Evaluation of ultrasound-guided radial artery cannulation in children

Abstract

US guidance did not facilitate faster cannulation of the radial artery in children in our study.

Real-Time Ultrasound Guidance Facilitates Transradial Access

“…Shiver et al (14) showed in 60 critically ill emergency room patients an improvement in first-pass success rate from 50% to 87% (p ¼ 0.005) and a reduction in time from 314 s versus 107 s (p ¼ 0.0004). In 1 trial, US did not have a benefit, which was felt by the investigators to be due to insufficient experience, with 94% of operators having <5 US-guided procedures (15). These findings are summarized in a meta-analysis, which suggested a 17% absolute improvement (26% to 43%) in firstpass success rate (10).…”

Ultrasound guidance versus direct palpation for radial artery catheterization by expert operators: a randomized trial among Canadian cardiac anesthesiologists

“…15 On the other hand, in another prospective trial involving 152 children by Ganesh et al, US guidance did not facilitate faster cannulation of the radial artery. 24 A possible explanation for this may again relate to operator inexperience. It was noted in the article that experienced operators (supervising consultant anesthesiologists) were successful where an initial inexperienced operator failed.…”

International evidence-based recommendations on ultrasound-guided vascular access

“…Therefore, it is recommended to use ultrasound-guided arterial catheterization routinely in these patients. The experience gained by using ultrasound routinely will be very beneficial in difficult or extreme cases [57].…”
