Background:
Radial artery catheterization is a challenge for anesthetists in the pediatric population. The purpose of this study was to determine whether the modified long-axis in-plane (MLAX-IP) technique increased the success rate of radial artery catheterization in children.
Methods:
This study involved 80 children who required arterial catheterization and were randomly divided into the MLAX-IP group and dynamic needle tip positioning (DNTP) group (40 cases in each group). Radial artery catheterization was performed using either the MLAX-IP technique or the DNTP technique.
Results:
The first-attempt cannulation success rate was higher in the MLAX-IP group than in the DNTP group (95 vs. 80%, P = 0.043). The imaging time of the artery in the MLAX-IP group was longer than in the DNTP group (19.1 ± 3.1 vs. 9.6 ± 2.4 s, P < 0.001). While the total catheterization time was similar between the 2 groups (88.1 ± 23 vs. 86.9 ± 46.1 s, P = 0.475).
Conclusion:
The first-attempt cannulation success rate with the MLAX-IP technique is increased, while the total catheterization time is similar between the 2 groups and puncture-related complications are fewer.

01:11Assessment of radial pulse
The radial pulse, located at the wrist, is often the preferred site for assessing peripheral pulse because of its accessibility and dependability. The process of determining the radial pulse involves several steps:
01:25Assessment of apical radial pulse
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.
