Supraclavicular approach for subclavian vein catheterization in pediatric anesthesia: The reborn of an ancient technique with the ultrasound's assistance

The insertion of a central venous catheter is a procedure frequently performed in paediatric anaesthesia. The most frequent approach for this procedure is the internal jugular vein. However, some specific factors in children, such as the short neck and the easy collapse of this vein, which is accentuated in situations such as hypovolaemia and changes in the respiratory pattern, can lead to greater difficulty. The supraclavicular approach of the subclavian vein was described more than 50 years ago. However, it is not often considered nowadays, even after the introduction of ultrasound, and despite the obvious advantages with respect to the internal jugular approach due to the lower incidence of thrombosis and infection. This document reviews the considerations of the supraclavicular approach according to the available evidence in paediatric anaesthesia, discusses the feasibility and safety of the procedure, and finally describes the technique of ultrasound--guided puncture.
