Time-consumption risk of real-time ultrasound-guided internal jugular vein cannulation in pediatric patients: comparison with two conventional techniques

To assess the efficacy of three different methods for internal jugular vein (IJV) cannulation in pediatric patients, we conducted a review of patients undergoing cardiovascular surgery over an 11-year period, in which success rates for cannulation and time from induction of anesthesia to cannulation were evaluated. The success rate was better for real-time ultrasound guidance (USG: 90%) than for anatomic landmarks (AL: 76%) or audio-Doppler guidance (ADG: 74%) and the time required was greater for USG (35.0 ± 13.6 min) than for AL (26.7 ± 11.2 min) or ADG (29.2 ± 8.9 min). However, USG resulted in a higher success rate than the other methods with comparable procedure time for smaller-body-weight (<5 kg) patients. Thus real-time USG leads to the highest success rate for IJV cannulation but with a significant time delay, whereas it was the most useful without time delay for the smaller-body-weight subgroup.
