摘要
Arterial catheterisation in children can be challenging and time-consuming. We aimed to compare the success rates of ultrasound-guided arterial catheterisation utilising the short-axis out-of-plane approach with dynamic needle tip positioning in the radial, dorsalis pedis, and posterior tibial arteries in paediatric patients. We also examined the factors influencing the catheterisation success using dynamic needle tip positioning.Paediatric patients (aged <3 yr) undergoing cardiac surgery were randomly assigned to three groups based on puncture sites: radial artery (Group R), dorsalis pedis artery (Group D), and posterior tibial artery (Group P). The first-attempt and overall success rates of arterial catheterisation were compared, followed by multiple logistic regression analysis (dependent variable: first-attempt success; independent variables: body weight, diameter and depth of the artery, targeted artery, and trisomy 21).The study included 270 subjects (n=90 per group). There was no significant difference in the first-attempt (Group R: 82%, Group D: 76%, and Group P: 81%) and overall success rates (Group R: 94%, Group D: 93%, and Group P: 91%) among the three groups. The diameter of the artery (per 0.1 mm) (odds ratio: 1.32, 95% confidence interval: 1.09-1.60) and trisomy 21 (odds ratio: 0.43, 95% confidence interval: 0.20-0.92) were independent predictors of first-attempt success or failure.The first-attempt and overall success rates of arterial catheterisation of the dorsalis pedis and posterior tibial arteries were not inferior to those in the radial artery when using dynamic needle tip positioning. These two lower extremity peripheral arteries present viable alternative catheterisation sites in paediatric patients.UMIN000042847.
