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.
为了评估三种不同方法在小儿患者颈内静脉（IJV）置管中的效果，我们对 11 年间接受心血管手术的患者进行了回顾性研究，评估了置管成功率和从麻醉诱导到置管的时间。实时超声引导（USG：90%）的成功率优于解剖标志（AL：76%）或音频多普勒引导（ADG：74%），所需时间 USG （35.0 +/- 13.6 分钟）大于 AL（26.7 +/- 11.2 分钟）或 ADG（29.2 +/- 8.9 分钟）。然而，USG 对于小体重（<5 公斤）患者在可比的手术时间内，成功率高于其他方法。因此，实时 USG 可实现最高的 IJV 置管成功率，但存在显著的时间延迟，而对于小体重亚组，它是最有用的，且无时间延迟。
