Key result
The supraclavicular approach demonstrated better needle visualization and a higher success rate than the retroclavicular approach, but had a shorter duration of sensory and motor block.
Why the study?
To compare needle visualisation, success rate, and timing of sensory and motor block onset between supraclavicular and retroclavicular brachial plexus blocks.
Does the supraclavicular approach improve needle visualization, success rate, and block timing compared to the retroclavicular approach in patients requiring brachial plexus block?
Does the supraclavicular approach improve needle visualization, success rate, and block timing compared to the retroclavicular approach in patients requiring brachial plexus block?
The supraclavicular approach offers better needle visualization and success rates but shorter block duration compared to the retroclavicular approach for brachial plexus blocks.
Supraclavicular approach may favor visualization and success in brachial plexus block; leaves open optimal selection pending prospective trials on duration.
Background: Five roots, three trunks, six divisions (three anterior and three posterior), three cords, and five branches make up the brachial plexus. Supraclavicular, infraclavicular (ICB), or axillary brachial plexus blocks are often used in regional anaesthesia for distal upper limb operations. The well-known and straightforward retroclavicular route for brachial plexus anaesthesia is used. One of the methods for numbing the brachial plexus is the retroclavicular block. In this method, the needle was placed above the clavicle's midpoint. It is a great option for hand and elbow surgery. Objective: This review article compared the needle visualisation, success rate, and timing of the beginning of the sensory and motor block in supraclavicular and retroclavicular brachial plexus blocks. Methods: Supraclavicular approach, Retroclavicular approach and Brachial plexus block were searched for in PubMed, Google and Google Scholar. Only the most current or comprehensive study was included after the authors thoroughly filtered references from the pertinent literature, which comprised all the recognised studies and reviews. Conclusion: Supraclavicular approach has better needle visualization than retroclavicular approach and better success rate but has shorter duration of both sensory and motor block.

A 2023 study conducted a review in distal upper limb operations. Supraclavicular approach vs. Retroclavicular approach was evaluated on needle visualisation, success rate, and timing of the beginning of the sensory and motor block. The supraclavicular approach demonstrated better needle visualization and a higher success rate than the retroclavicular approach, but had a shorter duration of sensory and motor block.
