Guidewire-assisted Radial A-line in Neonate and Infant

Not Applicable

Completed

• Conditions: Arterial Line
• Interventions: Procedure: Guidewire-assist; Procedure: Direct

• Registration Number: NCT03217019
• Lead Sponsor: Seoul National University Hospital

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).

Arm && Interventions

Group	Intervention	Description
Guidewire	Guidewire-assist	1. Radial artery puncture with direct radial pulse palpation. 2. 24G angiocatheter insertion with guidewire-assist. (Catheter over guidewire)
Direct	Direct	1. Radial artery puncture with direct radial pulse palpation. 2. 24G angiocatheter insertion without guidewire-assist. (Catheter over needle)

Primary Outcome Measures

Name	Time	Method
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 Outcome Measures

Name	Time	Method
total elapsed time (seconds)	from arterial cannulation to successful invasive BP monitoring (up to 1 hour)	total time for successful cannulation.
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.
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)
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
