Evaluation of the effect of ultrasound-guided dynamic tip positioning technology in radial artery catheterization in children

Objective　To investigate the influence and safety of ultrasound-guided dynamic tippositioning technology on the quality of radial artery catheterization inchildren. Methods　A total of 109children who planned to undergo radial artery catheterization in The FirstAffiliated Hospital of Henan University of Science and Technology from February2019 to February 2021 were selected as the study subjects. According to therandom number table method, they were divided into two groups, including 54patients [30 males and 24 females, aged (2.51±0.48) years] in the control groupwho received radial artery catheterization by touch positioning method, 55patients [32 males and 23 females, aged (2.53±0.44) years] in the observationgroup who were given ultrasound-guided dynamic needle tip positioning techniquefor puncture catheterization. The related indexes of the two groups werecompared. χ² test was usedfor the count data and independent sample t test was used for the measurement data. Results　The first puncture success rate [85.45% (47/55)] and total success rate[96.36% (53/55)] in the observation group were higher than those in the controlgroup [48.15% (26/54) and 64.81% (35/54)] (both P<0.05). The puncture time [(4.12±0.99) min] and puncture times[(1.02±0.31) times] in the observation group were lower than those in thecontrol group [(8.23±1.26) min and (2.18±0.46) times] (both P<0.05). The total incidence ofradial artery hematoma and spasm after puncture in the observation group [3.64%(2/55)] was lower than that in the control group [16.67% (9/54)] (P<0.05). Conclusion　Both touch positioning and ultrasound-guided dynamic needle tippositioning can be used in radial artery catheterization in children, but thelatter has a higher puncture success rate, better quality control indexes, andhigher safety.
