Background: 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.

- The study compares two ultrasound-guided approaches for central venous catheterization in infants: the long-axis in-plane and a combined short-axis out-of-plane approach.
- Both methods showed similar rates of posterior wall penetration and first-attempt success, with very high overall success rates within 20 minutes.
- Notable differences were observed in scanning and puncture durations, where the combined approach required significantly less time, but the overall procedure durations were not significantly different.
Objectives: The aim of this study was to compare the occurrence of posterior wall puncture between the long-axis in-plane and the short-axis out-of-plane approaches in a randomized controlled trial of pediatric patients who underwent cardiovascular surgery under general anesthesia.
Design: Prospective randomized controlled trial.
Setting: Operating room of Osaka Women's and Children's Hospital.
Background: Prior experience may be important for successful placement of a pulmonary artery catheter (PAC). However, there is no report about the minimum number of the placement to reach acceptable technique for the catheter placement during residency.
Aims: This study was designed to examine quality of the catheter placement and to assess the effect of prior experience.
