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%, = 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, < 0.001). While the total catheterization time was similar between the 2 groups (88.1 ± 23 vs. 86.9 ± 46.1 s, = 0.475).
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.
桡动脉置管对儿科麻醉医生来说是一项挑战。本研究的目的是确定改良长轴平面内（MLAX - IP）技术是否能提高儿童桡动脉置管的成功率。
本研究纳入80例需要进行动脉置管的儿童，随机分为MLAX - IP组和动态针尖定位（DNTP）组（每组40例）。分别采用MLAX - IP技术或DNTP技术进行桡动脉置管。
MLAX - IP组首次穿刺成功率高于DNTP组（95%对80%，P = 0.043）。MLAX - IP组动脉成像时间长于DNTP组（19.1±3.1秒对9.6±2.4秒，P < 0.001）。而两组的总置管时间相似（88.1±23秒对86.9±46.1秒，P = 0.475）。
MLAX - IP技术提高了首次穿刺成功率，两组总置管时间相似且穿刺相关并发症较少。
