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.
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.
The first-attempt cannulation success rate was higher in the MLAX-IP group than in the DNTP group (95 vs. 80%,
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.
