This resource is for educational purposes only. Drug doses and techniques should be verified against current national guidelines, the BNF, and local protocols before clinical use. All regional anaesthesia should be performed by appropriately trained practitioners with resuscitation equipment and 20% Intralipid readily available. In doubt, seek senior/anaesthetic support.
