A novel method for ultrasound-guided radial artery cannulation in neonates by trainee anaesthesiologists A randomised controlled trial

摘要

BACKGROUND The modified dynamic needle tip positioning (MDNTP) technique for ultrasound-guided radial artery cannulation (MDNTP-US technique) in neonates can be technically challenging for trainee anaesthesiologists. We hypothesised that by associating the MDNTP-US technique with hypodermic 0.9% sodium chloride (Saline MDNTP-US technique), which increases the subcutaneous radial artery depth, the procedure would become easier for trainee anaesthesiologists.
