of total catheter used (number) | from arterial cannulation to successful invasive BP monitoring (up to 1 hour) | number of total catheter used until successful cannulation. |
| malfunction of arterial line | from the start of invasive BP monitoring until the end of anesthesia (up to 1 day) | pressure monitoring, blood sampling |
| complications | from the arterial cannulation until the end of anesthesia (up to 1 day) | hematoma, ischemia |
