Does ultrasound-guided supraclavicular vs infraclavicular brachial plexus block in children?
(i) Ultrasound-guided supraclavicular and infraclavicular brachial plexus blocks are effective in children. (ii) There has been no pneumothorax in 40 US-guided supraclavicular brachial plexus blocks performed by anaesthesiologists already trained in US-guided regional anaesthesia using an IP technique in children > or =5 years old. (iii) In this study, the supraclavicular approach of the brachial plexus was faster to perform than the infraclavicular one.
