Clinical practice, educational curricula and academic understanding have evolved since then. We aimed to provide a pragmatic and clinically focused narrative review on the current understanding of Plan A blocks and to explore their implementation and signpost future directions.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We conducted a focused literature search for articles of relevance to Plan A blocks.

Delphi studies have supported the inclusion of interscalene brachial plexus, axillary brachial plexus, femoral and sciatic nerve blocks as key techniques. Despite wide dissemination, challenges hindering clinical practice change persist, including resource limitations; lack of confidence; and variable access to structured training. Emerging educational technologies such as simulation, artificial intelligence\u2010assisted ultrasound interpretation and augmented reality offer promise, but remain limited by cost and fidelity.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion<\/jats:title>\n                    <jats:p>The Plan A blocks framework has become an established concept and is accepted widely as a pragmatic, scalable strategy.
