The ultrasound (US)-guided supraclavicular approach to subclavian vein (Sup-SCV) catheterisation in children has recently been described and evaluated in a small cohort. The aim of this study was to assess this technique in a large paediatric cohort including neonates.

We conducted a prospective observational study between November 2010 and December 2013 which included 615 children divided into two groups according to their weight: Group 1≤5kg (n=124), Group 2>5kg (n=491). All procedures were performed under general anaesthesia by an anaesthesiologist or a supervised resident. The success rates of catheter insertion, the number of punctures required, the procedure time, and the complication rates were analysed.

Sup-SCV catheterisation was successful in 98% of the cases and was higher in Group 2 than in Group 1 (99.4% versus 92.7%, P<0.001). The success rate after the first attempt was higher and the incidence of multiple attempts (≥3 punctures) was lower in Group 2 than in Group 1 (84.2% versus 64.5%, P<0.001 and 4.5% versus 19.4%, P<0.001). The success rate was similar between right and left cannulations (P=0.404), and according to physician experience (P=1.000). Procedure time was fast in both groups with a median time for all procedures of 40 seconds [30–90]. Among the procedures recorded, only five arterial punctures and no cases of pneumothorax were observed.

US-guided Sup-SCV catheterisation appears to be fast and safe in children and neonates, even if it remains a little more difficult to achieve in lower-weight patients.
