About

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

Full 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.

Trial design

82 participants in 2 patient groups

A group

Description:

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

Treatment:

Other: A group

S group

Description:

S group is the patients without non-overlapping range

Treatment:

Other: S group
