The Optimal Leg Angulation of Femoral Central Catheterization in Pediatrics

Completed

• Conditions: Femoral Artery Injury; Pediatric Disorder; Emergencies
• Interventions: Other: S group; Other: A group

• Registration Number: NCT03358446
• Lead Sponsor: Samsung Medical Center

Brief Summary

Evaluation for the range of smallest leg angulation with femoral artery and vein overlap with femoral central catheterization in pediatrics.

Detailed Description

In pediatrics, femoral vein catheterization often overlaps with the femoral artery.

In this case, the risk of artery puncture is high, vein collapse when artery puncture 2nd, 3rd times exceeds the success rate of catheterization becomes low. In previous study, comparing 0, 30, and 60 degrees with frog leg position, there was a study that the overlap was the smallest at 60 degrees. A previous study was a simple frog leg position and a study in fragmented predetermined angles. On a continuous measurement, we planned the study under the assumption that there is a more definite range of optimal angulation.

Ultrasound probe in the state of Inguinal crease, we find a part without bifurcation of femoral artery and femoral vein in frog leg position(external rotation + flexion increase). Increase the leg angle and check the vein and arterie relations.

Arm && Interventions

Group	Intervention	Description
S group	S group	S group is the patients without non-overlapping range
A group	A group	Based on the presence of non-overlapping range between femoral artery and vein from the initial observation, the patients were divided into following two groups. A group is the patients with non-overlapping range

Primary Outcome Measures

Name	Time	Method
A range of angles in which arteries and veins do not overlap	Intraoperative ( after anesthesia induction)	The optimal range of leg abduction was defined as the range without overlap in A group and the range presenting that the overlap was less-than half of the diameter of femoral vein in S group.
