Application of a skin traction method to facilitate ultrasound-guided brachial plexus block in obese patient with short neck

Ultrasound-guided brachial plexus block is difficult to perform in patients who are obese and have a short neck, as a thick subdermal adipose layer makes stable ultrasound probe placement impossible [1]. A skin traction method is reportedly helpful for central venous catheter placement in pediatric cases [2]. Here, we propose the use of the skin traction method to perform brachial plexus block in obese patients.
