Abstract
The brachial plexus block can be performed through several approaches. The recently described ultrasound-guided costoclavicular block at the costoclavicular space has gained popularity, presenting promising results for upper limb anaesthesia and postoperative analgesia. This block comes as an alternative to the traditional infraclavicular approach, with results suggesting improved block quality and reduced risk of complications. This article presents a narrative review of the literature and the current evidence available. A bibliographic search was conducted in the database PubMed and relevant articles published between 2015 and December 2020 to this topic were selected.
